Arterial ammonia and clinical risk factors for encephalopathy and intracranial hypertension in acute liver failure
William Bernal, Catherine Hall, Constantine J. Karvellas, Georg Auzinger, Elizabeth Sizer, Julia Wendon – 28 November 2007 – High circulating ammonia concentrations are common in patients with acute liver failure (ALF) and are associated with hepatic encephalopathy (HE) and intracranial hypertension (ICH). Other risk factors are poorly characterized. We evaluated the relation of the admission arterial ammonia concentration and other clinical variables with the development of HE and ICH.
