Efficacy and Safety of Adding Dexmedetomidine to Levobupivacaine in Rectus Sheath Block Compared to Quadratus Lumborum Block in Patients Undergoing Lower Abdominal Cancer Surgery: A Randomized Clinical Trial

Surgical trauma activates numerous receptors leading to severe postoperative pain. Seventy to seventy-five percent of the pain is somatic, originating from the anterior abdominal wall, and it often persists for 72 hours after open surgery. The objective of this study is to compare the efficacy and safety of adding dexmedetomidine to Levobupivacaine in rectus sheath block with quadrates lumborum block in patients undergoing lower abdominal cancer surgeries.
