Objective  To investigate the effectiveness of recombinant human erythropoietin (rHuEPO) combined with iron in treatment of anemia in elderly patients with intertrochanteric fractures during perioperative period. Methods  A clinical data of 71 patients with intertrochanteric fractures met the inclusion criteria between April 2016 and October 2017 was retrospectively analyzed. All patients were treated with closed reduction and proximal femoral intramedullary nail fixation. Thirty-one patients were treated with rHuEPO and iron before operation as trial group, and 40 patients were not treated with rHuEPO and iron as control group. There was no significant difference in gender, age, body mass index, cause of injury, fracture side and classification, American Society of Anesthesiologists (ASA) classification, combined medical diseases, time from fracture to admission, preoperative hospital stay, and operation time between the two groups (P>0.05).The hemoglobin levels before operation and at 1, 3, and 7 days after operation, number of blood transfusion, blood transfusion rate, blood transfusion volume, postoperative hospital stay, complications were recorded and compared. Results  After operation, 8 patients (25.8%) in trial group and 22 patients (55.0%) in control group received blood transfusion; the blood transfusion volume was (1.96±0.85) units in trial group and (3.19±1.61) units in control group. There were significant differences in blood transfusion rate and volume between the two groups (P<0.05). There was no significant difference in preoperative hemoglobin level between the two groups (P>0.05). The postoperative hemoglobin level was higher in trial group than in control group, and the difference between the two groups was significant at 7 days (P<0.05). The postoperative hospital stay was (6.16±3.97) days in trial group and (9.25±4.47) days in control group, showing significant difference between the two groups (P<0.05). There were 8 patients (25.8%) with pulmonary infection in trial group and 14 (35.0%) in control group after operation; 6 patients (19.4%) with deep venous thrombosis in trial group and 8 (20.0%) in control group. There was no significant difference in the incidences of complications between the two groups (P>0.05). All patients were discharged from hospital normally, and no one died during hospitalization. Conclusion  The application of rHuEPO combined with iron before operation in elderly patients with intertrochanteric fractures can rapidly increase the hemoglobin level after operation, shorten the hospital stay, and do not increase the risk of deep venous thrombosis after operation.
