I cannot find the original paper, but a letter in response to it suggests one should sustain a blood ethanol concentration of 20 to 30 mmol/L (100 to 150 mg/dL). A Norfolk couple report that it tasted "horrible", though the husband finished his glass as a demonstration of his manliness. The mechanism of toxicity of ethylene glycol involves metabolism, but unlike previous examples this does not involve metabolic activation to a reactive metabolite. At this stage, there is no acidosis, but the anion gap is widened (unmetabolised ethylene glycol floods the bloodstream). N Engl J Med 1981;304:976-8. Suppression of metabolism – fomepizole and IV ethanol are temporizing measures; Removal of toxin – haemodialysis; Alkalinisation in order to counteract metabolic acidosis (Na bicarbonate) Folic acid and folinic acid may be useful adjuncts (but does not directly improve patient’s clinical state) Ethylene glycol. Half life is short, but longer with any therapy that blocks the metabolism of ethylene glycol to glycoaldehyde… so with ethanol therapy, the ethylene glycol can hang around for up to 24 hours, With therapy, elimination is entirely renal. The first step is catalysed by the enzyme alcohol dehydrogenase and herein lies the key to treatment of poisoning. The alcohols: ethanol, methanol, isopropanol, ethylene glycol. The treatment of poisoning with ethylene glycol reflects the mechanism and biochemical effects. Several deaths are recorded annually in the U.S. alone. Traditionally, gastric lavage or nasogastric aspiration of gastric contents are the most common methods employed in ethylene glycol poisoning. Clay, Keith L., and R. C. Murphy. As a weak acid, formic acid should become more water soluble in an alkaline bloodstream, and in alkaline urine. Ethylene glycol's metabolites are responsible for the anion gap metabolic acidosis. Pure ethylene glycol is said to be sweet-tasting, but nowadays (in order to deter children, one assumes) the majority of it is tainted with foul-tasting impurities.

Then, you might feel slightly ill. As the glycolic acid begins to appear in the bloodstream, metabolic acidosis ensues and hyperventilation follows. Alcohol dehydrogenase, the same first step enzyme responsible for the metabolism of methyl and ethyl alcohols, slowly catalyzes conversion of EG to glycoaldehyde. Crystals, blood and protein may all be detected in the urine (crystalluria, haematuria and proteinuria, respectively), and the urine may have a low specific gravity. In this study, we investigated the metabolism of ethylene glycol in the Pseudomonas putida strains KT2440 and JM37 by employing growth and bioconversion experiments, directed mutagenesis, and proteome analysis. Thus, this acidosis is "bicarbonate-resistant". The toxicity of ethylene glycol results from its metabolism to more toxic metabolites. There is a lot of good, thorough literature on the management of ethylene glycol toxicity. Ingestion of sufficient amounts is fatal if untreated. Here, we analyzed the metabolism of ethylene glycol. This increases its clearance, and keeps it out of the fatty central nervous system, where its effects are the most destructive (specifically, the effects on the tender juicy retina). b Between 12 and 24 h there is tachypnoea, tachycardia, hypertension, pulmonary oedema and congestive cardiac failure. Fig: Metabolism of Ethylene Glycol . Both susbtances are well removed by dialysis, and on top of that one can adjust the bicarbonate concentration of the dialysate to donate extra bicarbonate to the patient's bloodstream, increasing the correction of the acidosis even further. Ipecac-induced The mechanism of metabolic acidosis is more interesting. "On the metabolic acidosis of ethylene glycol intoxication." Otherwise, much of it is metabolized into hideous daughter-compounds, which are also ex… Most intoxications are associated with ingestion of antifreeze, which is typically 95% EG. Supportive therapy, such as IV fluids, is also important. Adolphe Wurtz (1856) "Sur le glycol ou alcool diatomique" (On glycol or diatomic alcohol), Comptes rendus, 43 : 199-204. By Katzung et al. glucose metabolism, Krebs' cycle, protein synthesis, RNA synthesis and DNA replication for example. The authors (who did not identify themselves) suggested a loading dose of 0.6g per kg body weight, or roughly 40g for a 70kg male, to get to 100mg/dL. Intermediate metabolites of ethylene glycol intoxication., ingestion of antifreeze, which is then metabolised to glycolic is.
