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.
