AUTOLOGOUS TRANSFUSIONS FOR ORTHOPEDIC PROCEDURES AT A CHILDRENS HOSPITAL

We conducted a critical review of the use of autologous transfusions in orthopaedics at a tertiary-care children's hospital. The cases of 198 children who deposited blood before an orthopaedic operation were analyzed. There were 175 children who were enrolled in the program of preoperative deposit of autologous blood who later needed transfusion of blood; 73 per cent of them received only autologous blood. Seventy patients also had intraoperative salvage. We were unable to document a proved benefit of intraoperative salvage of blood in this group of patients. Forty patients had some difficulty donating autologous blood preoperatively, but these problems were rarely serious. Major human errors occurred in thirteen patients and resulted in some patients receiving homologous transfusions while autologous blood components were still available. Fifty-five (40 per cent) of all of the transfusions were administered in clinical circumstances that failed to meet generally accepted criteria for transfusion, and fifty-four (38 per cent) of the postoperative transfusions also failed to meet these criteria. This was true of the homologous transfusions in the study as well. Although an autologous blood transfusion is a generally safe procedure, it is not without risk, and human errors can occur. In light of the potential complications, surgeons should adhere to the standard indications for transfusion when administering autologous blood.
