Cyanide is a potent and rapidly-acting asphyxiant which prevents tissue utilization of oxygen by inhibition of the cellular respiratory enzyme, cytochrome oxidase. Inhalation or ingestion of cyanide produces reactions within a few seconds and death within minutes. ⋯ Biological detoxification of cyanide is available through several routes, and the application of sodium nitrite with sodium thiosulfate or administration of methylene blue are effective treatment procedure. The environmental availability of cyanide in its various forms necessitates an understanding of its pathophysiology and responsible management of hazardous situations.
