Ethylene Glycol – What Every Pet Owner Should Know. How is ethanol used in the treatment of ethylene glycol toxicity? Conclusion When an unsuspecting pet first licks up the antifreeze — which, sadly, many do — the ethylene glycol (EG) can cause early signs such as: Antifreeze Toxicity in Dogs. Although less toxic than EG, ingestion of propylene glycol (PG) may be associated with a toxic syndrome similar to the acute phase of EG toxicosis. Pathogenesis Etiology. ANSWERS. Another issue that polyethylene glycol has is contamination. Hewlett TP(1), Jacobsen D, Collins TD, McMartin KE. Although less toxic than EG, ingestion of propylene glycol (PG) may be associated with a toxic syndrome similar to the acute phase of EG toxicosis. How is 4-methylpyrazole used in the treatment of ethylene glycol toxicity? Ingestion of ethylene glycol (EG) is a frequently encountered toxicity in dogs and cats. Ethylene glycol (anti-freeze) toxicity is a serious emergency in both veterinary and human medicine. Ethylene glycol is metabolized similarly to ETHANOL thus it is not surprising that animals show ataxia & CNs depression approx. Long term outcomes may include kidney failure and brain damage. Treatment for ethylene glycol poisoning includes the antidote fomepizole (also known as 4-MP) or ethanol. The oral LD 50 of PG in dogs is ~9 mL/kg. If the dog exhibits any of these symptoms have the vet check the animal. Ethylene glycol can also be found, in lower concentrations, in some windshield de-icing agents, hydraulic brake fluid, motor oils, solvents, paints, film processing solutions, wood stains, inks, printer cartridges, etc. Toxicity and death may occur after drinking even a small amount. Fomepizole has been effectively used in dogs with ethylene glycol toxicity (Connally and others 1996) but it is currently unavailable as a licensed veterinary product in … Malicious poisoning. Ethylene Glycol Poisoning in Dogs. Antifreeze products will mostly contain Ethylene glycol, Propylene glycol or Methanol as the active ingredient. above is a valuable contribution, owing particularly to an absence of any previous equine evidence of ethylene glycol toxicity reported in the scientific literature. therapy. (undiluted = 95% ethylene glycol, working solution in car radiator is 50%). Toxicity to pets. Recent references from PubMed and VetMedResource. It is a colorless, odorless, and sweet-tasting solution. Follow the diagnostic tree for Evaluating Ataxia in Suspected Ethylene Glycol Toxicity Evaluating Ataxia in Suspected Ethylene Glycol Toxicity. EG is found in antifreeze (95% solution), windshield de-icing agents, and some industrial solvents (detergents, photographic developing solutions, brake fluid, motor oil, paints, wood stains, and polishes). Further Reading Publications Refereed papers. Without a doubt untreated ethylene glycol intoxication will kill a dog. Ethylene Glycol Poisoning in Dogs. Depending on the way polyethylene glycol is manufactured, PEG can contain contaminants like ethylene oxide and 1,4-dioxane. Ethylene glycols peak at 1-4 hours post-ingestion and then begin to fall. Ethylene glycol (EG) toxicity Extended Version Prognosis: Good: Dogs treated within 5 hours, cats within 3 hours Guarded to poor: Very large doses presenting with seizures, nystagmus Prevention: Do not keep animals in the garage Lock antifreeze containers away from chewing dogs Ethylene glycol poisoning is common because antifreeze is widely used, it has a sweet taste and small lethal dose (only 3 to 4 teaspoons in dogs, 1 to 2 teaspoons in cats), and it … Ethylene glycol exposure can be extremely dangerous, with significant morbidity and mor … These 95% commercial antifreeze preparations are diluted ~50% with water when used in vehicle cooling systems. Electrocution In cats, ingestion of a diet containing 6%–12% PG can result in Heinz body formation and decreased RBC survival. Many animals will voluntarily drink ethylene glycol if antifreeze is spilled or leaks onto garage floors or driveways. Ethylene glycol is subsequently converted into more toxic metabolites, Ethylene glycol toxicity in a dog. Most antifreezes contain ethylene glycol, a chemical compound that causes significant, often fatal, problems for both cats and dogs. Like ethylene glycol, propylene glycol may be used as an antifreeze and can be found in high concentrations in RV, marine, and “pet safe” antifreeze products. ), a negative test does not rule out ethylene glycol toxicity. Why can't it be used in cats? Ethylene glycol has a very narrow margin of safety – which means only a tiny amount can result in severe poisoning. Both dogs and cats may be attracted to ethylene glycol by its sweet taste. 