Contraindication

Hypovolaemia; heart block or other conduction disturbances.

Mode of Action

Lidocaine is an amide type local anaesth. It stabilises the neuronal membrane and inhibits Na ion movements, which are necessary for conduction of impulses. In the heart, lidocaine reduces depolarisation of the ventricles during diastole and automaticity in the His-Purkinje system. Duration of action potential and effective refractory period are also reduced.

Precaution

Hepatic or renal impairment; CHF and following cardiac surgery; bradycardia; respiratory depression; porphyria; elderly or debilitated patients; pregnancy. Lactation: Distributed in human breast milk; caution advised

Side Effect

Application site reactions Abnormal sensation,Pallor or blanching when the application time is very prolonged (>2 hr),Alterations in temperature sensations,Edema,Itching,Rash Systemic reactions Unlikely due to the small dose absorbed; may occur with repeated doses or application to large surface area CNS excitation and/or depression Light-headedness, nervousness, apprehension, euphoria, confusion Dizziness,Drowsiness,Tinnitus,Blurred or double vision,Vomiting,Sensations of heat, cold or numbness,Twitching, tremors, convulsions.Unconsciousness, respiratory depression, and arrest.Cardiovascular manifestations (eg, bradycardia, hypotension, and cardiovascular collapse leading to arrest) Potentially Fatal: Hypotension and bradycardia leading to cardiac arrest; anaphylaxis.

Interaction

May increase serum levels w/ cimetidine and propranolol. Increased risk of cardiac depression w/ beta-blockers and other antiarrhythmics. Additive cardiac effects w/ IV phenytoin. Hypokalaemia caused by acetazolamide, loop diuretics and thiazides may antagonise effect of lidocaine. Dose requirements may be increased w/ long-term use of phenytoin and other enzyme-inducers.
