Quadratus lumborum block for postoperative analgesia after full abdominoplasty: a randomized controlled trial.

Background And Aims: The quadratus lumborum block (QLB) provides regional analgesia of the anterior abdominal wall, theoretically matching the postoperative pain after postbariatric standard full abdominoplasty. We investigated the effectiveness of a QLB as an addition to the current multimodal analgesia regimen in postbariatric patients treated with standard full abdominoplasty.

Methods: Randomized, placebo-controlled, triple blinded study ( = 50).
