Background Revision total hip arthroplasty (RTHA) is known to entail some risk of hemorrhage during the intraoperative period. Preoperative autologous blood donation (PAD) is one of the most popular alternatives to allogeneic blood transfusion (ABT) in elderly patients undergoing major orthopedic procedures in which a substantial blood loss is expected. The aim of this study was to evaluate the effectiveness of a combination of PAD and intravenous tranexamic acid (TXA) in reducing the need for ABT following RTHA. Patients and methods A total of 60 patients were included in this randomized study that were divided into a study group of 30 patients, who had been transfused autologous blood and a control group of 30 patients who had been transfused only allogeneic blood. Parenteral iron preparation was given to all patients of the study group after each donation. Intraoperatively all patients of the study group received 2 g of intravenous TXA. This study was conducted through laboratory analysis of hemoglobin and hematocrit values during blood donation and for both groups in the preoperative and the postoperative period and the assessment of the amount of transfused blood units in both groups. Results The average values of hemoglobin and hematocrit in the first and the second donation were 11.9±1.2 g/dl, 36.1±3.8%, and 11.9±1.0 g/dl, 35.6±3.5%, respectively. During operative and postoperative periods, the statistical data processing showed that there was a nonsignificant difference between the study and control groups regarding the number of transfused blood units (both autologous and allogeneic) (P=0.578 and 0.089), respectively, and only 10% of patients in the study group needed allogeneic blood. Conclusion PAD combined with intraoperative intravenous TXA administration reduced the number of ABTs in patients who underwent RTHA.
