Diquat (DQ) is a non-selective, foliage-applied herbicide that is known to cause liver and kidney damage, while the impact on the lungs is relatively mild. Current domestic and international reports on diquat poisoning primarily focus on liver and kidney injuries, with limited documentation of cases leading to acute respiratory distress syndrome (ARDS) and lung damage. This paper presents a retrospective analysis of two documented cases of diquat poisoning, both exhibiting ARDS. In both cases, the condition rapidly progressed upon the onset of ARDS despite aggressive treatment, ultimately resulting in the death of the patients.
敌草快（diquat，DQ）是一种非选择性、落叶型除草剂，其中毒往往引起肝肾功能损伤，而对肺的损伤较为轻微。目前国内外对于DQ中毒的报道多集中在肝肾损伤，而引起急性呼吸窘迫综合征（ARDS）及肺部损伤的报道较少。本文回顾分析了2例成分明确标注为敌草快中毒的病例，均表现出ARDS，且在出现ARDS时病情急剧进展，虽经积极救治，最终患者均死亡。.
