摘要哒螨灵（Pyridaben）是一种被广泛运用在农作物上的广谱杀螨剂，误服或者自服大剂量哒螨灵会引起患者多器官功能障碍综合征，因其对多脏器产生损伤且无特效解毒剂，死亡率较高。本文报道2例服用大量哒螨灵农药患者，出现严重代谢性酸中毒、高乳酸血症、中毒性脑病以及肝脏、肾脏、心脏及消化道损伤情况，经及时的洗胃、导泻、脏器支持及血液净化治疗后病情好转出院。以期对哒螨灵农药中毒的治疗提供临床思路。

Due to its damage to multiple organs and no specific antidote, the mortality rate is high. This paper reports two patients who took a large amount of pyridaben, developed severe metabolic acidosis, hyperlactatemia, toxic encephalopathy, and liver, kidney, heart and digestive tract damage. After timely gastric lavage, catharsis, organ support andblood purification treatment, the condition improved and discharged. It is expected to provide clinical ideas for the treatment of pyridaben poisoning.
