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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 tests whether using standard oxygen equipment, guided by the patient's own oxygen and circulation levels, can keep blood pressure and brain oxygen more stable during anesthesia for major spinal surgery. Researchers will monitor 90 adults to see if this physiology-guided approach reduces dangerous drops in blood pressure and brain oxygen. The goal is to find a simpler, safer method without needing advanced breathing devices.

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 safer, simpler way to prepare patients for anesthesia during major spinal surgery, reducing risks like drops in blood pressure or brain oxygen levels.
What could go wrong
This is a small, early-stage study (90 participants) focused on monitoring, not a new drug or device. Results may not apply to all surgeries or patients, and the approach may not show clear benefits.
