Liver dysfunction is frequently observed in critically ill patients. Its occurrence is associated with high morbidity and mortality. The most frequent entities of hepatic dysfunction in the intensive care unit are shock liver and cholestatic liver dysfunction with incidence rates up to 10 and 30 %, respectively.Both conditions are frequently triggered by hypoxic and/or ischemic events, most commonly cardiogenic shock and sepsis/septic shock. However, several other potential contributors have been identified especially for cholestatic liver dysfunction. Apart from chronic liver diseases and malignancies, iatrogenic factors such as total parenteral nutrition, high pressure ventilation, surgical procedures, drugs and blood transfusions promote its occurrence.In shock liver and in cholestatic liver disease, early detection and therapy of the underlying disease is the only established treatment.
