Many advances in blood conservation techniques are currently being applied during coronary artery bypass grafting (CABG). These include the use of cell saving to enhance intraoperative blood salvage,1–3 the use of large-bore directional cannulae to minimize shear forces and platelet activation and loss,4 the routine use of antifibrinolytic agents,5–7 normothermic bypass to diminish coagulopathy,8 low-prime cardiopulmonary bypass to diminish dilution of coagulation factors, the use of “tip-to-tip” heparin-bonded cardiopulmonary bypass circuits,9 and postoperative reinfusion of shed blood.10 Despite the proven efficacy of these blood conservation techniques, they have been uniformly applied to all patients undergoing CABG because of their complexity and cost. Consequently, as many as 30% to 70% of patients undergoing CABG still require transfusions.1–3
