尘肺继发气胸的临床观察

目的 总结尘肺继发气胸患者的临床特点.方法 分析54例尘肺继发气胸患者的70次住院病例特点.结果 54例患者中43例（79.6%）为尘肺叁期患者,17例（24.3%）无明显病情加重期,21例（30.0%）入院时未发现明显阳性体征.其中合并肺气肿39例（72.2%）,合并肺大泡20例（37.0%）,合并肺部感染28例（51.9%）.14.8%的患者有气胸复发史.结论 1.气胸的发生率随着尘肺期别的增加而增加;2.尘肺继发气胸易漏诊;3.尘肺继发气胸的患者并发症多,恢复时间长,复发率高.

Clinical observation on pneumoconiosis secondary pneumothorax

Objective To summarize the clinical characteristics of patients with pneumoconiosis secondary pneumothorax. Meth- ods The clinical characteristics of 54 patients with pneumoconiosis secondary pneumothorax, who were hospitalized for 70 times in total, were analyzed. Results 43 out of the 54 patients were pneumoconiosis at stage 111 （79.6%）. 17 of them had no obvious exacerbation （24. 3% ）. There were 21 cases without obvious positive signs at admission. 39 cases were complicated with pulmonary emphysema （72.2%）, 20 cases complicated with pulmonary bulla （37.0%）, and 28 cases complicated with pulmonary infection （51.9%）. 14. 8% of the patients had a history of recurrent pneumothorax. Conclusion 1. The incidence of pneumothorax becomes high with the increase of the stage of pneumoconiosis. 2. Patients with pneumoconiosis secondary pneumothorax are easily misdiagnosed. 3. Patients with pneumoconiosis secondar~ pneumothorax have many complications, and their recovery time is long with bizh recurrence.
