Akutes Leberversagen

Acute liver failure is a rare dynamic disease with a high spontaneous mortality. It is defined as acute (<26 weeks) severe liver insufficiency (INR?>1.5) with hepatic encephalopathy in the absence of chronic liver disease. The most important prognostic parameters in acute liver failure are the etiology as well as the stage of hepatic encephalopathy. Multiorgan failure, infections as well as advanced cerebral edema are the most frequent causes of death in patients with acute liver failure. Management of acute liver failure always requires intensive care surveillance with close monitoring. In case of complications an early and aggressive therapy is recommended. This includes a fluid and blood glucose monitoring, tracheal intubation and mannitol in cases of cerebral edema, a substitution of coagulation factors only in case of hemorrhage, early antibiotics for infections, early renal replacement therapy, N-acetyl cysteine for stage I/II hepatic encephalopathy as well as etiology-specific therapeutic measures. Liver transplantation is the last step therapy.
