A Comparative Study Of the Analgesics Efficacy of Ultrasound-Guided Quadratus Lumborum Block(QL) VS Transversus Abdominis Plane (TAP)Block For Patients Undergoing Elective Caesarean Section In a Tertiary Care Hospital A Prospective Randomised Double Blinded Study

This study is a prospective randomized double blinded controlled trial being conducted at Sri Sathya Sai Medical College and Research Institute. It aims to compare the analgesic efficacy of ultrasound guided quadratus lumborum block and transversus abdominis plane block in women aged 18 to 40 years with ASA physical status I or II undergoing elective caesarean section under spinal anaesthesia. A total of 70 participants will be randomized into two groups of 35 each. Group QL will receive 20 ml of 0.25 percent bupivacaine bilaterally in the quadratus lumborum block and Group TAP will receive 20 ml of 0.25 percent bupivacaine bilaterally in the transversus abdominis plane block. The primary objective is to compare the duration of effective postoperative analgesia between the two groups using visual analogue scale scores, while secondary objectives include assessing the time to first rescue analgesia, total analgesic consumption, and adverse events. Institutional ethics committee approval has been obtained and written informed consent will be taken from all participants.
