Serratus Posterior Superior Intercostal Plane BlockUltrasound-guided Erector Spinae 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.
Ultrasound-guided Erector Spinae Plane Block: An ultrasound-guided erector spinae plane block performed prior to induction of general anesthesia using 30 mL of 0.25% bupivacaine.
Study summary
This prospective, randomized, assessor-blinded study will compare serratus posterior superior intercostal plane block and erector spinae plane block in adult female patients undergoing unilateral breast surgery. The primary outcome is chronic postoperative pain at 3 months, assessed using the Brief Pain Inventory-Short Form.

Primary outcome measure(s)
Chronic Postoperative Pain Assessed by the Brief Pain Inventory-Short Form — Time Frame: T0: 3 months postoperatively Chronic postoperative pain will be assessed using the Brief Pain Inventory-Short Form (BPI-SF). The BPI-SF assesses pain severity (worst, least, average, and current pain) and pain interference with daily activities. Pain severity items are scored on a 0-10 numeric rating scale (0 = no pain; 10 = pain as bad as you can imagine). Pain interference items are scored on a 0-10 numeric rating scale (0 = does not interfere; 10 = completely interferes). Higher scores indicate worse pain severity and greater pain-related interference.
