Ethylene glycol is an odorless, sweet-tasting liquid found in industrial solutions such as antifreeze and windshield wiper fluid. Brake fluid, an automobile transmission liquid, contains poisonous alcohols such as glycol ethers and ethylene glycols. The toxicity of ethylene glycol is associated with toxic metabolite production by the liver enzyme alcohol dehydrogenase. Administration of either intravenous ethanol or fomepizole, both of which competitively inhibit ethylene glycol metabolism by alcohol dehydrogenase and can prevent the production and accumulation of the toxic metabolites, can be used as an antidote. A 42-year-old male car mechanic was transferred to our hospital after accidentally ingesting approximately 100 mL of brake fluid. Immediately after ingestion, he threw up most of the ingested liquid; however, he complained of nausea and throat pain and was moved to our emergency department. The patient was successfully treated with administration of oral ethanol in the form of whisky through a nasogastric tube since neither intravenous ethanol nor fomepizole was available in our hospital at the time of his presentation. Our case demonstrates that oral ethanol can be used as an alternative treatment for patients with ethylene glycol intoxication.
乙二醇是一种无味、味甜的液体,存在于防冻液和挡风玻璃清洗液等工业溶液中。制动液,一种汽车传动液,含有有毒醇类,如乙二醇醚和乙二醇。乙二醇的毒性与肝脏酶酒精脱氢酶产生的有毒代谢产物有关。静脉注射乙醇或甲吡唑都可以作为解毒剂,二者均可通过竞争性抑制酒精脱氢酶对乙二醇的代谢,从而防止有毒代谢产物的产生和积累。一名42岁的男性汽车修理工在意外摄入约100毫升制动液后被送往我院。摄入后,他立即吐出了大部分摄入的液体;然而,他抱怨恶心和喉咙疼痛,并被转移到我们的急诊科。由于患者就诊时我院没有静脉注射乙醇和甲吡唑,因此通过鼻胃管给他服用威士忌形式的口服乙醇,该患者得到了成功治疗。我们的病例表明,口服乙醇可作为乙二醇中毒患者的替代治疗方法。
