Nutritional Support for Septic Patients with CKD Stage V

Introduction to Nutritional Support

The American Society for Parenteral and Enteral Nutrition recommends enteral nutrition (EN) as the first-line route for septic patients with CKD Stage V, if the gastrointestinal tract is functional, to reduce ICU-acquired infections and shorten ICU/hospital stays 3
The European Society for Clinical Nutrition and Metabolism suggests that EN should be started at low rates and increased slowly over days, with strict monitoring of plasma electrolytes and phosphorus to prevent refeeding syndrome 2, 4

The American College of Physicians recommends that TPN is indicated when the gastrointestinal tract is non-functional, inaccessible, or when EN fails to meet nutritional requirements despite optimization 1, 2
The Society of Critical Care Medicine suggests that supplemental parenteral nutrition may be necessary when EN alone cannot achieve protein and energy targets, which is common in critically ill patients 5, 2

The National Kidney Foundation recommends providing at least 1.2-1.3 g/kg/day of protein in septic CKD Stage V patients, regardless of dialysis status, to promote protein synthesis and conserve tissue 5, 6
The American Heart Association suggests providing 30-35 kcal/kg/day for patients ≥60 years old, and 35 kcal/kg/day for those <60 years old, to improve serum protein markers and reduce morbidity 6

The European Renal Association recommends using concentrated "renal" TPN formulas with higher protein content and lower electrolyte content to achieve protein targets while minimizing fluid overload 5, 1
The American Society for Parenteral and Enteral Nutrition suggests that the choice of formula should prioritize the calorie-to-protein ratio to provide accurate dosing in clinical practice 1

The International Society of Renal Nutrition and Metabolism recommends calculating protein catabolic rate in patients on KRT when feasible, and repeating indirect calorimetry measurements when clinical condition changes to adjust energy targets appropriately 5, 1, 4
The Society of Critical Care Medicine suggests reassessing nutritional route daily, and transitioning from TPN to EN as soon as gastrointestinal function permits 2, 3
