Pilot: Intraoperative TAP Block and Post-operative Pain Control for Minimally Invasive Hysterectomy for Endometrial Cancer

"Liposomal bupivacaine is FDA-approved for use single-dose infiltration in adults to produce postsurgical local analgesia and as an interscalene brachial plexus nerve block to produce postsurgical regional analgesia.~The solution will be placed into 20 mL syringes on 18-gauge needles for injection. The injections will be performed percutaneously by the surgeon along the midaxillary line at 4 equidistant points from the anterior superior iliac spine to the costal margin, as well as a single injection subcostally at the anterior axillary line. 20 mL will be injected at each site, 5 sites per side bilaterally, total of 10 sites. The depth of injection will be judged by laparoscopic visualization of a diffuse bulge during injection, indicating injection in the correct plane, just superficial to the transversus abdominis muscle."
