Key result
Single-syringe diluted adenosine rapidly terminates supraventricular tachycardia in a neonate.
Why the study?
Adenosine administration for neonatal SVT can be cumbersome and may require equipment not always readily available, motivating evaluation of a simpler single-syringe method.
Case Report (n=1)
May facilitate rapid neonatal SVT termination; hypothesis-generating and requires prospective validation before practice change.
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.

McDowell et al. (2020) conducted a case report in Neonatal Supraventricular Tachycardia (n=1). Single-syringe adenosine was evaluated on Termination of supraventricular tachycardia to normal sinus rhythm. Administration of 0.2 mg/kg adenosine diluted in a single syringe safely and effectively achieved near-immediate return to normal sinus rhythm in a 4-week-old neonate with supraventricular tachycardia.
