摘要
目的深入研究退休矿工肺通气功能的损害情况。方法本文对某镍矿45名退休矿工、37名离尘后定诊矽肺患者和40名对照矿工的肺通气功能进行了 14年的追踪与配对追踪观察。结果退休矿工 FVC、FEV1的年均下降值显著大于对照矿工,除配对追踪观察中的FVC外,其差别均有显著意义(P<0.05);矽肺患者FVC、FEV1的平均下降值也较对照矿工为高,但除配对追踪观察中的FEV1外,其差别均无统计意义。FVC、FEV1异常率的增高,以退休矿工最高,矽肺患者次之,对照矿工最小,其中退休矿工FEV1异常率的增加值与对照矿工相比差异显著。结论长期接触高浓度的矽尘,矿工退休离尘后肺通气功能仍在丧失,损害的严重程度可与矽肺患者相比。
Objective To study on the changes of the pulmonary function of silicotic patients and retired nickel miners who had ben exposed to dust for a long time during their employment. Methods General and matched follow-up pulmonary function studies lasting for 14 year were performed on 45 retired nickel miners, 37 silicotic patients and 42 control workers. Results Both follow-up analysis showed that the annual decrements in force vital capacity (FVC) and force expiratory volume in one second (FEV1) were statistically significant (except for FVC in matched study), they the showed that the annual FVC and FEV1 decreases in the silicosis group were slightly greater than those in the control group and that the differences had no statistical significance (except for FEV1 in matched study), it had also been found that the elevation of abnormal rates in FVC and FEV1 in the retired group were the highest among that of three groups, with the silicosis group and the control group showing the second highest and the lowest elevations respectively, and that the elevation of abnormal rates in FEV1 were significantly different between the retired group and the control group. Conclusion The results indicated that there was lung function loss in the retired miners and the silicotic patients, and the injury of the retired workers seemed to be serious.
