Skin turgor No diagnostic value
Physiological Response to fluid challenge Changes in physiological parameters eg MAP HR
CVP after rapid administration of intravenous fluid over a short time
No data on the optimum technique or its diagnostic reliability
Physiological Response to Passive Leg raising Moving the patient from a semi-recumbent position
to a supine position with passive elevation of the legs to 45ordm above the horizontal
Maximal response is seen within 30-60s Descending aortic blood flow of ge10 or
echocardiographic subaortic flow of ge12 ---- fluid responsiveness
Utility of PLR outside the critical care environment is questionable
Clinical Assessment of Volume Status
AKI a competency network Academy of Medical Royal College 2011
JVP Indication of the pressure in the right atrium
NOT a direct measure of volume A measurement of gt3 cm from sternal angle (gt8 cm from
RA) is taken as evidence of high RA pressure in normal patients
Many conditions that can result in an elevated JVP eg RV failure TR or TS pericardial effusion or constrictive pericarditis SVC obstruction Volume overload
J Gen Intern Med 200217(11)852-6Chest 2008134(1)172-8
Am J Med198783(5)905-8
This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients
RA distance to be 8 cm 97 cm and 98 cm at 30 45 and 60 degrees elevation respectively There is considerable inter-subject variability with dependent variables including age smoking status and AP chest diameter

Differentiating Prerenal vs Intrinsic Renal
FENa () = UNa x SCr x 100
SNa x UCr
FEUrea () = Uurea x SCr x 100
BUN x UCr
None of the above criteria for the diagnosis of prerenal disease may be present in a patient with underlying
renal disease
No recent diuretics
In the absence of hemorrhagic shock use isotonic crystalloids rather than colloids (albumin or starches) as initial management for expansion of intravascular volume
Use of vasopressors in conjunction with fluids in patients with vasomotor shock
Use protocol-based management of hemodynamic and oxygenation parameters to prevent development or worsening of AKI in high-risk patients in the perioperative setting or in patients with septic shock

Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Use continuous and intermittent RRT as complementary therapies in AKI patients
Use CRRT rather than standard intermittent RRT for hemodynamically unstable patients
Use CRRT rather than intermittent RRT for AKI patients with acute brain injury or other causes of increased intracranial pressure or generalized brain edema
Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

Cardiorenal Syndrome
J Am Coll Cardiol 2008521527-1539
Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients
RA distance to be 8 cm 97 cm and 98 cm at 30 45 and 60 degrees elevation respectively There is considerable inter-subject variability with dependent variables including age smoking status and AP chest diameter

No recent diuretics
In the absence of hemorrhagic shock use isotonic crystalloids rather than colloids (albumin or starches) as initial management for expansion of intravascular volume
Use of vasopressors in conjunction with fluids in patients with vasomotor shock
Use protocol-based management of hemodynamic and oxygenation parameters to prevent development or worsening of AKI in high-risk patients in the perioperative setting or in patients with septic shock

Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

A 24 year old wakes up in a bathtub of ice water Scrawled on the bathroom mirror in blood is a message that both of her kidneys were removed and sold On exam she has bilateral nephrectomy scars and an ultrasound confirms absence of both kidneys She has been anuric since a foley was placed 14 hours ago her creatinine is 18
A 62 year old star has arthritis and HT She presents to her primary care doctor with symptoms of fatigue since starting ramipril for her blood pressure Her medications include ibuprofen 800 mg tid HCTZ 25 mg qd simvastatin 40 mg qd and ramipril 10 mg qd Her labs show a Cr of 32 (baseline 12) K of 66 She urinated a ldquonormal amountrdquo prior to coming to the office
A 57 year old british comedian is admitted for decompensated heart failure His baseline creatinine is 14 On admission his creatinine is 22 He is given furosemide and responds well His oxygen requirement decreases most of his edema improves but his creatinine has gone up to 32 His urine output in the last 8 hours is 460 mL

AKI a competency network Academy of Medical Royal College 2011
Skin turgor No diagnostic value
Physiological Response to fluid challenge Changes in physiological parameters eg MAP HR
CVP after rapid administration of intravenous fluid over a short time
No data on the optimum technique or its diagnostic reliability
Physiological Response to Passive Leg raising Moving the patient from a semi-recumbent position
to a supine position with passive elevation of the legs to 45ordm above the horizontal
Maximal response is seen within 30-60s Descending aortic blood flow of ge10 or
echocardiographic subaortic flow of ge12 ---- fluid responsiveness
Utility of PLR outside the critical care environment is questionable
Clinical Assessment of Volume Status
AKI a competency network Academy of Medical Royal College 2011
JVP Indication of the pressure in the right atrium
NOT a direct measure of volume A measurement of gt3 cm from sternal angle (gt8 cm from
RA) is taken as evidence of high RA pressure in normal patients
Many conditions that can result in an elevated JVP eg RV failure TR or TS pericardial effusion or constrictive pericarditis SVC obstruction Volume overload
J Gen Intern Med 200217(11)852-6Chest 2008134(1)172-8
Am J Med198783(5)905-8
This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients
RA distance to be 8 cm 97 cm and 98 cm at 30 45 and 60 degrees elevation respectively There is considerable inter-subject variability with dependent variables including age smoking status and AP chest diameter

Differentiating Prerenal vs Intrinsic Renal
FENa () = UNa x SCr x 100
SNa x UCr
FEUrea () = Uurea x SCr x 100
BUN x UCr
None of the above criteria for the diagnosis of prerenal disease may be present in a patient with underlying
renal disease
No recent diuretics
In the absence of hemorrhagic shock use isotonic crystalloids rather than colloids (albumin or starches) as initial management for expansion of intravascular volume
Use of vasopressors in conjunction with fluids in patients with vasomotor shock
Use protocol-based management of hemodynamic and oxygenation parameters to prevent development or worsening of AKI in high-risk patients in the perioperative setting or in patients with septic shock

Achieve a total energy intake of 20ndash30 kcalkgd in patients with any stage of AKI
Avoid restriction of protein intake with the aim of preventing or delaying initiation of RRT
Provide nutrition preferentially via enteral route in patients with AKI
Administer protein of 08ndash10 gkgd in noncatabolic AKI patients without need
for dialysis 10ndash15 gkgd in patients with AKI on RRT up to 17 gkgd in patients on CRRT and in
hypercatabolic patients

Effect of Low-dose Dopamine on Need for RRT
Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Use continuous and intermittent RRT as complementary therapies in AKI patients
Use CRRT rather than standard intermittent RRT for hemodynamically unstable patients
Use CRRT rather than intermittent RRT for AKI patients with acute brain injury or other causes of increased intracranial pressure or generalized brain edema
Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

Cardiorenal Syndrome
J Am Coll Cardiol 2008521527-1539
Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

JVP Indication of the pressure in the right atrium
NOT a direct measure of volume A measurement of gt3 cm from sternal angle (gt8 cm from
RA) is taken as evidence of high RA pressure in normal patients
Many conditions that can result in an elevated JVP eg RV failure TR or TS pericardial effusion or constrictive pericarditis SVC obstruction Volume overload
J Gen Intern Med 200217(11)852-6Chest 2008134(1)172-8
Am J Med198783(5)905-8
This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients
RA distance to be 8 cm 97 cm and 98 cm at 30 45 and 60 degrees elevation respectively There is considerable inter-subject variability with dependent variables including age smoking status and AP chest diameter

No recent diuretics
In the absence of hemorrhagic shock use isotonic crystalloids rather than colloids (albumin or starches) as initial management for expansion of intravascular volume
Use of vasopressors in conjunction with fluids in patients with vasomotor shock
Use protocol-based management of hemodynamic and oxygenation parameters to prevent development or worsening of AKI in high-risk patients in the perioperative setting or in patients with septic shock

Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Use CRRT rather than intermittent RRT for AKI patients with acute brain injury or other causes of increased intracranial pressure or generalized brain edema
Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

J Am Coll Cardiol 2008521527-1539
Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen

Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

Skin turgor No diagnostic value
Physiological Response to fluid challenge Changes in physiological parameters eg MAP HR
CVP after rapid administration of intravenous fluid over a short time
No data on the optimum technique or its diagnostic reliability
Physiological Response to Passive Leg raising Moving the patient from a semi-recumbent position
to a supine position with passive elevation of the legs to 45ordm above the horizontal
Maximal response is seen within 30-60s Descending aortic blood flow of ge10 or
echocardiographic subaortic flow of ge12 ---- fluid responsiveness
Utility of PLR outside the critical care environment is questionable
Clinical Assessment of Volume Status
AKI a competency network Academy of Medical Royal College 2011
JVP Indication of the pressure in the right atrium
NOT a direct measure of volume A measurement of gt3 cm from sternal angle (gt8 cm from

This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients
RA distance to be 8 cm 97 cm and 98 cm at 30 45 and 60 degrees elevation respectively There is considerable inter-subject variability with dependent variables including age smoking status and AP chest diameter

Differentiating Prerenal vs Intrinsic Renal
FENa () = UNa x SCr x 100
SNa x UCr
FEUrea () = Uurea x SCr x 100
BUN x UCr
None of the above criteria for the diagnosis of prerenal disease may be present in a patient with underlying
renal disease
No recent diuretics
In the absence of hemorrhagic shock use isotonic crystalloids rather than colloids (albumin or starches) as initial management for expansion of intravascular volume
Use of vasopressors in conjunction with fluids in patients with vasomotor shock
Use protocol-based management of hemodynamic and oxygenation parameters to prevent development or worsening of AKI in high-risk patients in the perioperative setting or in patients with septic shock

Effect of Low-dose Dopamine on Need for RRT
Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Use continuous and intermittent RRT as complementary therapies in AKI patients
Use CRRT rather than standard intermittent RRT for hemodynamically unstable patients
Use CRRT rather than intermittent RRT for AKI patients with acute brain injury or other causes of increased intracranial pressure or generalized brain edema
Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

J Am Coll Cardiol 2008521527-1539
Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

RA) is taken as evidence of high RA pressure in normal patients
Many conditions that can result in an elevated JVP eg RV failure TR or TS pericardial effusion or constrictive pericarditis SVC obstruction Volume overload

Am J Med198783(5)905-8
This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients
RA distance to be 8 cm 97 cm and 98 cm at 30 45 and 60 degrees elevation respectively There is considerable inter-subject variability with dependent variables including age smoking status and AP chest diameter

None of the above criteria for the diagnosis of prerenal disease may be present in a patient with underlying
renal disease
No recent diuretics
In the absence of hemorrhagic shock use isotonic crystalloids rather than colloids (albumin or starches) as initial management for expansion of intravascular volume
Use of vasopressors in conjunction with fluids in patients with vasomotor shock
Use protocol-based management of hemodynamic and oxygenation parameters to prevent development or worsening of AKI in high-risk patients in the perioperative setting or in patients with septic shock

Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Use continuous and intermittent RRT as complementary therapies in AKI patients
Use CRRT rather than standard intermittent RRT for hemodynamically unstable patients
Use CRRT rather than intermittent RRT for AKI patients with acute brain injury or other causes of increased intracranial pressure or generalized brain edema
Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

Use hemodynamic monitoring when possible to help with the management of fluid balance in patients with HRS
Resuscitate patients with HRS type 1 with albumin (initially 1 g of albuminkg for two days up to a maximum of 100 gday followed by 20 to 40 gday) in combination with a vasoconstrictor preferentially terlipressin
RRT should be avoided in HRS type 1 patients unless there is either an acute reversible component or a plan for liver transplantation

Skin turgor No diagnostic value
Physiological Response to fluid challenge Changes in physiological parameters eg MAP HR
CVP after rapid administration of intravenous fluid over a short time
No data on the optimum technique or its diagnostic reliability
Physiological Response to Passive Leg raising Moving the patient from a semi-recumbent position
to a supine position with passive elevation of the legs to 45ordm above the horizontal
Maximal response is seen within 30-60s Descending aortic blood flow of ge10 or
echocardiographic subaortic flow of ge12 ---- fluid responsiveness
Utility of PLR outside the critical care environment is questionable
Clinical Assessment of Volume Status
AKI a competency network Academy of Medical Royal College 2011
JVP Indication of the pressure in the right atrium
NOT a direct measure of volume A measurement of gt3 cm from sternal angle (gt8 cm from
RA) is taken as evidence of high RA pressure in normal patients
Many conditions that can result in an elevated JVP eg RV failure TR or TS pericardial effusion or constrictive pericarditis SVC obstruction Volume overload
J Gen Intern Med 200217(11)852-6Chest 2008134(1)172-8

This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients
RA distance to be 8 cm 97 cm and 98 cm at 30 45 and 60 degrees elevation respectively There is considerable inter-subject variability with dependent variables including age smoking status and AP chest diameter

Differentiating Prerenal vs Intrinsic Renal
FENa () = UNa x SCr x 100
SNa x UCr
FEUrea () = Uurea x SCr x 100
BUN x UCr
None of the above criteria for the diagnosis of prerenal disease may be present in a patient with underlying
renal disease
No recent diuretics
In the absence of hemorrhagic shock use isotonic crystalloids rather than colloids (albumin or starches) as initial management for expansion of intravascular volume
Use of vasopressors in conjunction with fluids in patients with vasomotor shock
Use protocol-based management of hemodynamic and oxygenation parameters to prevent development or worsening of AKI in high-risk patients in the perioperative setting or in patients with septic shock

Provide nutrition preferentially via enteral route in patients with AKI
Administer protein of 08ndash10 gkgd in noncatabolic AKI patients without need
for dialysis 10ndash15 gkgd in patients with AKI on RRT up to 17 gkgd in patients on CRRT and in
hypercatabolic patients

Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Use continuous and intermittent RRT as complementary therapies in AKI patients
Use CRRT rather than standard intermittent RRT for hemodynamically unstable patients
Use CRRT rather than intermittent RRT for AKI patients with acute brain injury or other causes of increased intracranial pressure or generalized brain edema
Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

