Abstract
OBJECTIVE: Hyperammonaemia contributes to complications in acute liver failure (ALF) and may be treated with continuous renal replacement therapy (CRRT), but current practice is poorly understood. DESIGN: We retrospectively analysed data for baseline characteristics, ammonia concentration, CRRT use, and outcomes in a cohort of Australian and New Zealand patients with ALF. SETTING: All liver transplant ICUs across Australia and New Zealand. PARTICIPANTS: Sixty-two patients with ALF. MAIN OUTCOME MEASURES: Impact of CRRT on hyperammonaemia and patient outcomes. RESULTS: We studied 62 patients with ALF. The median initial (first 24 h) peak ammonia was 132 μmol/L (interquartile range [IQR], 91-1..
