A prospective randomized trial will be performed. Patients undergoing gastric bypass will be randomized into 2 groups: patients undergoing laparoscopic-guided transversus abdominis plane (TAP) block as part of multimodal analgesia (Group 1), associated with postoperative intravenous analgesia, and patients receiving only postoperative intravenous analgesia (Group 2).
Postoperative pain will be assessed with a Visual Analogic Scale 24h after surgery and morphine needs will be quantified.
A prospective randomized trial will be performed. Patients undergoing laparoscopic Roux-en-Y gastric bypass will be randomized into 2 groups: patients undergoing laparoscopic-guided TAP block with 30 ml Bupivacaine 0.5%, as part of multimodal analgesia (Group 1), associated with postoperative intravenous analgesia (Metamizol 2g/8h and Acetaminophen 1g/8h), and patients receiving only postoperative intravenous analgesia (Metamizol 2g/8h and Acetaminophen 1g/8h) (Group 2).
Postoperative pain will be assessed with a Visual Analogic Scale 24 hours after surgery and morphine needs will be quantified.
