矽肺是长期吸入含有游离二氧化硅的粉尘引起的,以肺部广泛的结节性纤维化为特征的疾患。长期吸入粉尘致使支气管纤毛上皮受到损伤,常并发慢性支气管炎进而导致阻塞性肺气肿,严重的发生肺心病。为了揭示矽肺合并症的发生发展,进一步加强矽肺病防治工作,延缓病情进展,现将我院1979～1998年400例住院矽肺患者的合并症统计分析如下:1 对象与方法
Silicosis is caused by prolonged inhalation of dust containing free silica, a condition characterized by extensive pulmonary nodular fibrosis. Long-term inhalation of dust caused by bronchial ciliated epithelium damage, often complicated by chronic bronchitis and then lead to obstructive pulmonary emphysema, severe pulmonary heart disease. In order to reveal the occurrence and development of silicosis, to further strengthen the prevention and treatment of silicosis, to delay the progression of the disease, now in our hospital from 1979 to 1998, 400 cases of hospitalized patients with silicosis were analyzed as follows: 1 objects and methods
