The effectiveness of 0.5% isobaric Bupivacaine+dexmedetomidine vs 0.75% Ropivacaine + dexmedetomidine for Postoperative analgesia using ultrasound guided Transversus abdominis plane block for Abdominal surgeries under general anaesthesia :A randomized control study.

Abstract

ABSTRACT: BACKGROUND: Laparoscopic surgeries have an increased popularity when compared to laparotomy procedures as they have many advantages like less postoperative pain and early recovery. However laparoscopic surgeries are not completely devoid of pain. One such method of analgesia following abdominal surgeries are Transverse Abdominus Plane Blocks (TAPB) performed with the guidance of ultrasound for an accurate block. AIMS AND OBJECTIVES: To compare the duration of postoperative analgesia of ultrasound guided TAP Block using 0.5% Bupivacaine + Dexmedetomidine vs 0.75% Ropivacaine + Dexmedetomidine based on VAS scores. To assess the effect of TAPB on perioperative hemodynamic parameters (HR, NIBP, SpO2)
