Using fecal microbiota transplantation to improve gut function in ICU patients

Efficacy of Fecal Microbiota Transplantation in Critically Ill ICU Patients With Gastrointestinal Dysfunction: a Single-center, Non-blind, Randomized Controlled Study

Phase2; Phase3 Interventional Wuhan Union Hospital, China · NCT06603883

This study tests whether giving a special treatment using healthy gut bacteria can help critically ill patients in the ICU recover their gut function and possibly shorten their hospital stay.

What this trial studies

This study investigates the effects of fecal microbiota transplantation (FMT) on gastrointestinal dysfunction in critically ill patients admitted to the ICU. It aims to assess how FMT can aid in the recovery of gut function, improve gastrointestinal barrier integrity, and potentially reduce ICU stay and mortality rates. Patients will receive FMT via a nasal jejunal tube, and the study will monitor various clinical outcomes including length of ICU stay and mortality rates over a 28-day period. The research focuses on patients who have been in the ICU for at least 24 hours and exhibit signs of gastrointestinal dysfunction.

Who should consider this trial

Good fit: Ideal candidates are ICU patients aged 8 to 70 years with gastrointestinal dysfunction who are expected to stay in the ICU for at least 7 days.

Not a fit: Patients with severe systemic infections, hemodynamic instability, or those at high risk of death within 5 days may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve recovery times and outcomes for critically ill patients with gastrointestinal dysfunction.

How similar studies have performed: While the use of FMT in critically ill patients is a relatively novel approach, preliminary studies have shown promise in improving gut health and clinical outcomes.
