【摘要】 本文应用寿命表统计法,通过累计存活率和稳定率,对合山矿务局二十七年来确诊的491例尘肺进行动态观察,从纵面剖析该局煤矽肺检出和调离接尘作业后的发展规律,获得了下列有意义的信息:(一)按照本文寿命表法推算,调离粉尘作业的患者经30年后,存活率为61%,而病情稳定率为34%,说明有一部份患者的病情仍然不断地进展恶化.(二)从本文寿命表统计法看到,无论任何年度,初诊Ⅰ期患者累计存活率均最高,其次是初诊Ⅱ期,而初诊Ⅲ期者最低,说明了煤矿尘肺的早期诊断和早期脱离粉尘作业有重要意义.(三)从本文寿命表统计法来看,一是要加强防尘工作,实施一级预防;二是要早期诊断,早期脱离粉尘作业,并每年追踪拍照一张质量优良的X线胸片,以利于保护煤矽肺患者的健康和实施二级预防的观察.更多还原

【Abstract】 491 pneumoconiotic patients found in Hashan Coal Mine Bureau were continually followed up in the past 27 years with the aid of life table method, accumulating the survival and stability rate among them. The following results were obtained by analysis of the incidence of pneumoconiotics in the Bureau. (1) The survival rate among the patients, who had been freed from the coal-dust-polluted environment for 30 years, was 61%, but the stability rate was 34%, This indicated that the health of part of the patients became worse. (2) The accumulated survival rate of stage I patients was the highest in any year of the follow up, but that of stage 3 patients was the lowest, and that of stage 2 was in between. Naturally, it is important for the patients to be early detected and freed from the coal dust-polluted environment as early as possible. (3) The data available suggest 1)to stress preventive measures to control coal dust pollution, and 2)to make early diagnosis of pneumoconiotics and free them from the dust-polluted environment. It is necessary to carry out grade Ⅱpreventive measures, including an annual reliable chest X-ray examination of the patients for the sake of their health.更多还原
