Acute liver failure following paracetamol overdose

Area of Science:

• Hepatology
• Toxicology
• Critical Care Medicine

Background:

• Acute liver failure (ALF) is a rare but life-threatening syndrome characterized by coagulopathy, jaundice, and encephalopathy in individuals without pre-existing liver disease.
• Paracetamol (acetaminophen) overdose is the predominant cause of ALF in the United Kingdom, frequently leading to extrahepatic organ dysfunction necessitating intensive care.

Observation:

• This report details a case of hyper acute liver failure directly resulting from a paracetamol overdose.
• The patient presented with severe symptoms requiring immediate and comprehensive medical intervention.

Findings:

• Management strategies included prompt diagnosis, administration of N-acetyl cysteine, fluid resuscitation, and broad-spectrum antibiotics.
• Early intubation and transfer to a transplant center were crucial due to the development of hepatic encephalopathy.
• Neuroprotective measures, hypertonic saline for intracranial hypertension, and high-dose hemofiltration to reduce ammonia levels were implemented.

Implications:

• Aggressive critical care management and specialized input are associated with favorable outcomes in patients with paracetamol-induced hyper acute liver failure.
• Liver transplantation remains a vital option for patients who do not respond to medical treatment alone.
