John T VanDeVoort, PharmD Regional Director of Pharmacy, Sacred Heart and St Joseph's Hospitals [Guideline] Caravati EM, Erdman AR, Christianson G, Manoguerra AS, Booze LL, Woolf AD, et al. National Institute on Aging. ATSDR. http://www.merckmanuals.com/professional/special-subjects/recreational-drugs-and-intoxicants/alcohol-toxicity-and-withdrawal. Here's what to do: It can be difficult to decide if you think someone is drunk enough to warrant medical intervention, but it's best to err on the side of caution. Hypocalcemia can ensue, and cause coma, seizures, and dysrhythmias. Ethanol (or ethyl alcohol) and isopropanol (or isopropyl alcohol) are two alcohols that can be safely and effectively used to sanitize hands and to disinfect surfaces. Fomepizole and ethanol are potent inhibitors of alcohol dehydrogenase and reduce generation of toxic metabolites. Diseases & Conditions, 2010 Brent J. Fomepizole for ethylene glycol and methanol poisoning. Perinatal Drug Abuse and Neonatal Drug Withdrawal, Even Mild NAFLD Associated With Higher Mortality. Of alcohol-related deaths, 28%  were due to injuries (eg, from traffic accidents, self-harm, and violence), 21% inivolved digestive disorders, and 19% involved cardiovascular diseases. [Medline]. 360(21):2216-23. Alcohol. Patients with acidaemia or signs of end-organ dysfunction (renal failure, visual loss) require admission to ICU. The American Journal of the Medical Sciences, https://doi.org/10.1097/MAJ.0b013e3181c94601. [Medline]. Review of: Patil N, Becker MWL, Ganetsky M (2010). September 27, 2018; Accessed: October 2,2018. Emergency department nurses may be the first persons to collect the essential data, and it is incumbent upon them to plan and initiate appropriate care. "Mayo," "Mayo Clinic," "MayoClinic.org," "Mayo Clinic Healthy Living," and the triple-shield Mayo Clinic logo are trademarks of Mayo Foundation for Medical Education and Research. 41 Pathophysiology Isopropanol is metabolized to acetone by liver, but unlike methanol and EG, the toxic effects are mediated by isopropanol rather than its metabolite. 1993 Dec. 22(12):1916-8. Methanol is commonly found in windshield-wiper fluid and de-icing products, and may also be found in gas-line antifreeze, paint removers, shoe dyes and embalming fluid. Interestingly the LD50 values for methanol (5.8 g/kg), ethanol (7.1 g/kg) and isopropanol ((5.8 g/ kg) (i.e the amount that will kill half of the test animals) are very similar. Clipboard, Search History, and several other advanced features are temporarily unavailable. Antidotal therapy with fomepizole or ethanol will inhibit ADH and prevent the formation of toxic metabolites in methanol and ethylene glycol poisoning. [Full Text]. Most methanol and ethylene glycol ingestions occur in adults older than 19 years. The metabolites of ethylene glycol are responsible for the toxic effects, which include neurological, cardiopulmonary and renal toxicity. Alcohol toxicity and withdrawal. Although any alcohol can be toxic if ingested in large enough quantities, the term toxic alcohol has traditionally referred to isopropanol, methanol, and ethylene glycol. http://youth.gov/youth-topics/substance-abuse/risk-and-protective-factors-substance-use-abuse-and-dependence. 43 (5):327-45. [Medline]. 