SPSIPB Versus SAPB for Postoperative Analgesia After Minimally Invasive Repair of Pectus Excavatum
Sponsor: Marmara University
Summary
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.

Interventions
Postoperative Analgesia Protocol
All participants will receive a standardized multimodal postoperative analgesia protocol. Patient-controlled analgesia with intravenous morphine will be used. The device will be programmed to administer 1 mg of intravenous morphine per demand, with a lockout interval of 10 minutes. Paracetamol will be administered as part of routine multimodal analgesia. If adequate analgesia cannot be achieved, 100 mg tramadol will be administered as rescue analgesia according to clinical need.
Bispectral Index Monitoring
Continuous intraoperative depth of anesthesia monitoring using the Bispectral Index (BIS) device. BIS values are recorded throughout the procedure to assist in titration of anesthetic agents and to standardize anesthesia depth across study cohorts. The BIS device is used for monitoring only, and no device-related investigational procedures are performed.
Serratus Posterior Superior Intercostal Plane Block
Bilateral ultrasound-guided serratus posterior superior intercostal plane block will be performed according to standard techniques described in the literature and routinely used in the clinic. Local anesthetic dosing will be determined according to institutional practice and safety limits. In bilateral applications, the total bupivacaine dose will not exceed 2.5 mg/kg.
Serratus Anterior Plane Block
Bilateral ultrasound-guided serratus anterior plane block will be performed according to standard techniques described in the literature and routinely used in the clinic. Local anesthetic dosing will be determined according to institutional practice and safety limits. In bilateral applications, the total bupivacaine dose will not exceed 2.5 mg/kg.
