Официальное название

Efficacy and Safety of Gut Oxygen Therapy for Ischemic-Hypoxic Bowel Disease: A Single-center, Double-blind, Randomized, Intra-individual Crossover Controlled Study

Обзор

This single-center, double-blind, randomized, intra-individual crossover controlled study aims to investigate the efficacy and safety of intestinal oxygen therapy via a deep intestinal catheter as a targeted route for intestinal oxygen delivery in the treatment of ischemic-hypoxic enteropathy, and simultaneously to explore and verify the chronobiological differences. Data have been obtained from the study based on the first version of our pilot study. Considering ethics and cost-effectiveness, a new protocol needs to be designed to achieve the research goals with minimal intervention, minimal cost, and the smallest sample size.

Подробное описание

Eligible subjects meeting all inclusion criteria and none of the exclusion criteria will be randomized in a crossover manner within the individual to receive, via a deep intestinal catheter, either 500 mL of oxygen or placebo (sham group), administered at three separate time points over the course of one day. The data of test results before and after treatment were collected to evaluate the efficacy and safety of gut oxygen therapy.

Критерии участия

Критерии включения

  • Comorbid intestinal dysmotility (abdominal distension, constipation, diarrhea, or abdominal pain);
  • Disease duration ≥1 month with poor response to conventional treatment;
  • Tolerability of transendoscopic enteral tubing (TET) with successful placement of the tube at the ileocecal junction;

  • Primary organic gastrointestinal diseases, intestinal obstruction, inflammatory bowel disease, or severe hepatic/renal failure;
  • Hemodynamically unstable, unable to tolerate sequential intervention (time-sequenced intervention);
  • Presence of cough or spinal disorders that prevent maintaining a resting state during bed rest;
  • Failure of arterial catheterization or endoscopic tube placement;
  • Mental or cognitive impairment that precludes cooperation with assessments.
