What is the initial dosage of adenosine for treating pediatric SVT?

The initial dosage of adenosine for treating pediatric supraventricular tachycardia (SVT) is indeed 0.1 mg/kg. This dosage is recommended for the rapid termination of symptomatic SVT in children. Adenosine works by temporarily interrupting the conduction through the atrioventricular node, allowing the normal sinus rhythm to regain control.

In pediatric patients, careful consideration is given to weight-based dosing, which is essential for ensuring efficacy while minimizing potential side effects. The recommended initial dose of 0.1 mg/kg can be administered rapidly as a bolus. If the first dose is ineffective, subsequent doses can be doubled, but it's important to administer them quickly and in succession to achieve the desired therapeutic effect.

Understanding this dosage is crucial in emergency medicine and critical care settings, as prompt recognition and treatment of SVT can prevent complications associated with prolonged tachycardia. This knowledge is vital for paramedics and other providers working with pediatric patients.
