调离铸钢粉尘作业工人肺功能的研究
The Pulmonary function in ex-steel foundriers
【摘要】 本文对143名调离铸钢粉尘作业工人肺功能损害及呼吸系统症状阳性率与慢性支气管炎的患病率进行了研究,结果表明:无论吸烟与否,离尘组工人的 FVC1、FEV1.0、FEF25-75%、V75、V50及FEV1.0/FVC%等肺功能指标的实测值占预计值百分比均较对照组工人明显降低,肺功能异常率则显著增高,除个别指标外,其差别均有非常显著的意义。配对比较显示:离尘组工人肺功能各项指标的实测值显著低于对照组,异常率以及呼吸系统症状阳性离与慢性支气管炎的患病率则较对照组显著升高。
【Abstract】 Shenyang In a survey of 143 steel foundriers who had stoped exposing to dust for 10 years or so, pulmonary function,respiratory symptoms and chronic bron- chitics were investigated and found that all the indexes of pul- monary funtion(percent of predicted)included FVC,FEV1, FEF25-75%,V75 and V50 were lower significantly in ex-steel foundriers than those in control group,and the abnormal rates of lung function besides FEV1/FVC% showed much higher in ex-steel foundriers than did in control group significantly too. Matching analysis revealed that the measured values of lung function among ex-steel foundriers declined significantly and the abnormal rates of lung function,the prevalence of respira- tory symptoms and the indicence of chronic bronchitis in ex- steel foundriers increased significantly comparing with control group.