J Am Coll Cardiol 2008521527-1539
Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

JVP Indication of the pressure in the right atrium
NOT a direct measure of volume A measurement of gt3 cm from sternal angle (gt8 cm from
RA) is taken as evidence of high RA pressure in normal patients
Many conditions that can result in an elevated JVP eg RV failure TR or TS pericardial effusion or constrictive pericarditis SVC obstruction Volume overload
J Gen Intern Med 200217(11)852-6Chest 2008134(1)172-8
Am J Med198783(5)905-8
This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients
RA distance to be 8 cm 97 cm and 98 cm at 30 45 and 60 degrees elevation respectively There is considerable inter-subject variability with dependent variables including age smoking status and AP chest diameter

No recent diuretics
In the absence of hemorrhagic shock use isotonic crystalloids rather than colloids (albumin or starches) as initial management for expansion of intravascular volume
Use of vasopressors in conjunction with fluids in patients with vasomotor shock
Use protocol-based management of hemodynamic and oxygenation parameters to prevent development or worsening of AKI in high-risk patients in the perioperative setting or in patients with septic shock

Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Use CRRT rather than intermittent RRT for AKI patients with acute brain injury or other causes of increased intracranial pressure or generalized brain edema
Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

J Am Coll Cardiol 2008521527-1539
Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen

Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

Skin turgor No diagnostic value
Physiological Response to fluid challenge Changes in physiological parameters eg MAP HR
CVP after rapid administration of intravenous fluid over a short time
No data on the optimum technique or its diagnostic reliability
Physiological Response to Passive Leg raising Moving the patient from a semi-recumbent position
to a supine position with passive elevation of the legs to 45ordm above the horizontal
Maximal response is seen within 30-60s Descending aortic blood flow of ge10 or
echocardiographic subaortic flow of ge12 ---- fluid responsiveness
Utility of PLR outside the critical care environment is questionable
Clinical Assessment of Volume Status
AKI a competency network Academy of Medical Royal College 2011
JVP Indication of the pressure in the right atrium
NOT a direct measure of volume A measurement of gt3 cm from sternal angle (gt8 cm from
RA) is taken as evidence of high RA pressure in normal patients
Many conditions that can result in an elevated JVP eg RV failure TR or TS pericardial effusion or constrictive pericarditis SVC obstruction Volume overload
J Gen Intern Med 200217(11)852-6Chest 2008134(1)172-8
Am J Med198783(5)905-8
This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients
RA distance to be 8 cm 97 cm and 98 cm at 30 45 and 60 degrees elevation respectively There is considerable inter-subject variability with dependent variables including age smoking status and AP chest diameter

Differentiating Prerenal vs Intrinsic Renal
FENa () = UNa x SCr x 100
SNa x UCr
FEUrea () = Uurea x SCr x 100
BUN x UCr
None of the above criteria for the diagnosis of prerenal disease may be present in a patient with underlying
renal disease
No recent diuretics
In the absence of hemorrhagic shock use isotonic crystalloids rather than colloids (albumin or starches) as initial management for expansion of intravascular volume
Use of vasopressors in conjunction with fluids in patients with vasomotor shock
Use protocol-based management of hemodynamic and oxygenation parameters to prevent development or worsening of AKI in high-risk patients in the perioperative setting or in patients with septic shock

Provide nutrition preferentially via enteral route in patients with AKI
Administer protein of 08ndash10 gkgd in noncatabolic AKI patients without need
for dialysis 10ndash15 gkgd in patients with AKI on RRT up to 17 gkgd in patients on CRRT and in
hypercatabolic patients

Effect of Low-dose Dopamine on Need for RRT
Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Use continuous and intermittent RRT as complementary therapies in AKI patients
Use CRRT rather than standard intermittent RRT for hemodynamically unstable patients
Use CRRT rather than intermittent RRT for AKI patients with acute brain injury or other causes of increased intracranial pressure or generalized brain edema
Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

Cardiorenal Syndrome
J Am Coll Cardiol 2008521527-1539
Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

NOT a direct measure of volume A measurement of gt3 cm from sternal angle (gt8 cm from
RA) is taken as evidence of high RA pressure in normal patients
Many conditions that can result in an elevated JVP eg RV failure TR or TS pericardial effusion or constrictive pericarditis SVC obstruction Volume overload

Am J Med198783(5)905-8
This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients
RA distance to be 8 cm 97 cm and 98 cm at 30 45 and 60 degrees elevation respectively There is considerable inter-subject variability with dependent variables including age smoking status and AP chest diameter

No recent diuretics
In the absence of hemorrhagic shock use isotonic crystalloids rather than colloids (albumin or starches) as initial management for expansion of intravascular volume
Use of vasopressors in conjunction with fluids in patients with vasomotor shock
Use protocol-based management of hemodynamic and oxygenation parameters to prevent development or worsening of AKI in high-risk patients in the perioperative setting or in patients with septic shock

Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Use CRRT rather than intermittent RRT for AKI patients with acute brain injury or other causes of increased intracranial pressure or generalized brain edema
Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

J Am Coll Cardiol 2008521527-1539
Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough

A 24 year old wakes up in a bathtub of ice water Scrawled on the bathroom mirror in blood is a message that both of her kidneys were removed and sold On exam she has bilateral nephrectomy scars and an ultrasound confirms absence of both kidneys She has been anuric since a foley was placed 14 hours ago her creatinine is 18
A 62 year old star has arthritis and HT She presents to her primary care doctor with symptoms of fatigue since starting ramipril for her blood pressure Her medications include ibuprofen 800 mg tid HCTZ 25 mg qd simvastatin 40 mg qd and ramipril 10 mg qd Her labs show a Cr of 32 (baseline 12) K of 66 She urinated a ldquonormal amountrdquo prior to coming to the office
A 57 year old british comedian is admitted for decompensated heart failure His baseline creatinine is 14 On admission his creatinine is 22 He is given furosemide and responds well His oxygen requirement decreases most of his edema improves but his creatinine has gone up to 32 His urine output in the last 8 hours is 460 mL

Skin turgor No diagnostic value
Physiological Response to fluid challenge Changes in physiological parameters eg MAP HR
CVP after rapid administration of intravenous fluid over a short time
No data on the optimum technique or its diagnostic reliability
Physiological Response to Passive Leg raising Moving the patient from a semi-recumbent position
to a supine position with passive elevation of the legs to 45ordm above the horizontal
Maximal response is seen within 30-60s Descending aortic blood flow of ge10 or
echocardiographic subaortic flow of ge12 ---- fluid responsiveness
Utility of PLR outside the critical care environment is questionable
Clinical Assessment of Volume Status
AKI a competency network Academy of Medical Royal College 2011
JVP Indication of the pressure in the right atrium
NOT a direct measure of volume A measurement of gt3 cm from sternal angle (gt8 cm from
RA) is taken as evidence of high RA pressure in normal patients
Many conditions that can result in an elevated JVP eg RV failure TR or TS pericardial effusion or constrictive pericarditis SVC obstruction Volume overload
J Gen Intern Med 200217(11)852-6Chest 2008134(1)172-8
Am J Med198783(5)905-8
This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients
RA distance to be 8 cm 97 cm and 98 cm at 30 45 and 60 degrees elevation respectively There is considerable inter-subject variability with dependent variables including age smoking status and AP chest diameter

Differentiating Prerenal vs Intrinsic Renal
FENa () = UNa x SCr x 100
SNa x UCr
FEUrea () = Uurea x SCr x 100
BUN x UCr
None of the above criteria for the diagnosis of prerenal disease may be present in a patient with underlying
renal disease
No recent diuretics
In the absence of hemorrhagic shock use isotonic crystalloids rather than colloids (albumin or starches) as initial management for expansion of intravascular volume
Use of vasopressors in conjunction with fluids in patients with vasomotor shock
Use protocol-based management of hemodynamic and oxygenation parameters to prevent development or worsening of AKI in high-risk patients in the perioperative setting or in patients with septic shock

Insulin therapy targeting plasma glucose 110ndash149 mgdl in critically ill patients
Achieve a total energy intake of 20ndash30 kcalkgd in patients with any stage of AKI
Avoid restriction of protein intake with the aim of preventing or delaying initiation of RRT
Provide nutrition preferentially via enteral route in patients with AKI
Administer protein of 08ndash10 gkgd in noncatabolic AKI patients without need
for dialysis 10ndash15 gkgd in patients with AKI on RRT up to 17 gkgd in patients on CRRT and in
hypercatabolic patients
Glycemic Control and Nutritional Support

Do NOT use diuretics to prevent AKI Do NOT use diuretics to treat AKI except in the management
of volume overload High dose furosemide (gt1 gday) may cause ototoxicity Continuous infusion of 05 mgkghr was not associated with

Effect of Low-dose Dopamine on Need for RRT
Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Use continuous and intermittent RRT as complementary therapies in AKI patients
Use CRRT rather than standard intermittent RRT for hemodynamically unstable patients
Use CRRT rather than intermittent RRT for AKI patients with acute brain injury or other causes of increased intracranial pressure or generalized brain edema
Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

Cardiorenal Syndrome
J Am Coll Cardiol 2008521527-1539
Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

Am J Med198783(5)905-8
This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients
RA distance to be 8 cm 97 cm and 98 cm at 30 45 and 60 degrees elevation respectively There is considerable inter-subject variability with dependent variables including age smoking status and AP chest diameter

In the absence of hemorrhagic shock use isotonic crystalloids rather than colloids (albumin or starches) as initial management for expansion of intravascular volume
Use of vasopressors in conjunction with fluids in patients with vasomotor shock
Use protocol-based management of hemodynamic and oxygenation parameters to prevent development or worsening of AKI in high-risk patients in the perioperative setting or in patients with septic shock

Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Use CRRT rather than intermittent RRT for AKI patients with acute brain injury or other causes of increased intracranial pressure or generalized brain edema
Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

Use hemodynamic monitoring when possible to help with the management of fluid balance in patients with HRS
Resuscitate patients with HRS type 1 with albumin (initially 1 g of albuminkg for two days up to a maximum of 100 gday followed by 20 to 40 gday) in combination with a vasoconstrictor preferentially terlipressin
RRT should be avoided in HRS type 1 patients unless there is either an acute reversible component or a plan for liver transplantation

A 24 year old wakes up in a bathtub of ice water Scrawled on the bathroom mirror in blood is a message that both of her kidneys were removed and sold On exam she has bilateral nephrectomy scars and an ultrasound confirms absence of both kidneys She has been anuric since a foley was placed 14 hours ago her creatinine is 18
A 62 year old star has arthritis and HT She presents to her primary care doctor with symptoms of fatigue since starting ramipril for her blood pressure Her medications include ibuprofen 800 mg tid HCTZ 25 mg qd simvastatin 40 mg qd and ramipril 10 mg qd Her labs show a Cr of 32 (baseline 12) K of 66 She urinated a ldquonormal amountrdquo prior to coming to the office
A 57 year old british comedian is admitted for decompensated heart failure His baseline creatinine is 14 On admission his creatinine is 22 He is given furosemide and responds well His oxygen requirement decreases most of his edema improves but his creatinine has gone up to 32 His urine output in the last 8 hours is 460 mL

Skin turgor No diagnostic value
Physiological Response to fluid challenge Changes in physiological parameters eg MAP HR
CVP after rapid administration of intravenous fluid over a short time
No data on the optimum technique or its diagnostic reliability
Physiological Response to Passive Leg raising Moving the patient from a semi-recumbent position
to a supine position with passive elevation of the legs to 45ordm above the horizontal
Maximal response is seen within 30-60s Descending aortic blood flow of ge10 or
echocardiographic subaortic flow of ge12 ---- fluid responsiveness
Utility of PLR outside the critical care environment is questionable
Clinical Assessment of Volume Status
AKI a competency network Academy of Medical Royal College 2011
JVP Indication of the pressure in the right atrium
NOT a direct measure of volume A measurement of gt3 cm from sternal angle (gt8 cm from
RA) is taken as evidence of high RA pressure in normal patients
Many conditions that can result in an elevated JVP eg RV failure TR or TS pericardial effusion or constrictive pericarditis SVC obstruction Volume overload
J Gen Intern Med 200217(11)852-6Chest 2008134(1)172-8
Am J Med198783(5)905-8
This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients
RA distance to be 8 cm 97 cm and 98 cm at 30 45 and 60 degrees elevation respectively There is considerable inter-subject variability with dependent variables including age smoking status and AP chest diameter

In the absence of hemorrhagic shock use isotonic crystalloids rather than colloids (albumin or starches) as initial management for expansion of intravascular volume
Use of vasopressors in conjunction with fluids in patients with vasomotor shock
Use protocol-based management of hemodynamic and oxygenation parameters to prevent development or worsening of AKI in high-risk patients in the perioperative setting or in patients with septic shock

Achieve a total energy intake of 20ndash30 kcalkgd in patients with any stage of AKI
Avoid restriction of protein intake with the aim of preventing or delaying initiation of RRT
Provide nutrition preferentially via enteral route in patients with AKI
Administer protein of 08ndash10 gkgd in noncatabolic AKI patients without need
for dialysis 10ndash15 gkgd in patients with AKI on RRT up to 17 gkgd in patients on CRRT and in
hypercatabolic patients

Effect of Low-dose Dopamine on Need for RRT
Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Use continuous and intermittent RRT as complementary therapies in AKI patients
Use CRRT rather than standard intermittent RRT for hemodynamically unstable patients
Use CRRT rather than intermittent RRT for AKI patients with acute brain injury or other causes of increased intracranial pressure or generalized brain edema
Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

Cardiorenal Syndrome
J Am Coll Cardiol 2008521527-1539
Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients
RA distance to be 8 cm 97 cm and 98 cm at 30 45 and 60 degrees elevation respectively There is considerable inter-subject variability with dependent variables including age smoking status and AP chest diameter

