What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study

Summary

This trial tests whether the angle of the ultrasound probe during a nerve block affects pain relief after breast surgery. About 70 adults scheduled for breast surgery will receive a serratus anterior plane block with bupivacaine, using either a transverse or longitudinal probe orientation. The study will compare pain scores and opioid use in the first 24 hours after surgery to see if one approach provides better pain control.

What this could mean

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

Active substance
Serratus anterior plane block with bupivacaine, performed using either a transverse or longitudinal ultrasound probe orientation
What this could lead to
If one probe angle proves better, it could lead to a simple change in technique that improves pain control and reduces opioid use after breast surgery.
What could go wrong
This is a small, early-stage trial, so results may not apply to all patients. The benefit of one angle over the other may be small, and nerve blocks carry risks like infection or allergic reaction.
