We conducted a prospective study of 1,013 consecutive patients who were scheduled for elective surgery in Srinagarind Hospital to determine the prevalence of abnormal chest X-rays and the change in management. Chest X-ray abnormalities were detected in 19.4 per cent (181/933) and lead to management change in 3.6 per cent (34/933). Fifty out of 933 had tuberculosis like lesions and 59 had cardiomegaly. By using Mantel-Haenzel chi-square and logistic regression, age greater than or equal to 45 years old was the most important predictors of the abnormalities found. Other predictors were cough and productive sputum. There was no statistical difference of the intraoperative and postoperative complications among the patients aged less than 45 years who had normal and abnormal chest X-rays. A preoperative chest X-ray may be useful as a routine evaluation only in those aged greater than or equal to 45 years.
我们对1013例连续安排在诗里拉吉医院接受择期手术的患者进行了一项前瞻性研究，以确定胸部X光异常的患病率以及管理方式的变化。在933例患者中，有19.4%（181/933）检测出胸部X光异常，其中3.6%（34/933）的患者管理方式发生了改变。933例中有50例有结核样病变，59例有心脏扩大。通过使用Mantel-Haenzel卡方检验和逻辑回归分析，年龄大于或等于45岁是所发现异常的最重要预测因素。其他预测因素是咳嗽和咳痰。年龄小于45岁且胸部X光正常和异常的患者在术中和术后并发症方面无统计学差异。术前胸部X光检查可能仅对年龄大于或等于45岁的患者作为常规评估有用。
