简要总结

Considering that intestinal microbiota plays a crucial role in intestinal function, fecal microbiota transplantation (FMT) may provide a new therapeutic strategy for the treatment of intestinal nutrition intolerance in critically ill ICU patients. The purpose of this study was to investigate the effects of FMT on the recovery of gastrointestinal dysfunction-induced enteral nutrition intolerance in critically ill patients admitted to ICU, and observe the effects on gastrointestinal barrier function, as well as the effects on length of stay in ICU, ICU mortality, in-hospital mortality, and 28-day mortality.

详细描述

Patients in the intensive care unit (ICU) are often at risk for gastrointestinal dysfunction and malnutrition. Gastrointestinal dysfunction is associated with poorer clinical outcomes, including longer mechanical ventilation, longer ICU stay, and increased 90-day mortality. Due to the influence of primary severe diseases and the use of proton pump inhibitors (PPI) and antibiotics, ICU patients with severe illness may have severe disturbance of intestinal flora, impairment of intestinal barrier function, high incidence of gastrointestinal dysfunction-induced enteral nutrition intolerance, and severe intestinal systemic inflammation and organ function injury. Considering that intestinal microbiota plays a crucial role in intestinal function, fecal microbiota transplantation (FMT) may provide a new therapeutic strategy for the treatment of gastrointestinal dysfunction-induced enteral nutrition intolerance in critically ill ICU patients. The project plans through nasal jejunal tube way to give FMT, to investigate its effect on the recovery of gastrointestinal dysfunction-induced enteral nutrition intolerance in severe patients admitted to ICU, and to observe its effect on gastrointestinal barrier function.

研究组 & 干预措施

Control group

No Intervention

Receive ICU standard treatment.

FMT intervention Group

Experimental

In addition to ICU standard treatment, 50ml commercial intestinal bacterial suspension was administered via a naso-jejunal tube to the jejunum from 11:00 to 13:00 every day for 3 consecutive days.

干预措施: Fecal microbiota transplantation (FMT) by nasal jejunal tube (Biological)
