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 Results may not be published yet.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

Summary

This study compares two ultrasound-guided nerve blocks—serratus intercostal plane block and erector spinae plane block—for pain control after open kidney removal. 132 adults scheduled for elective open nephrectomy will be randomly assigned to receive one of the two blocks. The goal is to see which block provides better pain relief and reduces the need for opioids, helping patients recover faster with fewer side effects.

What this could mean

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

Active substance
bupivacaine (a local anesthetic)
What this could lead to
If one block works better, it could offer a safer, more effective way to manage pain after kidney surgery, reducing opioid use and speeding recovery.
What could go wrong
This is a small, early-stage comparison study, not a large confirmatory trial. Results may not apply to all patients or surgeries, and individual responses to nerve blocks vary.

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 132 people

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