Effectiveness of Combined Fascial Plane Blocks for Postoperative Pain in Gynecologic Oncology Surgery

This study is a prospective observational research designed to evaluate the postoperative analgesic effectiveness of different combinations of fascial plane blocks in patients undergoing gynecologic oncology surgery. All blocks (Transversus Abdominis Plane \[TAP\] block, Quadratus Lumborum Block \[QLB\], and Rectus Sheath Block \[RSB\]) were performed as part of routine clinical anesthesia practice according to the attending anesthesiologist's preference. No intervention, randomization, or protocol-directed procedure was applied for research purposes. After data collection, patients were classified into three groups based on the block type they had received in standard care: TAP block only TAP + QLB combination TAP + RSB combination The study prospectively compared postoperative pain scores (VAS), opioid consumption, time to mobilization, bowel function recovery, and length of hospital stay among these groups to determine the most effective analgesic strategy within routine practice. This observational design reflects real-world anesthesia management and does not involve any experimental or interventional component.
