RESUMO
The efficacy of perioperative autotransfusion (PAT) can be evaluated by the reduction in homologous transfusion accompanying its use. An alternative approach is to evaluate the amount of blood salvaged and retransfused. An analysis of 9,918 consecutive PAT procedures in various surgical specialties revealed that the average return of autologous blood salvaged was equivalent to 2.61 units of erythrocytes ("packed cells"). Cardiac operation had the greatest average number of units recovered (4.65), while orthopedic operation had the least (1.05). This method of analysis demonstrates that significant quantities of blood can be salvaged during PAT procedures.

The Southern Arizona Regional Red Cross blood program offers preoperative autologous blood deposit to all patients and intraoperative autotransfusion services to all hospitals in the region. During a 5-year period, the amount of preoperatively deposited autologous blood and intraoperatively salvaged red cells available increased from 0.3 to 19.6 percent of the community's total collections. Further increases in the availability and use of autologous blood may be achieved by community-wide integration of services.

The Southern Arizona Regional Red Cross Blood Program, in cooperation with two cardiac surgery groups, examined the effect of intraoperative autotransfusion on red cell, plasma, and platelet usage during and after cardiac operations. The study evaluated whether intraoperative autotransfusion influenced intraoperative or postoperative blood usage and whether regular use was more effective than selective use. The study demonstrated that intraoperative autotransfusion reduces intraoperative and postoperative blood use and that regular use of intraoperative autotransfusion is more effective than selective use.

The application of autologous and frozen red blood cell (RBC) programs is described for 3 pregnant women with antibodies to high-incidence blood group antigens (anti-Lutheranb, anti-Cellano, anti-Vel). The cases illustrate how readily available supplies or rare blood types can be maintained throughout pregnancy using autologous and frozen RBC techniques, including selective predeposit, "family-sharing," and intensive phlebotomy with fluid replacement. The RBC phenotypes described in this paper are exceedingly rare since they occur in only 0.1-0.001% of random donors. However, the principles of autologous blood transfusions are universal and they can be applied to the general problems of blood group incompatibility in pregnancy.
