目的:了解某煤矿矽肺病人肺功能损害情况,探讨接尘对肺功能的影响。方法:以2011年6月~2012年6月在我矿局职防所进行职业健康体检的200名煤矿矿工为研究对象,其中113例无矽肺,即为对照组,87例有矽肺,即为观察组,对两组FVC、MVV等相关指标进行测定,分析矽肺患者肺功能损害情况。结果:观察组87例矽肺患者中,肺通气功能轻度损伤26例(占29.9%),中度损伤47例(54.0%),重度损伤14例(16.1%),对照组113例肺通气功能均正常。同时,观察组FEV1、FVC、FEV1%、MMF、MVV、V25、V50、Vmax各项肺通气功能指标均显著低于对照组(P<0.05),均具有统计学意义。结论:由于长期接触高浓度的生产性粉尘,矽肺病人肺功能损害明显,肺通气功能的检测为临床诊断矽肺提供了有力的参考依据,煤矿工人也应注意肺功能的监护。
Objective: To understand the damage of lung function in silicosis patients in a coal mine and explore the effect of dust exposure on lung function. Methods: Totally 200 miners who took part in occupational health examination at our mine prevention and control office from June 2011 to June 2012 were selected as research objects. 113 of them were without silicosis, which was the control group. 87 patients had silicosis The observation group, the two groups of FVC, MVV and other related indicators were measured to analyze the lung function of patients with silicosis damage. Results: Among the 87 patients with silicosis, 26 patients (29.9%) had moderate pulmonary ventilation, 47 patients (54.0%) had moderate injury, and 14 patients (16.1%) had severe injury. In the control group, 113 patients had pulmonary ventilation All normal. At the same time, pulmonary function indexes of FEV1, FVC, FEV1%, MMF, MVV, V25, V50 and Vmax in the observation group were significantly lower than those in the control group (P <0.05), all of which were statistically significant. Conclusion: Due to long-term exposure to high concentrations of productive dust, pulmonary function impairment in patients with silicosis is obvious. The detection of pulmonary ventilation provides a powerful reference for the clinical diagnosis of silicosis. Coal miners should pay attention to the monitoring of pulmonary function.
