SPSIPB Versus SAPB for Postoperative Analgesia After Minimally Invasive Repair of Pectus Excavatum

Recruiting now

Conditions studied: Pectus Excavatum, Chest Deformities

In brief

This prospective observational cohort study will compare postoperative analgesic outcomes in patients undergoing minimally invasive repair of pectus excavatum. Participants will be grouped according to the regional analgesia technique applied as part of routine clinical care: serratus posterior superior intercostal plane block or serratus anterior plane block. The primary outcome will be total opioid consumption during the first 24 hours after surgery. Secondary outcomes will include postoperative pain scores, rescue analgesic requirement, opioid-related adverse effects, patient satisfaction, mobilization time, and length of hospital stay.
