陈廷桂、黄燕萍、马秀荣(徐州矿务局职防院)报道:本文对55例煤工尘肺的肺弥散功能作了观察。结果表明:合并慢性支气管炎(慢支)与不合并慢支之间肺通气功能与弥散功能均见明显差异(P<0.05)。在不合并慢支的各组之间,仅煤工尘肺0、0~+期(入院前诊断Ⅰ期,但用新标准复诊为0或0~+)与Ⅰ、Ⅱ期煤工尘肺间的一氧化碳弥散量(Tco)预期值(%)的X±S,有显著性差异 Chen Tinggui, Huang Yanping, Ma Xiurong (Xuzhou Mines Prevention and Control Bureau) reported: 55 cases of coal workers pneumoconiosis pulmonary diffuse function was observed. The results showed that pulmonary ventilation and diffuse function were significantly different between chronic bronchitis (chronic bronchitis) and chronic bronchitis (p <0.05). Between the groups without chronic bronchitis, only coal workers with pneumoconiosis 0,0 ~ + (pre-hospital diagnosis of stage Ⅰ, but with the new standard referral 0 or 0 ~ +) and Ⅰ, Ⅱ coal workers pneumoconiosis There was a significant difference in the X ± S of expected value (%) of carbon monoxide dispersion (TCO)
