Comparing the Effects of High-protein Nutritional Support with Standard Protein Nutritional Support Through the Administration of Whey Protein Supplements on Clinical Outcomes of Critically Ill Patients At Risk for Refeeding Syndrome: a Randomized Comparative Clinical Trial
The goal of this clinical trial is to determine the optimal protein administration strategy for enhancing both nutritional and clinical outcomes, as well as reducing complications and mortality in ICU patients at risk for refeeding syndrome (RS). This study will include critically ill patients at risk for RS who are receiving supportive nutrition. The primary hypothesis is that higher protein intake will lead to a decreased incidence of refeeding syndrome. It is also expected that patients receiving more protein will have better clinical outcomes, lower mortality, and shorter ICU and hospital stays.
