That's the bad news. The way to treat cyanide poisoning is to undo that binding process and free up the oxygen for cells to use. You need to remove the affected person from the source of the cyanide immediately. Induce vomiting if possible, or wash the stomach with a saline solution. Then give, of all things, poppers .
Amyl nitrite is a specific antidote.
You could give an intravenous infusion of sodium nitrite, followed by an infusion of sodium thiosulfate. You also might give 100 percent oxygen to support respiration. If symptoms recur, you repeat the process. Inc. All rights reserved. Reproduction in whole or in part without permission is prohibited.
