The potential of preoperative autologous blood donation to reduce intraoperative homologous blood transfusions in a municipal hospital.

The possibility of introducing autologous blood donation as a standard procedure in elective surgery is investigated, taking as an example a typical tertiary care municipal hospital. Homologous blood transfusions were necessary in 808 of a total of 10,128 cases. In 109 out of 311 cases, which amounts to 35% of all cases with elective surgery and homologous blood transfusion, autologous blood transfusion would retrospectively have been possible, saving a total of 327 blood units.
