Penumarthy L, Oehme FW. Clin Chem. Fomepizole treatment should be initiated immediately when ethylene glycol poisoning is suspected. Antifreeze consumed as concentrated solution. THOMAS E. ARCHIE, M.D., is in private practice at Inner Health, Fort Collins, Colo. McMartin KE, Johansen KS, McMartin KE. These 95% commercial antifreeze preparations are diluted ~50% with water when used in vehicle cooling systems. t contributor in patients with metabolic acidosis of unknown cause and subsequent renal failure. Litovitz TL, If metabolic acidosis persists, too little ethanol or fomepizole is being administered. 1998 annual reportof the American Association of Poison ControlCenters Toxic Exposure Surveillance System. Ad Hoc Committee. For institutions that frequently treat ethylene glycol toxicity cases, in-hospital rapid laboratory confirmation may become cost-effective because of the institutional cost-benefit ratio evaluation that compares therapy with fomepizole, ethanol, and hemodialysis. Do not send gel tubes or serum from gel tubes as they interfere with analysis. et al. New treatment for ethylene glycolpoisoning. Jacobsen D, 1997 annual report of the American Association of Poison Control Centers Toxic Exposure Surveillance System. Therapy with 100 mg of intravenous thiamine would be appropriate if ethanol withdrawal is suspected.4 Parenteral calcium, given as gluconate or chloride salts, may be necessary for treatment of tetany and seizures caused by hypocalcemia.5,6,8, Pyridoxine (vitamin B6) and thiamine (vitamin B1) in dosages of 100 mg daily are believed to promote the conversion of intermediate byproducts into nontoxic metabolites,3,5,6,9 but clinical data supporting their effectiveness do not exist. Antizol (fomepizole). 2018 Apr;13(3):375-383. doi: 10.1007/s11739-018-1799-9. Crouch B, 9th ed. Q&A: Ethylene Glycol Toxicity Diagnosis and Treatment. While ethylene glycol itself causes intoxication, the accumulation of toxic metabolites is responsible for the potentially fatal acidosis and renal failure, which characterises ethylene glycol poisoning. Glycolatekinetics and hemodialysis clearance in ethylene glycol poisoning. Kerns W II, Tidsskr Nor Laegeforen. Youniss J, An increased anion gap with a normal chloride concentration indicates retention of nonvolatile organic acids such as glycolic acid.5–7,9 The osmolar gap (Og) is calculated by subtracting the calculated serum osmolality (Oc) from measured osmolality (Om), or Og = Om − Oc (Table 2). Hypertension, tachycardia, and cardiac failure may ensue. Burkhart KK, Ethylene glycol can be recovered from the natural gas and reused as an inhibitor after purification treatment that removes water and inorganic salts. Ethylene glycol intoxication following brake fluid ingestion complicated with unilateral facial nerve palsy: a case report. Individuals intentionally consume ethylene glycol, usually in the form of antifreeze, as an inexpensive alcohol substitute or as a suicidal agent. Ad Hoc Committee. Laboratory testing inethanol, methanol, ethylene glycol, and iso-propanol toxicities. META Study Group. Don't miss a single issue. Traditionally, gastric lavage or nasogastric aspiration of gastric contents are the most common methods employed in ethylene glycol poisoning. Krenzelok EP, Philadelphia, Pa.: Saunders;1990:697. Like ethanol, fomepizole inhibits alcohol dehydrogenase; however it does so without producing serious adverse effects. 1999;37(5):537-60; Levine M, Curry SC, Ruha AM, et al. Basnayake BMDB, Wazil AWM, Nanayakkara N, Mahanama RMBSS, Premathilake PNS, Galkaduwa KKMCDK. Brown ST, 13. Ethylene glycol, the predominant constituent of automotive products such as antifreeze and deicers, is an important but uncommon toxicological problem in current medical practice (1)(2). The purpose of the present case report was to demonstrate 4-MP efficiency in EG poisoning in a 4-year-old child. He received his medical degree from the University of North Carolina School ofMedicine, Chapel Hill traditional ethanol treatment, advantages of fomepizole include lack of depression of the central, Address correspondence to Robert D. Scalley, Pharm.D., 3017 Parkview Ct., Fort Collins, CO 80525 (e-mail:rds@libra.pvh.org). Caravati EM, However, ethanol therapy is complicated by its own inherent toxicity, and the need to carefully monitor serum ethanol concentrations and adjust the rate of administration. Krenzelok EP, Ovrebo S, Historically, this has been done with intoxicating … Treatment mirrors this. Witting MD. 1981 Nov;38(11):724-6 AACT Criteria for Treatment of Ethylene Glycol Poisoning with an Antidote, All doses should be administered as a slow intravenous infusion over 30 minutes, Fomepizole treatment is continued until ethylene glycol levels have been reduced below 20 mg per dL (3 mmol per L). The authors indicate that they do not have any conflict of interest. Frommer JP, Ethylene glycol elimination kinetics and outcomes in patients managed without hemodialysis. Hamilton RS, Aabakken L, This material may not otherwise be downloaded, copied, printed, stored, transmitted or reproduced in any medium, whether now known or later invented, except as authorized in writing by the AAFP. -. New York: McGraw-Hill, Health Professions Division, 1996:1682–3. Following ingestion, ethylene glycol is first hepatically metabolised to glycoaldehyde by alcohol dehydrogenase. Treatment options for ethylene glycol toxicity include supportive care, fomepizole (Antizole, 4-Methylpyrazole or 4MP), ethanol, dialysis and theoretically, thiamine, pyridoxine and magnesium. Laboratory. Acute ethylene glycolintoxication. Am J Nephrol. 1982;2:1–5. Frommer JP, Get Permissions, Access the latest issue of American Family Physician. Symptoms of ethylene glycol toxicity include confusion, ataxia, hallucinations, slurred speech, and comaSymptoms are most severe six to 12 hoursafter ingestion, when the acidic metabolites ofethylene glycol are at their maximal concentrationThe presentation may be similar toethanol intoxication, if the patient presentsearly or has consumed small amounts of ethyleneglycol.
