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 Results may not be published yet.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

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 compares two common anesthesia methods—inhaled gases (sevoflurane or desflurane) versus intravenous propofol—in 84 adults having brain tumor surgery. Researchers will measure brain oxygen levels, swelling, and thinking skills after surgery to see which approach better protects the brain. The goal is to guide safer anesthesia choices for future patients.

What this could mean

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

Active substance
Sevoflurane, Desflurane, Propofol
What this could lead to
If successful, this could help doctors choose the best anesthesia for brain tumor surgery to protect brain function and reduce recovery problems.
What could go wrong
This is a small, early-phase study (84 people) looking at short-term effects, not long-term outcomes. Results may not apply to all patients or surgeries.
