For a cardiac arrest in adult ACLS, what is the first dose of amiodarone recommended?

In the case of a cardiac arrest during adult Advanced Cardiac Life Support (ACLS), the first recommended dose of amiodarone is 300 mg if the patient is in a shockable rhythm such as ventricular fibrillation (VF) or pulseless ventricular tachycardia (VT). This is part of the algorithm for managing such arrhythmias, where administering a high dose of amiodarone helps stabilize the heart's rhythm after defibrillation attempts.

The purpose of this dose is to improve the chance of restoring a normal rhythm. If the arrhythmia persists after the first shock and administration of the initial dose of amiodarone, subsequent doses of 150 mg may be administered, which allows for a more tailored approach to treatment as the resuscitation progresses.

This specific dosing regimen is based on guidelines from prominent cardiac care associations, ensuring that emergency medical providers have clear and standardized instructions to follow in critical situations. It is essential to distinguish this correct initial dose from higher or lower doses that may not align with established protocols.
