[A case of intravenous injection of mercury poisoning].

There are few reports of poisoning caused by high-dose intravenous injection of mercury. Its clinical manifestations are diverse and the risk of mortality is high. Currently, the pathogenesis is not clear and the treatment experience is insufficient, leading to difficulties in clinical diagnosis and treatment. In this article, the data of a case of mercury poisoning caused by intravenous self-administration was analyzed and summarized. The patient developed multiple organ dysfunction syndrome after intravenous injection of high-dose mercury. After comprehensive treatment, such as mercury removal, organ support, and infection prevention, the condition was improved. This case suggests that intravenous injection of mercury can cause damage to the functions of multiple organs, such as the heart, lungs, and kidneys. Early treatment and intervention can bring benefits. 一次性静脉注射大剂量汞引起中毒的报道很少，患者临床表现多样且汞致死风险高，目前存在发病机制不明确、治疗经验不足等问题，为临床诊疗及救治工作带来困难。本文对1例静脉注射大剂量汞引起中毒的病例资料进行整理。患者静脉注射大剂量汞后出现多器官功能障碍综合征，经过驱汞治疗、器官支持治疗、防治感染等综合救治后病情好转。提示静脉注射汞会对心脏、肺、肾等多器官功能造成损伤，早期系统干预治疗可以带来获益。.
