Serratus Posterior Superior Intercostal Plane Block Versus Intrathecal Morphine in VATS
Sponsor: Ondokuz Mayıs University
Summary
This study aims to compare the analgesic effects of the serratus posterior superior intercostal plane block and intrathecal morphine in patients undergoing video-assisted thoracoscopic surgery. This is a prospective, randomized, controlled, single-center clinical trial including adult patients undergoing elective thoracoscopic surgery. Participants will be randomly assigned to receive either a serratus posterior superior intercostal plane block or intrathecal morphine before general anesthesia. The primary outcome is cumulative opioid consumption during the first 24 postoperative hours, expressed as intravenous morphine milligram equivalents. Secondary outcomes include pain scores, time to first analgesic request, quality of recovery, and postoperative complications. The study aims to determine whether these two techniques differ in their effectiveness for postoperative pain management.

Interventions
Intrathecal Morphine
Preservative-free morphine at 5 µg/kg based on ideal body weight is diluted with 0.9% saline to a total volume of 3 mL and administered intrathecally before induction of general anesthesia.
Serratus Posterior Superior Intercostal Plane Block
Ultrasound-guided serratus posterior superior intercostal plane block is performed before induction of general anesthesia using 30 milliliters of 0.25 percent bupivacaine with epinephrine injected into the interfascial plane between the serratus posterior superior muscle and intercostal muscles.
