Blood salvage for cardiovascular surgeryBaylor College of Medicine, Houston, Texas Intraoperative blood salvage produces safe and clinically effective red cells. Intraoperative salvage for cardiovascular surgery procedures can be expected to cause a substantial reduction in the use of homologous red cells in patients requiring redo operations, and repair of complex aortic aneurysms. The procedure per se will have very little impact on the use of other blood components such as platelets or plasma. For carefully selected patients, autologous perioperative or intraoperative collection of these components should also be considered. The primary risks of intraoperative blood transfusion include washout of clotting proteins and platelets, infusion of undesirable constituents (such as antibiotics and haemostatic agents added during the surgical procedure) and air embolism. Intraoperative autologous transfusion is only one part of an effective programme to minimize homologous transfusion. Equally important is the use of preoperatively donated blood, the use of effective and safe pharmacological agents to enhance haemostasis and haematopoiesis, a conservative approach that allows only the transfusion of blood components absolutely necessary, and, when possible, the elimination of anticoagulant and antiplatelet therapy several days prior to the cardiovascular surgical procedure.
