paralytic shellfish poisoning

Abbreviation: PSP
Poisoning after ingestion of shellfish contaminated by toxic marine algae that produce saxitoxin. Saxitoxin alters cell membrane permeability to sodium ions. It causes numbness and tingling, nausea and vomiting, and, in severe intoxications, paralysis and respiratory failure. Care includes the administration of intravenous fluids, respiratory support, and the oral administration of activated charcoal.
