Effects of recombinant erythropoietin on hemoglobin levels and blood transfusion needs in patients with preoperative anemia undergoing cardiac surgery

Abstract

Introduction: Preoperative anemia is an important and relatively common problem in patients undergoing cardiac surgery, and its treatment is crucial in improving postoperative outcomes. The use of recombinant erythropoietin is one of the suggested methods in this field. Therefore, in the present study, we sought to evaluate the effects of recombinant erythropoietin on hemoglobin (Hb) levels and blood transfusion needs in cardiac surgery in patients with preoperative anemia. Methods: This randomized nonblind clinical trial was performed on patients with mild-to-moderate anemia (Hb 0.05), showed a significantly lower decrease in the intervention group (P = 0.001). No significant differences were observed concerning other variables. Conclusions: The use of recombinant erythropoietin (500 IU/kg/day) one to three days before cardiac surgery in our anemic patients blunted a reduction in Hb levels and decreased blood transfusion needs.
