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 Results may not be published yet.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.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tests whether a stellate ganglion block (a nerve block injection) can improve neurological outcomes in people who have had a bleeding stroke from a ruptured aneurysm. The procedure is done before surgery to reduce brain artery spasms and improve blood flow. Researchers will follow 560 patients for 90 days to see if it leads to better function and fewer complications.

What this could mean

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

Active substance
stellate ganglion block (nerve block with ropivacaine)
What this could lead to
If it works, this could point toward a simple procedure to improve recovery and reduce complications after a bleeding stroke.
What could go wrong
This is an early-stage trial with no phase, so results are uncertain. The procedure carries risks like infection or nerve damage, and the benefit for long-term recovery is not yet proven.
