Serratus Posterior Superior Intercostal Plane Block
Serratus Posterior Superior Intercostal Plane Block: An ultrasound-guided interfascial plane block performed between the serratus posterior superior muscle and the underlying ribs prior to general anesthesia.
Study summary
This prospective, randomized, assessor-blinded trial compares serratus posterior superior intercostal plane block (SPSIPB) and erector spinae plane block (ESPB) for postoperative analgesia in unilateral breast surgery. 54 patients will be randomized to receive either SPSIPB or ESPB before general anesthesia.
The primary outcome is postoperative pain scores within the first 24 hours. The secondary outcome is opioid consumption.

Primary outcome measure(s)
Postoperative Pain Scores (NRS) — T0: upon arrival at recovery (Aldrete ≥9), T1: 1 hour, T2: 4 hours, T3: 8 hours, T4: 12 hours, T5: 24 hours postoperatively Postoperative pain intensity will be assessed using the Numerical Rating Scale (NRS; 0-10, where 0 indicates no pain and 10 indicates worst imaginable pain). Pain scores will be evaluated both at rest and during movement (coughing)
