A Comparative Study between Ultrasound Guided Trans-muscular Quadratus Lumborum Block Versus Ultrasound Guided Transversus Abdominis Plane Block as postoperative analgesia in Laparoscopic Bariatric Surgery

Abstract

variety of unwanted post-operative consequences, including patient suffering, distress, respiratory complications, delirium, myocardial ischemia, prolonged hospital stay and an increased likelihood of chronic pain due to poorly controlled acute pain after laparoscopic abdominal surgery. The goals of providing safe, effective analgesia, with minimal side effects for the patient, together with inhibition of trauma-induced nociceptive impulses are the analgesic regimen need to be met. Many studies provide different pain modalities as local infiltration of the surgical field, systemic analgesia (narcotics and non-narcotics), neuro-axial blocks, and nerve blocks shined out, however each has shown its side effect that limits its use to specific cases. Abdominal field blocks are simple to perform and have a good safety profile, also have been extensively used for a variety of surgical procedures for many years
