健康干预对电焊工肺通气功能的影响

Health Intervention on Pulmonary Function of Welders

目的分析健康干预对电焊工肺通气功能指标的影响,为制定的电焊工健康干预措施提供参考。方法以某石化公司检安二队38名电焊工为观察组,该公司检安一队36名电焊工为对照组,另选取两队不接触电焊和粉尘作业的32名工人为空白对照组。先做三组肺通气功能基线测试,再对观察组进行12周健康干预,测定其肺通气功能,并将测试结果与两组对照进行比较。结果经过12周的健康干预,观察组电焊工肺通气功能各项指标较之对照组有明显改善,其中FEV1出现统计学意义的差异(P<0.05);与空白对照组比较,虽然观察组肺通气功能各项指标仍然较低,但FEV1水平已经接近且差异没有统计学意义(P>0.05)。结论以阻断电焊烟尘接触为主要目的健康干预对预防电焊工肺通气功能的损害有着积极的意义。

Objective The analysis of health interventions on the influences on the indices of the pulmonary function of welders aims to provide reference to the development of health interventions for welders.Methods 38 welders of a repire-installation team of a petrochemical company were chosen as the observational team,36 welders of another repire-installation team of the company were chosen as the control group and 32 workers with no contact with welding dust from two teams were chosen as non-welders group.Firstly,test the baseline of the pulmonary function of the three groups and then after 12 weeks of health intervention applied to the observational group,the lung function of workers from this group will be measured.The results would be analyzed by comparing with that of both the control and non-control groups.Results After 12 weeks of health interventions,the indexes of the lung functions of the welders in the observational group,o f which there were differences of statistical significance in FEVI（P0.05）;compared with the non-welders group,although the observation of lung ventilation function of the indicators were still low,but FEV1 level was already close and the difference was not statistically significant（P0.05）.Conclusions Health intervention which aims to block the access to the welding fumes has positive meanings to the prevention of the damage to the lung functions of welders.
