摘要
本文对326名脱尘矿工和69名不接触尘毒的健康工人分别进行了肺通气功能测定,并对影响脱尘矿工肺通气功能损害的因素进行了分析,结果表明:无论是肺通气功能的实测值、实测值占预计值的百分比,还是肺通气功能的异常率,或是最大呼气流速容量曲线的比较分析,均显示脱尘矿工的肺通气功能损害较对照工人为严重。多因素分析结果表明:接尘起始年代、慢性支气管炎对脱尘工人肺通气功能损害的影响尤为明显。即接尘起始年代越早或有慢性支气管炎者肺通气功能损害越重。
Lung function tests were carried out and the factors influencing the impairment of lung function were analyzed on 326 miners with past dust exposure and 69 control subjects. The results showed that regardless the actual measurements,percentages of predicted lung function,abnormal rate of lung function or the maximum expiratory flow rate-volume curves,the impairment of lung function was more serious'in miners with past dust exposure than that of the controls. Multistepwise regression analysis indicated that initial years of dust exposure and chronic bronchitis have significant effects on lung function impairment in miners with past dust exposure. The earlier was the initial year of dust exposure,or the one ever suffered from bronchitis,the more serious will be the impairment.
