Intensive Care Management of Patients with Acute Liver Failure with Emphasis on Systemic Hemodynamic Instability and Cerebral Edema: A Critical Appraisal of Pathophysiology

Acute liver failure (ALF) is a devastating disease leading to multiorgan dysfunction. The most dramatic impact of ALF is on the brain, as hepatic encephalopathy and intracranial hypertension (IH) develop. IH is associated with systemic hemodynamic instability, alterations in the regulation of cerebral blood flow and the development of cerebral edema. This review focuses on the pathophysiology of IH with special emphasis on cerebral blood flow and the development of cerebral edema. Based on these considerations, both traditional and new treatments for the management of IH in the future are discussed
