Ethylene Glycol Toxicity

Ethylene glycol (CHO) is a toxic alcohol in various household and industrial agents. "Toxic alcohols" is a collective term that includes methanol, ethylene glycol, and isopropyl alcohol. Ethylene glycol exposure can be extremely dangerous, with significant morbidity and mortality if left untreated. Ethylene glycol is a colorless, sweet-tasting liquid commonly found in antifreeze but occasionally used for other purposes, such as industrial solvents. Exposures are generally observed due to accidental or intentional ingestions, with its sweet taste lending to accidental toxic exposures. In contrast, intentional exposures may be motivated by a suicide attempt or desire for inebriation in the absence of ethanol. Ethylene glycol exposures can cause varying toxicity, and management generally requires supportive care, close laboratory monitoring, and antidote therapy. The primary treatments are either ethanol or fomepizole and, occasionally, dialysis.
