There is no known exposure to drugs, medications, toxins, compost, garbage, etc. Diagnosis is often difficult because the nonspecific multisystemic signs may appear similar to other types of CNS disease or trauma, gastroenteritis, pancreatitis, ketoacidotic diabetes mellitus, and acute renal failure due to renal ischemia or other nephrotoxicants. Ethylene glycol, a sweet-tasting, odorless liquid, is the active ingredient in most automotive antifreeze products. EG is rapidly absorbed from the GI tract; in dogs, blood concentrations of EG peak within 3 hr of ingestion. Oxalate also combines with calcium to form a soluble complex that is excreted via glomerular filtration. Calcium oxalate crystals form within the lumina of tubules as water is reabsorbed from the glomerular filtrate and the pH decreases (smaller numbers of calcium oxalate crystals may also be observed in the adventitia of blood vessel walls throughout the body). verify here. *Pet Poison Helpline, is an animal poison control service available 24 hours, seven days a week for pet owners and veterinary professionals who require assistance treating a potentially poisoned pet. Glycolaldehyde is then rapidly metabolized to glycolic acid. This damage can be identified in a serum biochemistry profile by increases in the levels of creatinine and BUN (blood urea nitrogen) that are normally removed from the blood by the kidneys. Ethylene glycol (EG) poisoning is common in dogs and cats 1 – 4 and often results in death if it is not diagnosed and treated promptly. Dogs like sweet things. Ethylene glycol also forms acidic chemicals in the body, which can change the body's acid/base balance and affect your nervous system, lungs, and heart,” a … How do dogs get ethylene glycol poisoning? Contributors: Kristiina Ruotsalo, DVM, DVSc, Dip ACVP & Margo S. Tant BSc, DVM, DVSc & Ahna Brutlag, DVM, MS, DABT, DABVT, Veterinarian approved Preventive Care products. Incoordination, excessive urination, excessive thirst, vomiting, and lethargy are amongst the first signs to appear. Poultry usually do not develop gross lesions. Untreated, antifreeze poisoning can be fatal to pets. During this stage, severe kidney failure is developing secondary to calcium oxalate crystals forming in the kidneys. EG concentrations in serum and urine are detectable by 1–2 hr after ingestion. A dog with ethylene glycol poisoning might suddenly start peeing every couple of minutes, or might develop urinary incontinence and have trouble "holding it." Within 30 minutes of ingestion, they may resemble a person who has had too much to alcohol drink. Pigs may also have pulmonary edema with tan fluid in the pleural and peritoneal cavities. Left untreated, the animal may die. A urinalysis may also confirm ethylene glycol poisoning and underlying kidney damage by the presence of dilute urine containing blood, protein, cellular casts (plugs of cells which have taken the shape of dying tubules in the kidneys), and calcium oxalate crystals (which are seen with ethylene glycol poisoning). Max has no prior history of seizures to the owners’ knowledge, but they have owned him for only three months. Fomepizole is a new agent with a specific indication by the U.S. Food and Drug Administration for the treatment of ethylene glycol poisoning.4, 6, 7, … Common clinical signs were ataxia, depression, vomiting, and hypothermia. Fomepizole is expensive but life-saving when administered to dogs within the first 8-12 hours of ingestion. Even a small amount of antifreeze can be fatal to dogs and cats. Epistaxis and hemoglobinuria have also been seen in cattle that have ingested large doses of EG. If ingestion of EG is not witnessed, diagnosis is usually based on a combination of history, physical examination, and laboratory data. In colder climates, the incidence of EG intoxications is seasonal, with most cases occurring in the fall, winter, and early spring, when antifreeze is added to radiator fluid or when cooling systems are flushed. Calif Vet 52, 18-22. Stage 1: This occurs within 30 minutes to 12 hours and looks similar to alcohol poisoning. This depression appears similar to ethanol intoxication, but without the characteristic odor of alcohol. Poultry may become drowsy, ataxic, dyspneic, and recumbent; torticollis, ruffled feathers, and watery droppings are also seen. Oliguric acute renal failure usually develops between 12 and 24 hr in cats and between 36 and 72 hr in dogs. Dogs may be attracted to ethylene glycol by its sweet taste. Stage 3 - (36-72 hours after ingestion): At this stage, signs of severe kidney dysfunction, which is characterized by swollen, painful kidneys and the production of minimal to no urine, may occur. Part II. Progressive depression, lethargy, lack of appetite, vomiting, seizures, coma, and death may be seen. Cutaneous absorption from topical products that contain EG has been reported to cause toxicity in cats. Antifreeze Poisoning in Dogs & Cats (Ethylene Glycol Poisoning) During certain times of the year (such as summer and winter), dogs and cats are more exposed to antifreeze. Characteristic alterations in the hemogram and serum chemical profile included neutrophilia, lymphopenia, azot … Dogs may be attracted to ethylene glycol by its sweet taste. Its concentration in