目的通过分析乐山市煤炭行业尘肺病例晋期特点,掌握尘肺病程进展情况,为尘肺病诊断和防治工作提供参考数据。方法收集整理乐山市煤炭行业2001—2013年发生的275例尘肺晋期病例资料,以13年为观察期分析尘肺病晋期特征。结果晋期患者平均接尘时间为(22.2±8.3)a,13年间总晋期率为9.9%,壹期晋贰期占78.6%,平均时间(5.7±4.5)a,贰期晋叁期(6.5±4.1)a,壹期跳到叁期(11.1±7.9)a,总平均晋期时间(6.0±4.7)a。10年内晋期比例为65.1%,晋期患者工种以采煤、掘进和采掘混合为主,有并发症的病例占晋期总数的8.0%。结论 13年来乐山市煤炭行业尘肺病例以壹期晋贰期为主,10年以内晋期发生比例偏高,接尘时间长,晋期时间短,工种以尘肺高发的采煤和掘进为主,需要加强职业健康监护,保护劳动者健康。
Objective To analyze the characteristics of pneumoconiosis cases in the coal industry in Leshan City and grasp the progress of pneumoconiosis course so as to provide reference data for the diagnosis and control of pneumoconiosis. Methods A total of 275 cases of pneumoconiosis were collected from 2001 to 2013 in the coal industry of Leshan City. The characteristics of the advanced stages of pneumoconiosis were analyzed with 13 years as the observation period. Results The average dusting time of patients in Jin stage was (22.2 ± 8.3) years, the total Jin period rate was 9.9% in 13 years, 78.6% in Jin II stage, the average time was 5.7 ± 4.5 days, 6.5 ± 4.1) a, the period of one jump to three periods (11.1 ± 7.9) a, the total average time of promotion (6.0 ± 4.7) a. The ratio of Jin in 10 years was 65.1%. In the Jin period, the number of patients was dominated by coal mining, excavation and mining, and the number of complications accounted for 8.0% of the total. Conclusions The dust pneumoconiosis cases in the coal industry of Leshan City during the past 13 years were dominated by the second phase of the second phase of Jinping. In the first 10 years, the proportion of pneumoconiosis was relatively high, the duration of dust collection was long and the period of the Jin period was short. The main types of work were pneumoconiosis and coal mining. Need to strengthen occupational health monitoring, to protect the health of workers.
