The Quest for Opioid-Free Analgesia in Reduction Mammoplasty: A Comparative Analysis of PECS, SAP Blocks, and Tumescent Infiltration

Reduction mammoplasty is associated with significant early postoperative pain due to the extent of the incision and glandular resection. Effective regional analgesia may reduce opioid requirements; ultrasound-guided pectoral nerve block type II (PECS II), serratus anterior plane block (SAPS) and surgeon-administered local anesthetic wound infiltration. This is a multi-center, prospective observational study in patients aged 18-70 years (ASA I-III) scheduled for elective reduction mammoplasty. The investigators will compare the two routinely applied techniques with respect to perioperative opioid consumption (primary outcome), postoperative pain scores on the Numeric Rating Scale, total rescue analgesic dose within the first 24 postoperative hours. A minimum of 58 patients will be enrolled based on a priori power analysis. The aim is to determine which of the two existing analgesia protocols better minimizes postoperative analgesic consumption and supports early recovery, in order to inform future pain management protocols.
