Abstract
Predeposit autologous donation for elective surgical procedures during which there is a potential requirement for transfusion is medically proven as safe and efficacious but significantly underutilized. The primary advantages are avoidance of transfusion-transmitted disease and alloimmunization. Appropriate donor selection is essential. In general, there are no age or weight limits for donors. The incidence of adverse reactions is no greater in properly selected autologous donors than in homologous donors. Administration of oral ferrous sulfate allows many patients to meet all of their perioperative transfusion requirements. The blood is usually stored in the liquid state, but can be frozen. The mere availability of autologous blood is not an indication for its reinfusion. The criteria for transfusion are similar to those for homologous blood. However, a more liberal interpretation may be appropriate in some clinical situations. The issue of disposition of predonated blood which is not transfused to donor-patients remains unresolved. In some areas all units are discarded. In others, the blood can be administered to other patients if the donor met all the criteria for homologous donors and the blood tested negative for infectious disease markers.
