目的探讨某金矿矽肺患者胸部X射线片动态变化的规律。方法连续观察5年在本院住院的金矿矽肺患者33例,每年于入院、出院时拍摄高千伏胸部X射线片各1张,胸部X射线片由2名尘肺病诊断医师阅片诊断。结果金矿矽肺5年晋期率为24.24%,平均晋期年限为(2.20±1.09)年;有6例矽肺合并结核患者发展成难治性肺结核,5年间新增9例(27.27%)矽肺合并结核患者;5年后合并慢性支气管炎、肺气肿、胸膜增厚粘连率较5年前明显增多(P<0.05);5年间出现毁损肺12例(36.36%)。结论金矿矽肺晋期年限短,合并肺结核率高,易出现难治性肺结核,矽肺合并症较多,短期内出现毁损肺。
Objective To investigate the regularity of dynamic changes of chest X-ray film in silicosis patients in a gold mine. Methods Thirty-three patients with silicosis of gold mine who were hospitalized in our hospital for 5 years were continuously observed. One high kilovolt chest X-ray film was taken at admission and discharged each year. The chest X-ray film was diagnosed by two pneumoconiosis physicians. Results The rate of silicosis of gold mine in 5 years was 24.24%, and the average age of promotion was (2.20 ± 1.09) years. Six patients with silicosis complicated with tuberculosis developed refractory pulmonary tuberculosis, and 9 cases (27.27%) newly added silicosis 5 years after the merger of chronic bronchitis, emphysema, pleural thickening adhesion rate was significantly increased compared with 5 years ago (P <0.05); 12 cases of lung damage occurred in 5 years (36.36%). Conclusion The silicosis of silicosis of gold mine is short, with high incidence of pulmonary tuberculosis, refractory tuberculosis and silicosis.
