Pulmonary auscultation, pulmonary function tests and radiological examination were done in 127 hospitalized patients with silicosis. Fine crackle (FC) was heard in 21.3% of patients, coarse crackle (CC) in 28.5%, rhonchi or wheeze (RorW) in 25.2% and friction rub (FR) in 5.5%. In complicated silicosis the incidence of rales was paradoxically lower than in simple silicosis (54.6 vs. 83.3%, respectively, p less than 0.05). In simple silicosis, patients with CC and/or RorW had lower %VC and FEV1/FVC%, but in complicated silicosis, the relation between the presence of rales and pulmonary functional status was not so apparent. These results suggest that in relatively advanced silicosis, all kinds of rales are heard, and in simple silicosis, rales are useful indicators of physiological impairment, but in complicated silicosis, they do not seem to be so useful.
对127例住院矽肺患者进行了肺部听诊、肺功能检查和影像学检查。21.3%的患者可闻及细湿啰音（FC），28.5%可闻及粗湿啰音（CC），25.2%可闻及干啰音或哮鸣音（RorW），5.5%可闻及胸膜摩擦音（FR）。在复杂矽肺中，啰音的发生率反而低于单纯矽肺（分别为54.6%和83.3%，p<0.05）。在单纯矽肺中，有CC和/或RorW的患者%VC和FEV1/FVC%较低，但在复杂矽肺中，啰音的存在与肺功能状态之间的关系并不明显。这些结果表明，在相对晚期的矽肺中，可闻及各种啰音，在单纯矽肺中，啰音是生理损害的有用指标，但在复杂矽肺中，它们似乎不那么有用。