automotive radiator fluid is high (95%), a source to which pets (dogs and cats) have easy access. Cattle may become depressed, tachypneic, and ataxic, and develop paraparesis or recumbency. Studies were made prior to and after ingestion on an hourly basis over a period of 8 to 10 hours. The dose of 4-MP (5% solution [50 mg/mL]) is 20 mg/kg body wt, IV, initially, followed by 15 mg/kg, IV, at 12 and 24 hr, and 5 mg/kg, IV, at 36 hr. In cats, 4-MP is ineffective at the canine dosage, and either a higher, extra-label dosage (125 mg/kg initially, followed by 31.3 mg/kg at 12, 24, and 36 hr after the initial dose) or ethanol is used. Emergency Situations, Treatment, Pet Services. Wobbly, uncoordinated movement 4. We’re committed to keeping clients and staff safe during COVID-19 with NEW admittance and check-out processes. Whereas all animal species are susceptible, to ethylene glycol toxicity, cats … Car radiator coolant is the most dangerous because it can be made up entirely of ethylene glycol. Antifreeze poisoning occurs when pets drink antifreeze containing ethylene glycol. However, these types of tests may not be as accurate, and false positives can be seen (for instance, false positives may occur from products with similar chemical structures such as propylene glycol, glycerol, mannitol, isopropyl alcohol, sorbitol, etc.). In addition, antifreeze may be ingested by way of intentional poisoning or because it is the only available liquid in cold weather. Further absorption of EG is prevented by induction of emesis or gastric lavage (or both) within 1–2 hr of ingestion, although the rapidity of EG absorption from the GI tract suggests these procedures may not be beneficial. As … Glyoxylic acid is rapidly metabolized to formic acid, carbon dioxide, glycine, serine, and oxalate. Commercial formulations of 4-MP are available. The first of two rate-limiting biotransformation steps is the production of glycoaldehyde from EG by the enzyme alcohol dehydrogenase. Ethylene glycol has a very narrow margin of safety – which means only a tiny amount can result in severe poisoning. The minimum lethal dose of undiluted EG is 1.4 mL/kg body wt in cats, 4.4 mL/kg in dogs, 7–8 mL/kg in poultry, and 2–10 mL/kg in cattle. Excessive urination 6. The acronym SLUD stands for salivation, lacrimation, urination, and defecation, which are the clinical signs associated with muscarinic cholinergic overstimulation caused by certain toxins. The poison primarily affects the kidneys and can do irreversible damage. However, during this stage, dogs become dehydrated, and develop an elevated breathing and heart rate. Please confirm that you are a health care professional. Even if you only suspect that your dog has ingested ethylene glycol, if the dog is showing all of the effects of ethylene glycol toxicity, and the substance is accessible in any way, you should take your dog to be checked. Ethylene glycol itself is not toxic, but it is metabolized in the animal's body to several extremely toxic chemicals that are responsible for its potentially lethal effects. Many animals will voluntarily drink ethylene glycol if antifreeze is spilled or leaks onto garage floors or driveways. Comp Contin Educ Pract Vet 21 (12), 1124-1133 VetMedResource. Coma This testing method is very accurate, but not always available in the middle of the night. Calcium oxalate crystalluria may be observed as early as 3 and 6 hr after ingestion in cats and dogs, respectively. Propylene glycol poisoning in dogs is caused by ingesting propylene glycol. Ethylene glycol, a sweet-tasting, odorless liquid, is the active ingredient in antifreeze. Stage 1:  (within 30 minutes of ingestion): The signs include lethargy, vomiting, incoordination, excessive urination, excessive thirst, hypothermia (low body temperature), seizures, and coma. Diarrhea 7. The liver quickly breaks down ethylene glycol into toxic products that can lead to kidney failure and death. This chemical is extremely toxic to dogs and is also very sweet so they like the taste. Within 3 hr of ingestion of toxic doses of EG, dogs and cats develop normochloremic metabolic acidosis with an increased anion gap, minimally concentrated or isosthenuric urine with an acidic pH, and marked serum hyperosmolality with an increased osmolal gap. Signs include lethargy, anorexia, dehydration, vomiting, diarrhea, oral ulcers, salivation, tachypnea, and possibly seizures or coma. 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 … • Dogs treated less than 5 hours following ingestion of ethylene glycol—prognosis is excellent with fomepizole treatment • Dogs treated up to 8 hours following ingestion of ethylene glycol—most recover • Dogs treated up to 36 hours following ingestion of ethylene glycol—may benefit from prevention of … Signs of SLUD are most consistent with exposure to which of the following classes of chemicals? Ethylene glycol has a very narrow margin of safety – which means only a tiny amount can result in severe poisoning. Learn more. The signs that the antifreeze poisoning in dogs has proceeded to severe levels include the presence of excess urea levels and other nitrogenous waste in the kidney and blood. Seizures/Convulsions/Shaking tremors 11. Gaynor A R et al (1999) Acute Ethylene Glycol Intoxication.
