Higher versus standard protein by feeding tube to boost muscle protein synthesis in ICU patients

Increased Protein Amount as a Nutritional Strategy to Enhance Muscle Protein Synthesis in ICU Patients

NA · Maastricht University Medical Center · NCT06714240

This will test whether giving ventilated, critically ill adults more protein through a feeding tube (about 1.3 g/kg/day) helps their muscles make more protein over four days than standard protein (about 0.8 g/kg/day).

What this trial studies

This randomized interventional study will assign 26 mechanically ventilated, enterally fed ICU patients to receive either a standard protein enteral formula (target 0.8 g/kg/day) or a higher-protein enteral formula (target 1.3 g/kg/day). Muscle protein synthesis rates will be measured over a four-day intervention period to compare anabolic responses between groups. Eligible participants are adults expected to require at least three days of mechanical ventilation and a minimum seven-day ICU stay, with several medical exclusions to ensure safety. The trial is conducted at a single center and powered for short-term biologic outcomes rather than long-term functional recovery.

Who should consider this trial

Good fit: Ideal candidates are adults (≥18 years) in the ICU who are mechanically ventilated, suitable for enteral nutrition, expected to need at least three more days of ventilation and an ICU stay of at least seven days.

Not a fit: Patients with morbid obesity (BMI ≥40), spinal cord injury, chronic pre-admission corticosteroid use, severe kidney or liver failure, dialysis requirements, major allergies/intolerances to feed components, or bleeding/anticoagulant disorders are excluded and unlikely to benefit from this protocol.

Why it matters

Potential benefit: If successful, the intervention could reduce ICU-related muscle wasting and help patients regain strength and physical function more quickly after critical illness.

How similar studies have performed: Previous trials of higher protein intake in critically ill patients have produced mixed results and anabolic resistance is a known issue, so evidence is currently conflicting and this direct comparison addresses that gap.
