ANALYSIS OF THE DEAD CASES OF SILICOSIS

[Objective]To discuss the developmental rule and to forecast the developmental trend of silicosis.[Methods]A retrospective analysis was carried out to 525 dead cases in Xinjiang railroad bureau from 1970 to 2006.The combinational symptoms,the destroy degree and the dysfuction of lung function were analyzed concretely.[Results]The combinational symptoms were brought considerably in the dead cases of silicosis.The extent of lung funtion destroy in the first grade silicosis was in the middle,but the extents of lung funtion destroy in the second and third grade silicosis were severe.The first grade silicosis had mainly obstructive ventilatory impairment and mixed ventilatory impairment,whereas the second and third grade silicosis had restrictive ventilatory impairment and mixed ventilatory impairment.[Conclusion]The combinational symptoms of the silicosis patients should be prevented and treated immediately.The examination of lung funtion is necessary so that we can observe the changes of the development of silicosis and identify the working ability of these patients.
