What the trial is, and whether it could suit you
Study Objective This clinical trial primarily aims to investigate whether semi-elemental enteral nutrition (SEN) improves gastrointestinal tolerance in patients with severe traumatic brain injury (TBI) and to evaluate its impact on clinical outcomes. The safety profile of SEN will also be assessed.
Key Research Questions Does SEN reduce the incidence of acute gastrointestinal injury (AGI) in severe TBI patients?
Study Design
Participants will be randomized 1:1 into either:
Intervention group: Receives SEN initiated within 48 hours post-injury and continued for ≥7 days.
Control group: Receives standard enteral nutrition over the same period.
