Double-Blinded Randomized Control Trial Comparing Liposomal Bupivacaine and Plain Bupivacaine in Transversus Abdominis Plane For Deep Inferior Epigastric Artery Perforator (DIEP) Flap Breast Reconstruction

Pain control after autologous breast reconstruction is important for patient satisfaction and early recovery. Transversus abdominis plane (TAP) blocks are commonly used as part of an enhanced recovery after surgery (ERAS) pathway for breast reconstruction. It is uncertain whether liposomal bupivacaine used in TAP blocks offers additional advantages. This study aimed to compare the efficacy of liposomal bupivacaine versus plain bupivacaine for patients undergoing deep inferior epigastric perforator flap reconstruction.
