Positive propylene glycol result in a patient with ethylene glycol poisoning.

چکیده
A 61-year-old man presented with an increased anion-gap metabolic acidosis, an increased serum osmolal gap, and a negative result in an alcohol screen. Gas chromatography revealed an increased ethylene glycol (EG) concentration (22 mg/dL) and a propylene glycol (PG) result that was below the lower limit of quantification ( 5 mg/dL) (Fig. 1A). The patient was treated with hemodialysis, followed by phenytoin and a high-dose lorazepam infusion for a witnessed seizure. By 13 h, the EG concentration had fallen below the lower limit of quantification ( 5 mg/dL); however, a peak identified as PG was observed, corresponding to a concentration of 27 mg/dL (Fig. 1B).

A rapid analysis of plasma/serum ethylene and propylene glycol by headspace gas chromatography
A rapid headspace-gas chromatography (HS-GC) method was developed for the analysis of ethylene glycol and propylene glycol in plasma and serum specimens using 1,3-propanediol as the internal standard. The method employed a single-step derivitization using phenylboronic acid, was linear to 200 mg/dL and had a lower limit of quantitation of 1 mg/dL suitable for clinical analyses. The analytical m...

alcohol poisoning can result in metabolic acidosis, renal failure, blindness, central nervous system (CNS) injury, pulmonary edema, or death. Ethylene glycol is present in antifreeze solutions, deicing solutions, foam stabilizers, and chemical solvents. Methanol is a component of windshield-washing solutions, gas-line antifreeze solutions, solvents, and brake cleaners. Isopropanol is found in r...
متن کاملAcidosis and coma after hemodialysis.
Ethylene glycol poisoning is a rare yet potentially fatal illness seen most commonly in association with ingestion by alcoholics or in suicide attempts. It is characterized by an elevated anion gap metabolic acidosis, osmolal gap, calcium oxalate crystals in the urine, and a well-defined clinical picture. Prompt treatment is crucial because effective intervention can prevent the neurologic, car...
متن کاملEthylene glycol poisoning: a rare but life-threatening cause of metabolic acidosis—a single-centre experience
BACKGROUND Intoxication with ethylene glycol happen all around the world and without rapid recognition and early treatment, mortality from this is high. METHODS In our study, we retrospectively analysed six cases of ethylene glycol intoxication in our department. We measured ethylene glycol or glycolate levels, lactate levels and calculated the osmolal and anion gap. RESULTS Data from six p...
