Optimal nutrition is a cornerstone of critical care management, directly influencing patient recovery, immune response, and outcomes. Evidence-based practices emphasize early initiation of enteral nutrition within 24–48 hours of ICU admission to maintain gut integrity and reduce infection risk. Individualized nutritional assessment, guided by indirect calorimetry and protein targets, ensures adequate energy and macronutrient delivery. Parenteral nutrition is reserved for cases where enteral feeding is contraindicated or insufficient. Micronutrient supplementation, glycemic control, and monitoring of refeeding syndrome are essential. Multidisciplinary collaboration among intensivists, dietitians, and nurses enhances nutritional therapy and improves overall ICU survival rates.