None of the above criteria for the diagnosis of prerenal disease may be present in a patient with underlying
renal disease
No recent diuretics
In the absence of hemorrhagic shock use isotonic crystalloids rather than colloids (albumin or starches) as initial management for expansion of intravascular volume
Use of vasopressors in conjunction with fluids in patients with vasomotor shock
Use protocol-based management of hemodynamic and oxygenation parameters to prevent development or worsening of AKI in high-risk patients in the perioperative setting or in patients with septic shock

Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

JVP Indication of the pressure in the right atrium
NOT a direct measure of volume A measurement of gt3 cm from sternal angle (gt8 cm from
RA) is taken as evidence of high RA pressure in normal patients
Many conditions that can result in an elevated JVP eg RV failure TR or TS pericardial effusion or constrictive pericarditis SVC obstruction Volume overload

Am J Med198783(5)905-8
This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients

Differentiating Prerenal vs Intrinsic Renal
FENa () = UNa x SCr x 100
SNa x UCr
FEUrea () = Uurea x SCr x 100
BUN x UCr
None of the above criteria for the diagnosis of prerenal disease may be present in a patient with underlying
renal disease
No recent diuretics
In the absence of hemorrhagic shock use isotonic crystalloids rather than colloids (albumin or starches) as initial management for expansion of intravascular volume
Use of vasopressors in conjunction with fluids in patients with vasomotor shock
Use protocol-based management of hemodynamic and oxygenation parameters to prevent development or worsening of AKI in high-risk patients in the perioperative setting or in patients with septic shock

Effect of Low-dose Dopamine on Need for RRT
Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Femoral --- CRRT
Use continuous and intermittent RRT as complementary therapies in AKI patients
Use CRRT rather than standard intermittent RRT for hemodynamically unstable patients
Use CRRT rather than intermittent RRT for AKI patients with acute brain injury or other causes of increased intracranial pressure or generalized brain edema
Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

CI-AKI Risk Score Model for PCI
Repeated exposure of CM should be delayed for 48 hr in patients without risk factors for CI-AKI 72 hr in patients with DM or pre-existing chronic renal
dysfunction Stop nephrotoxic medications eg NSAIDs aminoglycosides
amphotericin B high dose loop diuretics acyclovir ACEIARBs can be continued Consider alternative imaging methods in patients at
increased risk Use the lowest possible dose of contrast medium in patients
at risk
Use iso-osmolar or low osmolar iodinated contrast media rather than high-osmolar iodinated contrast media in patients at risk

Cardiorenal Syndrome
J Am Coll Cardiol 2008521527-1539
Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

Use hemodynamic monitoring when possible to help with the management of fluid balance in patients with HRS
Resuscitate patients with HRS type 1 with albumin (initially 1 g of albuminkg for two days up to a maximum of 100 gday followed by 20 to 40 gday) in combination with a vasoconstrictor preferentially terlipressin
RRT should be avoided in HRS type 1 patients unless there is either an acute reversible component or a plan for liver transplantation

Physiological Response to fluid challenge Changes in physiological parameters eg MAP HR
CVP after rapid administration of intravenous fluid over a short time
No data on the optimum technique or its diagnostic reliability
Physiological Response to Passive Leg raising Moving the patient from a semi-recumbent position
to a supine position with passive elevation of the legs to 45ordm above the horizontal
Maximal response is seen within 30-60s Descending aortic blood flow of ge10 or
echocardiographic subaortic flow of ge12 ---- fluid responsiveness
Utility of PLR outside the critical care environment is questionable
Clinical Assessment of Volume Status
AKI a competency network Academy of Medical Royal College 2011
JVP Indication of the pressure in the right atrium
NOT a direct measure of volume A measurement of gt3 cm from sternal angle (gt8 cm from
RA) is taken as evidence of high RA pressure in normal patients
Many conditions that can result in an elevated JVP eg RV failure TR or TS pericardial effusion or constrictive pericarditis SVC obstruction Volume overload

This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients
RA distance to be 8 cm 97 cm and 98 cm at 30 45 and 60 degrees elevation respectively There is considerable inter-subject variability with dependent variables including age smoking status and AP chest diameter

Differentiating Prerenal vs Intrinsic Renal
FENa () = UNa x SCr x 100
SNa x UCr
FEUrea () = Uurea x SCr x 100
BUN x UCr
None of the above criteria for the diagnosis of prerenal disease may be present in a patient with underlying
renal disease
No recent diuretics
In the absence of hemorrhagic shock use isotonic crystalloids rather than colloids (albumin or starches) as initial management for expansion of intravascular volume
Use of vasopressors in conjunction with fluids in patients with vasomotor shock
Use protocol-based management of hemodynamic and oxygenation parameters to prevent development or worsening of AKI in high-risk patients in the perioperative setting or in patients with septic shock

Effect of Low-dose Dopamine on Need for RRT
Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Use continuous and intermittent RRT as complementary therapies in AKI patients
Use CRRT rather than standard intermittent RRT for hemodynamically unstable patients
Use CRRT rather than intermittent RRT for AKI patients with acute brain injury or other causes of increased intracranial pressure or generalized brain edema
Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

J Am Coll Cardiol 2008521527-1539
Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

JVP Indication of the pressure in the right atrium
NOT a direct measure of volume A measurement of gt3 cm from sternal angle (gt8 cm from
RA) is taken as evidence of high RA pressure in normal patients
Many conditions that can result in an elevated JVP eg RV failure TR or TS pericardial effusion or constrictive pericarditis SVC obstruction Volume overload

Am J Med198783(5)905-8
This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients
RA distance to be 8 cm 97 cm and 98 cm at 30 45 and 60 degrees elevation respectively There is considerable inter-subject variability with dependent variables including age smoking status and AP chest diameter

No recent diuretics
In the absence of hemorrhagic shock use isotonic crystalloids rather than colloids (albumin or starches) as initial management for expansion of intravascular volume
Use of vasopressors in conjunction with fluids in patients with vasomotor shock
Use protocol-based management of hemodynamic and oxygenation parameters to prevent development or worsening of AKI in high-risk patients in the perioperative setting or in patients with septic shock

Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Use CRRT rather than intermittent RRT for AKI patients with acute brain injury or other causes of increased intracranial pressure or generalized brain edema
Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

J Am Coll Cardiol 2008521527-1539
Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate

Physiological Response to fluid challenge Changes in physiological parameters eg MAP HR
CVP after rapid administration of intravenous fluid over a short time
No data on the optimum technique or its diagnostic reliability
Physiological Response to Passive Leg raising Moving the patient from a semi-recumbent position
to a supine position with passive elevation of the legs to 45ordm above the horizontal
Maximal response is seen within 30-60s Descending aortic blood flow of ge10 or
echocardiographic subaortic flow of ge12 ---- fluid responsiveness
Utility of PLR outside the critical care environment is questionable
Clinical Assessment of Volume Status
AKI a competency network Academy of Medical Royal College 2011
JVP Indication of the pressure in the right atrium
NOT a direct measure of volume A measurement of gt3 cm from sternal angle (gt8 cm from
RA) is taken as evidence of high RA pressure in normal patients
Many conditions that can result in an elevated JVP eg RV failure TR or TS pericardial effusion or constrictive pericarditis SVC obstruction Volume overload
J Gen Intern Med 200217(11)852-6Chest 2008134(1)172-8
Am J Med198783(5)905-8
This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients
RA distance to be 8 cm 97 cm and 98 cm at 30 45 and 60 degrees elevation respectively There is considerable inter-subject variability with dependent variables including age smoking status and AP chest diameter

Differentiating Prerenal vs Intrinsic Renal
FENa () = UNa x SCr x 100
SNa x UCr
FEUrea () = Uurea x SCr x 100
BUN x UCr
None of the above criteria for the diagnosis of prerenal disease may be present in a patient with underlying
renal disease
No recent diuretics
In the absence of hemorrhagic shock use isotonic crystalloids rather than colloids (albumin or starches) as initial management for expansion of intravascular volume
Use of vasopressors in conjunction with fluids in patients with vasomotor shock
Use protocol-based management of hemodynamic and oxygenation parameters to prevent development or worsening of AKI in high-risk patients in the perioperative setting or in patients with septic shock

Avoid restriction of protein intake with the aim of preventing or delaying initiation of RRT
Provide nutrition preferentially via enteral route in patients with AKI
Administer protein of 08ndash10 gkgd in noncatabolic AKI patients without need
for dialysis 10ndash15 gkgd in patients with AKI on RRT up to 17 gkgd in patients on CRRT and in
hypercatabolic patients
Glycemic Control and Nutritional Support
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Do NOT use diuretics to prevent AKI Do NOT use diuretics to treat AKI except in the management
of volume overload High dose furosemide (gt1 gday) may cause ototoxicity Continuous infusion of 05 mgkghr was not associated with
ototoxicity Do NOT use low dose dopamine (1ndash3 mgkgmin) to prevent

Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Use continuous and intermittent RRT as complementary therapies in AKI patients
Use CRRT rather than standard intermittent RRT for hemodynamically unstable patients
Use CRRT rather than intermittent RRT for AKI patients with acute brain injury or other causes of increased intracranial pressure or generalized brain edema
Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

J Am Coll Cardiol 2008521527-1539
Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

Skin turgor No diagnostic value
Physiological Response to fluid challenge Changes in physiological parameters eg MAP HR
CVP after rapid administration of intravenous fluid over a short time
No data on the optimum technique or its diagnostic reliability
Physiological Response to Passive Leg raising Moving the patient from a semi-recumbent position
to a supine position with passive elevation of the legs to 45ordm above the horizontal
Maximal response is seen within 30-60s Descending aortic blood flow of ge10 or
echocardiographic subaortic flow of ge12 ---- fluid responsiveness
Utility of PLR outside the critical care environment is questionable
Clinical Assessment of Volume Status
AKI a competency network Academy of Medical Royal College 2011
JVP Indication of the pressure in the right atrium
NOT a direct measure of volume A measurement of gt3 cm from sternal angle (gt8 cm from
RA) is taken as evidence of high RA pressure in normal patients
Many conditions that can result in an elevated JVP eg RV failure TR or TS pericardial effusion or constrictive pericarditis SVC obstruction Volume overload
J Gen Intern Med 200217(11)852-6Chest 2008134(1)172-8
Am J Med198783(5)905-8
This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients
RA distance to be 8 cm 97 cm and 98 cm at 30 45 and 60 degrees elevation respectively There is considerable inter-subject variability with dependent variables including age smoking status and AP chest diameter

Differentiating Prerenal vs Intrinsic Renal
FENa () = UNa x SCr x 100
SNa x UCr
FEUrea () = Uurea x SCr x 100
BUN x UCr
None of the above criteria for the diagnosis of prerenal disease may be present in a patient with underlying
renal disease
No recent diuretics
In the absence of hemorrhagic shock use isotonic crystalloids rather than colloids (albumin or starches) as initial management for expansion of intravascular volume
Use of vasopressors in conjunction with fluids in patients with vasomotor shock
Use protocol-based management of hemodynamic and oxygenation parameters to prevent development or worsening of AKI in high-risk patients in the perioperative setting or in patients with septic shock

Effect of Low-dose Dopamine on Need for RRT
Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Use continuous and intermittent RRT as complementary therapies in AKI patients
Use CRRT rather than standard intermittent RRT for hemodynamically unstable patients
Use CRRT rather than intermittent RRT for AKI patients with acute brain injury or other causes of increased intracranial pressure or generalized brain edema
Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

Am J Med198783(5)905-8
This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients
RA distance to be 8 cm 97 cm and 98 cm at 30 45 and 60 degrees elevation respectively There is considerable inter-subject variability with dependent variables including age smoking status and AP chest diameter

No recent diuretics
In the absence of hemorrhagic shock use isotonic crystalloids rather than colloids (albumin or starches) as initial management for expansion of intravascular volume
Use of vasopressors in conjunction with fluids in patients with vasomotor shock
Use protocol-based management of hemodynamic and oxygenation parameters to prevent development or worsening of AKI in high-risk patients in the perioperative setting or in patients with septic shock

Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Use CRRT rather than intermittent RRT for AKI patients with acute brain injury or other causes of increased intracranial pressure or generalized brain edema
Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

No data on the optimum technique or its diagnostic reliability
Physiological Response to Passive Leg raising Moving the patient from a semi-recumbent position
to a supine position with passive elevation of the legs to 45ordm above the horizontal
Maximal response is seen within 30-60s Descending aortic blood flow of ge10 or
echocardiographic subaortic flow of ge12 ---- fluid responsiveness

Clinical Assessment of Volume Status
AKI a competency network Academy of Medical Royal College 2011
JVP Indication of the pressure in the right atrium
NOT a direct measure of volume A measurement of gt3 cm from sternal angle (gt8 cm from
RA) is taken as evidence of high RA pressure in normal patients
Many conditions that can result in an elevated JVP eg RV failure TR or TS pericardial effusion or constrictive pericarditis SVC obstruction Volume overload
J Gen Intern Med 200217(11)852-6Chest 2008134(1)172-8
Am J Med198783(5)905-8
This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients
RA distance to be 8 cm 97 cm and 98 cm at 30 45 and 60 degrees elevation respectively There is considerable inter-subject variability with dependent variables including age smoking status and AP chest diameter

Differentiating Prerenal vs Intrinsic Renal
FENa () = UNa x SCr x 100
SNa x UCr
FEUrea () = Uurea x SCr x 100
BUN x UCr
None of the above criteria for the diagnosis of prerenal disease may be present in a patient with underlying
renal disease
No recent diuretics
In the absence of hemorrhagic shock use isotonic crystalloids rather than colloids (albumin or starches) as initial management for expansion of intravascular volume
Use of vasopressors in conjunction with fluids in patients with vasomotor shock
Use protocol-based management of hemodynamic and oxygenation parameters to prevent development or worsening of AKI in high-risk patients in the perioperative setting or in patients with septic shock

Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Use continuous and intermittent RRT as complementary therapies in AKI patients
Use CRRT rather than standard intermittent RRT for hemodynamically unstable patients
Use CRRT rather than intermittent RRT for AKI patients with acute brain injury or other causes of increased intracranial pressure or generalized brain edema
Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

J Am Coll Cardiol 2008521527-1539
Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

Skin turgor No diagnostic value
Physiological Response to fluid challenge Changes in physiological parameters eg MAP HR
CVP after rapid administration of intravenous fluid over a short time
No data on the optimum technique or its diagnostic reliability
Physiological Response to Passive Leg raising Moving the patient from a semi-recumbent position
to a supine position with passive elevation of the legs to 45ordm above the horizontal
Maximal response is seen within 30-60s Descending aortic blood flow of ge10 or
echocardiographic subaortic flow of ge12 ---- fluid responsiveness
Utility of PLR outside the critical care environment is questionable
Clinical Assessment of Volume Status
AKI a competency network Academy of Medical Royal College 2011
JVP Indication of the pressure in the right atrium
NOT a direct measure of volume A measurement of gt3 cm from sternal angle (gt8 cm from
RA) is taken as evidence of high RA pressure in normal patients
Many conditions that can result in an elevated JVP eg RV failure TR or TS pericardial effusion or constrictive pericarditis SVC obstruction Volume overload

Am J Med198783(5)905-8
This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients
RA distance to be 8 cm 97 cm and 98 cm at 30 45 and 60 degrees elevation respectively There is considerable inter-subject variability with dependent variables including age smoking status and AP chest diameter

Differentiating Prerenal vs Intrinsic Renal
FENa () = UNa x SCr x 100
SNa x UCr
FEUrea () = Uurea x SCr x 100
BUN x UCr
None of the above criteria for the diagnosis of prerenal disease may be present in a patient with underlying
renal disease
No recent diuretics
In the absence of hemorrhagic shock use isotonic crystalloids rather than colloids (albumin or starches) as initial management for expansion of intravascular volume
Use of vasopressors in conjunction with fluids in patients with vasomotor shock
Use protocol-based management of hemodynamic and oxygenation parameters to prevent development or worsening of AKI in high-risk patients in the perioperative setting or in patients with septic shock

Effect of Low-dose Dopamine on Need for RRT
Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Use continuous and intermittent RRT as complementary therapies in AKI patients
Use CRRT rather than standard intermittent RRT for hemodynamically unstable patients
Use CRRT rather than intermittent RRT for AKI patients with acute brain injury or other causes of increased intracranial pressure or generalized brain edema
Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

J Am Coll Cardiol 2008521527-1539
Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

JVP Indication of the pressure in the right atrium
NOT a direct measure of volume A measurement of gt3 cm from sternal angle (gt8 cm from
RA) is taken as evidence of high RA pressure in normal patients
Many conditions that can result in an elevated JVP eg RV failure TR or TS pericardial effusion or constrictive pericarditis SVC obstruction Volume overload

Am J Med198783(5)905-8
This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients
RA distance to be 8 cm 97 cm and 98 cm at 30 45 and 60 degrees elevation respectively There is considerable inter-subject variability with dependent variables including age smoking status and AP chest diameter

No recent diuretics
In the absence of hemorrhagic shock use isotonic crystalloids rather than colloids (albumin or starches) as initial management for expansion of intravascular volume
Use of vasopressors in conjunction with fluids in patients with vasomotor shock
Use protocol-based management of hemodynamic and oxygenation parameters to prevent development or worsening of AKI in high-risk patients in the perioperative setting or in patients with septic shock

Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Use CRRT rather than intermittent RRT for AKI patients with acute brain injury or other causes of increased intracranial pressure or generalized brain edema
Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

J Am Coll Cardiol 2008521527-1539
Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate

No data on the optimum technique or its diagnostic reliability
Physiological Response to Passive Leg raising Moving the patient from a semi-recumbent position
to a supine position with passive elevation of the legs to 45ordm above the horizontal
Maximal response is seen within 30-60s Descending aortic blood flow of ge10 or
echocardiographic subaortic flow of ge12 ---- fluid responsiveness

Clinical Assessment of Volume Status
AKI a competency network Academy of Medical Royal College 2011
JVP Indication of the pressure in the right atrium
NOT a direct measure of volume A measurement of gt3 cm from sternal angle (gt8 cm from
RA) is taken as evidence of high RA pressure in normal patients
Many conditions that can result in an elevated JVP eg RV failure TR or TS pericardial effusion or constrictive pericarditis SVC obstruction Volume overload
J Gen Intern Med 200217(11)852-6Chest 2008134(1)172-8
Am J Med198783(5)905-8
This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients
RA distance to be 8 cm 97 cm and 98 cm at 30 45 and 60 degrees elevation respectively There is considerable inter-subject variability with dependent variables including age smoking status and AP chest diameter

Differentiating Prerenal vs Intrinsic Renal
FENa () = UNa x SCr x 100
SNa x UCr
FEUrea () = Uurea x SCr x 100
BUN x UCr
None of the above criteria for the diagnosis of prerenal disease may be present in a patient with underlying
renal disease
No recent diuretics
In the absence of hemorrhagic shock use isotonic crystalloids rather than colloids (albumin or starches) as initial management for expansion of intravascular volume
Use of vasopressors in conjunction with fluids in patients with vasomotor shock
Use protocol-based management of hemodynamic and oxygenation parameters to prevent development or worsening of AKI in high-risk patients in the perioperative setting or in patients with septic shock

Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed

Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Use continuous and intermittent RRT as complementary therapies in AKI patients
Use CRRT rather than standard intermittent RRT for hemodynamically unstable patients
Use CRRT rather than intermittent RRT for AKI patients with acute brain injury or other causes of increased intracranial pressure or generalized brain edema
Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

Cardiorenal Syndrome
J Am Coll Cardiol 2008521527-1539
Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

to a supine position with passive elevation of the legs to 45ordm above the horizontal
Maximal response is seen within 30-60s Descending aortic blood flow of ge10 or
echocardiographic subaortic flow of ge12 ---- fluid responsiveness
Utility of PLR outside the critical care environment is questionable
Clinical Assessment of Volume Status
AKI a competency network Academy of Medical Royal College 2011
JVP Indication of the pressure in the right atrium
NOT a direct measure of volume A measurement of gt3 cm from sternal angle (gt8 cm from
RA) is taken as evidence of high RA pressure in normal patients
Many conditions that can result in an elevated JVP eg RV failure TR or TS pericardial effusion or constrictive pericarditis SVC obstruction Volume overload
J Gen Intern Med 200217(11)852-6Chest 2008134(1)172-8
Am J Med198783(5)905-8
This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients
RA distance to be 8 cm 97 cm and 98 cm at 30 45 and 60 degrees elevation respectively There is considerable inter-subject variability with dependent variables including age smoking status and AP chest diameter

Differentiating Prerenal vs Intrinsic Renal
FENa () = UNa x SCr x 100
SNa x UCr
FEUrea () = Uurea x SCr x 100
BUN x UCr
None of the above criteria for the diagnosis of prerenal disease may be present in a patient with underlying
renal disease
No recent diuretics
In the absence of hemorrhagic shock use isotonic crystalloids rather than colloids (albumin or starches) as initial management for expansion of intravascular volume
Use of vasopressors in conjunction with fluids in patients with vasomotor shock
Use protocol-based management of hemodynamic and oxygenation parameters to prevent development or worsening of AKI in high-risk patients in the perioperative setting or in patients with septic shock

Effect of Low-dose Dopamine on Need for RRT
Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Use continuous and intermittent RRT as complementary therapies in AKI patients
Use CRRT rather than standard intermittent RRT for hemodynamically unstable patients
Use CRRT rather than intermittent RRT for AKI patients with acute brain injury or other causes of increased intracranial pressure or generalized brain edema
Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

Cardiorenal Syndrome
J Am Coll Cardiol 2008521527-1539
Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients
RA distance to be 8 cm 97 cm and 98 cm at 30 45 and 60 degrees elevation respectively There is considerable inter-subject variability with dependent variables including age smoking status and AP chest diameter

None of the above criteria for the diagnosis of prerenal disease may be present in a patient with underlying
renal disease
No recent diuretics
In the absence of hemorrhagic shock use isotonic crystalloids rather than colloids (albumin or starches) as initial management for expansion of intravascular volume
Use of vasopressors in conjunction with fluids in patients with vasomotor shock
Use protocol-based management of hemodynamic and oxygenation parameters to prevent development or worsening of AKI in high-risk patients in the perioperative setting or in patients with septic shock

Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

JVP Indication of the pressure in the right atrium
NOT a direct measure of volume A measurement of gt3 cm from sternal angle (gt8 cm from
RA) is taken as evidence of high RA pressure in normal patients
Many conditions that can result in an elevated JVP eg RV failure TR or TS pericardial effusion or constrictive pericarditis SVC obstruction Volume overload
J Gen Intern Med 200217(11)852-6Chest 2008134(1)172-8
Am J Med198783(5)905-8
This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients
RA distance to be 8 cm 97 cm and 98 cm at 30 45 and 60 degrees elevation respectively There is considerable inter-subject variability with dependent variables including age smoking status and AP chest diameter

Differentiating Prerenal vs Intrinsic Renal
FENa () = UNa x SCr x 100
SNa x UCr
FEUrea () = Uurea x SCr x 100
BUN x UCr
None of the above criteria for the diagnosis of prerenal disease may be present in a patient with underlying
renal disease
No recent diuretics
In the absence of hemorrhagic shock use isotonic crystalloids rather than colloids (albumin or starches) as initial management for expansion of intravascular volume
Use of vasopressors in conjunction with fluids in patients with vasomotor shock
Use protocol-based management of hemodynamic and oxygenation parameters to prevent development or worsening of AKI in high-risk patients in the perioperative setting or in patients with septic shock

Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Use continuous and intermittent RRT as complementary therapies in AKI patients
Use CRRT rather than standard intermittent RRT for hemodynamically unstable patients
Use CRRT rather than intermittent RRT for AKI patients with acute brain injury or other causes of increased intracranial pressure or generalized brain edema
Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

Type 1 acute decrease in cardiac function leads to acute kidney injury
Type 2 chronic decrease in cardiac function leads to progressive CKD
Type 3 acute kidney injury leads to acute cardiac dysfunction
Type 4 chronic kidney disease leading to decreased cardiac function cardiac hypertrophy andor increased risk of adverse cardiovascular events
Type 5 Systemic condition (eg sepsis) causing both cardiac and renal dysfunction
Cardiorenal Syndrome
J Am Coll Cardiol 2008521527-1539
Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

CVP after rapid administration of intravenous fluid over a short time
No data on the optimum technique or its diagnostic reliability
Physiological Response to Passive Leg raising Moving the patient from a semi-recumbent position
to a supine position with passive elevation of the legs to 45ordm above the horizontal
Maximal response is seen within 30-60s Descending aortic blood flow of ge10 or
echocardiographic subaortic flow of ge12 ---- fluid responsiveness
Utility of PLR outside the critical care environment is questionable
Clinical Assessment of Volume Status
AKI a competency network Academy of Medical Royal College 2011
JVP Indication of the pressure in the right atrium
NOT a direct measure of volume A measurement of gt3 cm from sternal angle (gt8 cm from
RA) is taken as evidence of high RA pressure in normal patients
Many conditions that can result in an elevated JVP eg RV failure TR or TS pericardial effusion or constrictive pericarditis SVC obstruction Volume overload
J Gen Intern Med 200217(11)852-6Chest 2008134(1)172-8
Am J Med198783(5)905-8
This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients
RA distance to be 8 cm 97 cm and 98 cm at 30 45 and 60 degrees elevation respectively There is considerable inter-subject variability with dependent variables including age smoking status and AP chest diameter

Differentiating Prerenal vs Intrinsic Renal
FENa () = UNa x SCr x 100
SNa x UCr
FEUrea () = Uurea x SCr x 100
BUN x UCr
None of the above criteria for the diagnosis of prerenal disease may be present in a patient with underlying
renal disease
No recent diuretics
In the absence of hemorrhagic shock use isotonic crystalloids rather than colloids (albumin or starches) as initial management for expansion of intravascular volume
Use of vasopressors in conjunction with fluids in patients with vasomotor shock
Use protocol-based management of hemodynamic and oxygenation parameters to prevent development or worsening of AKI in high-risk patients in the perioperative setting or in patients with septic shock

Insulin therapy targeting plasma glucose 110ndash149 mgdl in critically ill patients
Achieve a total energy intake of 20ndash30 kcalkgd in patients with any stage of AKI
Avoid restriction of protein intake with the aim of preventing or delaying initiation of RRT
Provide nutrition preferentially via enteral route in patients with AKI
Administer protein of 08ndash10 gkgd in noncatabolic AKI patients without need
for dialysis 10ndash15 gkgd in patients with AKI on RRT up to 17 gkgd in patients on CRRT and in
hypercatabolic patients

Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Use continuous and intermittent RRT as complementary therapies in AKI patients
Use CRRT rather than standard intermittent RRT for hemodynamically unstable patients
Use CRRT rather than intermittent RRT for AKI patients with acute brain injury or other causes of increased intracranial pressure or generalized brain edema
Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

J Am Coll Cardiol 2008521527-1539
Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

