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 This study
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 Results may not be published yet.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.

Summary

This study tests whether a simple bedside maneuver—raising the legs—combined with ultrasound of the carotid artery can predict if a patient will experience a sudden drop in blood pressure after anesthesia is given. It involves adults undergoing elective surgery for gastrointestinal tumors. The goal is to find a reliable, non-invasive warning sign that could help doctors prevent complications during anesthesia.

What this could mean

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

Active substance
Passive leg raising maneuver and carotid artery Doppler ultrasound
What this could lead to
If successful, this could give anesthesiologists a simple, non-invasive way to predict and prevent dangerous blood pressure drops during surgery, improving patient safety.
What could go wrong
This is a small, early-stage study. The predictive accuracy may be limited, and results may not apply to all surgical patients or settings.
