What is the recommended first dose of lidocaine during ACLS?

• A. 1-1.5 mg/kg
• B. 0.5-1 mg/kg
• C. 2-3 mg/kg
• D. 0.1-0.3 mg/kg

Answer: (A)

In ACLS, lidocaine is used as an IV antiarrhythmic for ventricular arrhythmias, and the first dose should be 1-1.5 mg/kg given rapidly as a bolus. This dose quickly achieves therapeutic levels to help terminate or suppress the arrhythmia during CPR. If needed, a second dose of 0.5-0.75 mg/kg can be given every 5-10 minutes, up to a total max of 3 mg/kg. Monitor for signs of lidocaine toxicity, and use lidocaine as an option when amiodarone isn’t available or the rhythm remains refractory.
