In pediatric resuscitation, what is the initial energy for defibrillation?

• A. 1 J/kg
• B. 3 J/kg
• C. 2 J/kg
• D. 4 J/kg

Answer: (C)

In pediatric resuscitation, defibrillation energy is carefully tailored to the child’s weight and the device type, aiming to deliver enough energy to terminate a shockable rhythm without causing unnecessary myocardial injury. For modern biphasic defibrillators, the recommended starting energy is 2 J/kg. If the first shock doesn’t restore rhythm, you escalate to 4 J/kg for subsequent shocks. This lower initial dose reflects the pediatric heart’s increased sensitivity to electrical injury and the need to minimize damage while still achieving defibrillation. The other values aren’t the standard starting dose: 1 J/kg is usually too low to reliably terminate a shockable rhythm, 3 J/kg isn’t the standard starting dose, and 4 J/kg is used for subsequent shocks (or as an initial dose with older monophasic devices), not the preferred starting energy in contemporary practice.
