AbstractThe efficacy, safety and diagnostic usefulness of adenosine in the treatment of supraventricular tachycardia in children were prospectively studied over a 2-year period. Only patients who were stable and without hypotension were included. Adenosine was given at a dose of 0.1 mg/kg and increased to 0.2 mg/kg for the second and third doses if there was no response. Adenosine was used on 5 occasions in 5 patients. Adenosine was found to be effective in terminating supraventricular tachycardia in all 5 patients; 4 responded to a dose of 0.2 mg/kg while 1 responded to 0.1 mg/kg. Wolff-Parkinson White Syndrome was detected in 2 patients after termination of supraventricular tachycardia. Transient hypotension was noted in 1 patient lasting 45 seconds with no haemodynamic consequences. Two patients had transient ventricular ectopics lasting 3 to 5 seconds. One out of 3 patients who were old enough to report side-effects, experienced chest discomfort and dizziness lasting 5 seconds. All side-effects were transient and mild. We concluded that adenosine is effective and safe in terminating supraventricular tachycardia in children after vagal manoeuvres have failed.
