[A suspected case of delayed encephalopathy after acute hydrogen sulfide poisoning]

The main component of the gas in the fish storage tank is hydrogen sulfide. Hydrogen sulfide poisoning is a common occupational chemical poisoning among fishermen in summer, and acute hydrogen sulfide poisoning can manifest as toxic encephalopathy. This paper analyzes a patient with delayed encephalopathy suspected of acute hydrogen sulfide poisoning. The patient was unconscious for 18 days after waking up for 5 days after acute hydrogen sulfide poisoning. After waking up again, there were symptoms such as decreased limb muscle strength, ataxia, swallowing, dysarthria, and the clinical characteristics were significantly different from those of delayed encephalopathy caused by acute carbon monoxide poisoning, such as decreased cognitive function and damage to extrapyramidal system.储鱼舱气体的主要成分是硫化氢，硫化氢中毒是夏季渔民常见的职业性化学中毒，而急性硫化氢中毒可表现为中毒性脑病。本文对1例疑似急性硫化氢中毒所致迟发性脑病患者进行分析，患者在发生急性硫化氢中毒清醒5 d后，昏迷18 d；再次清醒后，出现四肢肌力下降、共济失调并吞咽、构音困难等症状，其临床特点与急性一氧化碳中毒迟发性脑病表现为认知功能下降及锥体外系受损有明显不同。.
