Summary
Nutritional support for critically ill patients with acute renal failure has evolved with early dialysis. Standard diets are now suitable, but nutrient needs during dialysis require further study.
Area of Science:
- Critical care medicine
- Nephrology
- Clinical nutrition
Context:
- Critically ill patients with acute renal failure (ARF) often require nutritional support.
- The advent of early extrarenal depuration (ERD) techniques has shifted traditional nutritional management strategies for ARF.
- Previous recommendations for ARF nutritional support are being re-evaluated in light of ERD.
Purpose:
- To review and update recommendations for nutritional and metabolic support in critically ill patients with ARF, considering the impact of ERD.
- To clarify the role of specific macronutrient intakes (protein, glucose, lipids) in patients undergoing ERD.
- To highlight areas requiring further research regarding nutrient management and the use of ERD for nutritional support.
Summary:
- Nutritional support for critically ill patients with ARF has changed due to increased use of ERD techniques.
- Standard diets are generally appropriate for patients on ERD, with specific guidelines for protein, glucose, and lipid administration.
- Essential amino acid-only formulations are no longer recommended; protein intake should match the clinical situation.
Impact:
- Provides updated guidance on nutritional support for critically ill patients with ARF undergoing ERD.
- Suggests that standard diets are feasible, challenging previous restrictive approaches.
- Identifies knowledge gaps concerning nutrient loss during ERD and its potential role in nutritional therapy, necessitating further investigation.
