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
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 Results may not be published yet.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 compares two ways to numb the shoulder for surgery: the standard interscalene block and a combination of two other nerve blocks. The goal is to see if the combination provides similar pain relief while better preserving diaphragm function, which is important for breathing. Adults aged 18-65 having arthroscopic shoulder surgery will be randomly assigned to one of the two blocks, and their pain and breathing will be measured 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
Two nerve block procedures: an interscalene block or a combination of anterior suprascapular and axillary nerve blocks, both using bupivacaine.
What this could lead to
If the combined nerve block works as well as the standard one, it could offer a safer way to manage shoulder surgery pain with less impact on breathing.
What could go wrong
This is a small, early-stage trial, so results may not apply to everyone. The combined block might not provide pain relief as effective as the standard approach.
