Abstract

Objective: Preoperative anemia is a major risk factor for perioperative transfusion in orthopedic surgery and aging is associated with an increased risk for developing anemia. The aim of this study was to compare the efficacy and safety of preoperative epoetin alfa in patients older and younger than 65 years in orthopedic surgery. PATIENTS AHD METHOD: This study involved 75 patients scheduled for total joint arthroplasty who had an hemoglobin level between 100 and 130 g/l. Patients were assigned to receive weekly doses of subcutaneous epoetin alfa (40000 IU) on days -21, -14, -7, -1 before surgery. We tabulated age, weight, gender, baseline analytic parameters, perioperative evolution of the mean hemoglobin level, transfusion, side effects and complications.

Results: Fifty-four patients were included in group A (> or = 65 years) and 21 in group B (< 65 years). The two study groups did not differ in terms of demographic characteristics and baseline analysis but differed in age and associated diseases. The preoperative increase in mean hemoglobin level (20 and 18 g/l) and transfusion rate (15% and 14.3%) were similar in both groups. There were no complications associated with the use of epoetin alfa.

Conclusions: Preoperative epoetin alfa administration seems to be as effective and safe in patients younger as in those older than 65 years.
