Effect of transversus abdominis plane block combined with low-dose dexmedetomidine on elderly patients undergoing laparoscopic colectomy.

Introduction: Colon cancer is a common malignancy, for which surgery is currently the preferred therapy.

Aim: To assess the effect of transversus abdominis plane block (TAPB) combined with low-dose dexmedetomidine on elderly patients undergoing laparoscopic colectomy.

Material And Methods: Sixty-two elderly patients undergoing laparoscopic colectomy between March 2021 and March 2022 were randomly selected and equally divided into Group A (low-dose dexmedetomidine) and Group B (TAPB + low-dose dexmedetomidine) by the randomized double-blind method.

Optimal Dose of Dexmedetomidine for Preemptive Analgesia Combined with Transversus Abdominis Plane Block after Colon Cancer Surgery.

Background: Pain after colon cancer surgery can be effectively relieved by transversus abdominis plane (TAP) block. We aimed to determine the optimal dose of dexmedetomidine for preemptive analgesia when combined with TAP block after colon cancer surgery.

Methods: A total of 120 patients undergoing laparoscopic resection for colon cancer from March 2018 to October 2019 were randomly assigned to control (group C), low-dose (group L, 0.
