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 Results may not be published yet.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

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.

Summary

This study compares two types of nerve blocks (SAP and SPSIP) to see which one provides better pain relief after mammoplasty (breast surgery). Sixty women aged 18-85 will receive one of the blocks along with a numbing medicine (bupivacaine). Researchers will measure pain scores, opioid use, and satisfaction over 24 hours after surgery.

What this could mean

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

Active substance
Bupivacaine
What this could lead to
If one block works better, it could lead to less pain and less need for strong painkillers after breast surgery.
What could go wrong
This is a small, early-stage study with only 60 people. The results may not apply to everyone, and both blocks may work similarly.

This is an AI summary of the original study and may miss details. Read our disclaimer.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.
