What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study

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
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 Results may not be published yet.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

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.

Summary

This study looks at whether a simple neck ultrasound measurement can predict a dangerous drop in blood pressure after anesthesia is given. Researchers will measure the collapsibility of the internal jugular vein in 70 patients aged 60 or older who are scheduled for laparoscopic colorectal surgery. The goal is to find a cut-off value that identifies those at risk, so anesthesiologists can take preventive steps.

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 the neck ultrasound measurement proves reliable, it could give anesthesiologists a simple, non-invasive tool to predict and prevent low blood pressure during surgery in older patients.
What could go wrong
This is a small observational study, not a treatment trial. The measurement may not be accurate enough to replace current methods, and results may not apply to other surgeries or younger patients.
