title: Subcutaneous use of erythropoietin in heart surgery.
abstract: The effect of subcutaneous administration of recombinant human erythropoietin (rHuEPO) in ameliorating anemia resulting from autologous blood donation was compared with intravenous administration of rHuEPO. Forty patients undergoing coronary artery bypass procedures were divided into three groups. Group I (12 patients) received intravenous administration of rHuEPO (100 U.kg-1.day-1) and intravenous iron preparations for 14 days before operation; group II (14 patients) had subcutaneous administration of rHuEPO (600 U/kg) on preoperative days 14 and 7 and oral iron preparations for 14 days; and group III (14 patients) received oral iron preparations alone and served as the controls. Each patient predonated 800 mL of blood in the 2 weeks before operation. The reticulocyte count increased significantly in groups I and II (p less than 0.01), but little in group III. The hemoglobin level just before operation was higher in groups I (p less than 0.01) and II (p less than 0.05) compared with group III. Four patients (29%) in group III required homologous blood transfusion versus none in groups I and II (p less than 0.05). Subcutaneous administration of rHuEPO once a week was as effective as daily intravenous administration. Preoperative autologous blood donation can be performed over a short period on an outpatient basis with subcutaneous administration of rHuEPO.
