Blood conservation in major orthopedic surgery

During an eight-year period, intraoperative autotransfusion was performed in 1922 operations. There were 476 primary hip arthroplasties, 1017 revision hip arthroplasties, 339 spinal procedures, and 90 vascular cases. There were no known complications related to autotransfusion in any of the cases. With proper technique, red cell salvage is approximately 58% effective, and intraoperative blood loss can be reduced by that amount. The first four years' experience with the preoperative autogeneic blood program is as follows. Using a combined program of predonation and primary hip arthroplasty, 72% of the revision hip arthroplasties and 81% of the spinal instrumentations required only autologous blood. A combined program of autologous donation and intraoperative autotransfusion is an excellent alternative to allogeneic blood replacement and a means of eliminating transfusion-related disease.
