目的探讨疑似煤工尘肺的肺功能状况。方法随机抽取2007-2008年10个煤矿的全部职业健康检查资料共计1042份,其中有疑似煤工尘肺82例,并对疑似煤工尘肺的肺功能测定指标进行分析。结果疑似煤工尘肺的肺功能基本上表现异常(r=0.51,P<0.005),且疑似煤工尘肺的进程与肺功能状况明显相关(r=0.50,P<0.005)。结论粉尘类作业职业健康体检,采用肺功能测定结果作为疑似煤工尘肺初筛和阅片的指导具有一定意义。
Objective To investigate the pulmonary function of suspected coal worker’s pneumoconiosis. Methods A total of 1 042 occupational health examinations were randomly selected from 10 coal mines from 2007 to 2008, of which 82 were suspected coal workers’ pneumoconiosis. The lung function of suspected coal worker pneumoconiosis was analyzed. Results The lung function of suspected coal worker pneumoconiosis was basically abnormal (r = 0.51, P <0.005), and the process of suspected coal worker pneumoconiosis was significantly correlated with pulmonary function status (r = 0.50, P <0.005). Conclusion Dust class occupational health examination, the use of pulmonary function test results as suspected coal workers pneumoconiosis screening and reading guidance is of some significance.
