肺结核是矽肺最常见的合并症之一,也是引起矽肺患者死亡的主要原因。因此,开展矽肺防痨,努力减少矽肺结核的发生,延长矽肺病人的寿命,是我们职防工作者的主要任务之一。 防痨之必要性 矽肺结核并发率,可随患者接触粉尘的种类不同而有所不向。粉尘中游离二氧化矽硅量愈高,矽肺结核的并发率愈高。据调查,接触石英粉尘的矽肺患者,其结核并发率约占70～80％,而接触其它粉尘(游离二氧化硅含量在50～30％时)其并发率为50％,当所接触的粉尘的含矽量低于30％时则降为20％。各类尘肺结
Tuberculosis is one of the commonest comorbid silicosis and the leading cause of death in silicosis patients. Therefore, it is one of the major tasks of our defense workers to carry out prevention of silicosis and strive to reduce the incidence of silicosis and extend the life of silicosis patients. Necessity of prevention of silicosis The incidence of silicosis, with the type of contact with the dust of different people do not. The higher the amount of free silica in the dust, the higher the incidence of silicosis. According to the survey, silicosis patients exposed to quartz dust, the incidence of tuberculosis accounted for about 70 to 80%, and contact with other dust (free silica content of 50 to 30%) the incidence of 50%, when the dust When the silicon content is less than 30%, it drops to 20%.
