[Liver function disorders and damage in critically ill intensive care patients]

The course of the disease of critically ill patients is complicated and prognosis worsened by failure of one or more organs. During intensive care monitoring and treatment of vital functions most attention usually is paid to the cardio-pulmonary and renal system; liver function is neglected rather often. In a retrospective study 100 critically ill patients were evaluated, who had serum bilirubin levels above 3,0 mg/dl, but no primary liver disease. Excluded were patients who had liver destruction caused for instance by liver abscess or metastases, and patients with acute hemolysis and extrahepatic cholestasis. Severe infection was the primary cause of disease in 64% of these critically ill patients without primary liver dysfunction; 52% patients had septicemia, 37% patients were in a post-operative or post-traumatic status, 28% patients had severe gastrointestinal complications, 23% had myocardial pump failure, 32% had protracted shock, 29% had hematological disease, 59% had lung failure, and 58% renal failure. It was tried to find a correlation between the different liver function parameters in this group of patients. In spite of rather pronounced pathological findings a statistically significant correlation could only be found between SGPT and SLDH. This study demonstrates the importance of liver involvement in critically ill patients on the one side and the necessity of comprehensive and repeatedly performed investigations of liver function in such patients on the other side.
