AbstractForty patients who were scheduled for a total hip arthroplasty were enrolled in a prospective study and were randomly divided into two groups. Group 1 received recombinant human erythropoietin (300 U/kg twice a week), and group 2 received placebo. The medication was started 2 weeks before the operation, and only one dose of medication was given after the operation. Autologous blood was administered at the same time as the medication until the hemoglobin level sank to 10 g/dl. Forty-eight and 49 units of autologous blood were collected in group 1 and group 2, respectively. Intraoperative homologous blood was transfused only to patients in group 2. Seven and 13 units of allogenic blood were transfused into group 1 and group 2 patients during the postoperative period, respectively. There were no any significant differences between the groups in terms of early postoperative hemoglobin level and amount of autologous blood collected. However, the increase of the reticulocyte count in patients who received erythropoietin was significantly higher than in the group 2 patients. The study showed that short-term and low-dose erythropoietin usage strongly stimulates the bone marrow. Erythropoietin administration and preoperative autologous blood donation diminished the total units of allogenic blood required during the intraoperative or postoperative period. Autologous blood administration without concurrent erythropoietin did not stimulate the bone marrow adequately.
