Clinical Trial Summary

This study will compare the efficiency of transversus abominus plane (TAP) block using liposomal bupivacaine versus plain bupivacaine that is administered in the operating room under ultrasound guidance prior to the in patients undergoing abdominally-based free flap breast reconstruction at Vanderbilt University Medical Center.


Clinical Trial Description

Transversus Abdominis Plane (TAP) blocks are commonly used as part of Enhanced Recovery After Surgery (ERAS) pathway. This prospective, double-blinded, randomized control trial compares post-operative pain and narcotic consumption after deep inferior epigastric artery perforator (DIEP) breast reconstruction with liposomal bupivacaine (LB) compared to bupivacaine hydrochloride (BHCl). Subjects undergoing DIEP flaps were randomly assigned LB or BHCl, performed using ultrasound-guided TAP block technique pre-procedurally. Primary outcomes were postoperative narcotic analgesia required in oral morphine equivalents (OME) from postoperative day (POD) 0 to 7. Secondary outcomes included POD 1-7 pain Numeric Rating Scale (NRS), non-narcotic pain medication consumption, time to first narcotic use, return of bowel function, and length of stay (LOS). ;
