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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

Breast reduction surgery causes significant early pain, and doctors want to know which regional pain technique works best. This study compares two ultrasound-guided nerve blocks, PECS II and serratus anterior plane, against standard tumescent local anesthetic infiltration in 60 patients aged 18 to 70. Researchers track opioid consumption, pain scores, and recovery quality in the first 24 hours to see which approach minimizes painkiller needs and supports faster recovery.

What this could mean

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

Active substance
ultrasound-guided nerve blocks (PECS II and serratus anterior plane) versus tumescent local anesthetic infiltration
What this could lead to
If one approach works better, it could shape pain protocols that cut opioid use and speed recovery after breast reduction surgery.
What could go wrong
This is a small observational study of 60 patients at a single center, so results may not apply broadly. Nerve blocks carry small risks of bleeding, infection, or nerve irritation, and individual pain experiences vary widely.

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 60 people
