Abstract：Objective To investigate the influence of morbidly obesity on arterial oxygen partial pressure (PaO2) following gastric bypass surgery. Methods Preoperative lung function and blood gas analysis before and 1 to 5 days after abdominal surgery were performed on 61 morbidly obese patients and 55 patients with normal body weight. Results PaO2 first five days in obese group post-operatively and first 2 days after the surgery in control group were significantly lower than preoperative values(P＜0.05). PaO2 first two days after surgery in obese group was significantly correlated with maximal voluntary ventilation and waist-hip ratio (P＜0.000 1). Conclusion Postoperative hypoxaemia in morbidly obese patients following gastric bypass surgery is more severe and lasted longer than that in patients with normal body weight after selective abdominal surgery.
