Abstract:
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.
