In plain words

What the trial is, and whether it could suit you

This prospective, randomized, active-controlled, double-blind, parallel-group study compares the postoperative analgesic efficacy and safety of ultrasound-guided bilateral Erector Spinae Plane Block (ESPB) versus bilateral Serratus Posterior Superior Intercostal Plane Block (SPSIPB) in adult patients (45-85 years, ASA I-III) undergoing elective coronary artery bypass graft surgery. The primary outcome is postoperative pain intensity assessed by Numeric Rating Scale (NRS) at 2, 4, 8, 16, 24, and 48 hours after surgery. Secondary outcomes include intraoperative fentanyl/remifentanil consumption, postoperative morphine consumption, patient-controlled analgesia (PCA) demand/delivery parameters (if PCA is used), need for rescue analgesics, extubation and mobilization times, peak inspiratory flow measured by incentive spirometry at predefined time points, ICU and hospital length of stay, recov
