AbstractPerioperative hemorrhage associated with major orthopaedic surgery can become life threatening. Homologous bank blood transfusion can replace the volume of blood lost but it has serious disadvantages such as the transmission of viral agents, it has an insufficient platelet count, and transfusion reactions are possible. Hypotensive anesthesia, predeposited autologous blood transfusion and intraoperative autotransfusion are used to reduce these disadvantages. This study evaluates the results of 700 patients who underwent major orthopaedic intervention in our clinic between June 1991 and April 1998. Ninety-nine patients had hip surgery while 601 patients had spinal surgery. The autotransfusion unit saved an average of 858.9 +/- 136.8 cc of blood and an average of 1.9 +/- 1.2 units of saved blood was transfused. None of these patients needed homologous blood transfusion. One hundred patients who had spinal surgery during the same period were used as a control group. The control group required an average of 3.2 +/- 2.1 units of bank blood. Preoperative and postoperative hematocrit values revealed a statistically significant difference between the autotransfusion group and the homologous transfusion group (p < 0.05). The results of this study suggest that intraoperative autotransfusion prevents the decrease in hematocrit values while reducing the need for bank blood transfusion and hence avoiding the risk of transmission of viral infections.
