Age, body weight, smoking, chronic bronchitis and duration of anaesthesia were assessed as risk factors for respiratory complications following surgery for peptic ulcer or gallbladder disease. The studies were made on 53 men aged 40-75 years. All variables were associated with increased postoperative risk of chest X-ray abnormality or arterial hypoxaemia or clinically overt respiratory complications. In the statistical analysis, however, none of the factors proved to be useful as a predictor of postoperative respiratory complications. The observed high frequencies of X-ray abnormalities (54%) and arterial hypoxaemia (43%) after operation indicate potential dangers. They may be reduced by cessation of smoking before the operation and reduction of weight.
对年龄、体重、吸烟、慢性支气管炎和麻醉持续时间作为消化性溃疡或胆囊疾病手术后呼吸并发症的危险因素进行了评估。研究对象为53名年龄在40 - 75岁的男性。所有变量均与术后胸部X光异常、动脉血氧不足或临床明显呼吸并发症的风险增加相关。然而，在统计分析中，没有一个因素被证明可作为术后呼吸并发症的预测指标。术后观察到的X光异常（54%）和动脉血氧不足（43%）的高发生率表明存在潜在危险。术前戒烟和减轻体重可能会降低这些风险。
