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.",[26,27],"Pectus Excavatum","Chest Deformities",[29,30,31,32,33,34,35,36,37,38,39,40],"Pectus excavatum","Serratus Anterior Plane Block","Serratus Posterior Superior Intercostal Plane Block","Opioid-Free Anesthesia","Multimodal Analgesia","SAP Block","SPSIP Block","Postoperative Pain","Opioid-Related Adverse Effects","Opioid Consumption","Chest Deformity Surgery","Regional Anesthesia","RECRUITING","2026-07-06",{"date":44,"type":45},"2026-07-13","ACTUAL",{"date":47,"type":45},"2026-06-22",{"date":49,"type":21},"2027-06",{"name":51,"class":52},"Marmara University","OTHER"]
