What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tested whether a miniaturized ultrasound probe placed in the esophagus could help predict outcomes in 50 patients with acute respiratory distress syndrome (ARDS). The probe measures a blood vessel collapse index that may indicate heart strain. Researchers tracked how many days patients needed a breathing machine and survival rates.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this could help doctors better predict how ARDS patients will recover, potentially guiding treatment decisions.
What could go wrong
This is a small, completed observational study with only 50 participants. The findings may not apply to all ARDS patients and need confirmation in larger trials.

This is an AI summary of the original study and may miss details. Read our disclaimer.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Patients hospitalized in Resuscitation, Emergency or Intensive Care Units at the Roger Salengro Hospital at Lille University Hospital. * With acute respiratory distress syndrome of intermediate or severe severity (1) for less than 24 hours. * Mechanical ventilation with tracheal intubation or tracheostomy, in controlled assisted ventilation (VAC) mode. * Patient adapted to mechanical ventilation (no triggering of spontaneous ventilation cycle in VAC mode verified by the equality between the respiratory rate prescribed on the ventilator and the actual respiratory rate of the patient). Exclusion Criteria: * Patient under extracorporeal respiratory assistance at the time of inclusion. * Anomalies or pathologies that make it dangerous or impossible to introduce an ETO probe: * Fistula, perforation, stenosis, varicose vein or diverticulum of the esophagus and / or stomach * History of esophageal and / or gastric surgery * Caustic lesions of the esophagus and / stomach * Tumor or history of oropharyngeal surgery * Unstable lesions of the cervical spine * Coagulopathy (thrombocytopenia \<50 109 / L and / or TP \<50%). * Impossibility of measuring the diameter of the superior vena cava and cVCS in ETO due to poor echogenicity. * Pregnant woman. * Therapeutic limitation measures limiting the treatment of organ failure.
