Efficiency of acidemia correction on intermittent versus continuous hemodialysis in acute methanol poisoning

Abstract

CONTEXT: Acidemia is a marker of prognosis in methanol poisoning, as well as compounding formate-induced cytotoxicity. Prompt correction of acidemia is a key treatment of methanol toxicity and methods to optimize this are poorly defined. OBJECTIVE: We studied the efficiency of acidemia correction by intermittent hemodialysis (IHD) and continuous renal replacement therapy (CRRT) in a mass outbreak of methanol poisoning. METHODS: were determined in IHD- and CRRT-treated patients. RESULTS: was 5.67 ± 0.90 mmol/L/h for IHD versus 2.17 ± 0.74 mmol/L/h for CRRT (p < 0.001). CONCLUSIONS: Our study supports the superiority of IHD over CRRT in terms of the rate of acidemia correction.
