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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

This study explores whether measuring electrical impedance (tissue resistance) during ultrasound-guided nerve blocks can help doctors identify different tissues—like skin, fat, muscle, and nerves—more precisely. Researchers will test this in 100 adults receiving axillary, popliteal, or interscalene nerve blocks. The goal is to improve needle placement, boost block success, and reduce complications such as accidental injection into a nerve or blood vessel.

What this could mean

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

What this could lead to
If successful, this could help doctors place nerve block needles more accurately, potentially increasing success rates and lowering risks like nerve damage.
What could go wrong
This is an early observational study with only 100 participants, so results may not apply to all patients or settings. It measures tissue properties, not direct patient outcomes.
