煤矽肺肺气肿,是由于慢性阻塞而引起的有病理性改变的肺泡过度充气。对于肺气肿的分度,在肺功能测定上多采用Motley氏的四级分度法;卫生部制订的“矽尘作业工人医疗预防措施实施办法”中,则把矽肺患者的代偿机能分为甲、乙、丙三类;我们认为肺气肿的分度按轻、中、重三级划分较为切合实用。为了进一步探讨煤矿矽肺肺气肿的分度,我们于1978～1979年在坊子煤矿选择了80例煤矿矽肺,并从病史、症状、体征、胸部X线片及肺功能测定等证明确系肺气肿患者作为研究对象,结合文献资料和我们在此项工作中的体会,提出了一个三度肺气肿的分度指标,然后从每一项的最大应用效能出发,逐项加以分析探讨。我们初步设想的三度肺气肿诊断指标如 Coal silicosis emphysema, is due to chronic obstruction caused by pathological alveolar hyperventilation. For the degree of emphysema, lung function test using Motley’s fourth-degree indexing; the Ministry of Health to develop “Silica dust workers in the implementation of medical precautionary measures”, the silicosis patients compensation function points For the A, B, C three categories; we think that the division of emphysema according to light, medium and heavy three more appropriate classification. In order to further discuss the indexing of silicotic pulmonary emphysema in coal mines, we selected 80 cases of silicosis in Fangzi Coal Mine from 1978 to 1979 and confirmed the lungs from history, symptoms, signs, chest radiographs and pulmonary function tests Patients with emphysema as the research object, combined with the literature and our experience in this work, proposed a three degree emphysema indexing, and then from each of the maximum application efficiency, one by one to be analyzed and discussed. We initially envision a third degree emphysema diagnostic indicator such as
