About this study
Official title: Enteral Nutrition Delivery in Prone Position Ventilated Patients With Moderate to Severe Acute Respiratory Distress Syndrome: a Randomized Controlled Trial
This pilot study is aimed to compare and assess the impact, safety, and practical utility of gastric versus postpyloric feeding in moderate to severe ARDS patients with prone position ventilation. Patients included will be randomly assigned to receive enteral nutrition either through a nasogastric tube or a nasojejunal tube. The primary endpoint is the achievement of enteral nutrition goals. Secondary endpoints include the incidence of hospital-acquired infections, the number of ventilator-free days within 28 days, ICU length of stay, ICU mortality, 28-day mortality, 60-day mortality rates, the incidence of enteral nutrition intolerance, and the rate of enteral nutrition intake.
- Conditions
- ARDS
- Being tested
- enteral nutrition through nasojejunal tube, enteral nutrition through nasogastric tube

Measured: follow-up till 7-day
Secondary outcomes (8)
Incidence of new Infections
New infections occur after admission to ICU within 28 days after admission to this study
Measured: follow-up till 28-day
Ventilator-free days within 28 days
the number of days within a 28-day period that a patient does not require mechanical ventilation.
Measured: follow-up till 28-day
ICU Length of Stay
Duration of time a patient spends in the ICU from admission to discharge.
Measured: up to 24 weeks
ICU Mortality Rate
The proportion of patients who die in the Intensive Care Unit (ICU) of a hospital
Measured: up to 24 weeks
28-Day Mortality Rate
The proportion of patients who die within 28 days.
Measured: 28 days
60-Day Mortality Rate
The proportion of patients who die within 60 days.
Measured: 60 days
Incidence Rate of Enteral Nutrition Intolerance
The frequency at which patients experience intolerance to enteral feeding.
Measured: 28 days
Daily Enteral Nutrition Intake Rate
It is calculated as the total volume of enteral nutrition fed to a patient each day, divided by the total prescribed enteral nutrition for that day, multiplied by 100%.
Measured: 7 days

Patients included will be randomly assigned to receive enteral nutrition either through a nasogastric tube or a nasojejunal tube. The primary endpoint is the achievement of enteral nutrition goals. Secondary endpoints include the incidence of hospital-acquired infections, the number of ventilator-free days within 28 days, ICU length of stay, ICU mortality, 28-day mortality, 60-day mortality rates, the incidence of enteral nutrition intolerance, and the rate of enteral nutrition intake.

Questions about this trial
What is this clinical trial studying?
A study testing enteral nutrition through nasojejunal tube and enteral nutrition through nasogastric tube in people with ARDS, run by Southeast University, China at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 23 Jan 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

How can a doctor refer a patient or contact the research team?
Contact Airan Liu, PHD (+8615295557466, airanliu@126.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Cumulative Enteral Nutrition intake to target ratio (time frame: follow-up till 7-day). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Jan 2026; AzTrials last refreshed its copy on 7 Nov 2026.
