When should amiodarone be considered during pediatric arrest?

• A. In shock-refractory VT/VF after defibrillation
• B. In all arrests immediately
• C. Only after CPR is completed
• D. If asystole is present

Answer: (A)

Amiodarone is used in pediatric arrest only for a rhythm that is shockable and does not convert after defibrillation. When VT or VF is present and initial defibrillation attempts do not terminate the rhythm, an antiarrhythmic like amiodarone is given to stabilize the heart rhythm and reduce the chance of recurrent VT/VF. This makes it the best choice after defibrillation has failed to restore a normal rhythm.

It isn’t used in all arrests, because non-shockable rhythms such as asystole or PEA do not benefit from antiarrhythmic drugs like amiodarone; those situations are managed with high-quality CPR and vasopressors like epinephrine. And amiodarone isn’t given before attempting defibrillation for a shockable rhythm—the priority is to deliver defibrillation first, then administer amiodarone if the rhythm remains VT/VF.

Typical dosing in pediatrics is a 5 mg/kg IV/IO bolus, up to a total of about 15 mg/kg, with repeats only if persistent VF/VT continues.
