La description
Inclusion Criteria:
- Definite diagnosis of chronic heart failure or obstructive sleep apnea (OSA) with chronic hypoxia;
- 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;
- Age 18-80 years;
- Able to cooperate with bed rest therapy and provide written informed consent.
Exclusion Criteria:
- Oxygenation index >400 without supplemental oxygen and/or resting oxygen saturation ≥96%;
- 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.

Armes et Interventions
Groupe de participants / Bras |
Intervention / Traitement |
|---|---|
|
Expérimental: Crossover Sequence A - O2 then Sham
Eligible subjects meeting all inclusion criteria and none of the exclusion criteria randomized to this sequence will receive interventions at three separate time points over one day via a deep intestinal catheter
|
Subjects will receive interventions in a crossover manner at three separate time points over one day as follows: Time 1: 500 mL of oxygen (flow rate: 1 L/min) Time 2: 500 mL of no air (no oxygen) Time 3: 500 mL of oxygen (flow rate: 1 L/min) |
|
Expérimental: Crossover Sequence B - Sham then Oxygen (O2)
Eligible subjects meeting all inclusion criteria and none of the exclusion criteria randomized to this sequence will receive reverse interventions at three separate time points over one day via a deep intestinal catheter.

Subjects will receive interventions in a crossover manner at three separate time points over one day as follows: Time 1: 500 mL of no air (no oxygen) Time 2: 500 mL of oxygen (flow rate: 1 L/min) Time 3: 500 mL of oxygen (flow rate: 1 L/min) |
Que mesure l'étude ?
Principaux critères de jugement
Mesure des résultats |
Description de la mesure |
Délai |
|---|---|---|
|
Changes in arterial blood gas
Délai: Perioperative/Periprocedural
|
Arterial blood gas analysis results, including partial pressure of oxygen, oxygen concentration, partial pressure of carbon dioxide, oxygenation index, and concentrations of various ions and electrolytes, were obtained at baseline and at intermittent time points within a 30-minute period
|
Perioperative/Periprocedural
|
Mesures de résultats secondaires
Mesure des résultats |
Description de la mesure |
Délai |
|---|---|---|
|
Changes in electrocardiographic data
Délai: Perioperative/Periprocedural
|
Electrocardiographic data, comprising P-wave morphology, QRS complex duration, QT interval, among other relevant indices, were acquired throughout the periprocedural course.
|
Perioperative/Periprocedural
|
|
Changes in electroencephalographic data
Délai: Perioperative/Periprocedural
|
Electroencephalographic parameters-specifically the wavelengths and amplitudes of alpha, beta, and other relevant frequency bands-were measured throughout the periprocedural course.
|
Perioperative/Periprocedural
|
|
Overall patient satisfaction with intervention.
Délai: Perioperative/Periprocedural
|
The patients' satisfaction with the treatment was graded into five levels: very dissatisfied, dissatisfied, average, relatively satisfied, and very satisfied.
The differences of treatment satisfaction among different groups were compared.
|
Perioperative/Periprocedural
|
|
The incidence rate of adverse events
Délai: Perioperative/Periprocedural
|
The number of adverse reactions reported from the start of treatment to the end of follow-up
|
Perioperative/Periprocedural
|
|
The changes in gut microbiota composition and metabolites before and after treatment.
Délai: Perioperative/Periprocedural
|
The 16s-RNA or meta-analysis of gut microbiota will be used.
