Summary

The advent of laparotomy replacement by minimally invasive techniques brought the obvious benefit of postoperative pain reduction. The application of transversus abdominis block has already demonstrated to reduce postoperative pain in laparoscopic hysterectomy. The comparison between it and quadratus lumborum block in cesarean sections showed that the latter was superior in relation to postoperative analgesia. The aim of this trial is to compare postoperative analgesia in patients receiving one or the other of these regional anesthesia techniques to prevent postoperative pain in gynecological laparoscopic surgeries. The recruited sample will be randomly distributed in three groups to receive placebo, transverse abdominal plan block or quadratus lumborum block, in a covert way for the patients and team. The primary outcome evaluated will be the postoperative consumption of opioid and the secondary outcome will be the evaluation of postoperative pain scores.
