Ethylene glycol is a colorless, odorless, sweet-tasting chemical. [9] Once kidney failure develops, the prognosis is poor. Ethylene glycol monobutyl ether (EGBE) (2-Butoxyethanol) - removed from the list of hazardous air pollutants (glycol ethers category) in November 2004 - Federal Register - November 29, 2004 (69 FR 69320). Trends in toxic alcohol exposures in the United States from 2000 to 2013: a focus on the use of antidotes and extracorporeal treatments. "[12] Since 1994, federal airports must comply with the Glycol Guidelines of the Canadian Environmental Protection Act, monitoring and reporting on concentrations of glycols in surface water. [65] In the United States, eight states (Oregon, California, New Mexico, Virginia, Arizona, Maine, Tennessee, Washington) have made the addition of bittering agents to antifreeze compulsory. [35] Ipecac-induced vomiting is not recommended. [78], CS1 maint: DOI inactive as of December 2020 (. of 50% ethylene glycol for an 80 kg adult and 56 mL (2 oz.) Ethylene glycol is a toxic compound. [24][36][37] Fomepizole has been shown to be highly effective as an antidote for ethylene glycol poisoning. [7] Urine microscopy can reveal needle or envelope-shaped calcium oxalate crystals in the urine which can suggest poisoning; although these crystals may not be present until the late stages of poisoning. Because hemodialysis will also remove the antidotes from the blood, doses of antidotes need to be increased to compensate. USA.gov. [37][38], Adjunct agents including thiamine and pyridoxine are often given, because they may help prevent the formation of oxalic acid. Ethylene oxide gas is toxic, carcinogenic, and very explosive. Ng PCY, Long BJ, Davis WT, Sessions DJ, Koyfman A. Intern Emerg Med. Ingestion of this liquid can lead to shock or even death. [61][62] However, these numbers may underestimate actual numbers because not all cases attributable to ethylene glycol are reported to poison control centers. It and its toxic byproducts first affect the central nervous system (CNS), then the heart, and finally the … [12] It is also used in manufacturing polyester products. [1], Ethylene glycol is a colorless, odorless, sweet liquid, commonly found in antifreeze. Treasure Island (FL): StatPearls Publishing; 2020 Jan. 2020 Jun 26. The primary danger is its sweet taste, so children and animals can eat it, and it is toxic. Ethylene glycol poisoning is poisoning caused by drinking ethylene glycol. Toxic Exposure to Ethylene Oxide Results in Lawsuits. [1] Long term outcomes may include kidney failure and brain damage. As the metabolism of ethylene glycol progresses there will be less ethylene glycol and this will decrease the blood ethylene glycol concentration and the osmolal gap making this test less useful. In an effort to prevent poisoning, often a bittering agent called denatonium benzoate, known by the trade name Bitrex, is added to ethylene glycol preparations as an adversant to prevent accidental or intentional ingestion. 28). The alleged exposure may be erroneous. [72] Numerous cases of poisoning have been reported since then, and it has been shown to be toxic to humans. The bittering agent is thought to stop ingestion as part of the human defense against ingestion of harmful substances is rejection of bitter tasting substances. The U.S. Environmental Protection Agency generally puts substances which are lethal at more than 30 g to adults in Toxicity Class III. [58][59] Children or animals may be exposed by accidental ingestion; children and animals often consume large amounts due to ethylene glycol having a sweet taste. The management of severe toxic alcohol ingestions at a tertiary care center after the introduction of fomepizole. Get the latest public health information from CDC: https://www.coronavirus.gov, Get the latest research information from NIH: https://www.nih.gov/coronavirus, Find NCBI SARS-CoV-2 literature, sequence, and clinical content: https://www.ncbi.nlm.nih.gov/sars-cov-2/. [21] There may be a slight risk of poisoning where mists or fogs are generated, although this rarely leads to poisoning as ethylene glycol causes irritation and coughing when breathed in, alerting victims to its presence. Epub 2014 Apr 9. Traditionally, gastric lavage or nasogastric aspiration of gastric contents are the most common methods employed in ethylene glycol poisoning. Jun 26, Methanol Toxicity. [14] Accumulation of glycolic acid in the body is mainly responsible for toxicity. People therefore must be monitored in an intensive care unit. [52] In Australia there were 17 cases reported