What is the recommended dosage of lidocaine administered during CPR?

The recommended dosage of lidocaine during CPR is 1 mg/kg administered via intravenous (IV) or intraosseous (IO) route. This dosage is typically used in cases of ventricular arrhythmias or during cardiac arrest scenarios where advanced life support protocols are in effect.

Lidocaine acts as an antiarrhythmic medication, specifically targeting ventricular ectopy and ventricular fibrillation. The 1 mg/kg dosage is based on evidence that has shown it to be effective in stabilizing cardiac activity and decreasing the likelihood of recurrent arrhythmias during resuscitation efforts. This dosing strategy is essential in a resuscitation algorithm, as it allows for immediate action to address life-threatening irregular rhythms while minimizing the risk of drug toxicity.

The focus on using this specific dosage reflects current guidelines, ensuring it aligns with best practices for maximizing patient outcomes in critical situations.
