Critical care management in patients with acute liver failure.

Acute liver failure (ALF) is defined as severe hepatic dysfunction (marked transaminases elevation, detoxification disorder (jaundice and coagulopathy with international normal ratio (INR) > 1.5), the presence of hepatic encephalopathy, and exclusion of underlying chronic liver disease, and a secondary cause like sepsis or cardiogenic shock. Reasons for ALF include paracetamol and warfarin toxicity, autoimmune and viral (mainly hepatitis B and E) hepatitis, and herbal and dietary supplements. Even in terms of meticulous and careful review of the patient, around 20-30% of the reasons remains unknown. In order of its rarity, a randomized controlled trial could hardly be done. However, because of improved ICU treatment, the mortality, even in the advanced stage of ALF decreased. However, in 5-10% of the cases an emergency transplantation is required. This justifies the treatment of this patient cohort in institutions that can provide this kind of treatment.
