Transverse vs Longitudinal Serratus Anterior Plane Block for Breast Surgery

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This prospective, randomized trial compares two ultrasound probe orientations for the serratus anterior plane block in adults undergoing elective breast surgery. The study aims to see if the longitudinal approach, with the probe parallel to the ribs, spreads the anesthetic more effectively and reduces postoperative pain and opioid use compared with the transverse approach. Participants are adults 18–65 with ASA I–III, undergoing breast surgery, and are randomized to receive either the transverse or longitudinal SAP block. Outcomes include postoperative pain scores and analgesic consumption, measured via standard pain scales and medication usage. The trial is led by Ankara Etlik City Hospital without listed collaborators at a single site in Ankara, Turkey.
