Brief Summary
This randomized, prospective, single-blinded study aims to compare the efficacy of ultrasound-guided serratus anterior plane (SAP) block combined with serratus-intercostal interfascial plane (SIP) block versus local wound infiltration (LWI) for postoperative analgesia in patients undergoing minimally invasive cardiac surgery (MICS). The primary outcome is total perioperative and postoperative opioid consumption. Secondary outcomes include postoperative pain scores (NRS), opioid-related side effects, block-related complications, and ICU stay duration.
