This clinical trial aims to determine the optimal timing for administering a Transversus Abdominis Plane (TAP) block in bariatric surgery, specifically investigating whether initiating TAP blocks at the beginning of surgery is more beneficial than at the end, which is the current practice. The study targets obese patients undergoing bariatric surgery, with a focus on reducing postoperative pain and opioid use. Key outcomes include recovery duration, pain levels, opioid consumption, and respiratory function. Successful results could establish early TAP block initiation as a standard practice, offering faster recovery, decreased opioid reliance, and reduced healthcare costs.
