Comparison of duration of postoperative analgesia of ultrasound guided quadratus lumborum block vs transversus abdominis plane block using 0.25% bupivacaine in laparoscopic surgeries – a one year hospital based randomised clinical trial

Abstract

Background: Laparoscopic surgeries are popular over laparotomy due to its various benefits such as early recovery, less postoperative pain, etc. But they are not completely pain free. Various multimodal analgesia are used such as preemptive analgesia, NSAIDS, opioids, regional anesthesia, peripheral nerve blockade etc. Nowadays, Truncal blocks are more preferred due to its high rates of success with advancement of USG and lesser side effects. Aims & objectives: To compare the duration of postoperative analgesia of ultrasound guided quadratus lumborum block (QLB) versus transversus abdominis plane (TAPB) block using 0.25% bupivacaine in laparoscopic surgeries based on the VAS scores, changes in HR, BP to identify the postoperative pain and efficacy of the blocks
