SPSIP Block and Opioid Use After MICS

This prospective, randomized, controlled, single-center clinical study aims to evaluate the effectiveness of the Serratus Posterior Superior Intercostal Plane Block (SPSIPB) in perioperative pain management among patients undergoing minimally invasive cardiac surgery (MICS). A total of 50 patients undergoing MICS will be randomized into two groups: one receiving standard analgesia plus ultrasound-guided SPSIPB with 30 mL of 0.25% bupivacaine, and a control group receiving standard analgesia only. The primary outcome is total postoperative opioid consumption within 24 hours. Secondary outcomes include postoperative pain scores, extubation time, block-related complications, and recovery parameters such as early mobilization, oral intake, Modified radiological atelectasis score and Quality of Recovery-15 scores.
