目的探讨煤粉尘对职业性接触人群肺功能和血液学常规的影响。方法用肺功能仪测定10项肺功能指标,全自动生化仪分析14项血常规指标,进行组间t检验分析。结果肺功能指标中接尘组所有测定指标均低于对照组,差异有显著性(P<0.05);血常规指标中除红细胞、血细胞压积、中性细胞比率和血小板分布宽度外,其余2组之间差异有显著性(P<0.05)。结论长期接触煤粉尘对职业性接触人群的肺通气功能有一定的损伤作用。
Objective To investigate the effect of coal dust on lung function and hematology in occupationally exposed population. Methods Pulmonary function test was used to measure 10 indexes of pulmonary function and 14 indexes of blood routine were analyzed by automatic biochemical analyzer. Results All the indexes of lung function index were lower than the control group, the difference was significant (P <0.05). In addition to the hematocrit, hematocrit, neutrophil ratio and platelet distribution, the remaining 2 There was significant difference between groups (P <0.05). CONCLUSIONS Long-term exposure to coal dust has a certain damaging effect on pulmonary ventilation in occupationally exposed populations.
