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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

Hand, wrist, and forearm surgeries often cause significant pain, and an axillary nerve block is a standard way to numb the arm. In the classic approach, doctors target the nerves around the axillary artery under ultrasound. A newer interfascial approach deposits anesthetic between the arm muscles instead, aiming for more even spread with fewer needle movements. This randomized study compares the two methods in 110 adults to see which one reliably blocks pain well enough to complete surgery without extra numbing or general anesthesia.

What this could mean

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

Active substance
Two ultrasound-guided axillary brachial plexus nerve block techniques: the classic perivascular approach and a modified interfascial approach
What this could lead to
If the interfascial approach works better, it could give anesthesiologists a more reliable way to numb the arm for hand, wrist, and forearm surgery, with fewer needle passes and less need for extra painkillers or general anesthesia.
What could go wrong
This is a single-center study of 110 people, so its results may not hold in other hospitals or with different surgeons. Nerve blocks can fail partially, cause temporary numbness or weakness, or rarely lead to nerve injury or local anesthetic complications.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 110 people

The number the study aims to enrol. It can still change while the study runs.
