Comparing the postoperative analgesic efficacy of Quadratus Lumborum block vs Transverse Abdominis plane block in patients undergoing elective unilateral open inguinal hernia repair surgeries:a randomised controlled trial

We will compare the quadratus lumborum (QL) block and transversus abdominis plane (TAP) block in unilateral open inguinal hernia repair surgeries.TAP block mainly anaesthesizes the somatic nerves supplying the anterior abdominal wall.The QL block spread to paravertebral space and can be useful for both somatic and visceral pain. so we hypothesize that QL block is better than TAP block in inguinal hernia repair surgeries.we will compare the analgesic efficacy by estimating the duration of analgesia in two groups .In case of pain the patients will be supplemented with inj.tramadol.