to the Victorian poison center and 30 cases reported to the New South Wales poison center in 2007. [1] Later symptoms may include a decreased level of consciousness, headache, and seizures. [2] Hemodialysis may also be used in those where there is organ damage or a high degree of acidosis. [2] The preferred antidote is fomepizole with ethanol used if this is not available. Although survival with medical treatment has occurred with doses much higher than this, death has occurred with 30 mL of the concentrate in an adult. Please enable it to take advantage of the complete set of features! NLM [1] Diagnosis may be confirmed by measuring ethylene glycol levels in the blood; however, many hospitals do not have the ability to perform this test. The substance may be toxic to kidneys, liver, centr al nervous system (CNS). As ethylene glycol is rapidly absorbed, gastric decontamination is unlikely to be of benefit unless it is performed within 60 minutes of ingestion. As activated charcoal does not adsorb glycols, it is not recommended as it will not be effective at preventing absorption. [7], Fomepizole is a potent inhibitor of alcohol dehydrogenase; similar to ethanol, it acts to block the formation of the toxic metabolites. Ethylene oxide is used especially in the synthesis of ethylene glycol and as a sterilizing agent for medical supplies and foods, as a fumigant and as an insecticide. [51][52][53][54] Human poisoning often occurs in isolated cases, but may also occur in epidemics. Ethylene oxide (EO) is an environmental pollutant and is toxic to humans. Ethylene | CH2=CH2 or (C2H4)n or C2H4 | CID 6325 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards/toxicity information, supplier lists, and more. [9], Generally, if the person is treated and survives then a full recovery is expected. Treasure Island (FL): StatPearls Publishing; 2020 Jan–. [68] Similarly, White found that adding bittering agents did not decrease the frequency or severity of antifreeze poisonings in children under the age of 5. [7] The usefulness of gastric lavage has, however, been questioned, and it is now no longer used routinely in poisoning situations. 245). It is eventually excreted in the urine, but supportive therapy for the CNS depression and metabolic acidosis will be required until the ethylene glycol concentrations fall below toxic limits. I-3). Similar to ethanol, it causes intoxication, followed by drowsiness or coma. Ethylene vinyl acetate is a type of plastic — a polymer with a wide variety of uses, both residential and industrial. [10][24] Often both antidotal treatment and hemodialysis are used together in the treatment of poisoning. [7][8], The most common source of ethylene glycol is automotive antifreeze or radiator coolant, where concentrations are high. [7] It is only used in the presence of a toxic dose of another poison or drug. [77] A report in 2000 stated that ethylene glycol was becoming less popular for aircraft deicing in the U.S., due to its reporting requirements and adverse environmental impacts (p. 213), and noted a shift to the use of propylene glycol (p. Ethylene oxide is a gas that is used in many countries for the disinfection of heat-sensitive foodstuffs. Toxic Inhalation of Ethylene Glycol: A Pharmacological Improbability To the Editor: Poison center specialists and medical toxicologists are often confronted with unusual exposures or exposure histories. However, it is very useful as a chemical and can be found in many household items such as detergents, cosmetics, etc. The first to form is glycolic acid which is further oxidised to oxalic acid. A similar result was found in Michigan when the state analyzed the population near a … [5] Antifreeze products sometimes have a substance to make it bitter added to discourage drinking by children and other animals but this has not been found to be effective. In cats, this stage occurs 12–24 hours after consuming antifreeze; in dogs, at 36–72 hours after consuming antifreeze. In: StatPearls [Internet]. [77] Airports that discharge the collected aircraft deicing fluid directly to waters of the U.S. must also meet numeric discharge requirements for chemical oxygen demand. [24], In addition to antidotes, an important treatment for poisoning is the use of hemodialysis. [60] In the United States there were 5816 cases reported to poison centers in 2002. Ethylene glycol in itself is not 1993 Jul-Sep;3(3):277-84. [7] The central nervous system is affected early in the course of poisoning as the result of a direct action of ethylene glycol. 