Abstract
Background: Preoperative anemia is an independent risk factor for higher rates of blood transfusion in cardiac surgery. This study aimed to evaluate the effects of intravenous iron sucrose and erythropoietin on transfusion requirements in patients with preoperative iron deficiency anemia (IDA) undergoing on-pump coronary artery bypass graft (CABG) surgery. Methods: In this open-label, randomized clinical trial, patients with preoperative IDA who were candidates for on-pump CABG were randomized into intervention (iron plus erythropoietin) or control groups. Iron sucrose was administered as a 200 mg intravenous dose and erythropoietin as a 100 IU/kg bolus 1 to 2 days before surgery. The primary outcome was the amount of blood transfusion during the first 4 postoperative days. Results: The study population consisted of 114 patients. The mean age was 64.11±8.18 years in the intervention group and 63.35±8.70 years in the control group. Twenty-seven patients (47.4%) in the intervention group and 25 (43.9%) in the control group were males. The number of red blood cell units transfused per patient exhibited a significant fall in the intervention group compared with the control group (P˂0.001). The ferritin level showed a significant rise in the intervention group on postoperative day 7 (P=0.027). The length of stay in the intensive care unit and the hospital was significantly lower in the intervention arm (P=0.041 and P=0.006, respectively). No adverse events were reported in both groups. Conclusion: The use of erythropoietin and iron sucrose 1 to 2 days before surgery significantly decreased the need for blood transfusion in patients with IDA undergoing CABG without any significant adverse events.
