Practical implications of nutritional support during continuous renal replacement therapy

Continuous blood membrane interactions during continuous renal replacement therapy cause bioincompatibility and low grade inflammatory reactions with potentially adverse consequences on protein metabolism and immunocompetence. In designing a nutritional program for patients receiving this treatment, these adverse metabolic effects, especially the loss of nutritional substrates, must be considered. This review provides a practical overview of nutritional support in acute renal failure, including assessment techniques, determination of nutrient needs, and appropriate intervention for patient support.
