[Liver diseases in the intensive care unit].

Abstract

The frequency of liver diseases in the intensive care unit has increased significantly in recent years and is now observed in up to 20% of critically ill patients. The occurrence of liver disease is associated with significantly increased morbidity and mortality. Two groups of liver diseases in the intensive care unit can be distinguished. First, the group of "primary hepatic dysfunctions", which includes primary acute liver failure as well as acute-on-chronic liver failure in patients with pre-existing liver cirrhosis. The second group of "secondary or acquired liver diseases" includes cholestatic liver diseases, as well as hypoxic liver injury and mixed forms, as well as other rarer liver diseases. Due to the diversity of liver diseases and the very different triggers, sufficient knowledge of the underlying changes (including hemodynamic changes, inflammatory states or drug-related) is essential. Early recognition, diagnosis, and treatment of the underlying disease are essential for all liver dysfunction in critically ill patients in the intensive care unit. This review article aims to take a closer look at liver diseases in the intensive care unit and provides insight into diagnostics and treatment options.
