| Summary: | Liver failure, both acute and chronic, represents a complex, life-threatening condition frequently requiring intensive care unit (ICU) admission. Nutritional management is a crucial component of supportive therapy, aiming to mitigate catabolism, preserve lean body mass, and support immune and organ function. In acute liver failure (ALF), early nutritional intervention within 24–48 h and individualized energy–protein prescriptions are essential, even in the presence of hepatic encephalopathy. Chronic liver failure (CLF) and acute-on-chronic liver failure (ACLF) are often associated with severe malnutrition, sarcopenia, and systemic inflammation, necessitating tailored nutritional strategies. Subjective Global Assessment (SGA) and Royal Free Hospital Global Assessment (RFH-GA) tools are instrumental in identifying nutritional risk. Enteral nutrition (EN) is preferred across all stages, with parenteral nutrition (PN) reserved for contraindications. Special considerations include micronutrient repletion, prevention of refeeding syndrome, and perioperative nutritional support in transplant candidates and recipients. This clinical overview summarizes current evidence and guidelines on ICU nutrition in liver failure, emphasizing a multidisciplinary approach to improve outcomes. |
