What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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 Results may not be published yet.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
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This status has not been confirmed recently, so it may be out of date.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

Researchers compare two ultrasound-guided nerve block combinations to numb the arm during surgery for a dialysis fistula. Adults with end-stage kidney disease receive either an intercostobrachial nerve block or an erector spinae block, each added to a standard supraclavicular block. The goal is to see which combination achieves complete sensory block and better controls pain.

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 (intercostobrachial or erector spinae, each with supraclavicular block)
What this could lead to
If one approach proves better, it could become the preferred way to keep patients comfortable during fistula surgery and reduce the need for extra pain medicine.
What could go wrong
Nerve blocks can fail to numb the whole arm or cause temporary breathing problems, and this single-center study may not apply to all patients or hospitals.
