Brief summary

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.

Detailed description

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.

Interventions

BIOLOGICALFecal microbiota transplantation (FMT) by nasal jejunal tube

FMT was administered via a naso-jejunal tube to inject 50ml commercial intestinal bacterial suspension into the jejunum.

MeasureTime frameDescription
Changes of intestinal microbiota and its metabolites-48, 72 and 96 hours after first FMT.Rectal swab was taken and analysed by 16S rRNA gene sequencing and metabolomics.
Intestinal barrier function-24, 0, 24, 48, 72 and 96 hours after first FMT.2ml of peripheral venous blood was collected for the measurement of serum lipopolysaccharide (LPS), diamine oxidase (DAO), and D-lactic acid.
Acute Physiology and Chronic Health Evaluation (APACHE) Ⅱ score-48, -24, 0, 24, 48, 72 and 96 hours after first FMT.Acute Physiology and Chronic Health Evaluation (APACHE) Ⅱ score is a scoring system used to assess the severity of critically ill patients. APACHE II score ranges from 0 to 71. The higher the score, the greater the severity and the poorer the prognosis.
