Administration of several adenosine boluses successfully reverted supraventricular tachycardia and achieved hemodynamic stability in a neonate presenting with cardiogenic shock.
Case Report (n=1)
Sudden vascular changes resembling cutis marmorata in neonates should raise suspicion for cardiogenic shock caused by an underlying arrhythmia like SVT, which can be successfully treated with adenosine.
We report a case of a patient admitted to the neonatal intensive care unit at birth for grunting and respiratory distress. A diagnosis was made after the patient presented with signs of serious poor perfusion and cardiorespiratory monitoring showed a rapid cardiac rhythm suggesting supraventricular tachycardia (SVT). Hemodynamic stability was achieved after several adenosine boluses and the SVT was reverted. Episodes of SVT are characterized by abrupt onset and termination and regular narrow QRS complex tachycardia without P waves. This diagnosis should be kept in mind in neonates when a sudden vascular change resembling cutis marmorata happens since it can suggest cardiogenic shock caused by an underlying arrhythmia.

Joana et al. (2021) conducted a case report in Neonatal Supraventricular Tachycardia (n=1). Adenosine was evaluated on Hemodynamic stability and reversion of SVT. Administration of several adenosine boluses successfully reverted supraventricular tachycardia and achieved hemodynamic stability in a neonate presenting with cardiogenic shock.