2014 Jul-Aug;27(4):395-401. doi: 10.1111/sdi.12237. [17] People who develop severe central nervous system manifestations or stroke who survive may have long term neurologic dysfunction; in some cases they may recover, although convalescence may be prolonged. The primary treatments are either ethanol or fomepizole and, occasionally, dialysis. In smaller amounts, ethylene oxide is used as a pesticide and a sterilizing agent. Ethylene glycol toxicity is a type of toxic leukoencephalopathy.Ethylene glycol, best known as a component of antifreeze, has been ingested both deliberately and accidentally, resulting in … Caprolactam – removed from the list of hazardous air pollutants in June 1996 - Federal Register - June 18, 1996 (61 FR 30816). [22] Ethylene glycol is not well absorbed through skin meaning poisoning following dermal exposure is also uncommon. Ethylene glycol is chemically broken down in the body into toxic compounds. Ethylene is used as an anesthetic, a refrigerant, and to make other chemicals as polymers and plastics. It has been shown to be highly effective in the removal of ethylene glycol and its metabolites from the blood. Acta Medica (Hradec Kralove). As it has a toxic effect and, in high doses, can cause seizures and even coma, it has not been authorised for use in the food industry in Europe since 1981. [1] It may be drunk accidentally or intentionally in a suicide attempt. [7] Seizures may occur due to a direct effect. Ethylene glycol may be swallowed accidentally, or it may be taken deliberately in a suicide attempt or as a substitute for drinking alcohol (ethanol). Ethylene is not toxic, but is a simple asphyxiant. [73] Another study found the toxicity to aquatic and other organisms was relatively low, but the oxygen-depletion effect of biodegradation was more serious (p. Chronic (long-term) exposure to EtO in humans can cause irritation of the eyes, skin, nose, throat, and lungs, and damage to … Congress classified it as a “hazardous air pollutant,” according to the … Its adverse effects include intoxication, hypoglycemia in children, and possible liver toxicity. He continued his work with the compound and eventually … [28] Additionally, the presence of other alcohols such as ethanol, isopropanol, or methanol or conditions such as alcoholic or diabetic ketoacidosis, lactic acidosis, or kidney failure may also produce an elevated osmolal gap leading to a false diagnosis. [24] Intubation and respiratory support may be required in severely intoxicated people; people with hypotension require treatment with intravenous fluids and possibly vasopressors. [44] Less commonly it has been used as a means of homicide. If antifreeze is placed in toilets, ensuring the lid is down and the door closed. Because ethanol has a much higher affinity for alcohol dehydrogenase, about a 100-times greater affinity, it successfully blocks the breakdown of ethylene glycol into glycolaldehyde, which prevents the further degradation. Ethylene Glycol is a common component of engine coolant, or antifreeze. These toxic substances also affect the cardiopulmonary system and can cause renal failure. [7] In this situation a helpful test to diagnose poisoning is the measurement of the osmolal gap. https://en.wikipedia.org/w/index.php?title=Ethylene_glycol_poisoning&oldid=996426608, Toxic effects of substances chiefly nonmedicinal as to source, CS1 maint: DOI inactive as of December 2020, Articles with dead external links from September 2017, Articles with permanently dead external links, Short description is different from Wikidata, Articles with unsourced statements from July 2019, Articles lacking reliable references from October 2012, Wikipedia articles needing clarification from March 2012, Wikipedia medicine articles ready to translate, Creative Commons Attribution-ShareAlike License, Stage 1 (30 minutes to 12 hours) consists of. [9] Some people put antifreeze into their cabin's toilet to prevent it from freezing during the winter, resulting in toxicities when animals drink from the toilet. [46][47][48][49] The most significant long-term complication is related to the kidneys. [75] Detailed mitigation plans include storage and handling issues (p. 27), spill response procedures, and measures taken to reduce volumes of fluid (p. The disadvantage of fomepizole is that it is expensive. [73] The process of biodegrading of glycols also increases the risk to organisms, as oxygen levels become depleted in surface waters (p. Repeated or prolonged exposure to the substance can produce targe t organs [74], Once kidney failure has developed in dogs and cats, the outcome is poor. Exposures are generally observed due to accidental or intentional ingestions, with its sweet taste lending to accidental toxic exposures, whereas intentional exposures may be motivated by suicide attempt or desire for inebriation in the absence of ethanol. [64][68][69] Specifically, Mullins finds that bittering of antifreeze does not reduce reported cases of poisoning of preschoolers in the US state of Oregon. 