Retrograde Autologous Priming Technique to Reduce Hemodilution during Cardiopulmonary Bypass in the Pediatric Cardiac Patient

Abstract

Blood conservation techniques during pediatric congenital heart surgery continue to be a vital strategy in reducing hemodilution during cardiopulmonary bypass. Development of mini circuits, retrograde autologous priming, modified ultrafiltration, and use of a cell saver are methods adopted by pediatric heart programs to limit transfusions. Excessive hemodilution may warrant the need for transfusion in the pediatric patient, which carries significant risks in the overall care of the patient. Retrograde autologous priming is a safe and effective way to limit the amount of hemodilution, and thereby reduce the need for transfusion.