Skin turgor No diagnostic value
Physiological Response to fluid challenge Changes in physiological parameters eg MAP HR
CVP after rapid administration of intravenous fluid over a short time
No data on the optimum technique or its diagnostic reliability
Physiological Response to Passive Leg raising Moving the patient from a semi-recumbent position
to a supine position with passive elevation of the legs to 45ordm above the horizontal
Maximal response is seen within 30-60s Descending aortic blood flow of ge10 or
echocardiographic subaortic flow of ge12 ---- fluid responsiveness
Utility of PLR outside the critical care environment is questionable
Clinical Assessment of Volume Status
AKI a competency network Academy of Medical Royal College 2011
JVP Indication of the pressure in the right atrium
NOT a direct measure of volume A measurement of gt3 cm from sternal angle (gt8 cm from
RA) is taken as evidence of high RA pressure in normal patients
Many conditions that can result in an elevated JVP eg RV failure TR or TS pericardial effusion or constrictive pericarditis SVC obstruction Volume overload

This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients
RA distance to be 8 cm 97 cm and 98 cm at 30 45 and 60 degrees elevation respectively There is considerable inter-subject variability with dependent variables including age smoking status and AP chest diameter

Differentiating Prerenal vs Intrinsic Renal
FENa () = UNa x SCr x 100
SNa x UCr
FEUrea () = Uurea x SCr x 100
BUN x UCr
None of the above criteria for the diagnosis of prerenal disease may be present in a patient with underlying
renal disease
No recent diuretics
In the absence of hemorrhagic shock use isotonic crystalloids rather than colloids (albumin or starches) as initial management for expansion of intravascular volume
Use of vasopressors in conjunction with fluids in patients with vasomotor shock
Use protocol-based management of hemodynamic and oxygenation parameters to prevent development or worsening of AKI in high-risk patients in the perioperative setting or in patients with septic shock

Effect of Low-dose Dopamine on Need for RRT
Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Use continuous and intermittent RRT as complementary therapies in AKI patients
Use CRRT rather than standard intermittent RRT for hemodynamically unstable patients
Use CRRT rather than intermittent RRT for AKI patients with acute brain injury or other causes of increased intracranial pressure or generalized brain edema
Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

J Am Coll Cardiol 2008521527-1539
Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

JVP Indication of the pressure in the right atrium
NOT a direct measure of volume A measurement of gt3 cm from sternal angle (gt8 cm from
RA) is taken as evidence of high RA pressure in normal patients
Many conditions that can result in an elevated JVP eg RV failure TR or TS pericardial effusion or constrictive pericarditis SVC obstruction Volume overload

This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients
RA distance to be 8 cm 97 cm and 98 cm at 30 45 and 60 degrees elevation respectively There is considerable inter-subject variability with dependent variables including age smoking status and AP chest diameter

Differentiating Prerenal vs Intrinsic Renal
FENa () = UNa x SCr x 100
SNa x UCr
FEUrea () = Uurea x SCr x 100
BUN x UCr
None of the above criteria for the diagnosis of prerenal disease may be present in a patient with underlying
renal disease
No recent diuretics
In the absence of hemorrhagic shock use isotonic crystalloids rather than colloids (albumin or starches) as initial management for expansion of intravascular volume
Use of vasopressors in conjunction with fluids in patients with vasomotor shock
Use protocol-based management of hemodynamic and oxygenation parameters to prevent development or worsening of AKI in high-risk patients in the perioperative setting or in patients with septic shock

Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Use continuous and intermittent RRT as complementary therapies in AKI patients
Use CRRT rather than standard intermittent RRT for hemodynamically unstable patients
Use CRRT rather than intermittent RRT for AKI patients with acute brain injury or other causes of increased intracranial pressure or generalized brain edema
Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients
RA distance to be 8 cm 97 cm and 98 cm at 30 45 and 60 degrees elevation respectively There is considerable inter-subject variability with dependent variables including age smoking status and AP chest diameter

In the absence of hemorrhagic shock use isotonic crystalloids rather than colloids (albumin or starches) as initial management for expansion of intravascular volume
Use of vasopressors in conjunction with fluids in patients with vasomotor shock
Use protocol-based management of hemodynamic and oxygenation parameters to prevent development or worsening of AKI in high-risk patients in the perioperative setting or in patients with septic shock

Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Use CRRT rather than intermittent RRT for AKI patients with acute brain injury or other causes of increased intracranial pressure or generalized brain edema
Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

JVP Indication of the pressure in the right atrium
NOT a direct measure of volume A measurement of gt3 cm from sternal angle (gt8 cm from
RA) is taken as evidence of high RA pressure in normal patients
Many conditions that can result in an elevated JVP eg RV failure TR or TS pericardial effusion or constrictive pericarditis SVC obstruction Volume overload
J Gen Intern Med 200217(11)852-6Chest 2008134(1)172-8
Am J Med198783(5)905-8
This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients
RA distance to be 8 cm 97 cm and 98 cm at 30 45 and 60 degrees elevation respectively There is considerable inter-subject variability with dependent variables including age smoking status and AP chest diameter

Differentiating Prerenal vs Intrinsic Renal
FENa () = UNa x SCr x 100
SNa x UCr
FEUrea () = Uurea x SCr x 100
BUN x UCr
None of the above criteria for the diagnosis of prerenal disease may be present in a patient with underlying
renal disease
No recent diuretics
In the absence of hemorrhagic shock use isotonic crystalloids rather than colloids (albumin or starches) as initial management for expansion of intravascular volume
Use of vasopressors in conjunction with fluids in patients with vasomotor shock
Use protocol-based management of hemodynamic and oxygenation parameters to prevent development or worsening of AKI in high-risk patients in the perioperative setting or in patients with septic shock

Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Use continuous and intermittent RRT as complementary therapies in AKI patients
Use CRRT rather than standard intermittent RRT for hemodynamically unstable patients
Use CRRT rather than intermittent RRT for AKI patients with acute brain injury or other causes of increased intracranial pressure or generalized brain edema
Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

Cardiorenal Syndrome
J Am Coll Cardiol 2008521527-1539
Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

JVP Indication of the pressure in the right atrium
NOT a direct measure of volume A measurement of gt3 cm from sternal angle (gt8 cm from
RA) is taken as evidence of high RA pressure in normal patients
Many conditions that can result in an elevated JVP eg RV failure TR or TS pericardial effusion or constrictive pericarditis SVC obstruction Volume overload
J Gen Intern Med 200217(11)852-6Chest 2008134(1)172-8
Am J Med198783(5)905-8
This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients
RA distance to be 8 cm 97 cm and 98 cm at 30 45 and 60 degrees elevation respectively There is considerable inter-subject variability with dependent variables including age smoking status and AP chest diameter

Differentiating Prerenal vs Intrinsic Renal
FENa () = UNa x SCr x 100
SNa x UCr
FEUrea () = Uurea x SCr x 100
BUN x UCr
None of the above criteria for the diagnosis of prerenal disease may be present in a patient with underlying
renal disease
No recent diuretics
In the absence of hemorrhagic shock use isotonic crystalloids rather than colloids (albumin or starches) as initial management for expansion of intravascular volume
Use of vasopressors in conjunction with fluids in patients with vasomotor shock
Use protocol-based management of hemodynamic and oxygenation parameters to prevent development or worsening of AKI in high-risk patients in the perioperative setting or in patients with septic shock

Effect of Low-dose Dopamine on Need for RRT
Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens

Use continuous and intermittent RRT as complementary therapies in AKI patients
Use CRRT rather than standard intermittent RRT for hemodynamically unstable patients
Use CRRT rather than intermittent RRT for AKI patients with acute brain injury or other causes of increased intracranial pressure or generalized brain edema
Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

Cardiorenal Syndrome
J Am Coll Cardiol 2008521527-1539
Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

Clinical Assessment of Volume Status
AKI a competency network Academy of Medical Royal College 2011
JVP Indication of the pressure in the right atrium
NOT a direct measure of volume A measurement of gt3 cm from sternal angle (gt8 cm from
RA) is taken as evidence of high RA pressure in normal patients
Many conditions that can result in an elevated JVP eg RV failure TR or TS pericardial effusion or constrictive pericarditis SVC obstruction Volume overload
J Gen Intern Med 200217(11)852-6Chest 2008134(1)172-8
Am J Med198783(5)905-8
This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients
RA distance to be 8 cm 97 cm and 98 cm at 30 45 and 60 degrees elevation respectively There is considerable inter-subject variability with dependent variables including age smoking status and AP chest diameter

None of the above criteria for the diagnosis of prerenal disease may be present in a patient with underlying
renal disease
No recent diuretics
In the absence of hemorrhagic shock use isotonic crystalloids rather than colloids (albumin or starches) as initial management for expansion of intravascular volume
Use of vasopressors in conjunction with fluids in patients with vasomotor shock
Use protocol-based management of hemodynamic and oxygenation parameters to prevent development or worsening of AKI in high-risk patients in the perioperative setting or in patients with septic shock

Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Use continuous and intermittent RRT as complementary therapies in AKI patients
Use CRRT rather than standard intermittent RRT for hemodynamically unstable patients
Use CRRT rather than intermittent RRT for AKI patients with acute brain injury or other causes of increased intracranial pressure or generalized brain edema
Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

J Am Coll Cardiol 2008521527-1539
Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

JVP Indication of the pressure in the right atrium
NOT a direct measure of volume A measurement of gt3 cm from sternal angle (gt8 cm from
RA) is taken as evidence of high RA pressure in normal patients
Many conditions that can result in an elevated JVP eg RV failure TR or TS pericardial effusion or constrictive pericarditis SVC obstruction Volume overload
J Gen Intern Med 200217(11)852-6Chest 2008134(1)172-8
Am J Med198783(5)905-8
This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients
RA distance to be 8 cm 97 cm and 98 cm at 30 45 and 60 degrees elevation respectively There is considerable inter-subject variability with dependent variables including age smoking status and AP chest diameter

Differentiating Prerenal vs Intrinsic Renal
FENa () = UNa x SCr x 100
SNa x UCr
FEUrea () = Uurea x SCr x 100
BUN x UCr
None of the above criteria for the diagnosis of prerenal disease may be present in a patient with underlying
renal disease
No recent diuretics
In the absence of hemorrhagic shock use isotonic crystalloids rather than colloids (albumin or starches) as initial management for expansion of intravascular volume
Use of vasopressors in conjunction with fluids in patients with vasomotor shock
Use protocol-based management of hemodynamic and oxygenation parameters to prevent development or worsening of AKI in high-risk patients in the perioperative setting or in patients with septic shock

Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Use continuous and intermittent RRT as complementary therapies in AKI patients
Use CRRT rather than standard intermittent RRT for hemodynamically unstable patients
Use CRRT rather than intermittent RRT for AKI patients with acute brain injury or other causes of increased intracranial pressure or generalized brain edema
Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

Cardiorenal Syndrome
J Am Coll Cardiol 2008521527-1539
Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

Physiological Response to fluid challenge Changes in physiological parameters eg MAP HR
CVP after rapid administration of intravenous fluid over a short time
No data on the optimum technique or its diagnostic reliability
Physiological Response to Passive Leg raising Moving the patient from a semi-recumbent position
to a supine position with passive elevation of the legs to 45ordm above the horizontal
Maximal response is seen within 30-60s Descending aortic blood flow of ge10 or
echocardiographic subaortic flow of ge12 ---- fluid responsiveness
Utility of PLR outside the critical care environment is questionable
Clinical Assessment of Volume Status

JVP Indication of the pressure in the right atrium
NOT a direct measure of volume A measurement of gt3 cm from sternal angle (gt8 cm from
RA) is taken as evidence of high RA pressure in normal patients
Many conditions that can result in an elevated JVP eg RV failure TR or TS pericardial effusion or constrictive pericarditis SVC obstruction Volume overload

This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients
RA distance to be 8 cm 97 cm and 98 cm at 30 45 and 60 degrees elevation respectively There is considerable inter-subject variability with dependent variables including age smoking status and AP chest diameter

Differentiating Prerenal vs Intrinsic Renal
FENa () = UNa x SCr x 100
SNa x UCr
FEUrea () = Uurea x SCr x 100
BUN x UCr
None of the above criteria for the diagnosis of prerenal disease may be present in a patient with underlying
renal disease
No recent diuretics
In the absence of hemorrhagic shock use isotonic crystalloids rather than colloids (albumin or starches) as initial management for expansion of intravascular volume
Use of vasopressors in conjunction with fluids in patients with vasomotor shock
Use protocol-based management of hemodynamic and oxygenation parameters to prevent development or worsening of AKI in high-risk patients in the perioperative setting or in patients with septic shock

Effect of Low-dose Dopamine on Need for RRT
Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Use continuous and intermittent RRT as complementary therapies in AKI patients
Use CRRT rather than standard intermittent RRT for hemodynamically unstable patients
Use CRRT rather than intermittent RRT for AKI patients with acute brain injury or other causes of increased intracranial pressure or generalized brain edema
Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

J Am Coll Cardiol 2008521527-1539
Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

Skin turgor No diagnostic value
Physiological Response to fluid challenge Changes in physiological parameters eg MAP HR
CVP after rapid administration of intravenous fluid over a short time
No data on the optimum technique or its diagnostic reliability
Physiological Response to Passive Leg raising Moving the patient from a semi-recumbent position
to a supine position with passive elevation of the legs to 45ordm above the horizontal
Maximal response is seen within 30-60s Descending aortic blood flow of ge10 or
echocardiographic subaortic flow of ge12 ---- fluid responsiveness
Utility of PLR outside the critical care environment is questionable
Clinical Assessment of Volume Status
AKI a competency network Academy of Medical Royal College 2011
JVP Indication of the pressure in the right atrium
NOT a direct measure of volume A measurement of gt3 cm from sternal angle (gt8 cm from
RA) is taken as evidence of high RA pressure in normal patients
Many conditions that can result in an elevated JVP eg RV failure TR or TS pericardial effusion or constrictive pericarditis SVC obstruction Volume overload

Am J Med198783(5)905-8
This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients
RA distance to be 8 cm 97 cm and 98 cm at 30 45 and 60 degrees elevation respectively There is considerable inter-subject variability with dependent variables including age smoking status and AP chest diameter

