Hyperosmolality: another indication for hemodialysis following acute ethylene glycol poisoning.

When given early, fomepizole has demonstrated an effective role in the treatment of ethylene glycol (EG) intoxication, often eliminating the need for hemodialysis (HD). Many indications for HD have been suggested for EG intoxication. We present a case of EG intoxication with the second highest reported EG concentration. Despite early treatment with fomepizole and without the development of acidosis or renal insufficiency, the patient required HD for hyperosmolality and subsequent electrolyte imbalances. Indications for HD following EG intoxication are discussed.
