Cyanide antidote kit is a widely used method in treating cyanide induced histotoxic hypoxia. It consists of three different parts that are administered one after the other. The three parts are amyl nitrite, sodium nitrite, and sodium thiosulfate. [3] The nitrites act with hemoglobin to form methemoglobin which binds cyanide.
The symptoms of poisoning vary depending on substance, the quantity a dog has consumed, the breed and size of the mammal.A common list of symptoms are digestion problems, such as vomiting, diarrhea, or blood in stool; bruising and bleeding gums, nose, or inside the ear canal; behavioral changes, such as lethargy, hyperactivity, and seizures; unusual items found in the dog's stool.
Cyanide poisoning inhibits aerobic respiration and therefore increases anaerobic glycolysis which causes a rise of lactate in the plasma. A lactate concentration above 10 mmol per liter is an indicator of cyanide poisoning, as defined by the presence of a blood cyanide concentration above 40 μmol per liter.
Cyanide is unstable in water, but the reaction is slow until about 170 °C. It undergoes hydrolysis to give ammonia and formate, which are far less toxic than cyanide: [14] CN − + 2 H 2 O → HCO − 2 + NH 3. Cyanide hydrolase is an enzyme that catalyzes this reaction.
Amygdalin (Laetrile) is a toxic drug that is not effective as a cancer treatment". Additionally, "No controlled clinical trials (trials that compare groups of patients who receive the new treatment to groups who do not) of laetrile have been reported." [24] The side effects of laetrile treatment are the symptoms of cyanide poisoning.
Sodium nitrite/sodium thiosulfate, sold under the brand name Nithiodote, is a fixed-dose combination medication used as an antidote for cyanide poisoning. [1] It contains sodium thiosulfate and sodium nitrite. [1] It is given by intravenous infusion into a vein. [1] It was approved for medical use in the United States in January 2011. [2]
Poisoning is the harmful effect which occurs when toxic substances are introduced into the body. [1] The term "poisoning" is a derivative of poison, a term describing any chemical substance that may harm or kill a living organism upon ingestion. [2] Poisoning can be brought on by swallowing, inhaling, injecting or absorbing toxins through the skin.
Sodium thiosulfate is a classical antidote to cyanide poisoning, [10] For this purpose it is used after the medication sodium nitrite and typically only recommended for severe cases. [4] [6] It is given by injection into a vein. [4] In this use, sodium nitrite creates methemoglobinemia which removes cyanide from mitochondria. [6]
