What is the initial defibrillation energy for pediatric patients, and what is the dosing pattern for subsequent shocks?

• A. 2 J/kg for initial shock; subsequent shocks usually 4 J/kg; use weight-based dosing.
• B. 4 J/kg initially; then 2 J/kg.
• C. 1 J/kg for all shocks.
• D. 3 J/kg initial; 3 J/kg subsequent.

Answer: (A)

In pediatric defibrillation, doses are tailored to the child’s size. The recommended approach is to start with a low, weight-based energy and then increase for subsequent shocks if needed. The first shock is delivered at 2 J/kg, and if the rhythm remains shockable or recurs, subsequent shocks are delivered at 4 J/kg. Using weight-based dosing helps ensure the energy is sufficient to terminate the arrhythmia without causing unnecessary myocardial injury, and clinicians often estimate weight with a Broselow tape or other quick methods to calculate the correct joule dose. If the child’s weight is unknown, default to the 2 J/kg initial and 4 J/kg subsequent pattern and adjust as soon as weight is estimated.
