Evaluation of Intraoperative Bivalirudin Anticoagulation in Neonates and Infants Undergoing Arterial Switch Operation on Integrated ECMO-CPB Circuit: A Prospective Study

J Cardiothorac Vasc AnesthPublished Pilot study

Authors' conclusion

Bivalirudin can be effectively used for anticoagulation during CPB in neonates and infants with transposition of great arteries, at a bolus dose of 1 mg/kg and a maintenance dose of 2.1 ± 0.3 mg/kg/h, utilizing the integrated extracorporeal membrane oxygenation-CPB circuit.
