How is adenosine administered for pediatric SVT?

Adenosine must be given by rapid IV push via the most proximal vein possible, immediately followed by a 5–10 mL NS flush. Slow administration leads to inactivation before reaching the cardiac tissue due to the 10-second half-life.

What is the second-dose adenosine amount?

Second dose is 0.2 mg/kg (maximum 12 mg) if the first dose fails to terminate SVT. If SVT persists after two doses, cardioversion or alternative antiarrhythmics such as amiodarone or procainamide should be considered.

Adenosine SVT Pediatric Dose

Calculate adenosine dose for pediatric SVT conversion: 0.1 mg/kg (maximum 6 mg) first dose, 0.2 mg/kg (maximum 12 mg) second dose, administered by rapid IV push followed by saline flush.
