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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

Doctors in the ICU need to know if a patient needs more fluids, and they often use ultrasound to check a large belly vein called the inferior vena cava. But that view can be hard to get. This study tests whether measuring a vein in the neck, the right internal jugular vein, works just as well and is faster. Researchers will compare the neck vein measurement with the standard one in 82 adults on breathing machines, and also see how both relate to other fluid-monitoring signals.

What this could mean

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

Active substance
Ultrasound measurement of the right internal jugular vein distensibility index
What this could lead to
If the neck vein measurement works as well as the standard one, doctors could assess fluid status faster and more easily in ICU patients, especially when the usual view is hard to get.
What could go wrong
This is a small observational study, so it can only show whether the two measurements agree, not prove one is better for patient outcomes. The neck vein measurement might not match the standard closely enough in all patients.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

The study population consists of adult patients aged 18 years or older who are admitted to the intensive care unit and receiving invasive mechanical ventilation at the time of assessment. Eligible patients have PVI, PPV, and SVV measurements available and technically adequate right internal jugular vein and inferior vena cava ultrasonographic measurements obtained during the same assessment session. Patients with cardiac arrhythmia or unavailable or incomplete hemodynamic or ultrasonographic measurements are excluded.
