What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 will check if a simple ultrasound of the neck vein, done before and right after anesthesia, can predict low blood pressure during surgery and kidney injury afterward. Researchers will observe 150 adults having major abdominal surgery. The goal is to see if changes in the vein's shape can warn doctors ahead of time.

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 give doctors a simple bedside test to predict and prevent dangerous low blood pressure during surgery.
What could go wrong
This is an observational study, not a treatment trial. It may not find a clear link, and results may not apply to all types of surgery or 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 adults aged 18 years and older undergoing major abdominal or visceral surgery under general anesthesia with propofol induction at the Department of Anestesiology and Intensive Care Department in the Emergency County Hospital in Târgu Mureș. Patients will be enrolled prospectively in the preoperative period if they meet eligibility criteria, have routine perioperative blood pressure monitoring, and are able to undergo internal jugular vein ultrasound before and immediately after induction. The cohort will be followed through postoperative days 1 to 3 for creatinine-based assessment of acute kidney injury.
