Intraoperative Autologous Transfusion

Abstract: Intraoperative autologous transfusion is a technique that was first used almost 2 centuries ago but that has realized its potential only in the past 5 years. A growing national awareness of transfusion-related morbidity, of the need for alternative blood sources, and of improved methods for red blood cell recovery has led to an increased frequency of use of autologous transfusion. Most hospital programs use semicontinuous flow centrifugation or canister technology for the intraoperative salvage and reinfusion of shed blood. This technique is particularly valuable for cardiovascular surgical procedures but has been useful in many other types of surgical procedures as well. Deleterious effects formerly attributed to this technique have been eliminated by methodologic improvements. Concerns about use of autologous transfusion in patients who have an infection or a malignant lesion persist. Most hematologic aberrations are related to massive transfusions and should not be considered a contraindication to the general use of autologous blood.

Autologous blood transfusion.

Abstract: Autologous blood transfusion is a procedure in which blood is removed from a donor and returned to his circulation at some later time. Autologous transfusion can be performed in three ways: (1) preoperative blood collection, storage, and retransfusion during surgery; (2) immediate preoperative phlebotomy with subsequent artificial hemodilution and later return of the phlebotomized blood; and (3) intraoperative blood salvage and retransfusion. All three methods of autologous transfusion offer a potentially superior method of blood transfusion which eliminates many of the problems and complications associated with the banking and administration of homologous donor blood.
