Effect of Transversus Abdominis Plane (TAP) Block Using Magnesium Sulfate Added to Dexamethasone on Quality of Recovery and Chronic Post Operative Pain Following Open Abdominal Cancer Surgery.
Effect of Magnesium Sulfate Added to Dexamethasone-Augmented Ultrasound-Guided Transversus Abdominis Plane (TAP) Block on Early Quality of Recovery and Chronic Post Operative Pain Following Open Abdominal Cancer Surgery: A Prospective Randomized Double-Blind Controlled Trial
This prospective, randomized, double-blind, controlled clinical trial is designed to evaluate whether adding magnesium sulfate to a dexamethasone-augmented, ultrasound-guided transversus abdominis plane (TAP) block improves early postoperative recovery and analgesia in adult patients undergoing open abdominal cancer surgery.
A total of 72 participants will be allocated into two groups. Both groups will receive a standard TAP block using bupivacaine and dexamethasone, while the intervention group will additionally receive magnesium sulfate.
The primary outcome of the study is the early quality of recovery assessed at 24 hours postoperatively. Secondary outcomes include postoperative pain scores, total opioid consumption, time to first rescue analgesia, the incidence of postoperative nausea and vomiting, patient satisfaction, block-related complications, intraoperative opioid requirements, hemodynamic parameters, and the incidence of chronic postoperative pain assessed through six months of follow-up.

Quality of Recovery-15 (QoR-15) score
Prazo: 24 hours postoperatively

The Quality of Recovery-15 questionnaire will be used to assess the quality of postoperative recovery 24 hours after surgery, evaluating five dimensions: physical comfort, emotional state, psychological support, physical independence, and pain, resulting in a total score ranging from 0 to 150 (higher scores indicate better recovery). |
