How to best administer Adenosine for SVT? Single syringe? 3 Way Stopcock? Two Syringe?

The American Heart Association 2015 guidelines for Adult Advanced Cardiac Life Support recommends adenosine in nonhypotensive patients in regular narrow‐complex SVT. Adenosine is an endogenous purine nucleoside that blocks atrioventricular nodal conduction via the A1 receptors in the cardiac tissue. These in turn act on Gi‐cAMP to stimulate potassium channels yielding hyperpolarization of cardiac myocytes thus returning the heart to a normal sinus rhythm (NSR). The pharmacokinetic profile of adenosine makes it an ideal agent to treat SVT. With a rapid onset and a half‐life less than 10 seconds, cardioversion can be performed quickly with limited adverse effects. Due to these unique kinetics, a large‐volume flush of saline is concomitantly administered to ensure adequate delivery to the myocardium. Adenosine is commonly administered as a 6‐mg rapid intravenous bolus over 1 to 2 seconds followed by a rapid 20‐mL saline flush.
