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 Results may not be published yet.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

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 trial tests two ultrasound-guided pain blocks in 56 children having laparoscopic abdominal surgery. Each child receives either a transversus abdominis plane (TAP) block or a linea semilunaris block before surgery starts. Researchers measure total opioid use in the first 24 hours after surgery, along with pain scores and side effects. The goal is to find which block provides better pain relief and reduces the need for opioids.

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 nerve blocks using bupivacaine, either a transversus abdominis plane (TAP) block or a linea semilunaris block
What this could lead to
If one block works better, it could give children safer, more effective pain relief after abdominal surgery and reduce their need for opioids.
What could go wrong
This is a small, early trial with 56 children, so results may not apply to all patients. Both blocks carry small risks like bleeding, infection, or the block not working fully.
