The incidence of postoperative chest X-ray abnormalities, arterial hypoxemia and clinically recorded pulmonary complications was studied in fifty-two 40-75-year-old men admitted for elective surgery for peptic ulcer or gallbladder disease. Twenty-eight (54%) patients had an abnormal chest X-ray and twenty-three (43%) arterial hypoxemia, whereas only four patients (8%) were identified with clinical signs and symptoms of respiratory complications. Forty-one patients (79%) were found with pulmonary complications by at least one of the three methods. Twelve patients had both an abnormal chest X-ray and arterial hypoxemia. Only two of these were identified with clinical signs indicating pulmonary complications. The great discrepancy between results based on clinical signs and symptoms noted in the patients' records and results based on postoperative chest X-ray and measurements of the arterial oxygen tension, respectively, should be of great importance when comparing the incidence of pulmonary complications after different forms of surgery and when assessing risk factors and clinical consequences of respiratory complications.
对52名因消化性溃疡或胆囊疾病择期手术入院的40 - 75岁男性患者，研究了术后胸部X线异常、动脉血氧不足及临床记录的肺部并发症的发生率。28例（54%）患者胸部X线异常，23例（43%）动脉血氧不足，而仅有4例患者（8%）出现呼吸系统并发症的临床体征和症状。通过三种方法中的至少一种，发现41例患者（79%）有肺部并发症。12例患者胸部X线异常且动脉血氧不足。其中只有2例有提示肺部并发症的临床体征。当比较不同手术方式后肺部并发症的发生率以及评估呼吸系统并发症的危险因素和临床后果时，患者记录中基于临床体征和症状的结果与分别基于术后胸部X线和动脉血氧张力测量结果之间的巨大差异应具有重要意义。
