Study Notes

Lidocaine Overview

  • Brand name: Xylocaine

Classification

  • Classified as an antiarrhythmic medication.

Mechanism of Action

  • Blocks sodium channels to stabilize cardiac membranes.
  • Increases recovery period after repolarization.
  • Suppresses automaticity and depolarization of ventricles.

Indications

  • Used for ventricular arrhythmias, particularly when Amiodarone is unavailable.
  • Effective in cardiac arrest scenarios, especially for ventricular fibrillation (V-Fib) and ventricular tachycardia (V-Tach).

Contraindications

  • Contraindicated in patients with atrioventricular (AV) block.
  • Avoid use in conditions like Adams-Stokes Syndrome and Wolff-Parkinson-White Syndrome.

Side Effects

  • Potential side effects include toxicity and seizures.
  • Risk of cardiac arrhythmias, hypotension, and cardiac arrest.

Dosage Guidelines

  • Adults: In cardiac arrest, administer 1.0-1.5 mg/kg IV/IO, maximum of 3.0 mg/kg; second dose of 0.5-0.75 mg/kg.
  • Continuous drip rate should be between 1-4 mg/min.
  • For perfusion ventricular tachycardia (VT), administer 0.5-0.75 mg IV/IO with a maintenance infusion of 1-4 mg/min.
  • Pediatrics: 1 mg/kg, with a maximum dosage of 100 mg; infusion rate of 20-50 mcg/kg/min.
