Objectives: The aim of this study was to define whether growth hormone therapy would reduce the course of postoperative fatigue (POF) in aged patients (60～80 years old) with nutritional support. Methods: Forty aged patients who underwent partial gastrectomy or other operations were randomized into two groups. All patients were treated with the same nutritional support formula.A group of patients was treated with rhGH for 7 day from the third day after operation, and control group treated with placebo.The score of POF, nitrogen balance, transferrin level and body weight were monitored. Results: Score of POF in rhGH group on day 7 and 14 after operation was lower than that in control group(P0.05). Conclusions: Aged patients with rhGH after major operation can recover more rapidly from POF.
