    Abstract:
    Recombinant human erythropoietin (rHuEPO) was administered to 42 elective heart surgery patients, and the volume of autologous blood donated within the preoperative short period and effects of improving anemia by postoperative rHuEPO administration were studied. rHuEPO (100 U/kg/day) and chondroitin sulfate-iron (40 mg/day) were given intravenously for preoperative 14 days, and each 400 ml of autologous blood was donated on the 14th and 4th day before operation. Reticulocytes increased significantly 3 days after administration (p less than 0.01). The hemoglobin level, 13.4 +/- 1.0 g/dl before the first donation, returned to 13.4 +/- 1.1 g/dl just before operation. 800 ml of autologous blood, needed for usual open heart surgery, may possibly have been donated within 14 days without making patients anemic by intravenous rHuEPO administration. For postoperative rHuEPO administration, the patients were divided into 3 groups: Group I (10 cases): given for 14 days, Group II (12 cases): for 7 days, Group III (20 cases): no administration. Reticulocytes decreased rapidly after termination of rHuEPO administration in each group, and on the 7th day after termination, they returned to the level before administration. The hemoglobin level in Group I was maintained after termination of rHuEPO, and was +2.2 +/- 1.1 g/dl on the 21st postoperative day compared with the level of 1st postoperative day. The hemoglobin level in Group II fell after termination and was +0.9 +/- 0.7 g/dl on the 21st day, this being comparable to the level of Group III. There were significant differences between Group I and II (p less than 0.05), and between Group I and III (p less than 0.01).(ABSTRACT TRUNCATED AT 250 WORDS)
