A Case Report of Neonatal Supraventricular Tachycardia Resolved with Single-Syringe Adenosine

INTRODUCTION: Supraventricular tachycardia (SVT) is a condition requiring emergency care in neonates. CASE REPORT: We describe a successfully treated case of neonatal SVT in a four-week-old neonate using the novel adenosine administration method. This technique is potentially easier to facilitate and does not require equipment such as a stopcock. Adenosine 0.2 milligrams per kilogram was drawn up into a syringe containing 0.9% sodium chloride to a total volume of 3 milliliters. Once administered, the patient had near-immediate return to normal sinus rhythm without sequelae. CONCLUSION: This case demonstrates that the single-syringe method appears potentially safe and effective in neonates.
