Preoperative autologous blood donation in hip surgeries

We evaluated the effectiveness of preoperative autologous blood donation in reduction of the need for transfusion of homologous blood in hip surgeries at our hospital. The cases of 55 patients who had 67 hip surgeries, including 17 total hip arthroplasties (THA) and 41 rotational acetabular osteotomies (RAO), were studied. The patients predeposited an average of 995 ml of blood for each procedure. The calculated blood loss was an average of 961 ml. Ninety-seven percent of the procedures for which autologous blood had been predeposited were performed without transfusion of homologous blood. In the group for THA, an average of 981 ml of autologous blood was transfused for a blood loss of 1417 ml; hemoglobin levels after operation averaged 103 g/l. From this data, a 1000 ml donation seemed to be an optimal blood deposit for THA and a 800 ml blood deposit seemed sufficient for RAO, where the patients are younger.