2010;53(1):19-23. It is the simplest alkene (a hydrocarbon with carbon-carbon double bonds).. The term “toxic alcohols” is a collective term that includes methanol, ethylene glycol, and isopropyl alcohol. Ethylene glycol, hazardous substance in the household. [2] Other treatments may include sodium bicarbonate, thiamine, and magnesium. [7] That is approximately 224 mL (7.6 oz.) Hemodialysis is usually indicated in people with severe metabolic acidosis (blood pH less than 7.3), kidney failure, severe electrolyte imbalance, or if the person's condition is deteriorating despite treatment. [9] The treatment is generally the same, although vodka or rectified spirits may be substituted for pharmaceutical grade ethanol in IV injections. [1] Early symptoms include intoxication, vomiting and abdominal pain. [10] The toxic mechanism of ethylene glycol poisoning is mainly due to the metabolites of ethylene glycol. [12] In 2006, approximately 1540 kilotonnes of ethylene glycol were manufactured in Canada by three companies in Alberta, with most of the production destined for export. Initially it is metabolized by alcohol dehydro… Although a naturally occurring plant hormone, ethylene can be dangerous, especially when handled incorrectly. -, Jacobsen D, Hewlett TP, Webb R, Brown ST, Ordinario AT, McMartin KE. 13). [7] Both antidotes have advantages and disadvantages. [15], Ethylene glycol has been shown to be toxic to humans[16] and is also toxic to domestic pets such as cats and dogs. [44] People who present early to medical facilities and have prompt medical treatment typically will have a favorable outcome. However, a normal osmolar gap does not rule out ethylene glycol exposure because of wide individual variability. 2007 Sep;25(7):799-803. doi: 10.1016/j.ajem.2007.01.017. National Center for Biotechnology Information, Unable to load your collection due to an error, Unable to load your delegates due to an error. Precautions must be taken to avoid any equipment, tools, etc., that may spark in the vicinity of EO chambers. Pharmaceutical grade ethanol is usually given intravenously as a 5 or 10% solution in 5% dextrose, but it is also sometimes given orally in the form of a strong spirit such as whisky, vodka, or gin. 12). [7] The increase in metabolites may cause encephalopathy or cerebral edema. It’s rare, but it’s real. 1988 Jan;84(1):145-52. StatPearls [Internet] StatPearls Publishing; Treasure Island (FL): 2020. HHS Costing US$1,000 per gram, an average course used in an adult poisoning would cost approximately $3,500 to $4,000. -. [3] Those affected are often adults and male. In fact, one comprehensive lifetime exposure study of workers in ethylene oxide production facilities found no statistically significant excess cancer risk due to ethylene oxide exposure. Post harvest handlers must do everything they can to maintain the best possible environmental conditions for those delicate parcels. COVID-19 is an emerging, rapidly evolving situation. Toxic alcohol diagnosis and management: an emergency medicine review. [2] When broken down by the body it results in glycolic acid and oxalic acid which cause most of the toxicity. In: StatPearls [Internet]. Stage 2 (12 to 36 hours) where signs of "alcohol" poisoning appear to resolve, underlying severe internal damage is still occurring. Ethylene glycol (C2H6O2) is a toxic alcohol that is found in various household and industrial agents. This site needs JavaScript to work properly. Storing antifreeze in clearly marked original sealed containers, in areas that are inaccessible to pets. -, Driver J, Tardiff RG, Sedik L, Wester RC, Maibach HI. [70] An online veterinary manual provides information on lethal doses of ethylene glycol for chicken, cattle, as well as cats and dogs, adding that younger animals may be more susceptible.  |  This page was last edited on 26 December 2020, at 15:11. [7] People presenting with metabolic acidosis or seizures require treatment with sodium bicarbonate and anticonvulsives such as a benzodiazepine respectively. [29] Finally, many commercial radiator antifreeze products have fluorescein added to enable radiator leaks to be detected using a Wood's lamp.
