Intravenous sodium thiosulfate is administered for about 30 minutes. Hydroxocobalamin will detoxify cyanide by binding with it to produce nontoxic vitamin B This medication neutralizes cyanide at a slow enough rate to allow an enzyme called rhodanese to further detoxify cyanide in the liver. If you suspect you or a loved one is experiencing symptoms of severe cyanide poisoning, seek immediate emergency medical attention. Your outlook will depend on the type of cyanide present, the dose, and how long you were exposed.
Early diagnosis and treatment are key to reducing your risk of complications. Moderate levels of acute or chronic exposure may also be resolved with quick diagnosis and treatment.
In severe cases, symptoms are often sudden and life-threatening. Immediate emergency medical attention is necessary.

Discriminating between the two can be difficult.
A stomach bug and food poisoning can be commonly…. Roundup is a popular weed killer with glyphosate as the main ingredient. The use of Roundup is highly controversial, and some claim that it can cause…. Pesticides are used in farming to kill weeds and insects. You can put your eyeglasses back on after you wash them. If you are wearing jewelry that you can wash with soap and water, you can wash it and put it back on. If it cannot be washed, it should be put with the contaminated clothing.
Disposing of your clothes: After you have washed yourself, place your clothing inside a plastic bag. Avoid touching contaminated areas of the clothing. An alternative method is to put the clothes in the bag using tongs, tool handles, sticks, or similar objects. Anything that touches the contaminated clothing should also be placed in the bag. If you wear contacts, put them in the plastic bag, too.
Seal the bag, and then seal that bag inside another plastic bag. Disposing of your clothing in this way will help protect you and other people from any chemicals that might be on your clothes. When the local or state health department or emergency personnel arrive, tell them what you did with your clothes. The health department or emergency personnel will arrange for further disposal. Do not handle the plastic bags yourself. For more information about cleaning your body and disposing of your clothes after a chemical release, see Chemical Agents: Facts About Personal Cleaning and Disposal of Contaminated Clothing.

In , the Japanese cult Aum Shinrikyo placed cyanide in subway bathrooms. Mechanism of Action and Toxicokinetics Cyanide poisons the mitochondrial electron transport chain within cells and renders the body unable to derive energy adenosine triphosphate-ATP from oxygen. Signs and Symptoms Cyanide kills quickly: death occurs within seconds of a lethal dose of cyanide gas and within minutes of ingestion of a lethal dose of cyanide salt.
Signs and symptoms of cyanide poisoning include the following: CNS : headache, anxiety, agitation, confusion, lethargy, seizures, and coma; Cardiovascular : decreased inotropy, bradycardia followed by reflex tachycardia, hypotension, and pulmonary edema; and Other : acute lung injury, nausea and vomiting, cherry-red skin color.
Countermeasures Before cyanide antidote can be administered, the patient must be removed from the cyanide-laden area, clothing removed, and skin washed with soap and water. Cyanide Antidote Kit : This 3-component process comprising amyl nitrite, sodium nitrate, and sodium thiosulfate releases cyanide from cytochrome a3 by providing a target for which cyanide has a higher attraction. Amyl nitrite, contained in pearls that must be broken and inhaled, and IV sodium nitrate cause the formation of methemoglobin, for which cyanide has a high binding affinity.
Sodium thiosulfate provides a source of sulfur that the enzyme rhodanese-the major pathway for metabolism of cyanide-utilizes to detoxify cyanide. Hydroxocobalamin Cyanokit : In addition to methemoglobin, cyanide also has a strong binding affinity to cobalt. Hydroxocobalamin, which contains cobalt, becomes cyanocobalamin vitamin B12 after binding to cyanide.
In the body, cyanide in small amounts can also combine with another chemical to form vitamin B 12 , which helps maintain healthy nerve and red blood cells. Large doses of cyanide prevent cells from using oxygen and eventually these cells die. The heart, respiratory system and central nervous system are most susceptible to cyanide poisoning. The health effects from high levels of cyanide exposure can begin in seconds to minutes.
Some signs and symptoms of such exposures are:. The severity of health effects depends upon the route and duration of exposure, the dose, and the form of cyanide. Moving away from the point of exposure to fresh air is an important first step in treating cyanide exposure. Cyanide poisoning can be further treated by medical professionals. Often patients are given oxygen. Two antidotes sodium nitrite and sodium thiosulfate are usually used to stop the effects of serious cyanide poisoning.
Other drugs may be necessary to control additional health effects of cyanide such as seizures. People who experience serious signs and symptoms will need immediate hospital care, especially individuals who have "passed out" or are unconscious.
Any delay could result in death. While an elevated blood cyanide concentration may indicate that someone has been exposed to cyanide, laboratory testing for cyanide exposure will not be useful in making emergency treatment decisions.
A patient exposed to cyanide should not expect medical personnel to do these tests before treatment. Treatment should not be delayed if signs and symptoms are present and exposure is believed to have occurred.
