How does pediatric resuscitation differ from adult resuscitation in defibrillation energy dosing?

• A. Pediatric and adult use the same fixed energy.
• B. Pediatric dosing is weight-based (2 J/kg initial, 4 J/kg subsequent) with device limits, unlike fixed adult energies.
• C. Pediatric uses higher energies than adults.
• D. Pediatric uses only medication, not defibrillation.

Answer: (B)

In pediatric resuscitation, defibrillation energy is scaled to the child’s weight rather than using one fixed energy for everyone. The first shock is delivered at 2 joules per kilogram, and subsequent shocks at 4 joules per kilogram, with a safeguard that the energy cannot exceed the defibrillator’s maximum output. This approach is necessary because children vary widely in size and chest impedance, so a fixed adult energy can be either ineffective or potentially harmful. Using weight-based dosing aims to reliably terminate the rhythm while minimizing myocardial injury. For example, a 10 kg child would receive about 20 J initially and 40 J for the next shock, limited by the device’s maximum if needed. In larger children, the calculated 4 J/kg for subsequent shocks might exceed the device’s maximum, so you would cap at the device limit. This combination of weight-based dosing with device limits is what distinguishes pediatric defibrillation from adult practice.
