What is the first dose for pediatric SVT?

• A. 0.2 mg/kg Rapid IVP
• B. 0.1 mg/kg Rapid IVP
• C. 0.3 mg/kg Rapid IVP
• D. 0.05 mg/kg Rapid IVP

Answer: (B)

Adenosine is used to interrupt the reentrant pathway causing narrow-complex, regular SVT in a stable child by briefly blocking AV node conduction. The first dose is 0.1 mg/kg given as a rapid IV push, with a maximum of 6 mg. Because adenosine acts for only a few seconds, it’s delivered quickly and followed by a rapid saline flush to ensure it reaches the heart before it wears off. If there’s no conversion, you administer a second dose of 0.2 mg/kg (maximum 12 mg). For example, a 20 kg child would get 2 mg initially, then 4 mg if needed.
