Background. Various blood management strategies can be used to reduce the need for allogeneic blood in cardiac surgery. In anemic patients, however, avoidance of allogeneic blood transfusion is difficult to achieve. This study was performed to assess the safety and effectiveness of preoperative blood collection using recombinant human erythropoietin (rHuEPO) for reducing the exposure to allogeneic blood in anemic patients.
Methods. Thirty-two anemic patients undergoing cardiac surgery at our hospital between January 1994 and October 1997 were divided into two groups according to preoperative strategies: 3-week treatment with rHuEPO and blood donation (group 1, n = 16) or iron supplementation alone (group 2, n = 16).
Results. There were no statistically significant differences between the two groups in patients’ characteristics and surgical data. The number of reticulocytes was increased at just before surgery in group 1, whereas group 2 showed no significant increase. The estimated hemoglobin increases in group 1 were higher at 7 days and just before surgery. The mean number of required allogeneic blood for patients during surgery was 0.59 ± 1.12 U in group 1 and 5.01 ± 2.63 U in group 2. In 75% of group 1 patients, allogeneic blood transfusion was successfully avoided, whereas all patients in group 2 received allogeneic blood.
Conclusions. This study suggests that the combination of rHuEPO administration and autologous blood donation can reduce the need for allogeneic blood in anemic patients.
