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 Results may not be published yet.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

Summary

This study looks at whether ultrasound measurements taken before placing a central line in the neck can predict when the procedure will be difficult. Researchers will track 150 intensive care patients, recording details like vein size, depth, and position, along with the doctor's experience. The goal is to create a risk score that helps doctors anticipate challenges and improve the chances of success on the first try.

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 lead to a simple ultrasound-based scoring tool that helps doctors predict and avoid difficult IV insertions, reducing complications in intensive care patients.
What could go wrong
This is an observational study, so it cannot prove cause and effect. The risk score may not be accurate enough for all patients or settings, and the study is relatively small.

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