Adenosine administration with a stopcock is the recommended treatment for pediatric patients with acute supraventricular tachycardia. Recent reports suggest that many infants do not respond to the first dose of adenosine administered. Our aim is to determine whether administration of adenosine with a stopcock delivers lower-than-expected drug doses in patients weighing less than 10 kg, corresponding to weights of infants. ⋯ Administration of adenosine through a stopcock delivers doses lower than intended in patients weighing less than 10 kg, which may account for the decreased response of infants to the first dose of adenosine.
