DEG is less toxic than ethylene glycol in most species, but more toxic than propylene glycol. Three stages of poisoning can be seen with ethylene glycol: 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. 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. 2 – 11 The most recent mass DEG poisoning occurred in India in 1998. “Propylene glycol ingested at toxic doses can cause central nervous system depression and lactic acidosis, Brutlag says. Propylene glycol poisoning, acetaminophen, vitamin K, or benzocaine toxicity symptoms are similar to chives poisoning symptoms. Fomepizole (Antizol-Vet®, 4-methylpyrazole) is the treatment of choice for ethylene glycol poisoning in dogs. Dogs rely on these bacteria for a healthy immune system and a balanced pH level. The oral LD 50 of PG in dogs is ~9 mL/kg. Antifreeze. Antifreeze can be extremely dangerous to dogs. 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. Later symptoms may include a decreased level of consciousness, headache, and seizures. Ethylene glycol poisoning is poisoning caused by drinking ethylene glycol. 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. Long term outcomes may include kidney failure and brain damage. The oral median lethal dose (LD50) of propylene glycol in dogs has been reported to be ~9 ml/kg body weight. 2 Ethylene glycol is most commonly found in automotive antifreeze and is also used as a precursor to industrial polymers. All animals are susceptible, with dogs and cats being affected most often. Antifreeze is an engine coolant. Ethanol is the treatment of choice for cats and is administered for up to 64 hours. When dogs or cats are exposed to a toxic dose of ethylene glycol, immediate treatment is necessary. 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. 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.) Underlying renal insufficiency and hepatic dysfunction raise risk for toxicity. AU - Claus, Melissa A. 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. 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. Ethylene Glycol (Antifreeze) Poisoning Basics OVERVIEW • Results from ingesting substances containing ethylene glycol (such as antifreeze) • Common in small animals (such as dogs and cats) • Highest fatality rate of all poisons; fatality rates higher for cats than dogs Some “pet-safe” antifreeze products contain propylene glycol, which is much safer than ethylene glycol if ingested. According to vetinfo.com, antifreeze poisoning in dogs and cats is the most common form of poisoning in the United States. Most intoxications are associated with ingestion of antifreeze, which is typically 95% EG. Propylene glycol toxicity is metabolized to compounds that are normal constituents of the citric acid cycle. Containing two alcohol groups, it is classed as a diol.It is miscible with a broad range of solvents, including water, acetone, and chloroform.In general, glycols are non-irritating and have very low volatility. Antifreeze poisoning is the most common poisoning of dogs and cats in the United States. 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 is especially dangerous since it only takes about 3oz to poison a medium-sized dog. Antifreeze poisoning in dogs is a very serious matter. Request PDF | Propylene glycol intoxication in a dog | To describe the clinical course, treatment, and outcome of a dog with propylene glycol intoxication. It has occasionally been substituted for propylene glycol in pharmaceutical preparations, resulting in the deaths of more than 100 persons in some incidents. All animals are susceptible to ethylene glycol (EG) toxicity, but it is most common in dogs and cats. It is believed that background concentrations of ethylene glycol in air, soil, surface and groundwater do not lead to poisoning. Antifreeze Toxicity in Dogs. Early symptoms include intoxication, vomiting and abdominal pain. Experimentally, propylene glycol administration in dogs at 2 g/kg/day has caused no adverse effects.” Propylene glycol is an effective alternative to ethylene glycol and the FDA has recently labeled propylene glycol safe. 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. 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. AU - Poppenga, Robert H. PY - 2011/12. N2 - Objective: To describe the clinical course, treatment, and outcome of a dog with propylene glycol intoxication. Until 1996, almost no data existed on the incidence of ethylene glycol (antifreeze) poisoning. If cats or dogs ingest large amounts of propylene glycol, poisoning can occur.. Therefore, now the ethylene glycol has been replaced with propylene glycol. Antifreeze poisoning in dogs. With the increasing popularity of e-cigarettes, comes an increased risk of poisoning in dogs whose owners use them. Zinc, copper, and naphthalene poisoning are other types that will need to be ruled out. 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. 4-MP) — because they have discontinued production of the drug. Symptoms of Chemical poisoning - Propylene Glycol including 10 medical symptoms and signs of Chemical poisoning - Propylene Glycol, alternative diagnoses, misdiagnosis, and correct diagnosis for Chemical poisoning - Propylene Glycol signs or Chemical poisoning - Propylene Glycol symptoms. Prevention is key. In cats, ingestion of a diet containing 6%–12% PG can result in Heinz body formation and decreased RBC survival. These 95% commercial antifreeze preparations are diluted ~50% with water when used in vehicle cooling systems. Automotive antifreeze kills 10, 000 of these pets every year. Toxicity and death may occur after drinking even a small amount. 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. However, propylene glycol is considerably safer (less toxic) than its far more dangerous cousin — ethylene glycol. Propylene glycol products are biodegradable, anti-corrosive, and recyclable. Ingestion of ethylene glycol (EG) is a frequently encountered toxicity in dogs and cats. It is best to keep the story about antifreeze poisoning simple—put simply, it kills. 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. 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. Toxic ef … Sadly, most manufacturers don’t know about all the research being done into polyethylene glycol and its derivatives. The ingredient found in antifreeze that is poisonous to dogs and cats, is ethylene glycol, which make up 95 percent of the antifreeze. It is the best thing you can do to prevent poisoning in your pets however, it does not eliminate it from guests and neighbors. 12 Almost all (98%) affected children died in a 1996 epidemic in Haiti. While propylene glycol antifreeze is more expensive, it’s safe for pets and other wildlife, so please consider using this instead. Tufts Veterinary Newsletter reported that a medium-sized dog would have to ingest about 20 ounces of propylene glycol before getting seriously ill. 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. Propylene glycol is a controversial additive used to help preserve the moisture content in some commercial dog foods. Experts note that factors that affect the risk of poisoning when exposed to ethylene glycol include its dose, duration and nature of contact. 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. T1 - Propylene glycol intoxication in a dog. Share this support centre article. Dr. Hotchkiss says that what makes ethylene glycol such a dangerous and common form of poisoning is that the toxin’s sweet smell and taste appeals to an animal’s sweet tooth. It is given intravenously for 36 hours, and stops the metabolism of ethylene glycol into its damaging metabolites. Antifreeze products will mostly contain Ethylene glycol, Propylene glycol or … Although it is considered safe, large intravenous doses given over a short period of time can be toxic. Over 10,000 dogs and cats are poisoned with automotive antifreeze each year. This is most commonly seen when pets ingest liquid, high concentration propylene glycol … If the above wasn’t enough, polyethylene glycol also destroys the beneficial bacteria found on your dog’s skin and inside their stomachs. The most toxic kind contains ethylene glycol, but some contain methanol or propylene glycol, which may not be as toxic but can still make your dog unwell. Antifreeze poisoning in dogs is a very serious matter. It is a colorless, odorless, and sweet-tasting solution. Is antifreeze dangerous to dogs?
