What you need to know about: acute liver failure.

ABSTRACT

Acute liver failure is a rare but important clinical syndrome, with a high mortality rate. Prompt recognition, appropriate management and early referral to a liver transplant centre can lead to good outcomes in these critically unwell patients. This article gives an overview of the key clinical challenges and optimal management of patients with acute liver failure. Acute liver failure is defined and a comprehensive list of aetiologies and suggested investigations is provided. The clinical challenges of sepsis, renal impairment, coagulopathy, hypoglycaemia, haemodynamic instability and cerebral oedema are discussed. Quadruple H therapy, a combination of therapies aimed to reduce cerebral oedema in acute liver failure, is described. A systemic guide to managing patients with acute liver failure is provided, as are indications for referral to a liver transplant centre.
