支气管镜并支气管肺泡灌洗术(BAL)已广泛用于研究各种肺部疾病。为了评价BAL对人肺的影响,作者对37例正常健康人进行了重复支气管镜检及BAL。对象和方法37例健康受检者平均年龄35岁,男23例,女14例,分为6组。组1～4受检者分别于第一次BAL后2、7、24、72小时行第二次BAL;组5系在全麻开始和结束时行两次BAL,此时支气管镜配有气管内套管以除外口腔内容物吸入或局麻药的影响;组6为对照组,第一次只进行支气管镜检而不行BAL,7小时后同时行支气管镜检及BAL。支气管镜下支
Bronchoscopy and bronchoalveolar lavage (BAL) have been widely used to study various lung diseases. In order to evaluate the effects of BAL on human lungs, the authors performed repeated bronchoscopy and BAL on 37 normal healthy subjects. Subjects and methods 37 healthy subjects average age 35 years old, 23 males and 14 females, divided into 6 groups. Groups 1 to 4 subjects received the second BAL at 2, 7, 24, and 72 hours after the first BAL, respectively. Group 5 received BAL twice at the beginning and at the end of general anesthesia. The bronchoscope was equipped with a trachea Group C was the control group, the first time only bronchoscopy and not BAL, 7 hours after bronchoscopy and BAL. Bronchoscopy branch
