摘要
目的探讨尘肺分期与肺功能的关系。方法采用肺功能测试仪测定爆破工矽肺患者用力肺活量(FVC),一秒钟用力呼气量(FEV1),一秒钟用力呼气量与用力肺活力量比值(FEV1%)。结果 94例患者中,肺功能异常59例,占62.8%。Ⅲ期矽肺患者肺损伤例数和程度均明显高于Ⅰ、Ⅱ期,各期比较,差异有统计学意义。矽肺患者肺功能损伤以限制型和单纯FEV1下降比例最高。结论矽肺患者随矽肺期别增高,其肺功能损伤严重程度和发生率增加,尤其以Ⅲ期患者为著。该文中矽肺患者肺功能损伤以限制型和单纯FEV1下降为主,对于单纯FEV1下降患者建议进行肺弥散功能以及其他肺功能指标检测。
[Objective]To study the relationship between pulmonary function and staging silicosis. [Methods]Pulmonary function test instrument was used to measure FVC,FEV1,FEV1% of blaster with silicosis. [Results]Of 94 patients,59（62.8%） had abnormal pulmonary function.The case numbers and degree of abnormal pulmonary function in stage Ⅲ were higher than those of stage Ⅰ or Ⅱ,the difference between each stage was significant.The restrictive and FEV1 abnormal fall were more easily to observe in pulmonary function damage of Silicosis. [Conclusion]The severity and incidence of pulmonary function damage increases with the advancing of silicosis stage,especially for the patients with silicosis stageⅢ. The restrictive and FEV1 abnormal fall of pulmonary function damage were observed easily in this study.The silicosis patients with only FEV1 fall are advised to receive pulmonary diffusion function and other pulmonary function test.
