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 Results may not be published yet.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

Summary

This study compares two ways of giving a nerve block (erector spinae plane block) to control pain after lumbar fusion surgery. Sixty adults undergoing back surgery will be randomly assigned to receive either a single-level or a two-level injection. Researchers will measure pain scores, opioid use, and side effects in the first 24 hours after surgery to see which method works better.

What this could mean

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

Active substance
Erector spinae plane block (nerve block injection)
What this could lead to
If it works, this could show that a two-level nerve block provides better pain relief after lumbar fusion surgery than a single-level block.
What could go wrong
This is a small, early-stage trial with only 60 patients. It may not find a clear difference between the two techniques, and results may not apply to all spine surgeries.
