Recovery Quality of Transversus Abdominis Plane Block With Liposomal Bupivacaine After Cesarean Delivery: A Randomized Trial

( J Clin Anesth . 2024;99:111608. doi: 10.1016/j.jclinane.2024.111608) Cesarean eliveries (CDs) accounted for nearly half of all deliveries in China in 2020 (44.5%), which distinguishes the procedure as one of the most common among women. Many individuals who undergo this procedure experience postoperative pain, and subsequent management of pain is a large part of postpartum recovery for these patients. Most common analgesics during the procedure are epidural analgesia and intrathecal opioid analgesia. A newer method is multimodal analgesia that incorporates both nerve blocks, including transversus abdominis plane (TAP) blocks, and opioid medications. This study was designed to evaluate recovery quality in women who had CDs with TAP blocks and liposomal bupivacaine (LB) medication, with the hypothesis that TAP blocks using LB either alone or in combination with normal bupivacaine would lead to better recovery than bupivacaine alone over the first 24 hours of recovery.
