[Usefulness of the combined transfusion of autologous blood as pre-deposited and preoperatively diluted in gynecological surgery].

To eliminate the risks involved in homologous blood transfusion in gynecological surgery, we studied the effect of the combined transfusion of autologous blood as predeposited and preoperatively diluted. Thirty-nine cases were operated on and studied. In 27 cases, a total of 695 ml/person of autoblood was taken during the 15 preoperative days. In 39 cases, an average of 1,038 ml/person of autoblood was collected at the beginning of surgery. In 37 out of 39 cases, we were able to avoid homologous blood transfusion. In the remaining two cases with homologous blood transfusion, although more than 3,000 ml of operative blood loss was observed, only about 700 ml of homologous blood was needed. We did not find any serious side effect with autoblood transfusion. These results demonstrate the usefulness of the combined transfusion of autologous blood as predeposited and preoperatively diluted in gynecological surgery.
