REctus Sheath block for postoperative analgesia in gynecological ONcology Surgery (RESONS): a randomized-controlled trial

摘要

Opioid-sparing pain management is important for Enhanced Recovery After Surgery. Rectus sheath (RS) blocks are emerging as a promising modality for pain relief following midline laparotomy; however, there are limited prospective clinical trials testing their efficacy. The purpose of this randomized-controlled trial is to assess the morphine-sparing effect of local anesthetic (LA) boluses through RS catheters following elective gynecological oncology surgery.
