Tetrodotoxin Poisoning - Fugu - Medical Minute

Tetrodotoxin is lethal poison that blocks sodium channels. A famous sushi called "Fugu" is cut from a puffer fish that contains this poison. The idea is to get just enough of the toxin to cause peri-oral paresthesia but not too much to get seizures, paralysis and cardiac dysrrhythmias. A recent outbreak in Minneapolis, Minnesota was just reported in the MMWR so it can really happen anywhere, its a great read - dried puffer was bought from a market in NYC. http://www.cdc.gov/mmwr/preview/mmwrh... 2-3 mg of the toxin is lethal to an adult human. No antidote exists though I would try hypertonic sodium bicarbonate for the cardiac dysrrhythmias and appropraite supportive. If the patient survives 24 hrs, the patient will do well without sequelae if appropriately supported.
