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.
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.
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]
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.
Sodium nitrite is used as a medication together with sodium thiosulfate to treat cyanide poisoning. [26] It is recommended only in severe cases of cyanide poisoning and has largely been replaced by use of hydroxocobalamin, [27] a form of vitamin B12, but given in much higher doses than needed nutritionally.

Karen Gaylord posted that her 7-month-old dog ingested discarded weed at the dog park, where she has seen "pot scraps" in the parking lot on several occasions. Gaylord encouraged efforts to spread ...
The sine qua non of strychnine toxicity is the "awake" seizure, in which tonic-clonic activity occurs but the patient is alert and oriented throughout and afterwards. [23] Accordingly, George Harley (1829–1896) showed in 1850 that curare (wourali) was effective for the treatment of tetanus and strychnine poisoning.
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.
