In a prospective study, 60 patients posted for coronary artery bypass graft (CABG) surgery on cardiopulmonary bypass (CPB) were assigned to 2 groups of 30 each. (group A =combination of acute normovolaemic haemodilution (ANH) and retrograde autologous priming (RAP), group B=control). The aim was to investigate whether retrograde autologous priming reduces haemoditution as compared to control cases.

Retrograde autologous priming (RAP) is a blood conservation technique used to limit the severity of hemodilution during cardiopulmonary bypass and reduce perioperative transfusions. The aim of this investigation was to examine the safety of RAP and to determine the effect of RAP on adverse outcomes after cardiac surgery.

Extreme haemodilution occurring with cardiopulmonary bypass imposes a primary risk factor for blood transfusion in small adult cardiac surgical patients. Priming of the cardiopulmonary bypass circuit with patients' own blood [retrograde autologous priming (RAP)] is a technique used to limit haemodilution and reduce transfusion requirements.

The aim of this study was to investigate the effect of retrograde autologous priming (RAP) of the cardiopulmonary bypass (CPB) circuit on cerebral oxygenation.

The purpose of this study was to determine which factors impact the ability to perform autologous priming (AP) of the extracorporeal circuit.

A literature review and meta-analysis were undertaken to assess the clinical effectiveness of retrograde autologous priming of the cardiopulmonary bypass circuit to reduce allogeneic packed red blood transfusions in adult cardiac surgery.