Differentiating Prerenal vs Intrinsic Renal
FENa () = UNa x SCr x 100
SNa x UCr
FEUrea () = Uurea x SCr x 100
BUN x UCr
None of the above criteria for the diagnosis of prerenal disease may be present in a patient with underlying
renal disease
No recent diuretics
In the absence of hemorrhagic shock use isotonic crystalloids rather than colloids (albumin or starches) as initial management for expansion of intravascular volume
Use of vasopressors in conjunction with fluids in patients with vasomotor shock
Use protocol-based management of hemodynamic and oxygenation parameters to prevent development or worsening of AKI in high-risk patients in the perioperative setting or in patients with septic shock

Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Use continuous and intermittent RRT as complementary therapies in AKI patients
Use CRRT rather than standard intermittent RRT for hemodynamically unstable patients
Use CRRT rather than intermittent RRT for AKI patients with acute brain injury or other causes of increased intracranial pressure or generalized brain edema
Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

J Am Coll Cardiol 2008521527-1539
Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

JVP Indication of the pressure in the right atrium
NOT a direct measure of volume A measurement of gt3 cm from sternal angle (gt8 cm from
RA) is taken as evidence of high RA pressure in normal patients
Many conditions that can result in an elevated JVP eg RV failure TR or TS pericardial effusion or constrictive pericarditis SVC obstruction Volume overload

This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients
RA distance to be 8 cm 97 cm and 98 cm at 30 45 and 60 degrees elevation respectively There is considerable inter-subject variability with dependent variables including age smoking status and AP chest diameter

Differentiating Prerenal vs Intrinsic Renal
FENa () = UNa x SCr x 100
SNa x UCr
FEUrea () = Uurea x SCr x 100
BUN x UCr
None of the above criteria for the diagnosis of prerenal disease may be present in a patient with underlying
renal disease
No recent diuretics
In the absence of hemorrhagic shock use isotonic crystalloids rather than colloids (albumin or starches) as initial management for expansion of intravascular volume
Use of vasopressors in conjunction with fluids in patients with vasomotor shock
Use protocol-based management of hemodynamic and oxygenation parameters to prevent development or worsening of AKI in high-risk patients in the perioperative setting or in patients with septic shock

Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients
RA distance to be 8 cm 97 cm and 98 cm at 30 45 and 60 degrees elevation respectively There is considerable inter-subject variability with dependent variables including age smoking status and AP chest diameter

None of the above criteria for the diagnosis of prerenal disease may be present in a patient with underlying
renal disease
No recent diuretics
In the absence of hemorrhagic shock use isotonic crystalloids rather than colloids (albumin or starches) as initial management for expansion of intravascular volume
Use of vasopressors in conjunction with fluids in patients with vasomotor shock
Use protocol-based management of hemodynamic and oxygenation parameters to prevent development or worsening of AKI in high-risk patients in the perioperative setting or in patients with septic shock

Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Use continuous and intermittent RRT as complementary therapies in AKI patients
Use CRRT rather than standard intermittent RRT for hemodynamically unstable patients
Use CRRT rather than intermittent RRT for AKI patients with acute brain injury or other causes of increased intracranial pressure or generalized brain edema
Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

JVP Indication of the pressure in the right atrium
NOT a direct measure of volume A measurement of gt3 cm from sternal angle (gt8 cm from
RA) is taken as evidence of high RA pressure in normal patients
Many conditions that can result in an elevated JVP eg RV failure TR or TS pericardial effusion or constrictive pericarditis SVC obstruction Volume overload
J Gen Intern Med 200217(11)852-6Chest 2008134(1)172-8
Am J Med198783(5)905-8
This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients
RA distance to be 8 cm 97 cm and 98 cm at 30 45 and 60 degrees elevation respectively There is considerable inter-subject variability with dependent variables including age smoking status and AP chest diameter

Differentiating Prerenal vs Intrinsic Renal
FENa () = UNa x SCr x 100
SNa x UCr
FEUrea () = Uurea x SCr x 100
BUN x UCr
None of the above criteria for the diagnosis of prerenal disease may be present in a patient with underlying
renal disease
No recent diuretics
In the absence of hemorrhagic shock use isotonic crystalloids rather than colloids (albumin or starches) as initial management for expansion of intravascular volume
Use of vasopressors in conjunction with fluids in patients with vasomotor shock
Use protocol-based management of hemodynamic and oxygenation parameters to prevent development or worsening of AKI in high-risk patients in the perioperative setting or in patients with septic shock

Effect of Low-dose Dopamine on Need for RRT
Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Use continuous and intermittent RRT as complementary therapies in AKI patients
Use CRRT rather than standard intermittent RRT for hemodynamically unstable patients
Use CRRT rather than intermittent RRT for AKI patients with acute brain injury or other causes of increased intracranial pressure or generalized brain edema
Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

Cardiorenal Syndrome
J Am Coll Cardiol 2008521527-1539
Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough

JVP Indication of the pressure in the right atrium
NOT a direct measure of volume A measurement of gt3 cm from sternal angle (gt8 cm from
RA) is taken as evidence of high RA pressure in normal patients
Many conditions that can result in an elevated JVP eg RV failure TR or TS pericardial effusion or constrictive pericarditis SVC obstruction Volume overload

Am J Med198783(5)905-8
This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients
RA distance to be 8 cm 97 cm and 98 cm at 30 45 and 60 degrees elevation respectively There is considerable inter-subject variability with dependent variables including age smoking status and AP chest diameter

None of the above criteria for the diagnosis of prerenal disease may be present in a patient with underlying
renal disease
No recent diuretics
In the absence of hemorrhagic shock use isotonic crystalloids rather than colloids (albumin or starches) as initial management for expansion of intravascular volume
Use of vasopressors in conjunction with fluids in patients with vasomotor shock
Use protocol-based management of hemodynamic and oxygenation parameters to prevent development or worsening of AKI in high-risk patients in the perioperative setting or in patients with septic shock

Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Use continuous and intermittent RRT as complementary therapies in AKI patients
Use CRRT rather than standard intermittent RRT for hemodynamically unstable patients
Use CRRT rather than intermittent RRT for AKI patients with acute brain injury or other causes of increased intracranial pressure or generalized brain edema
Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

Am J Med198783(5)905-8
This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients

Differentiating Prerenal vs Intrinsic Renal
FENa () = UNa x SCr x 100
SNa x UCr
FEUrea () = Uurea x SCr x 100
BUN x UCr
None of the above criteria for the diagnosis of prerenal disease may be present in a patient with underlying
renal disease
No recent diuretics
In the absence of hemorrhagic shock use isotonic crystalloids rather than colloids (albumin or starches) as initial management for expansion of intravascular volume
Use of vasopressors in conjunction with fluids in patients with vasomotor shock
Use protocol-based management of hemodynamic and oxygenation parameters to prevent development or worsening of AKI in high-risk patients in the perioperative setting or in patients with septic shock

Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Use continuous and intermittent RRT as complementary therapies in AKI patients
Use CRRT rather than standard intermittent RRT for hemodynamically unstable patients
Use CRRT rather than intermittent RRT for AKI patients with acute brain injury or other causes of increased intracranial pressure or generalized brain edema
Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

Cardiorenal Syndrome
J Am Coll Cardiol 2008521527-1539
Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients

None of the above criteria for the diagnosis of prerenal disease may be present in a patient with underlying
renal disease
No recent diuretics
In the absence of hemorrhagic shock use isotonic crystalloids rather than colloids (albumin or starches) as initial management for expansion of intravascular volume
Use of vasopressors in conjunction with fluids in patients with vasomotor shock
Use protocol-based management of hemodynamic and oxygenation parameters to prevent development or worsening of AKI in high-risk patients in the perioperative setting or in patients with septic shock

Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Use continuous and intermittent RRT as complementary therapies in AKI patients
Use CRRT rather than standard intermittent RRT for hemodynamically unstable patients
Use CRRT rather than intermittent RRT for AKI patients with acute brain injury or other causes of increased intracranial pressure or generalized brain edema
Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

Repeated exposure of CM should be delayed for 48 hr in patients without risk factors for CI-AKI 72 hr in patients with DM or pre-existing chronic renal
dysfunction Stop nephrotoxic medications eg NSAIDs aminoglycosides
amphotericin B high dose loop diuretics acyclovir ACEIARBs can be continued Consider alternative imaging methods in patients at
increased risk Use the lowest possible dose of contrast medium in patients
at risk
Use iso-osmolar or low osmolar iodinated contrast media rather than high-osmolar iodinated contrast media in patients at risk

Cardiorenal Syndrome
J Am Coll Cardiol 2008521527-1539
Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

JVP Indication of the pressure in the right atrium
NOT a direct measure of volume A measurement of gt3 cm from sternal angle (gt8 cm from
RA) is taken as evidence of high RA pressure in normal patients
Many conditions that can result in an elevated JVP eg RV failure TR or TS pericardial effusion or constrictive pericarditis SVC obstruction Volume overload

Am J Med198783(5)905-8
This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients

None of the above criteria for the diagnosis of prerenal disease may be present in a patient with underlying
renal disease
No recent diuretics
In the absence of hemorrhagic shock use isotonic crystalloids rather than colloids (albumin or starches) as initial management for expansion of intravascular volume
Use of vasopressors in conjunction with fluids in patients with vasomotor shock
Use protocol-based management of hemodynamic and oxygenation parameters to prevent development or worsening of AKI in high-risk patients in the perioperative setting or in patients with septic shock

Effect of Low-dose Dopamine on Need for RRT
Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Use continuous and intermittent RRT as complementary therapies in AKI patients
Use CRRT rather than standard intermittent RRT for hemodynamically unstable patients
Use CRRT rather than intermittent RRT for AKI patients with acute brain injury or other causes of increased intracranial pressure or generalized brain edema
Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

Cardiorenal Syndrome
J Am Coll Cardiol 2008521527-1539
Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

JVP Indication of the pressure in the right atrium
NOT a direct measure of volume A measurement of gt3 cm from sternal angle (gt8 cm from
RA) is taken as evidence of high RA pressure in normal patients
Many conditions that can result in an elevated JVP eg RV failure TR or TS pericardial effusion or constrictive pericarditis SVC obstruction Volume overload
J Gen Intern Med 200217(11)852-6Chest 2008134(1)172-8
Am J Med198783(5)905-8
This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients
RA distance to be 8 cm 97 cm and 98 cm at 30 45 and 60 degrees elevation respectively There is considerable inter-subject variability with dependent variables including age smoking status and AP chest diameter

Differentiating Prerenal vs Intrinsic Renal
FENa () = UNa x SCr x 100
SNa x UCr
FEUrea () = Uurea x SCr x 100
BUN x UCr
None of the above criteria for the diagnosis of prerenal disease may be present in a patient with underlying
renal disease
No recent diuretics
In the absence of hemorrhagic shock use isotonic crystalloids rather than colloids (albumin or starches) as initial management for expansion of intravascular volume
Use of vasopressors in conjunction with fluids in patients with vasomotor shock
Use protocol-based management of hemodynamic and oxygenation parameters to prevent development or worsening of AKI in high-risk patients in the perioperative setting or in patients with septic shock

Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Use continuous and intermittent RRT as complementary therapies in AKI patients
Use CRRT rather than standard intermittent RRT for hemodynamically unstable patients
Use CRRT rather than intermittent RRT for AKI patients with acute brain injury or other causes of increased intracranial pressure or generalized brain edema
Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

Cardiorenal Syndrome
J Am Coll Cardiol 2008521527-1539
Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients

Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed

KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Use continuous and intermittent RRT as complementary therapies in AKI patients
Use CRRT rather than standard intermittent RRT for hemodynamically unstable patients
Use CRRT rather than intermittent RRT for AKI patients with acute brain injury or other causes of increased intracranial pressure or generalized brain edema
Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

J Am Coll Cardiol 2008521527-1539
Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients

When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

J Am Coll Cardiol 2008521527-1539
Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients

Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT

J Am Coll Cardiol 2008521527-1539
Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

JVP Indication of the pressure in the right atrium
NOT a direct measure of volume A measurement of gt3 cm from sternal angle (gt8 cm from
RA) is taken as evidence of high RA pressure in normal patients
Many conditions that can result in an elevated JVP eg RV failure TR or TS pericardial effusion or constrictive pericarditis SVC obstruction Volume overload
J Gen Intern Med 200217(11)852-6Chest 2008134(1)172-8
Am J Med198783(5)905-8
This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients
RA distance to be 8 cm 97 cm and 98 cm at 30 45 and 60 degrees elevation respectively There is considerable inter-subject variability with dependent variables including age smoking status and AP chest diameter

Differentiating Prerenal vs Intrinsic Renal
FENa () = UNa x SCr x 100
SNa x UCr
FEUrea () = Uurea x SCr x 100

None of the above criteria for the diagnosis of prerenal disease may be present in a patient with underlying
renal disease
No recent diuretics
In the absence of hemorrhagic shock use isotonic crystalloids rather than colloids (albumin or starches) as initial management for expansion of intravascular volume
Use of vasopressors in conjunction with fluids in patients with vasomotor shock
Use protocol-based management of hemodynamic and oxygenation parameters to prevent development or worsening of AKI in high-risk patients in the perioperative setting or in patients with septic shock

Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

CI-AKI Risk Score Model for PCI
Repeated exposure of CM should be delayed for 48 hr in patients without risk factors for CI-AKI 72 hr in patients with DM or pre-existing chronic renal
dysfunction Stop nephrotoxic medications eg NSAIDs aminoglycosides
amphotericin B high dose loop diuretics acyclovir ACEIARBs can be continued Consider alternative imaging methods in patients at
increased risk Use the lowest possible dose of contrast medium in patients
at risk
Use iso-osmolar or low osmolar iodinated contrast media rather than high-osmolar iodinated contrast media in patients at risk

Cardiorenal Syndrome
J Am Coll Cardiol 2008521527-1539
Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

Am J Med198783(5)905-8
This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients

None of the above criteria for the diagnosis of prerenal disease may be present in a patient with underlying
renal disease
No recent diuretics
In the absence of hemorrhagic shock use isotonic crystalloids rather than colloids (albumin or starches) as initial management for expansion of intravascular volume
Use of vasopressors in conjunction with fluids in patients with vasomotor shock
Use protocol-based management of hemodynamic and oxygenation parameters to prevent development or worsening of AKI in high-risk patients in the perioperative setting or in patients with septic shock

Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Use continuous and intermittent RRT as complementary therapies in AKI patients
Use CRRT rather than standard intermittent RRT for hemodynamically unstable patients
Use CRRT rather than intermittent RRT for AKI patients with acute brain injury or other causes of increased intracranial pressure or generalized brain edema
Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

Cardiorenal Syndrome
J Am Coll Cardiol 2008521527-1539
Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

JVP Indication of the pressure in the right atrium
NOT a direct measure of volume A measurement of gt3 cm from sternal angle (gt8 cm from
RA) is taken as evidence of high RA pressure in normal patients
Many conditions that can result in an elevated JVP eg RV failure TR or TS pericardial effusion or constrictive pericarditis SVC obstruction Volume overload
J Gen Intern Med 200217(11)852-6Chest 2008134(1)172-8
Am J Med198783(5)905-8
This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients
RA distance to be 8 cm 97 cm and 98 cm at 30 45 and 60 degrees elevation respectively There is considerable inter-subject variability with dependent variables including age smoking status and AP chest diameter

Differentiating Prerenal vs Intrinsic Renal
FENa () = UNa x SCr x 100
SNa x UCr
FEUrea () = Uurea x SCr x 100
BUN x UCr
None of the above criteria for the diagnosis of prerenal disease may be present in a patient with underlying
renal disease
No recent diuretics
In the absence of hemorrhagic shock use isotonic crystalloids rather than colloids (albumin or starches) as initial management for expansion of intravascular volume
Use of vasopressors in conjunction with fluids in patients with vasomotor shock
Use protocol-based management of hemodynamic and oxygenation parameters to prevent development or worsening of AKI in high-risk patients in the perioperative setting or in patients with septic shock

Effect of Low-dose Dopamine on Need for RRT
Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Use continuous and intermittent RRT as complementary therapies in AKI patients
Use CRRT rather than standard intermittent RRT for hemodynamically unstable patients
Use CRRT rather than intermittent RRT for AKI patients with acute brain injury or other causes of increased intracranial pressure or generalized brain edema
Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

RA) is taken as evidence of high RA pressure in normal patients
Many conditions that can result in an elevated JVP eg RV failure TR or TS pericardial effusion or constrictive pericarditis SVC obstruction Volume overload

Am J Med198783(5)905-8
This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients
RA distance to be 8 cm 97 cm and 98 cm at 30 45 and 60 degrees elevation respectively There is considerable inter-subject variability with dependent variables including age smoking status and AP chest diameter

Differentiating Prerenal vs Intrinsic Renal
FENa () = UNa x SCr x 100
SNa x UCr
FEUrea () = Uurea x SCr x 100
BUN x UCr
None of the above criteria for the diagnosis of prerenal disease may be present in a patient with underlying
renal disease
No recent diuretics
In the absence of hemorrhagic shock use isotonic crystalloids rather than colloids (albumin or starches) as initial management for expansion of intravascular volume
Use of vasopressors in conjunction with fluids in patients with vasomotor shock
Use protocol-based management of hemodynamic and oxygenation parameters to prevent development or worsening of AKI in high-risk patients in the perioperative setting or in patients with septic shock

Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Use CRRT rather than intermittent RRT for AKI patients with acute brain injury or other causes of increased intracranial pressure or generalized brain edema
Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

JVP Indication of the pressure in the right atrium
NOT a direct measure of volume A measurement of gt3 cm from sternal angle (gt8 cm from
RA) is taken as evidence of high RA pressure in normal patients
Many conditions that can result in an elevated JVP eg RV failure TR or TS pericardial effusion or constrictive pericarditis SVC obstruction Volume overload
J Gen Intern Med 200217(11)852-6Chest 2008134(1)172-8
Am J Med198783(5)905-8
This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients
RA distance to be 8 cm 97 cm and 98 cm at 30 45 and 60 degrees elevation respectively There is considerable inter-subject variability with dependent variables including age smoking status and AP chest diameter

Differentiating Prerenal vs Intrinsic Renal
FENa () = UNa x SCr x 100
SNa x UCr
FEUrea () = Uurea x SCr x 100
BUN x UCr
None of the above criteria for the diagnosis of prerenal disease may be present in a patient with underlying
renal disease
No recent diuretics
In the absence of hemorrhagic shock use isotonic crystalloids rather than colloids (albumin or starches) as initial management for expansion of intravascular volume
Use of vasopressors in conjunction with fluids in patients with vasomotor shock
Use protocol-based management of hemodynamic and oxygenation parameters to prevent development or worsening of AKI in high-risk patients in the perioperative setting or in patients with septic shock

Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Use continuous and intermittent RRT as complementary therapies in AKI patients
Use CRRT rather than standard intermittent RRT for hemodynamically unstable patients
Use CRRT rather than intermittent RRT for AKI patients with acute brain injury or other causes of increased intracranial pressure or generalized brain edema
Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

No data on the optimum technique or its diagnostic reliability
Physiological Response to Passive Leg raising Moving the patient from a semi-recumbent position
to a supine position with passive elevation of the legs to 45ordm above the horizontal
Maximal response is seen within 30-60s Descending aortic blood flow of ge10 or

JVP Indication of the pressure in the right atrium
NOT a direct measure of volume A measurement of gt3 cm from sternal angle (gt8 cm from
RA) is taken as evidence of high RA pressure in normal patients
Many conditions that can result in an elevated JVP eg RV failure TR or TS pericardial effusion or constrictive pericarditis SVC obstruction Volume overload
J Gen Intern Med 200217(11)852-6Chest 2008134(1)172-8
Am J Med198783(5)905-8
This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients
RA distance to be 8 cm 97 cm and 98 cm at 30 45 and 60 degrees elevation respectively There is considerable inter-subject variability with dependent variables including age smoking status and AP chest diameter

Differentiating Prerenal vs Intrinsic Renal
FENa () = UNa x SCr x 100
SNa x UCr
FEUrea () = Uurea x SCr x 100
BUN x UCr
None of the above criteria for the diagnosis of prerenal disease may be present in a patient with underlying
renal disease
No recent diuretics
In the absence of hemorrhagic shock use isotonic crystalloids rather than colloids (albumin or starches) as initial management for expansion of intravascular volume
Use of vasopressors in conjunction with fluids in patients with vasomotor shock
Use protocol-based management of hemodynamic and oxygenation parameters to prevent development or worsening of AKI in high-risk patients in the perioperative setting or in patients with septic shock

Effect of Low-dose Dopamine on Need for RRT
Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Use continuous and intermittent RRT as complementary therapies in AKI patients
Use CRRT rather than standard intermittent RRT for hemodynamically unstable patients
Use CRRT rather than intermittent RRT for AKI patients with acute brain injury or other causes of increased intracranial pressure or generalized brain edema
Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

J Am Coll Cardiol 2008521527-1539
Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

Skin turgor No diagnostic value
Physiological Response to fluid challenge Changes in physiological parameters eg MAP HR
CVP after rapid administration of intravenous fluid over a short time
No data on the optimum technique or its diagnostic reliability
Physiological Response to Passive Leg raising Moving the patient from a semi-recumbent position
to a supine position with passive elevation of the legs to 45ordm above the horizontal
Maximal response is seen within 30-60s Descending aortic blood flow of ge10 or
echocardiographic subaortic flow of ge12 ---- fluid responsiveness
Utility of PLR outside the critical care environment is questionable
Clinical Assessment of Volume Status
AKI a competency network Academy of Medical Royal College 2011
JVP Indication of the pressure in the right atrium
NOT a direct measure of volume A measurement of gt3 cm from sternal angle (gt8 cm from
RA) is taken as evidence of high RA pressure in normal patients
Many conditions that can result in an elevated JVP eg RV failure TR or TS pericardial effusion or constrictive pericarditis SVC obstruction Volume overload
J Gen Intern Med 200217(11)852-6Chest 2008134(1)172-8
Am J Med198783(5)905-8
This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients
RA distance to be 8 cm 97 cm and 98 cm at 30 45 and 60 degrees elevation respectively There is considerable inter-subject variability with dependent variables including age smoking status and AP chest diameter

Differentiating Prerenal vs Intrinsic Renal
FENa () = UNa x SCr x 100
SNa x UCr
FEUrea () = Uurea x SCr x 100
BUN x UCr
None of the above criteria for the diagnosis of prerenal disease may be present in a patient with underlying
renal disease
No recent diuretics
In the absence of hemorrhagic shock use isotonic crystalloids rather than colloids (albumin or starches) as initial management for expansion of intravascular volume
Use of vasopressors in conjunction with fluids in patients with vasomotor shock
Use protocol-based management of hemodynamic and oxygenation parameters to prevent development or worsening of AKI in high-risk patients in the perioperative setting or in patients with septic shock

Provide nutrition preferentially via enteral route in patients with AKI
Administer protein of 08ndash10 gkgd in noncatabolic AKI patients without need
for dialysis 10ndash15 gkgd in patients with AKI on RRT up to 17 gkgd in patients on CRRT and in
hypercatabolic patients

Effect of Low-dose Dopamine on Need for RRT
Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Use continuous and intermittent RRT as complementary therapies in AKI patients
Use CRRT rather than standard intermittent RRT for hemodynamically unstable patients
Use CRRT rather than intermittent RRT for AKI patients with acute brain injury or other causes of increased intracranial pressure or generalized brain edema
Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

J Am Coll Cardiol 2008521527-1539
Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

Skin turgor No diagnostic value
Physiological Response to fluid challenge Changes in physiological parameters eg MAP HR
CVP after rapid administration of intravenous fluid over a short time
No data on the optimum technique or its diagnostic reliability
Physiological Response to Passive Leg raising Moving the patient from a semi-recumbent position
to a supine position with passive elevation of the legs to 45ordm above the horizontal
Maximal response is seen within 30-60s Descending aortic blood flow of ge10 or
echocardiographic subaortic flow of ge12 ---- fluid responsiveness
Utility of PLR outside the critical care environment is questionable
Clinical Assessment of Volume Status
AKI a competency network Academy of Medical Royal College 2011
JVP Indication of the pressure in the right atrium
NOT a direct measure of volume A measurement of gt3 cm from sternal angle (gt8 cm from
RA) is taken as evidence of high RA pressure in normal patients
Many conditions that can result in an elevated JVP eg RV failure TR or TS pericardial effusion or constrictive pericarditis SVC obstruction Volume overload
J Gen Intern Med 200217(11)852-6Chest 2008134(1)172-8
Am J Med198783(5)905-8
This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients
RA distance to be 8 cm 97 cm and 98 cm at 30 45 and 60 degrees elevation respectively There is considerable inter-subject variability with dependent variables including age smoking status and AP chest diameter

Differentiating Prerenal vs Intrinsic Renal
FENa () = UNa x SCr x 100
SNa x UCr
FEUrea () = Uurea x SCr x 100
BUN x UCr
None of the above criteria for the diagnosis of prerenal disease may be present in a patient with underlying
renal disease
No recent diuretics
In the absence of hemorrhagic shock use isotonic crystalloids rather than colloids (albumin or starches) as initial management for expansion of intravascular volume
Use of vasopressors in conjunction with fluids in patients with vasomotor shock
Use protocol-based management of hemodynamic and oxygenation parameters to prevent development or worsening of AKI in high-risk patients in the perioperative setting or in patients with septic shock

Insulin therapy targeting plasma glucose 110ndash149 mgdl in critically ill patients
Achieve a total energy intake of 20ndash30 kcalkgd in patients with any stage of AKI
Avoid restriction of protein intake with the aim of preventing or delaying initiation of RRT
Provide nutrition preferentially via enteral route in patients with AKI
Administer protein of 08ndash10 gkgd in noncatabolic AKI patients without need
for dialysis 10ndash15 gkgd in patients with AKI on RRT up to 17 gkgd in patients on CRRT and in
hypercatabolic patients

Effect of Low-dose Dopamine on Need for RRT
Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Use continuous and intermittent RRT as complementary therapies in AKI patients
Use CRRT rather than standard intermittent RRT for hemodynamically unstable patients
Use CRRT rather than intermittent RRT for AKI patients with acute brain injury or other causes of increased intracranial pressure or generalized brain edema
Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

Cardiorenal Syndrome
J Am Coll Cardiol 2008521527-1539
Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

JVP Indication of the pressure in the right atrium
NOT a direct measure of volume A measurement of gt3 cm from sternal angle (gt8 cm from
RA) is taken as evidence of high RA pressure in normal patients
Many conditions that can result in an elevated JVP eg RV failure TR or TS pericardial effusion or constrictive pericarditis SVC obstruction Volume overload
J Gen Intern Med 200217(11)852-6Chest 2008134(1)172-8
Am J Med198783(5)905-8
This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients
RA distance to be 8 cm 97 cm and 98 cm at 30 45 and 60 degrees elevation respectively There is considerable inter-subject variability with dependent variables including age smoking status and AP chest diameter

Effect of Low-dose Dopamine on Need for RRT
Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Use CRRT rather than intermittent RRT for AKI patients with acute brain injury or other causes of increased intracranial pressure or generalized brain edema
Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

