Take Home Points
Toxic alcohols generally refer to methanol and ethylene glycol as these substances pose significant metabolic derangement and end-organ damage.- Patient who present shortly after ingestion will simply look inebriated – no different than ethanol intoxication. At this point, patients will have an elevated osmolar gap and little to no anion gap.
- Patient who presents in a delayed fashion after ingestion may have a normal osmolar gap however will manifest the signs of end-organ damage: anion gap metabolic acidosis, visual impairment, or renal dysfunction.
- The osmolar gap is poorly sensitive, specific surrogate measure that is used to detect the presence of toxic alcohols. A normal osm gap does not rule out a toxic alcohol ingestion.
- Management includes fomepizole, hemodialysis, and vitamin supplementation.
