Comparing high-protein and standard protein nutrition for critically ill patients at risk for refeeding syndrome

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

Not applicable Interventional Shahid Beheshti University · NCT06825377

This study is testing whether giving critically ill patients more protein in their nutrition can help them recover better and avoid serious complications while in the ICU.

What this trial studies

This clinical trial aims to identify the best protein administration strategy to improve nutritional and clinical outcomes while reducing complications and mortality in ICU patients at risk for refeeding syndrome. Participants will be randomly assigned to receive either high-protein or standard-protein nutritional support upon ICU admission. The study will monitor various health metrics, including multi-organ dysfunction syndrome and protein intake levels, over a 14-day intervention period. The primary hypothesis is that higher protein intake will lead to fewer cases of refeeding syndrome and better overall health outcomes.

Who should consider this trial

Good fit: Ideal candidates are critically ill patients aged 18 to 65 who are at risk for refeeding syndrome and can tolerate enteral nutrition.

Not a fit: Patients with active infections, severe organ failure, or those with specific conditions requiring different protein needs may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved nutritional strategies that enhance recovery and reduce mortality in critically ill patients.

How similar studies have performed: While the approach of varying protein intake in critically ill patients is established, this specific comparison of high-protein versus standard protein nutritional support is novel.
