What energy dose range is recommended for synchronized cardioversion in pediatric VT with a pulse?

What energy dose range is recommended for synchronized cardioversion in pediatric VT with a pulse?

• A. 2–4 J/kg
• B. 5–10 J/kg
• C. 0.1–0.2 J/kg
• D. 0.5–1 J/kg

Answer: (D)

In pediatric VT with a pulse, the aim is to restore a perfusing rhythm with the smallest effective energy to minimize myocardial injury. The starting energy for synchronized cardioversion in children is 0.5–1 J/kg, delivered in synchronization with the R wave to avoid delivering energy on the vulnerable portion of the cycle. If the first attempt doesn’t convert the rhythm, a second dose of 1–2 J/kg is used. The other ranges are either too low to reliably cardiovert or too high for an initial pediatric shock, increasing the risk of adverse effects. So the recommended starting dose is 0.5–1 J/kg.
