本文对195例矽肺病人和104例健康工人的小气道功能进行了研究。两组测得值经统计学处理,结果表明:Ⅰ期矽肺病人的小气道功能测得值比健康工人为低,其差异有非常显著意义(p<0.01),且随着病期进展而明显;又证实在Ⅰ期矽肺病人中,大、小气道异常率分别为23.8％、52.3％,相差28.5％,P<0.01,且大气道功能正常的病人小气道功能测得值亦低于对照组。提示小气道功能测定方法在早期矽肺病人中比大气道功能测定方法敏感。故认为,小气道功能测得值可做为矽肺病人劳动能力鉴定参数之一。
In this article, we studied the small airway function in 195 patients with silicosis and 104 healthy workers. The measured values of the two groups were statistically analyzed. The results showed that the small airway function of stage I patients with silicosis was lower than that of healthy workers, and the difference was statistically significant (p <0.01), with a significant increase as the disease progressed ; And confirmed that in patients with stage I silicosis, the abnormal rates of large and small airways were 23.8%, 52.3%, a difference of 28.5%, P <0.01, and the small airway function measured in patients with normal airway function was also lower than the control group . Tip Small airway function assay is more sensitive than airway function test in early silicosis patients. Therefore, the measured value of small airway function can be used as one of the identification parameters of the ability of silicosis patients.
