【摘要】：目的探討煤礦掘進(jìn)工累積接塵劑量與肺功能累計異常率的關(guān)系。方法 2014年12月—2015年12月選取唐山某煤礦掘進(jìn)工376例為觀察組,非接塵工179例為對照組,均行肺功能[用力肺活量(FVC),第1秒用力呼氣末容積(FEV_1),FEV_1/FVC]檢測。觀察組每隔10年為1個接塵工齡組,分為10年、10~年、20~年、30~年工齡組。比較對照組和觀察組及各接塵工齡組間的肺功能,分析累積接塵劑量與肺功能累計異常率的關(guān)系。結(jié)果觀察組肺功能異常率(51.6%,194/376)高于對照組(12.8%,23/179)(P0.05)。觀察組FVC、FEV_1、FEV_1/FVC低于對照組(P0.05)。10~年工齡組FVC、FEV_1、FEV_1/FVC低于10年工齡組(P0.05)。20~年工齡組FVC、FEV_1、FEV_1/FVC低于10年工齡組和10~年工齡組(P0.05)。30~年工齡組FVC、FEV_1、FEV_1/FVC低于10年工齡組、10~年工齡組、20~年工齡組(P0.05)。累積接塵劑量與肺功能累計異常率呈正相關(guān)(r=0.763,P0.001)。結(jié)論煤礦掘進(jìn)工累積接塵劑量與肺功能累計異常率存在正相關(guān)性。接塵工齡時間越長,累積接塵劑量越大,肺功能累計異常率越高,肺功能指標(biāo)改變越明顯。累積接塵劑量可用于預(yù)測煤礦掘進(jìn)工肺功能異常發(fā)病的危險性和高危人群。
[Abstract]:Objective to explore the relationship between cumulative dust exposure dose and cumulative abnormal rate of pulmonary function in coal miners. Methods 376 cases of coal mine excavators in Tangshan from December 2014 to December 2015 were selected as observation group and 179 cases as control group. All patients were examined with forced vital capacity (FV), forced expiratory end-expiratory volume (FEV) at the first second and FEV 1 / FVC (FEV 1 / FVC). The observation group was treated with dust exposure every 10 years. The lung function of control group, observation group and dust exposure group were compared. Results the abnormal rate of pulmonary function in the observation group was 51.6% higher than that in the control group (12.8 / 179). The observation group was lower than the control group in FEV _ 1 / FEV _ 1 / FVC _ (1 / FVC). The FVC FEV _ 1 / FVC / FEV _ 1 / FVC in the observation group was lower than that in the control group (P < 0.05). The FEV _ 1 / F _ (VC) in the observation group was lower than that in the control group (P < 0.05). The FEV _ 1 / F _ VC in the observation group was lower than that in the control group (P < 0.05). The FEV _ 1 / F _ (VC) in the observation group was lower than that in the control group (P < 0.05). The FEV1 / FVC in the observation group was lower than that in the control group (P < 0.05). The FVCU / FEV1 / FVC / FVC of 10 ~ 10 ~ 10 ~ 10 years of service group is lower than that of 10 ~ 10 ~ 10 ~ year working age group P0.05. The cumulative dust exposure dose is positively correlated with the cumulative abnormal rate of pulmonary function. Conclusion the cumulative dust exposure dose and lung work are positively correlated with the cumulative dust exposure dose of coal tunneling workers. There is a positive correlation in the cumulative abnormal rate. The longer the length of exposure to dust, The higher the cumulative dose of dust exposure, the higher the cumulative abnormal rate of pulmonary function and the more obvious the change of pulmonary function index. The cumulative dose of dust exposure can be used to predict the risk of abnormal pulmonary function of coal miners and high-risk population.
