DEFINITION
CLASSIFICATION
PARTIAL SEIZURE
/FOCAL
SEIZURE
GENERALISED SEIZURE
CLASSIFICATION
PARTIAL SEIZURE / FOCAL SEIZURE(AFFECT / BEGIN IN ONE PART OF THE BRAIN)
SIMPLE COMPLEX(CONCIOUSNESS REMAIN INTACT)1. MOTOR Jerking Muscle Rigidity Head Turning
2. SENSORY (Unusual sensation affect ) Visual Hearing Taste Touch
3. PSCYCHOLOGY Emotional Memory disturbance
(IMPAIRMENT OF CONCIOUSNESS)
Begin in one part of brain and spreading to another part of brain.
Postictal Symptoms (Seizure State)
Aura Phase Motionless / Automatic
movement but inappropiate Excessive emotion – irritate /
anger etc Not remember when episode is
over.
Leading to Generalised Seizure
GENERALISED SEIZUREABSENSE SEIZURE (PETIT-MAL)
Sudden onsetDuration 5-10 sec / happen 100x dailyCommonly cause by
STRESSFatigueHypoglycemia
Some known as ‘day dreaming’Sign & Symptoms
LOR but still maintain postureTwitching eyelids / Lips smackingLong starring (most common)
GENERALISED SEIZUREMYOCLONIC SEIZURE
• Movement Disorder• Seen when awake / fall asleep• Cause by touch / visual stimuli• Symmetrical / Asymmetrical• Sign & Symptoms :
No LOCSudden and simpleShoclike involuntaryDropping things (most common)
• 90% individuals who have syncope hx.
GENERALISED SEIZURETONIC SEIZURE
• Muscle are maintained in continuous contracted state. (Rigidity)
• Sign & Symptoms :Variable LOCPupils dilatedEyes roll upPossible incontinenceMay foam at mouth
GENERALISED SEIZURECLONIC SEIZURE
• Opposing muscle contract and relax alternately. (Jerking)
• May occur only one limb or more.
• Sign & Symptoms :• Mucus production• Muscle Stiffness
GENERALISED SEIZURETONIC-CLONIC SEIZURE
(GRAND-MAL)• Violent total body seizure
• Sign & Symptoms :Usually LOC / CollapseTonic phase (30-60 sec)Clonic phasePostictal Symptoms - Apneic
TONIC – CLONIC PHASE
GENERALISED SEIZUREATONIC SEIZURE
• Drop or fall attack• Loss of posture tone
UNCLASSIFIED SEIZURE
• FEBRILE FIT Convulsion associated with a HIGH GRADE (38C) body
temperature. They most commonly occur in children between the ages of 6 months and 5 years of age
• STATUS EPILEPTICUS Acute prolonged seizure activity. Ictus more than 15-20 min. Series of generalized seizures that occur without full
recovery of consciousness between attacks
• EPILEPSY Group of syndromes characterized by unprovoked, recurring
seizures Ictus more than 30 min.
1. Cerebral Vascular Accident (CVA)2. Central Nervous System (CNS) Infection3. Head Injury / Trauma4. Hypoxemia / Anoxia5. Hypertension6. Metabolic / Toxic Condition7. Brain Tumour8. Drugs and Alcohol Withdrawal9. Fever in childhood
ETIOLOGY
PATHOPHYSIOLOGYETIOLOGY
Many neurons fire in a synchronous pattern, resulting
in a transient physiologic disturbance
Physiologic disturbances
include abnormal movements,
abnormal sensations and change in LOC

APPOACH TO SEIZURE
ASSESSMENT FINDINGS
Aimed to determine:1. Type of seizure2. Frequency 3. SeverityAuraLOCDyspneaFixed and dilated pupilIncontinence
4. Factors that precipitate them.5. Developmental history taking (events of pregnancy and
childbirth)6. Questioned about illnesses or head injury
APPROACH TO SEIZURE
MANAGEMENT
• Provide privacy and protect the patient from curios on-lookers,
• Ease the patient to the floor or the lowest position, if possible.
• Protect the head with a pad to prevent injury (from striking a hard surface)
• Loosen constrictive clothing• Push aside any furniture that may injure the
patient during the seizure.
APPROACH TO SEIZURE
MANAGEMENT
• Do not attempt to pry open jaws that are clenched in a spasm to insert anything. Broken teeth and injury to the lips and tongue may result from such an action
• No attempt should be made to restrain the patient during the seizure because muscular contractions are strong and restraint can produce injury
• If possible, place the patient on one side with head flexed forward, which allows the tongue to fall forward and facilitates drainage of saliva and mucus. If suction is available, use it if necessary to clear secretions
Guidelines for Seizure Care
APPROACH TO SEIZUREMEDICATION MANAGEMENT
Rx GOAL : Prevent neuronal injury to the brain ( 20 min – 1hour)
FIRST LINE THERAPY (Benzodiazephines) : Diazepam (Valium) / Lorazepam• Function as Anti-convulsants : To prevent the prolonged time in seizure.• Diazepam (Valium)
• IV : Adults – 5 – 10 mg/kg , Peads – 0.2 mg/kg• Per Rectal 10 mg (> 5 min) – IV access unsuccessful – 0.5 mg/kg/dose
• Lorazepam - IV : 0.1 mg/kg
SECOND LINE THERAPY (Phenobarbital) : Phenytoin (Cerebyx) • Function as Anti-Epileptic• Patient still in aggressive seize after first line therapy.
• IV : 20 mg/kg usually use doses 1 gram in ED• Need BP & cardiac monitoring – develop hypotension and cardiac arrythmias
THIRD LINE THERAPY (Sedative) : Propofol / Midazolam• Function more as sedation• Greater sedative effect and more effective in infusion.
• Propofol IV 2-5 mg/kg – IVI : 20 – 100 mcg/kg/min• Midazolam IV 0.2 mg/kg – IVI : 0.05 – 2 mg/kg/h
APPROACH TO SEIZUREMEDICAL MANAGEMENT
• Diet: Ketogenic (a diet high in fats and proteins, and low in carbohydrates)
• I.V. therapy: Secure line. Give medication.• Activity: bed rest• Monitoring: Vital signs, I/O chart• Laboratory studies: glucose, potassium, and
anticonvulsant drug levels if applicable.• Special care: seizure precautions- ABC ,
temperature, blood glucose, spinal care• Anticonvulsants: phenytoin (Dilantin), Valium
(Diazepam), Lorazepam (Ativan)
INVESTIGATION• BLOOD INVESTIGATION : RBS , ABG • EEG: abnormal wave patterns, focus of seizure
activity• CT scan: a space occupying lesion• MRI: pathologic changes / tissue lession• Lumbar Puncture: need pt consideration
Persistent fever/AMS/headache
POSTICTAL STATE CARE(after seizure)
• Keep the patient on one side to prevent aspiration. Make sure the airway is patent
• There is usually a period of confusion after a grand mal seizure
• A short apneic (sleeping) period may occur during or immediately after a generalized seizure
• The patient, on awakening, should be reoriented to the environment
• If the patients becomes agitated after a seizure (postictal), use calm persuasion and gentle restraint
PATIENT EDUCATION
• Take medications at regular basis• Avoid alcohol. This lowers seizure threshold• Adequate rest• Well-balanced diet• Avoid driving, operating machines, swimming until
seizures are well controlled• Lead an active life• Parents/relative education
