propylene glycol poisoning in dogs

The ingredient found in antifreeze that is poisonous to dogs and cats, is ethylene glycol, which make up 95 percent of the antifreeze. According to vetinfo.com, antifreeze poisoning in dogs and cats is the most common form of poisoning in the United States. Ethylene glycol poisoning is poisoning caused by drinking ethylene glycol. 13 Propylene glycol (PG) is one of the least toxic glycols.. Cats are particularly sensitive to PG and its use is no longer allowed in cat foods. Propylene glycol antifreeze products are more environmentally friendly, and in addition to being less likely to cause fatal poisoning, they don’t taste like candy the way ethylene glycol products do, so … 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 is often stored and disposed of improperly. All animals are susceptible to ethylene glycol (EG) toxicity, but it is most common in dogs and cats. 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. Propylene glycol (IUPAC name: propane-1,2-diol) is a viscous, colorless liquid, which is nearly odorless but possesses a faintly sweet taste.Its chemical formula is CH 3 CH(OH)CH 2 OH. N2 - Objective: To describe the clinical course, treatment, and outcome of a dog with propylene glycol intoxication. Zinc, copper, and naphthalene poisoning are other types that will need to be ruled out. Ingestion of ethylene glycol (EG) is a frequently encountered toxicity in dogs and cats. Ethanol is the treatment of choice for cats and is administered for up to 64 hours. “Propylene glycol ingested at toxic doses can cause central nervous system depression and lactic acidosis, Brutlag says. Sadly, most manufacturers don’t know about all the research being done into polyethylene glycol and its derivatives. Prevention is key. Ethylene Glycol Poisoning in Dogs (In addition to being found in the car's engines to prevent freezing and overheating, it is used in hydraulic brake fluids.) It is believed that background concentrations of ethylene glycol in air, soil, surface and groundwater do not lead to poisoning. T1 - Propylene glycol intoxication in a dog. It is best to keep the story about antifreeze poisoning simple—put simply, it kills. Tufts Veterinary Newsletter reported that a medium-sized dog would have to ingest about 20 ounces of propylene glycol before getting seriously ill. Although it is considered safe, large intravenous doses given over a short period of time can be toxic. Propylene glycol toxicity is metabolized to compounds that are normal constituents of the citric acid cycle. New or Unique Information Provided. Propylene glycol, although not entirely nontoxic, is considerably less toxic than ethylene glycol and has been reported to affect the central nervous system but not the kidneys. With that said, while dog food may contain 5-10 percent of Propylene Glycol and not be toxic for them, that’s in a diluted form mixed with other food matter. Antifreeze products will mostly contain Ethylene glycol, Propylene glycol or … Request PDF | Propylene glycol intoxication in a dog | To describe the clinical course, treatment, and outcome of a dog with propylene glycol intoxication. Antifreeze. Antifreeze poisoning in dogs is a very serious matter. Should a dog lick up some concentrated Propylene Glycol – even 1 to 1.5 teaspoons full – that can be enough to begin to cause issues. However, propylene glycol is considerably safer (less toxic) than its far more dangerous cousin — ethylene glycol. Earlier this year, the manufacturer of the preferred antidote (remedy for the poison) for treating ethylene glycol poisoning in cats and dogs asked the FDA to pull their approval for the drug — called fomepizole (a.k.a. Antifreeze poisoning in dogs. 2 Ethylene glycol is most commonly found in automotive antifreeze and is also used as a precursor to industrial polymers. The dog made a full recovery. Over 10,000 dogs and cats are poisoned with automotive antifreeze each year. Propylene glycol is a controversial additive used to help preserve the moisture content in some commercial dog foods.. You may already recognize this chemical for its more everyday use — as the key component in newer automotive antifreeze.. The oral median lethal dose (LD50) of propylene glycol in dogs has been reported to be ~9 ml/kg body weight. Three stages of poisoning can be seen with ethylene glycol: 12 Almost all (98%) affected children died in a 1996 epidemic in Haiti. It has occasionally been substituted for propylene glycol in pharmaceutical preparations, resulting in the deaths of more than 100 persons in some incidents. Dogs usually come into contact with antifreeze when it leaks from a car's engine onto the ground, when it is spilled onto the ground while being added to a car's engine, or when the container is left uncapped. There are a few differential diagnoses of chive poisoning in dogs. While propylene glycol antifreeze is more expensive, it’s safe for pets and other wildlife, so please consider using this instead. Some “pet-safe” antifreeze products contain propylene glycol, which is much safer than ethylene glycol if ingested. Propylene glycol poisoning is marked initially by CNS depression and an elevated osmolal gap and, later, by an increased anion gap. Propylene glycol products are biodegradable, anti-corrosive, and recyclable. DEG is less toxic than ethylene glycol in most species, but more toxic than propylene glycol. Long term outcomes may include kidney failure and brain damage. Experts note that factors that affect the risk of poisoning when exposed to ethylene glycol include its dose, duration and nature of contact. To the authors' knowledge, this is the first report of documented propylene glycol intoxication in a dog, as well as the first report to describe hemodialysis as treatment for propylene glycol intoxication in a dog. It is a colorless, odorless, and sweet-tasting solution. Propylene glycol is a commonly used solvent for oral, intravenous, and topical pharmaceutical preparations. Later symptoms may include a decreased level of consciousness, headache, and seizures. AU - Poppenga, Robert H. PY - 2011/12. Automotive antifreeze kills 10, 000 of these pets every year. Underlying renal insufficiency and hepatic dysfunction raise risk for toxicity. Antifreeze, specifically ethylene glycol, is a highly toxic substance that smells and tastes sweet to pets and can cause serious, sometimes fatal health problems in both cats and dogs. A dog only needs to ingest 2 to 3 milliliters of ethylene glycol per pound of body weight to get a lethal dose of the toxin; cats only need to ingest 0.64 milliliters for the same effect. Many dog owners know that antifreeze is poisonous to dogs, but not all people understand how dangerous antifreeze poisoning can really be.Unfortunately, exposure to even a small amount of toxic antifreeze can quickly lead to death. AU - Claus, Melissa A. 2 – 11 The most recent mass DEG poisoning occurred in India in 1998. Fomepizole (Antizol-Vet®, 4-methylpyrazole) is the treatment of choice for ethylene glycol poisoning in dogs. If cats or dogs ingest large amounts of propylene glycol, poisoning can occur.. Marketed as smoke-free substitutes for traditional cigarettes, they’re shaped like a long cigarette, battery operated, and filled with a replaceable cartridge of E-liquid that contains a mixture of ingredients such as nicotine, flavorings, glycerin and propylene glycol. 4-MP) — because they have discontinued production of the drug. Therefore, now the ethylene glycol has been replaced with propylene glycol. Antifreeze poisoning in dogs typically occur when ethylene glycol, one of the main ingredients in antifreeze, ... but there is some hope as there is a safer alternative. Antifreeze is an engine coolant. If the above wasn’t enough, polyethylene glycol also destroys the beneficial bacteria found on your dog’s skin and inside their stomachs. Propylene glycol poisoning, acetaminophen, vitamin K, or benzocaine toxicity symptoms are similar to chives poisoning symptoms. Yet because of its proven ability to cause a serious type of blood disease in some animals — Heinz body anemia — propylene glycol has been banned by the FDA for use in cat food. Large doses and unusual circumstances are necessary for the development of propylene glycol toxicity. Many dog owners know that antifreeze is poisonous to dogs, but not all people understand how dangerous antifreeze poisoning can really be.Unfortunately, exposure to even a small amount of toxic antifreeze can quickly lead to death. Toxicity and death may occur after drinking even a small amount.
