Autologous blood transfusion in revision hip arthroplasty. A prospective, controlled study of 30 patients.

In a prospective, randomized study of the efficacy and effects of autologous blood transfusion in revision hip arthroplasty, 30 patients were randomly allocated into two groups. The Control Group received homologous blood transfusion. The Study Group deposited 2-3 units of blood preoperatively, intraoperative blood salvage was used, and no homologous blood was transfused intraoperatively. There was a smaller postoperative blood loss in the Study Group. The preoperative hemoglobin values were lower in the Study Group, but one week postoperatively they were higher than in the Control Group. The decrease in the values of AT III and protein C was lower in the Study Group. The combination of preoperative blood donation and intraoperative blood salvage reduced blood loss and homologous blood transfusion in revision hip arthroplasty.
