The aim of this work is to compare the analgesic efficacy of laparoscopic transversus abdominis plane block, performed by the surgeon to ultrasound-guided erector spinae plane block, performed by the anesthetist, in patients with obesity undergoing bariatric surgery.
This is a randomized controlled trial which will include patients with obesity undergoing bariatric surgery. The patients will be randomly allocated into two groups: transversus abdominis plane block group and erector spinae plane block group. The block will be performed after induction of general anesthesia. Preoperative evaluation and preparation will include history-taking, laboratory investigation, fasting recommendations, and optimization of the medical status. The two groups will receive standard induction and maintenance of anesthesia. After the end of the operation, patients will receive standard care according to the local protocols and the enhanced recovery recommendations. Patients will be monitored according to the pain-related outcomes as well as hemodynamic parameters.
