Association Between Postoperative Dexmedetomidine Use and Arrhythmias in Infants After Cardiac Surgery.

Background: Dexmedetomidine has been suggested as an arrhythmia prophylactic agent after surgery for congenital heart disease due to its heart rate lowering effect, though studies are conflicting. We sought to study the effect of dexmedetomidine in infants that are at highest risk for arrhythmias.

Methods: Retrospective cohort study of infants less than six months of age undergoing cardiopulmonary bypass for congenital heart disease.