5. 30 min after ingestion. The sweet taste and smell can be very enticing for pets, so always keep it securely stored! Most intoxications are associated with ingestion of antifreeze, which is typically 95% EG. When dogs and cats are exposed to antifreeze, it is essential that they immediately receive treatment. Ethylene glycol poisoning is a potentially fatal condition that results from the ingestion of substances containing ethylene glycol, an organic compound commonly seen in antifreeze. Ethylene glycol tests often are not beneficial after 12 hours post-ingestion. Ethylene glycol toxicity: a retrospective pathological study in cats SHORT COMMUNICATION Before being metabolized, much like the excessive consumption of alcohol in human patients, EG causes irritation of the gastric mucosa, along with central nervous system depression. Antifreeze poisoning is a medical emergency, and early treatment is crucial. Ethylene glycol (C2H6O2) is a toxic alcohol that is found in various household and industrial agents. Ethylene glycol is the ingredient found in most antifreeze products, usually at a concentration of 95-97%. 3. Author information: (1)Department of Pharmacology and Therapeutics, Louisiana State University Medical Center, Shreveport 71130-3932. Ethylene glycol, a sweet-tasting, odorless liquid, is the active ingredient in antifreeze. Ethylene glycol (E/G) is the active anti-freeze principle in radiator water additives. The treatment of choice for dogs is a drug called Fomepizole (or 4 - methylpyrazole or 4- MP). Fomepizole is expensive but life-saving when administered to dogs within the first 8-12 hours of ingestion. Antifreeze poisoning occurs when pets drink antifreeze containing ethylene glycol. All animals are susceptible to ethylene glycol (EG) toxicity, but it is most common in dogs and cats. In cats, ingestion of a diet containing 6%–12% PG can result in Heinz body formation and decreased RBC survival. This drug is administered intravenously multiple times over 24- 36 hours to prevent the development of kidney failure. However, there are a number of tests that together may indicate antifreeze poisoning if performed in a timely manner. The oral LD 50 of PG in dogs is ~9 mL/kg. Ethylene glycol (EG) toxicity results from its metabolism to glycolic acid and other toxic metabolites. Antifreeze, which often contains ethylene glycol (EG), can be extremely dangerous to dogs and cats. Your vet will confirm ethylene glycol toxicity by taking a sample of your dog’s urine and looking for the presence of crystals under a microscope. Stage 1: This occurs within 30 minutes to 12 hours and looks similar to alcohol poisoning. Best Answer. The purpose of the current study was to determine if the Catachem test kit (Catachem Inc., Oxford, Connecticut) could precisely and accurately detect the presence of EG added to serum and plasma from 6 dogs and 4 cats. It is an extremely dangerous toxin and the lethal dose for dogs is 2-3 ml/lb, and for cats it is 0.64 ml/lb. The liver quickly breaks down ethylene glycol into toxic products that can lead to kidney failure and death. ... Once the dog has ingested this ethylene glycol it becomes toxic in their bodies. The minimum lethal dose of ethylene glycol is 4-6 ml/kg body weight in dogs.” According to Pet Poison Helpline, common signs of ethylene glycol poisoning occur in stages. Even a small amount of antifreeze can be fatal to dogs and cats. Antifreeze consumed as concentrated solution. Since it has a wider margin of safety as compared to its chemical cousin, ethylene glycol, it is commonly used to absorb extra water and maintain moisture in certain medicines, cosmetics, or dog and human food products. 2 Ethylene glycol is most commonly found in automotive antifreeze and is also used as a precursor to industrial polymers. In contrast to the other two types of antifreeze, it only takes a small amount of ethylene glycol to poison your dog, and even less to poison your cat – just two tablespoons for a ten-pound dog and one teaspoon for a cat. (2) So, while a positive ethylene glycol test has a good chance of suggesting toxicity (although false positives can occur! ; Richards L, Ong H M, Davis M, Hodge P (2011) Ethylene glycol toxicity in a cat.Control & Therapy Series 263, 44-46.; Tart K M, Powell L L (2011) 4-methylpyrazole as a treatment in naturally occurring ethylene glycol intoxication in cats.J Vet Emerg Crit Care 21 (3), 268-272 PubMed.
