Hepatology - Guidelines on Parenteral Nutrition, Chapter 16

Area of Science:

• Hepatology
• Gastroenterology
• Clinical Nutrition

Background:

• Parenteral nutrition (PN) is a critical intervention for patients with severe liver conditions.
• Alcoholic steatohepatitis (ASH) and cirrhosis often lead to malnutrition, necessitating nutritional support.
• Hepatic encephalopathy (HE) and post-liver transplant scenarios present unique challenges for nutritional management.

Purpose of the Study:

• To outline the indications and timing for initiating parenteral nutrition in patients with ASH and cirrhosis.
• To provide guidance on nutritional support for cirrhotic patients undergoing fasting periods or experiencing HE.
• To define the role of artificial nutrition in acute liver failure and post-liver transplant care.

Main Methods:

• Review of current clinical guidelines and evidence for nutritional support in liver disease.
• Analysis of indications for PN in ASH, cirrhosis, HE, and acute liver failure.
• Consideration of enteral nutrition as a preferred route when feasible.

Main Results:

• PN is indicated for moderate to severe malnutrition in ASH and cirrhosis, with immediate initiation advised if oral/enteral feeding is impossible.
• Basal glucose infusion is recommended for patients fasting >12 hours, with total PN required for fasts >72 hours.
• Early postoperative PN is recommended for cirrhotic patients post-transplant if oral/enteral intake is inadequate; artificial nutrition is considered in acute liver failure within 5-7 days if oral intake is not resumed.

Conclusions:

• Parenteral nutrition is essential for specific patient groups with advanced liver disease, malnutrition, or acute liver failure.
• Enteral nutrition, particularly via nasoduodenal tube, should be prioritized whenever feasible.
• Timely and appropriate nutritional intervention is key to managing complications and improving outcomes in liver disease patients.
