目的探讨肺功能与动脉血气对尘肺病患者劳动能力鉴定的影响,以及两者检查的差异性,为劳动能力鉴定的应用提供科学依据。方法对湖南省职业病防治院受理劳动能力鉴定的182例尘肺病患者同时进行肺功能与动脉血气测定,对其结果进行对比分析。结果182名尘肺病患者中肺功能异常率占76.9%(140/182),低氧血症占23.1%(42/182),两者的差异有统计学意义(P<0.01),低氧血症随着期别的增高而加重(P<0.01),5项肺功能检测指标中,以残气/肺总量(RV/TLC)、一氧化碳弥散量(DLco)和第1秒用力呼气量(FEV1)异常为主,异常率分别为55.5%、42.9%、35.7%。依据肺功能结果判定劳动能力平均等级为(4.9±1.5)级,依据动脉血气结果判定劳动能力平均等级为(6.2±1.5)级,2种不同指标判定劳动能力等级有明显的差异(P<0.01)。结论肺功能检测和血气分析在劳动鉴定中差异较大,在加强检查质量控制的同时,应综合评定肺功能损伤程度,以提高鉴定结果的准确性和可靠性。
Objective To investigate the effects of pulmonary function and arterial blood gas on the identification of labor ability of patients with pneumoconiosis and the differences between the two tests in order to provide a scientific basis for the appraisal of labor ability. Methods A total of 182 patients with pneumoconiosis admitted to Hunan Provincial Occupational Disease Prevention and Treatment Hospital were tested for pulmonary function and arterial blood gas at the same time. The results were compared and analyzed. Results Among 182 pneumoconiosis patients, the rate of lung dysfunction was 76.9% (140/182) and hypoxemia was 23.1% (42/182), the difference was statistically significant (P <0.01) (P <0.01). Among the five indexes of pulmonary function test, RV / TLC, DLco, and forced expiratory volume in 1 second (FEV1), the abnormal rates were 55.5%, 42.9% and 35.7% respectively. The average level of labor ability was (4.9 ± 1.5) based on the results of pulmonary function test. The average level of labor ability was 6.2 ± 1.5 according to the results of arterial blood gas test. There were significant differences in the ability level of two kinds of labor tests (P <0.01) ). Conclusion Pulmonary function tests and blood gas analysis are quite different in labor appraisal. In order to strengthen the quality control of the examination, the degree of lung function impairment should be evaluated comprehensively to improve the accuracy and reliability of the appraisal results.
