AbstractTotal hip and knee arthroplasty is associated with significant perioperative blood loss, necessitating often blood transfusions. Because of risks and cost of allogenic blood transfusion and elective types of surgery several alternative methods have been developed to reduce allogenic blood use. We prospectively audited 65 consecutive patients undergoing primary total hip (THR; n = 30) or knee replacement (TKR; n = 35) at our Department of Orthopaedic Surgery which did not use autologous blood collection methods. Total blood loss in THR (1329.7 +/- 364.8 ml) and TKR (1427.3 +/- 660.4 ml) was similar to previously reported and without significant difference between the groups. However, we reported high transfusion rates with 63.3% of THR and 82.6% of TKR patients receiving allogenic blood. Important steps to reduce allogenic blood use would include implementation of restrictive transfusion protocols with a defined hemoglobin value as a transfusion trigger, correction of preoperative anemia with i.v. iron +/- erythropoietin, use of one or more modalities of autologous transfusion (postoperative autotransfusion, preoperative blood donation), pharmacological agents like tranexamic acid (anti-fibrinolytic) and other complementary procedures. There is sufficient evidence in literature about the cost-benefit of certain methods which makes routine use of allogenic blood in THR and TKR surgery unacceptable even at general orthopaedic surgery departments.
