Abstract

CASE REPORTS:

Two patients severely intoxicated with ethylene glycol became anuric and were treated by hemodialysis and the antidote, 4-methylpyrazole. On admission, their plasma ethylene glycol concentrations were 0.42 and 3 g/L respectively and no alcohol was detected. The elimination of 4-methylpyrazole in the dialysate represented 45% of the total body elimination. Clearances of 4-methylpyrazole by hemodialysis were 80 mL/min and 52 mL/min respectively.

RESULTS:

In such cases, the authors propose infusion of a 4-methylpyrazole loading dose of 10-20 mg/kg before dialysis and intravenous infusion of 1-1.5 mg/kg/h during the 8-12 hours of hemodialysis to compensate the loss in dialysate.
