Abstract
Anemia is associated with adverse outcomes after surgery, especially in the elderly persons. We have reviewed retrospective data on 435 elderly patients who underwent total hip or knee replacement to establish preoperative risk factors associated with postoperative anemia requiring red blood cell transfusion. The multiple logistic regression analysis was used to identify predictors of allogeneic blood transfusion. Independent risk factors for allogeneic blood transfusion were a low preoperative haemoglobin level, low patient’s weight, revision joint replacements and preoperative intravenous injections of tranexamic acid. Our data allow to assess the risk of postoperative severe anemia and to develop targeted intervention to decrease the risk.
