Official title
A Randomized Trial Comparing Erector Spinae Plane Block Versus Serratus Posterior Superior Intercostal Plane Block for Postoperative Analgesic Efficacy in Patients Undergoing Coronary Artery Bypass Graft Surgery
Overview
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, recovery quality (QoR-15 at 0, 24, and 48 hours), mortality, and block-related adverse events.
Interventions
- Procedure Ultrasound-guided Erector Spinae Plane Block (ESPB)
Bilateral ultrasound-guided ESPB performed preoperatively under sedation at the T4-T5 transverse process level using 20 mL of 0.25% bupivacaine per side (total 40 mL). - Procedure Ultrasound-guided Serratus Posterior Superior Intercostal Plane Block (SPSIPB)
Bilateral ultrasound-guided SPSIPB performed preoperatively under sedation at the 2nd-3rd intercostal space using 20 mL of 0.25% bupivacaine per side (total 40 mL).
Primary outcome measures
- Postoperative pain intensity [Time frame: 2, 4, 8, 16, 24, and 48 hours after surgery]
Secondary outcome measures (3)
- Cumulative postoperative opioid consumption [Time frame: First 24 hours after surgery]
- Need for rescue analgesia [Time frame: Up to 48 hours after surgery]
- Quality of Recovery (QoR-15) score [Time frame: Baseline (preoperative), postoperative 24 hours, and 48 hours after surgery]
