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
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 This study
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 Results may not be published yet.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.

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.

Summary

This study compared two ultrasound-guided pain blocks—caudal block and quadratus lumborum plane block—in 111 adults undergoing lumbar spine surgery. The goal was to see which provides better pain relief and reduces the need for opioid painkillers. Researchers measured how long it took before patients first asked for extra pain medicine and their pain scores over 24 hours.

What this could mean

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

Active substance
ultrasound-guided caudal block and quadratus lumborum plane block (procedures)
What this could lead to
If one block proves better, it could offer more effective pain control after spine surgery, reducing the need for opioids.
What could go wrong
This is a small, completed study comparing two techniques; results may not apply to all patients or surgeries, and both blocks carry rare risks like infection or nerve injury.
