Autologous blood transfusion for elective surgery.

Between September 1983 and June 1985, 336 patients were assessed by the Autologous Blood Transfusion Service; 267 men, mean age, 65 (range, 16-75) years, and 40 women, mean age, 63 (range, 40-70) years, participated in the programme (29 patients were excluded as unsuitable). Orthopaedic and vascular surgery accounted for 80% of the cases. Complications were minor even in this elderly group. Surgical and transfusion details for a one-month period were studied retrospectively. Of the surgical cases that required crossmatched blood, 50% were for "emergency" and "burn" surgery, and 50% for elective surgery. Forty-five per cent of this latter group were unsuitable as autologous donors, 21% had participated in the autologous blood transfusion programme, and an additional 34% were deemed to be suitable donors. The realistic upper limits of our autologous blood transfusion programme were determined as being 55% of elective cases that require crossmatched blood. To be efficient an autologous blood transfusion service must be incorporated into an existing homologous blood transfusion service and must complement, rather than replace, homologous blood transfusion.
