Effectiveness of Liposomal Bupivacaine Transversus Abdominis Plane Block in DIEP Flap Breast Reconstruction: A Randomized Controlled Trial.

Background: Transversus abdominis plane (TAP) blocks improve pain control and reduce narcotic medication requirements in various surgical procedures. Liposomal bupivacaine may provide more sustained analgesia. This study compared pain-related outcomes between standard bupivacaine and liposomal bupivacaine TAP blocks after autologous breast reconstruction.
