本文以110例矽肺病人和103例接触矽尘时间较长的工人为对象,对矽肺病人肺功能损害程度及特点进行了研究。结果表明:矽肺病人组各通气功能指标和弥散量都明显低于接尘工人组(P<0.01)。各期矽肺病人比较,各项肺功能指标均随矽肺期别的增加而降低。分析肺功能损害的性质表明,矽肺病人主要表现为混合性和阻塞性损害。
In this paper, 110 patients with silicosis and 103 workers exposed to silica dust for a long time as the object, the extent and features of pulmonary function impairment in patients with silicosis were studied. The results showed that the index of ventilatory function and the amount of diffusing capacity in patients with silicosis were significantly lower than those in dust-exposed workers (P <0.01). All patients with silicosis, the lung function indicators are increased with the addition of other silicosis decreased. Analysis of the nature of pulmonary function damage shows that the main manifestations of silicosis are mixed and obstructive lesions.
