[Investigation and analysis of 7 cases of acute lung injury caused by a welding operation].

Objective: Throughing the investigation and analysis of seven cases of acute lung injury caused by a welding operation, the hazards and production pathways of harmful gases such as phosgene and nitrogen oxides are understood, which will serve as a reference for preventing similar events in the future. Methods: Throughing the accident scene environment investigation and clinical case analysis, combined with the laboratory test results, carried on the comprehensive analysis. Results: The accident caused a total of 7 people to suffer from acute lung injury to varying degrees. Three of them were sent to the ICU ward for treatment due to acute respiratory failure. After active treatment, 7 people were discharged from the hospital with obvious relief. Conclusion: Welding is also a kind of profession that causes the high incidence of acute lung injury accidents. It is necessary to strengthen the knowledge training and protection awareness education of welding workers to avoid the occurrence of acute harmful gas poisoning accidents.目的： 通过调查分析一起焊接作业致7例急性肺损伤事故，了解光气、氮氧化物等有害气体的危害及产生途径，为今后预防类似事件起到借鉴作用。 方法： 2017年5月，通过事故现场环境调查及7例患者临床分析，结合实验室检测结果，进行综合分析。 结果： 该事故共造成7人出现不同程度的急性肺损伤，其中3人因急性呼吸衰竭被送入ICU病房治疗，经过积极治疗，7人均以病情明显缓解先后出院。 结论： 焊接作业是导致急性肺损伤事故高发职业，应加强焊接作业工人的知识培训和防护意识教育，避免急性有害气体中毒事故的发生。.
