Gut Oxygen Therapy for Ischemic-Hypoxic Bowel Disease
Recruiting now · Not applicable · Has a placebo group
Conditions studied: Chronic Ischemic-Hypoxic Enteropathy
In brief
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.

You may qualify if…
- Definite diagnosis of chronic heart failure or obstructive sleep apnea (OSA) with chronic hypoxia;
- Comorbid intestinal dysmotility (abdominal distension, constipation, diarrhea, or abdominal pain);
