Effects of centrifugal and roller pumps on survival of autologous red cells in cardiopulmonary bypass surgery

Abstract

The 24-h post-transfusion survival values of autologous RBC, measured by the 51 disodium chromate/99m technetium double isotope procedure, were not significantly different, whether the roller pump or the centrifugal pump was used in the extracorporeal circuit using membrane oxygenators during cardiopulmonary surgical procedures.
