[Autologous blood donation with recombinant human erythropoietin prior to elective cardiac surgery in anemic patients].
Despite the reducing exposure to allogeneic blood in cardiac surgery, most of patients with anemia still require allogeneic blood. In this study, we have attempted to harvest the blood from cardiac patients with baseline hemoglobin levels below 11.0 g/dl using recombinant human erythropoietin (rHuEPO). 29 anemic patients undergoing cardiac surgery at our hospital between January 1994 and March 1997 were divided into two groups: 3 weeks' treatment with recombinant human erythropoietin (rHuEPO) and blood donation (group 1, n = 15) and iron supplementation alone (group 2, n = 14). There were no statistically significant differences among the two groups in patients characteristic and surgical data. No serious adverse events after phlebotomy were apparent in patients donating autologous blood. Patients in group 1 had significantly higher hemoglobin levels than patients in group 2 at 7 days before operation. The number of reticulocytes were increased at just before operation in group 1, whereas group 2 showed no significant increase. The estimated hemoglobin increase in group 1 were higher at 7 days and just before operation. In 75% of group 1, allogeneic blood transfusion could be avoided, while all patients in group 2 received allogeneic blood transfusion. This study suggests that the combination of rHuEPO administration and autologous blood donation would be beneficial for anemic patients in elective cardiac surgery. The use of rHuEPO should not be restricted to anemic patients.
