How does nitroprusside cause cyanide toxicity?

Mechanism of toxicity. Nitroprusside is rapidly hydrolyzed (half-life, 11 minutes) and releases free cyanide, which normally is converted quickly to thiocyanate by rhodanase enzymes in the liver and blood vessels.

Lorazepam is the drug of choice; midazolam and phenobarbital are second-line agents. Cyanide antidotes are the key medications for hydrogen cyanide (HCN) poisoning. Hydroxocobalamin (HCO, vitamin B-12) is the first-line therapy for cyanide toxicity.

How do you treat cyanide poisoning Usmle?

Treatment

1. Management approach. supplemental oxygen is not useful in this case. all contaminated clothes should be removed.
2. First-line. hydroxocobalamin, a precursor to vitamin B12. combines with cyanide to form cyanocobalamin, which is renally excreted.
3. Second-line. nitrates.
4. Other treatments. activated charcoal.

What causes nitroprusside cyanide to be toxic?

Nitroprusside Cyanide Toxicity is due to the cyanide groups released from metabolism of the nitroprusside molecule.

What are the side effects of cyanide toxicity?

Symptoms: Cyanide toxicity is often associated with the odor of almonds on breath and can result in acidosis, tachycardia, mental status changes, and death. How to intervene: Patients with cyanide toxicity should be mechanically ventilated with 100% oxygen to maximize oxygen availability.

Who was the first person to die from cyanide?

Swedish chemist Carl Wilhelm Scheele first isolated cyanide in 1782. He reportedly died due to cyanide poisoning in 1786. Since that time cyanide has earned its reputation as a powerful and deadly poison. Fear of cyanide is augmented by its quick and lethal action, and numerous sources.
