IBCC Episode 74 - Toxic Alcohols

Ethylene glycol and methanol poisoning are explored, emphasizing that toxic alcohols become dangerous when metabolized into formic and glycolic acids. The discussion covers the biphasic toxicity, where initial symptoms of inebriation shift to severe conditions as metabolites form. Treatment strategies include blocking alcohol dehydrogenase to prevent metabolite creation and dialysis to eliminate existing metabolites. The hosts debate the utility of the osmolar gap in diagnosis, suggesting serial anion gap measurements as a more effective screening tool. They also address clinical scenarios, such as differentiating lactate levels and recognizing symptoms like hypocalcemia, offering insights into diagnosis, decontamination, and the use of fomepizole or ethanol for treatment.
