title: [Preoperative collection of autologous blood with recombinant human erythropoietin therapy].
abstract: The major problems in liquid storage of donated blood are the limitation of blood volume preserved and the time consumed. We studied on the usefulness of utilization of recombinant human erythropoietin (rH-EPO) for preoperative collection of autologous blood. Patients were divided into 2 groups: Group 1 (12 patients) received 3000 unit of rH-EPO intravenously every day. Group 2 (10 patients) was not treated with rH-EPO. All the patients were given ferrous sulfate 100 mg of iron orally every day. As a rule, 400 ml blood was donated two or three times a week for rH-EPO treated group, while, for control group 400 ml blood was collected once a week. Some patients did not donate 400 ml because of their critical condition. The blood volume preserved became 780.9 +/- 284.1 ml in Group 1, and 910.8 +/- 263.9 ml in Group 2. However, the number of days until operation were significantly shorter in Group 1 (8.7 +/- 3.6 days) than in Group 2 (26.2 +/- 11.2 days). Hemoglobin and Hematocrit levels recovered promptly in rH-EPO treated group. In control group, 2 patients complained of nausea and vomiting caused by severe anemia. On the other hand, no one with rH-EPO therapy did not show any side effects and complications. Our study indicates that the administration of rH-EPO enables us to collect an adequate volume of autologous blood preoperatively in a shorter period of time.
