晚发性矽肺是指脱离粉尘作业后,在相当长一个时期内发生的矽肺。我们于1968年起坚持每隔2年对脱尘工人进行一次X线胸片检查,对于连续胸片齐全、质量符合诊断要求的,经地区矽肺诊断小组确诊。1968—1983年在脱尘工人中共检出晚发性矽肺59例,占同时期接尘工人的7.1％,占全矿矽肺病人的13.7％。发病年龄41～71岁,平均51.1岁,均为男性工人。
Late silicosis refers to the silicosis that occurs after a considerable period of time from dusting. Since 1968, we insisted that we carry out an X-ray examination of dust-removing workers every two years. For patients with continuous chest radiography, the quality meets the diagnostic requirements, the diagnosis was made by the district silicosis diagnostic team. In 1968-1983, 59 cases of late silicosis were detected among dust-removing workers, accounting for 7.1% of the dust-collecting workers in the same period and 13.7% of the total silicosis patients. Age of onset 41 to 71 years old, average 51.1 years old, are male workers.
