Ingestion of corrosive substances can severely burn the upper digestive tract leading to bleeding or perforation, and may even be life-threatening. Less commonly, damage to the trachea and bronchi is involved. In this paper, a case of corrosive digestive tract injury and lung injury after oral administration of pipeline dredging agent (the main components are hydroxide, sodium carbonate, sodium hypochlorite, etc.) was analyzed. After active rescue treatment, the patient died of massive hemoptysis. It is suggested that serious complications may occur after ingestion of corrosive substances. Timely diagnosis and reasonable medical management are needed to improve the level of recognition and treatment of such diseases.
摄入腐蚀性物质可能严重烧伤上消化道导致出血或穿孔，甚至可能危及生命，较少涉及气管支气管损伤。本文分析1例口服管道疏通剂（主要成分为氢氧化物、碳酸钠、次氯酸钠等）后腐蚀性消化道损伤及肺损伤的病例，经积极抢救治疗，最终因发生大咯血而死亡。提示摄入腐蚀性物质后可能出现严重的并发症，需要及时诊断及合理的医疗管理，以提高这类疾病的识别及救治水平。.
