Advantages of Local Anesthesia
• The patient is conscious during surgery.
• Smooth postoperative course.
• Patient awake and maintains his own airway.
• Less pain needs less narcotics, lighter anesthesia in general cases.
• Less nursing care after procedures, less admissions.
• Less expensive
3
Disadvantages of Local Anesthesia
• The patient may prefer to be asleep
• Specialized skill necessary.
• Some blocks require up to 30 minutes to be fully effective.
• Analgesia may not always be totally effective, and general anesthesia may be required anyway.
4
Disadvantages of Local Anesthesia
• Generalized toxicity may occur if local anesthetic drugs are given intravenously by mistake or an overdose is given.
• Widespread sympathetic blockade can result in hypotension.
• There is a small but definite incidence of prolonged nerve damage.

Local Anesthetics
• Agent: Dose: Onset/Duration: • Lidocaine with epi (1 or 2%) 7mg/kg Fast/medium • Lidocaine without epi 4.5mg/kg Fast/short • Mepivacaine without epi (3%) 5.5mg/kg Fast/short • Bupivacaine with epi (0.5%) 1.3mg/kg Long/long • Articaine with epi (4.0%) 7mg/kg Fast/medium
*ADULT DOSES IN PATIENTS WITHOUT CARDIAC HISTORY
