35. Antidote in Cynanide Poisoning -
a.NaCl
b. NaHCO3
c. Sodium Thiosulphate
d. None
Ans – Sodium Thiosulphate.
Cyanide poisoning occurs when a living organism is exposed to a compound that produces cyanide ions (CN−) when dissolved in water.The cyanide ion halts cellular respiration by inhibiting an enzyme in mitochondria called cytochrome c oxidase.
Cyanide poisoning is a form of histotoxic hypoxia because the cells of an organism are unable to use oxygen, primarily through the inhibition of cytochrome c oxidase.Cyanide toxicity can occur following the ingestion of large doses of amygdalin (found in almonds and apricot kernels and marketed as an alternative cancer cure), prolonged administration of sodium nitroprusside, and after exposure to gases produced by the combustion of synthetic materials.
standard cyanide antidote kit first uses a small inhaled dose of amyl nitrite, followed by intravenous sodium nitrite, followed by intravenous sodium thiosulfate.]Hydroxocobalamin is newly approved in the US and is available in Cyanokit antidote kits
