Abstract
In orthopedic surgery,osteotomies require blood transfusions for bleeding from the bone with hemostatic difficulties. In1988 we started collecting blood for autotransfusion in order to avoid allogeneic transfusion. Autologous cryoprecipitate purified from the collected blood has been used during surgery since 1999. We investigated the benefit of autologous cryoprecipitate by statistically comparing our patients who underwent rotational acetabular osteotomy. Thirty patients were randomly assigned to 2groups, with or without autologous cryoprecipitate. Statistical comparison showed no significant differences in the amount of intraoperative and postoperative bleeding and the increase or decrease of cellular components. The autologous cryoprecipitate is expected to be useful for various applications such as fixation of bone fragments and rapid healing of wounds in addition to hemostasis. We should examine and evaluate other factors of autologous cryoprecipitate to determine its usefulness in osteotomy.
