不少学者认为慢性严重难以解释的咳嗽,是仅次于咳血需作支气管镜检查(以下简称支镜)的指征之一,尤其是年龄>40岁而胸片正常者作支镜以早期诊断肺癌。为了考察这一看法的科学性,本文回顾性研究单独慢性咳嗽患者利用支镜及其它检查方法在确定咳嗽病因上的价值。109例年龄15～89岁,男性68例,女性41例;皆仅有慢性咳嗽症状达2个月以上,无咳血,既往无慢性呼吸道病史或哮喘史,胸片正常或与以前胸片所示病变无改变。有34例吸烟,22侧已戒烟,53例不吸烟。51例作支镜,49例作肺功能检查。最后确诊与咳嗽有关的疾病以哮喘最多39例(36%),其中23例不吸烟,有14例经吸入碳酰胆碱示肺功能异常,给支气管舒张剂治疗后,咳嗽即改善或消失。27例(25%)为病
Many scholars believe that chronic and difficult to explain the cough, is second only to hemoptysis bronchoscopy is required (hereinafter referred to as bronchoscopy) one of the indications, especially those aged> 40 years old with normal chest X-ray as an early diagnosis Lung cancer. In order to examine the scientific nature of this view, we retrospectively studied the value of using bronchoscopy and other tests in determining the etiology of cough in patients with chronic cough. 109 patients aged 15 to 89 years, 68 males and 41 females; only chronic cough symptoms for more than 2 months, no hemoptysis, no previous history of chronic respiratory disease or asthma, chest X-ray normal or with the previous chest X-ray No change in lesions. There are 34 cases of smoking, 22 side has quit smoking, 53 cases of non-smoking. 51 cases of bronchoscopy, 49 cases of pulmonary function tests. The final diagnosis of cough-related diseases with asthma up to 39 cases (36%), of which 23 were not smokers, 14 cases of pulmonary dysfunction by inhalation of carbachol to bronchodilator treatment, the cough that is improved or disappeared. 27 cases (25%) were sick
