What is the dosing of Etomidate for pediatric unstable SVT?

• A. 0.15 mg/kg IV/IO
• B. 0.2 mg/kg
• C. 0.3 mg/kg
• D. 0.5 mg/kg

Answer: (A)

Etomidate is favored for sedation in an unstable pediatric SVT because it provides rapid hypnosis with minimal impact on blood pressure and heart function. In this situation, you need quick, reliable sedation to perform cardioversion without worsening perfusion or causing significant hemodynamic derangement. The best dosing choice uses a small, single IV/IO bolus within the pediatric induction range, which delivers fast onset and a brief duration, allowing quick control of the rhythm while preserving cardiovascular stability. A higher dose increases the risk of apnea and greater respiratory depression, which can be dangerous in an unstable patient. A dose that is too small may not achieve adequate sedation for safe cardioversion. So, this lower induction dose strikes the right balance between rapid, effective sedation and maintaining hemodynamic stability.
