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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 early study tests a new device that monitors injection pressure in real time during nerve blocks for arm surgeries. 34 adults will be randomly assigned to receive the block with or without the smart needle. The goal is to see if the device helps keep pressure low, which may reduce nerve injury risk.

What this could mean

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

Active substance
Smart Needle Monitoring System (device)
What this could lead to
If it works, this could make nerve blocks safer by helping doctors avoid high injection pressures that may cause nerve damage.
What could go wrong
This is a very early, small feasibility study with only 34 participants, so results may not apply widely. The device may not reduce pressure peaks or improve outcomes significantly.

Study facts

What this study's own registry entry says, in plain language.

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 34 people

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