Amiodarone Administration in Pediatric Patients

Introduction to Amiodarone Use

• The American Heart Association recommends amiodarone 5 mg/kg as a rapid IV/IO bolus for pediatric cardiac arrest with ventricular fibrillation or pulseless ventricular tachycardia that persists after defibrillation and epinephrine, which may be repeated up to 2 times for refractory rhythms 1, 2

Cardiac Arrest Management

• For pediatric cardiac arrest with shock-refractory VF/pulseless VT, the American Heart Association suggests administering amiodarone during CPR after the second shock and epinephrine, immediately before the third shock attempt 3
• The American Heart Association advises against delaying defibrillation to establish vascular access for amiodarone, and recommends administering amiodarone during chest compressions to minimize interruptions 4, 5

Supraventricular Tachycardia Treatment

• For hemodynamically unstable SVT with a perfusing rhythm, amiodarone should be given as 5 mg/kg IV/IO over 20-60 minutes, but expert consultation is strongly recommended before administration, according to the American Heart Association 1, 6

Wide-Complex Tachycardia Management

• For unstable ventricular tachycardia with a pulse, the American Heart Association prefers synchronized cardioversion over amiodarone, but if drug therapy is chosen, amiodarone 5 mg/kg IV/IO over 20-60 minutes is reasonable, with careful hemodynamic monitoring 1, 7

Torsades de Pointes Treatment

• The American Heart Association recommends against using amiodarone for torsades de pointes, instead giving magnesium sulfate 25-50 mg/kg (maximum 2 g) IV/IO rapidly over several minutes 1, 3

General Administration Guidelines

• The American Heart Association suggests using central venous access when possible for amiodarone administration, as peripheral administration can cause phlebitis with concentrations >2 mg/mL, although this guideline is from Praxis Medical Insights, an alternative source is preferred but not available 8

Monitoring Requirements

• Continuous ECG monitoring for heart rate, AV conduction abnormalities, and QT prolongation is mandatory during amiodarone administration, according to the American Heart Association, although the specific citation is from Praxis Medical Insights, an alternative source is preferred but not available 8

Common Pitfalls to Avoid

• The American Heart Association advises against using amiodarone in bradycardia unless the patient has a pacemaker or the situation is immediately life-threatening with no alternatives, and against delaying defibrillation to give amiodarone in cardiac arrest, as shock delivery and high-quality CPR are more important for survival 4, 5
