What is the dosing recommendation for adenosine in kids with PSVT?

The dosing recommendation for adenosine in children with paroxysmal supraventricular tachycardia (PSVT) is indeed 0.1 mg/kg for the first dose, followed by 0.2 mg/kg for the second dose if needed. This approach is based on the pharmacological characteristics of adenosine, which has a very short half-life and can be rapidly effective in terminating reentrant tachycardias. The initial lower dose is designed to minimize the risk of adverse effects while still being effective. If the first dose does not achieve the desired effect of restoring normal sinus rhythm, the higher second dose can be administered to enhance efficacy.

This dosing method ensures that the child receives appropriate care, balancing the need for rapid intervention while reducing potential side effects associated with higher doses. Understanding this recommended approach is crucial for healthcare providers in managing pediatric patients with PSVT effectively.
