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

Abstract Background A variety of unwanted post-operative consequences, including patient suffering, respiratory distress complications, delirium, myocardial ischemia, prolonged hospital stay and an increased likelihood of chronic pain are due to poorly controlled acute pain after laparoscopic abdominal surgery. Aim of the Work is to compare the analgesic efficacy of ultrasound-guided TQL with TAP block during laparoscopic bariatric surgery and to improve the outcome of the patients undergoing laparoscopic bariatric surgery under general anesthesia who suffer from postoperative pain and also in the early postoperative period regarding pain relief, decreasing postoperative opioid requirements, provision of comfort, early mobilization and improved respiratory functions. Patients and Methods The study was conducted on 40 randomly chosen patients in Ain Shams University Hospitals after approval of the medical ethical committee. They were allocated in two groups of 20 patients each: Group TQL (n = 20): received combined general anesthesia with TQL block. Group TAP (n = 20): received combined general anesthesia with TAP block. Results TQL block has more analgesic efficacy than TAP block. The first call for rescue analgesia (Meperidine), total meperidine consumption and pain scores (visual analog score at rest and movement) indicated the superiority of the analgesic technique TQL block. Conclusion TQL with general anesthesia was more effective technique in providing analgesia after laparoscopic bariatric surgery without associated hemodynamic instability in comparison to TAP block with general anesthesia and also the first call for rescue analgesia (Meperidine), total meperidine consumption and pain scores (visual analog score at rest and movement) indicated the superiority of the analgesic technique TQL block.
