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 Results may not be published yet.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 tests whether a nerve block (rectus sheath block) can control pain after open abdominal aortic aneurysm repair as well as the standard epidural analgesia, but with fewer complications. About 60 adults undergoing elective surgery will be randomly assigned to one of the two pain management methods. Researchers will measure pain levels and track any side effects or need for extra pain medication.

What this could mean

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

Active substance
rectus sheath block (nerve block)
What this could lead to
If the nerve block works as well as epidural analgesia with fewer side effects, it could offer a simpler, safer way to manage pain after this major surgery.
What could go wrong
This is a small, early-stage study with only 60 participants, so results may not apply to all patients. The nerve block might not control pain as effectively as the standard epidural approach.

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 60 people

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