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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 a specific ultrasound-guided nerve block can reduce pain after elective lower back surgery better than the usual method of injecting pain medicine into the wound. Adults aged 18-65 undergoing surgery for conditions like a herniated disc or spinal stenosis will receive either the combined nerve block or standard wound infiltration before the procedure. Researchers will measure pain levels, opioid use, and recovery speed over the first two days after surgery.

What this could mean

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

Active substance
bupivacaine
What this could lead to
If effective, this combined nerve block could offer better pain control after spine surgery, reducing opioid use and speeding recovery.
What could go wrong
This is a small, single-center trial (50 people). The nerve block may not provide significantly better pain relief than the standard approach, and there is a small risk of side effects like bleeding or infection.
