The aim of this study is to investigate the postoperative analgesic efficacy of bilateral ultrasonography (US) guided TAP block in patients scheduled for laparoscopic sleeve gastrectomy. Method: In this randomized prospective study; 48 patients, 18-65 years, ASA I-II, morbidly obese (BMI>35), underwent laparoscopic sleeve gastrectomy were included. The patients randomized into two groups: TAP block Group (group TAP) and Control Group (group C). At the end of the operation, bilateral TAP block were performed to 24 patients in Group TAP with a total 40 ml of local solution. 20 ml of local solution was injected into the trocar incision lines of all patients. Patient-controlled analgesia was administered to all patients at a dose of 5 mg/ml tramadol. Tramadol consumption, visual analogue scores (VAS) and the need of rescue analgesia (paracetamol) of the patients at postoperative first 24th hours were recorded. Results: There is no statistical difference in terms of demographic data. Total tramadol consumption and VAS were significantly higher in the Group C (p<0.01). No complications were found in either group.
