目的:探讨木尘对接尘工人肺功能的急性影响。方法:运用T检验方法对某厂木型车间52名接触木尘工人肺功能进行了分析。结果:接尘组FVC、FEV1、MMF、V50与V25班中实测值均较班前明显降低,其差值具有非常显著的统计学意义。与对照组相比,接尘组肺功能各项指标的异常急性改变率显著增高(P均<0.01)。接尘组班前肺功能各项指标实测值占预计值百分比均较对照组明显降低,并具有非常显著的统计学意义。结论:木尘对接尘工人的肺功能可能有急性影响作用。
Objective: To investigate the acute effects of wood dust on lung function of workers exposed to dust. Methods: T tests were used to analyze the lung function of 52 workers exposed to wood dust in a wood workshop of a factory. Results: The measured values of FVC, FEV1, MMF, V50 and V25 in the dust collection group were significantly lower than those before the shift, and the difference was statistically significant. Compared with the control group, the abnormal acute change rate of various indexes of lung function in the dust exposure group was significantly higher (all P <0.01). The percentage of the measured value of each index of lung function in the group receiving dust before the shift was significantly lower than that of the control group, and had a very significant statistical significance. Conclusion: Dust may have an acute effect on lung function of workers exposed to dust.