53(4):439-450.e10. A small portion is excreted unchanged by the lungs. Clin Toxicol (Phila). The other alcohols. Peces R, Fernández R, Peces C, González E, Olivas E, Renjel F, Jiménez M, Costero O, Montero A, Selgas R. Emerg Med Clin North Am. and a step-by-step approach to calculating the osmolar gap, anion gap and estimating toxic alcohol concentrations. Haemodialysis may not be needed if fomepizole is started early in ethylene glycol poisoning and there is no evidence of acidaemia or renal dysfunction. For those patients who were intoxicated with ethylene glycol, 196 patients were classified as having "major" disability, with an additional 17 patients dying. Patients can be toxicologically cleared if they have a methanol or ethylene glycol concentration < 20mg/dL with no evidence of end-organ dysfunction or haemodynamic instability. The World Health Organization estimates that in 2016, ethanol use resulted in about 3 million deaths (mostly in men), or 5.3% of all deaths around the world—more than tuberculosis, HIV/AIDS, or diabetes. National Institute on Alcohol Abuse and Alcoholism. [Medline]. Later on, the osmolar gap decreases and the anion gap increases as the toxic alcohol is metabolised to form ketones/aldehydes and organic acids. However, in chemistry, "alcohol" refers to a hydroxyl group, consisting of hydrogen bonded to oxygen, attached to a carbon group, according to Georgia State University. Other forms of alcohol — including isopropyl alcohol (found in rubbing alcohol, lotions and some cleaning products) and methanol or ethylene glycol (a common ingredient in antifreeze, paints and solvents) — can cause other types of toxic poisoning that require emergency treatment. Ethyl alcohol (ethanol; CH3 -CH2 -OH) is a low molecular weight hydrocarbon that is derived from the fermentation of sugars and cereals. This conversion involves three discrete enzymes: the microsomal cytochrome P450 isoenzyme CYP2E1, the cytosol-based enzyme alcohol dehydrogenase (ADH), and the peroxisome catalase system. Symptoms may include a decreased level of consciousness, poor or no coordination, vomiting, abdominal pain, and a specific smell on the breath. Falsely elevated creatinine can be seen in isopropanol ingestion, as acetone interferes with colorimetric creatinine assays (urea remains unchanged). National Council on Alcoholism and Drug Dependence. Long-term outcomes may include blindness and kidney failure. It is critical that poisoning due to ethanol and/or other related alcohols should be recognized early in order to initiate appropriate treatments and prevent fatalities. J Korean Med Sci. NLM This is followed by detailed sections on diagnosis, treatment and disposition including evidence-based treatment algorithms for toxic alcohol ingestion (these are gold!) Slideshow, 2002 [Full Text]. Acetaldehyde is then converted to acetate, which is converted to acetyl Co A, and ultimately carbon dioxide and water. Most cases of methanol toxicity involve single patients. Current recommendations for treatment of severe toxic alcohol poisonings. Ann Emerg Med. Fomepizole for the treatment of methanol poisoning.  |  Editor: Anthony J. Busti, MD, PharmD, FNLA, FAHA Last Reviewed: August 2015 Fast Five Quiz: How Much Do You Know About Alcoholism? For discussion of the individual agents, see Methanol Toxicity and Ethylene Glycol Toxicity; for discussion of pediatric ethanol ingestion, see Ethanol Toxicity. In clinical practice, poisoning with ethylene glycol, methanol, and isopropyl alcohol is common. 2008 Jan. 3(1):208-25. 52(4):737-9. https://profreg.medscape.com/px/getpracticeprofile.do?method=getProfessionalProfile&urlCache=aHR0cHM6Ly9lbWVkaWNpbmUubWVkc2NhcGUuY29tL2FydGljbGUvODEyNDExLW92ZXJ2aWV3. Methanol and ethylene glycol acute poisonings - predictors of mortality. There were 2324 non-beverage exposures, with 9 major outcomes and 1 death. Gummin DD, Mowry JB, Spyker DA, Brooks DE, Fraser MO, Banner W. 2016 Annual Report of the American Association of Poison Control Centers' National Poison Data System (NPDS): 34th Annual Report. Formic acid is the main toxic metabolite responsible for the retinal, ophthalmic and neural toxicity seen with methanol ingestion. : toxic alcohol case in the emergency department. Accessed June 20, 2016. Clinical manifestations result from abnormalities of neurologic, cardiopulmonary, and renal function.
