Laparoscopic-guided TAP Block in Patients Undergoing Gastric Bypass
Laparoscopic-guided TAP Block in Patients Undergoing Gastric Bypass
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.