Skin turgor No diagnostic value
Physiological Response to fluid challenge Changes in physiological parameters eg MAP HR
CVP after rapid administration of intravenous fluid over a short time
No data on the optimum technique or its diagnostic reliability
Physiological Response to Passive Leg raising Moving the patient from a semi-recumbent position
to a supine position with passive elevation of the legs to 45ordm above the horizontal
Maximal response is seen within 30-60s Descending aortic blood flow of ge10 or
echocardiographic subaortic flow of ge12 ---- fluid responsiveness
Utility of PLR outside the critical care environment is questionable
Clinical Assessment of Volume Status
AKI a competency network Academy of Medical Royal College 2011
JVP Indication of the pressure in the right atrium
NOT a direct measure of volume A measurement of gt3 cm from sternal angle (gt8 cm from
RA) is taken as evidence of high RA pressure in normal patients
Many conditions that can result in an elevated JVP eg RV failure TR or TS pericardial effusion or constrictive pericarditis SVC obstruction Volume overload
J Gen Intern Med 200217(11)852-6Chest 2008134(1)172-8
Am J Med198783(5)905-8
This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients
RA distance to be 8 cm 97 cm and 98 cm at 30 45 and 60 degrees elevation respectively There is considerable inter-subject variability with dependent variables including age smoking status and AP chest diameter

Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

Clinical Assessment of Volume Status
AKI a competency network Academy of Medical Royal College 2011
JVP Indication of the pressure in the right atrium
NOT a direct measure of volume A measurement of gt3 cm from sternal angle (gt8 cm from
RA) is taken as evidence of high RA pressure in normal patients
Many conditions that can result in an elevated JVP eg RV failure TR or TS pericardial effusion or constrictive pericarditis SVC obstruction Volume overload
J Gen Intern Med 200217(11)852-6Chest 2008134(1)172-8
Am J Med198783(5)905-8
This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients
RA distance to be 8 cm 97 cm and 98 cm at 30 45 and 60 degrees elevation respectively There is considerable inter-subject variability with dependent variables including age smoking status and AP chest diameter

KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

This systematic review demonstrated a very poor relationship between CVP and blood volume as well as the inability of CVPCVP to predict the hemodynamic response to a fluid challenge CVP should not be used to make clinical decisions regarding fluid management
Clinical assessment was only able to identify 47 of hypovolemic patients and 48 of normovolemic patients in the setting of hyponatremia whereas the spot urine Na clearly separated hypovolemic from normovolemic patients

Differentiating Prerenal vs Intrinsic Renal
FENa () = UNa x SCr x 100
SNa x UCr
FEUrea () = Uurea x SCr x 100
BUN x UCr
None of the above criteria for the diagnosis of prerenal disease may be present in a patient with underlying
renal disease
No recent diuretics
In the absence of hemorrhagic shock use isotonic crystalloids rather than colloids (albumin or starches) as initial management for expansion of intravascular volume
Use of vasopressors in conjunction with fluids in patients with vasomotor shock
Use protocol-based management of hemodynamic and oxygenation parameters to prevent development or worsening of AKI in high-risk patients in the perioperative setting or in patients with septic shock

Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

Differentiating Prerenal vs Intrinsic Renal
FENa () = UNa x SCr x 100
SNa x UCr
FEUrea () = Uurea x SCr x 100
BUN x UCr
None of the above criteria for the diagnosis of prerenal disease may be present in a patient with underlying
renal disease
No recent diuretics
In the absence of hemorrhagic shock use isotonic crystalloids rather than colloids (albumin or starches) as initial management for expansion of intravascular volume
Use of vasopressors in conjunction with fluids in patients with vasomotor shock
Use protocol-based management of hemodynamic and oxygenation parameters to prevent development or worsening of AKI in high-risk patients in the perioperative setting or in patients with septic shock

Ann Intern Med 2005142510ndash524
Effect of Low-dose Dopamine on Need for RRT
Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Use continuous and intermittent RRT as complementary therapies in AKI patients
Use CRRT rather than standard intermittent RRT for hemodynamically unstable patients
Use CRRT rather than intermittent RRT for AKI patients with acute brain injury or other causes of increased intracranial pressure or generalized brain edema
Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

Cardiorenal Syndrome
J Am Coll Cardiol 2008521527-1539
Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Differentiating Prerenal vs Intrinsic Renal
FENa () = UNa x SCr x 100
SNa x UCr
FEUrea () = Uurea x SCr x 100
BUN x UCr
None of the above criteria for the diagnosis of prerenal disease may be present in a patient with underlying
renal disease
No recent diuretics
In the absence of hemorrhagic shock use isotonic crystalloids rather than colloids (albumin or starches) as initial management for expansion of intravascular volume
Use of vasopressors in conjunction with fluids in patients with vasomotor shock
Use protocol-based management of hemodynamic and oxygenation parameters to prevent development or worsening of AKI in high-risk patients in the perioperative setting or in patients with septic shock

Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT

Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Use continuous and intermittent RRT as complementary therapies in AKI patients
Use CRRT rather than standard intermittent RRT for hemodynamically unstable patients
Use CRRT rather than intermittent RRT for AKI patients with acute brain injury or other causes of increased intracranial pressure or generalized brain edema
Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

J Am Coll Cardiol 2008521527-1539
Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Use continuous and intermittent RRT as complementary therapies in AKI patients
Use CRRT rather than standard intermittent RRT for hemodynamically unstable patients
Use CRRT rather than intermittent RRT for AKI patients with acute brain injury or other causes of increased intracranial pressure or generalized brain edema
Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

J Am Coll Cardiol 2008521527-1539
Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement

Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Cardiorenal Syndrome
J Am Coll Cardiol 2008521527-1539
Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Use continuous and intermittent RRT as complementary therapies in AKI patients
Use CRRT rather than standard intermittent RRT for hemodynamically unstable patients
Use CRRT rather than intermittent RRT for AKI patients with acute brain injury or other causes of increased intracranial pressure or generalized brain edema
Modality of RRT for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI
Deliver an effluent volume of 20-25 mlkgh for CRRT in AKI

Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Advantages and Disadvantages of Each RRT Modality
The dose of RRT to be delivered should be prescribed before starting each session of RRT
Frequently assess of the actual delivered dose in order to adjust the prescription
Provide RRT to achieve the goals of electrolyte acid-base solute and fluid balance that will meet the patientrsquos needs
Deliver a KtV of 39 per week when using intermittent or extended RRT in AKI

Effect of Low-dose Dopamine on Mortality
Ann Intern Med 2005142510ndash524
Effect of Low-dose Dopamine on Need for RRT
Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed
Prevention of Aminoglycoside- andAmphotericin-related AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Initiate RRT emergently when life-threatening changes in fluid electrolyte and acid-base balance exist
Consider the broader clinical context the presence of conditions that can be modified with RRT and trends of laboratory tests rather than single BUN and creatinine thresholds alone to start RRT
Discontinue RRT when it is no longer required either because intrinsic kidney function has recovered to the point that it is adequate to meet patient needs or because RRT is no longer consistent with the goals of care
Do NOT use diuretics to enhance kidney function recovery or to reduce the duration or frequency of RRT
Dialysis Intervention for Treatment of AKI
KDIGO Guideline 2012 ndash AKI KI Supplements 20122(1)1-138
Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

Do NOT use aminoglycosides to treat infections unless no suitable less nephrotoxic therapeutic alternatives are available
In patients with normal kidney function in steady state aminoglycosides are administered as a single dose daily rather than multiple-dose daily treatment regimens
Monitor aminoglycoside drug levels when treatment with single-daily dosing is used for gt48 hours
Use topical or local applications of aminoglycosides (eg respiratory aerosols instilled antibiotic beads) rather than IV when feasible and suitable
Use azole agents echinocandins or lipid formulations rather than conventional formulations of amphotericin B if equal therapeutic efficacy can be assumed

Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years

Potential Applications for RRT
Initiate RRT in patients with AKI via an uncuffed nontunneled dialysis catheter rather than a tunneled catheter
When choosing a vein for insertion of a dialysis catheter in patients with AKI consider these preferences- First choice = Right IJ vein Second choice = Femoral vein Third choice = Left IJ vein Last choice = SC vein with preference for the dominant side
Use a subclavian site rather than a jugular or a femoral site in adult patients to minimize infection risk for nontunneled CVC placement
Use ultrasound guidance for dialysis catheter insertion CXR after placement and before first use of IJ or SC catheter Use a CVC with the minimum number of ports or lumens
essential for the management of the patient

Cardiorenal Syndrome
J Am Coll Cardiol 2008521527-1539
Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

CI-AKI Risk Score Model for PCI
Repeated exposure of CM should be delayed for 48 hr in patients without risk factors for CI-AKI 72 hr in patients with DM or pre-existing chronic renal
dysfunction Stop nephrotoxic medications eg NSAIDs aminoglycosides
amphotericin B high dose loop diuretics acyclovir ACEIARBs can be continued Consider alternative imaging methods in patients at
increased risk Use the lowest possible dose of contrast medium in patients
at risk
Use iso-osmolar or low osmolar iodinated contrast media rather than high-osmolar iodinated contrast media in patients at risk

Cardiorenal Syndrome
J Am Coll Cardiol 2008521527-1539
Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

Cardiorenal Syndrome
J Am Coll Cardiol 2008521527-1539
Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Repeated exposure of CM should be delayed for 48 hr in patients without risk factors for CI-AKI 72 hr in patients with DM or pre-existing chronic renal
dysfunction Stop nephrotoxic medications eg NSAIDs aminoglycosides
amphotericin B high dose loop diuretics acyclovir ACEIARBs can be continued Consider alternative imaging methods in patients at
increased risk Use the lowest possible dose of contrast medium in patients
at risk
Use iso-osmolar or low osmolar iodinated contrast media rather than high-osmolar iodinated contrast media in patients at risk

Cardiorenal Syndrome
J Am Coll Cardiol 2008521527-1539
Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine

Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Use of a macrocyclic chelate is preferred over linear chelate Gd
Use the lowest dosage possible to achieve the image Avoid repeat exposure with Gd Consider performing intermittent hemodialysis after exposure
and next 2 days in patients who are already maintained on HD
Demonstration of significant quantities of insoluble Gd in the skin of NSF patients months after exposure to Gd based contrast material and after extensive tissue processing

Type 1 acute decrease in cardiac function leads to acute kidney injury
Type 2 chronic decrease in cardiac function leads to progressive CKD
Type 3 acute kidney injury leads to acute cardiac dysfunction
Type 4 chronic kidney disease leading to decreased cardiac function cardiac hypertrophy andor increased risk of adverse cardiovascular events
Type 5 Systemic condition (eg sepsis) causing both cardiac and renal dysfunction
Cardiorenal Syndrome
J Am Coll Cardiol 2008521527-1539
Patient wakes up at five AM with acute shortness of breath and ldquoheartburnrdquo
He takes Lomicid and tries to go back to sleep despite continued pain
The pain continues off and on for the next 8 hours before he relents and follows his co-workers advice and goes to be evaluated by a doctor
In the ER he is found to have a troponin T of 15 His shortness of breath initially improved with IV Lasix but
over the next 24 hours it worsens along with increasing oxygen requirement
His SCr on admission was 14 and rises over the next few days to 34 mgdl with his worsening hemodynamics

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

Diuretic Strategies in Patients with Acute Decompensated Heart Failure
N Engl J Med 2011364(9)797-805
A 78 year old male has ischemic heart disease with left-sided heart failure
The patient had a series of admissions over the summer of 2010 due to recurrent decompensated heart failure but has since remained out of the hospital on the following regimen
bull Lasix 40 mg daily bull HCTZ 125 mg Mondays and Thursdays bull Carvedilol 25 mg bid bull Lisinopril 20 mg daily bull Aldactone 25 mg daily
Along with the improved heart failure management his creatinine has gradually risen from 14 to 28 and his BUN now runs around 70-80 mgdl
A 68 year old patient with compensated heart failure is maintained on the following regimen lisinopril 20 mg furosemide 40 mg bid metoprolol 100 mg bid
She presents to clinic with a blood pressure of 16595 labs show a potassium of 56 and a creatinine at baseline 16
Her internist adds HCTZ 25 mg daily for the potassium and blood pressure Her follow-up chemistries and blood pressure are improved and stable
She calls back 2 weeks later complaining of swollen hot red right big toe A diagnosis of acute gout is made and she is prescribed Celebrex 400 mg daily
Three days later she presents to the ER with shortness of breath palpitations and peripheral edema Her potassium is 68 and creatinine is 36
58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

Use hemodynamic monitoring when possible to help with the management of fluid balance in patients with HRS
Resuscitate patients with HRS type 1 with albumin (initially 1 g of albuminkg for two days up to a maximum of 100 gday followed by 20 to 40 gday) in combination with a vasoconstrictor preferentially terlipressin
RRT should be avoided in HRS type 1 patients unless there is either an acute reversible component or a plan for liver transplantation
Management
Crit Care 201216R231-17
Extracorporeal Liver Support System
Crit Care 201216R231-17
Treatment of HRS type 1 is vasoconstrictor + albumin liver transplantationTreatment of HRS type 2 is large volume paracentesis with albumin administration 8 g1 L of ascites removed liver transplantation

58 year old patient with diabetic nephropathy has been on dialysis for 3 years
He has finally agreed to explore kidney transplant As part of the work-up she gets a stress echocardiogram
He has a non-ischemic response but is found to have significant left ventricular hypertrophy
56 year old Caucasian woman is admitted with fever shortness of breath and one week of productive cough
CXR shows right middle lobe infiltrate
At admission her vitals were stable except for a temp of 1023 Soon after she decompensated and her blood pressure falls to 70 systolic She is started on dopamine
She is ultimately admitted to the MICU and intubated The following day her creatinine has risen from 12 to 25 and a bedside echo shows an LVEF of 30 down from 65 2 months ago

Use hemodynamic monitoring when possible to help with the management of fluid balance in patients with HRS
Resuscitate patients with HRS type 1 with albumin (initially 1 g of albuminkg for two days up to a maximum of 100 gday followed by 20 to 40 gday) in combination with a vasoconstrictor preferentially terlipressin
RRT should be avoided in HRS type 1 patients unless there is either an acute reversible component or a plan for liver transplantation
