Anesthesia and Analgesia: Postoperative AnalgesiaTransversus Abdominis Plane Block and Intrathecal Morphine Use in Cesarean Section: A Retrospective ReviewCole, J.; Hughey, S.; Longwell, J.Author Information Department of Anesthesiology and Pain Medicine, Naval Medical Center Portsmouth, Portsmouth, VA Obstetric Anesthesia Digest: September 2020 - Volume 40 - Issue 3 - p 166 doi: 10.1097/01.aoa.0000693860.30940.99 Buy Metrics Abstract (Reg Anesth Pain Med. 2019;44:1035–1037) In women undergoing cesarean delivery, the anesthesia technique is most commonly spinal or epidural anesthesia. Postoperative pain is most frequently managed by administering morphine into the intrathecal or epidural space. However, transversus abdominis plane (TAP) block can also be utilized. While both modalities, used separately, have been shown to be effective in managing pain after surgery, the literature on the combined use of intrathecal morphine and TAP block needs further investigation. The aim of this study was to evaluate whether the TAP block in combination with intrathecal morphine delays the need to initiate opioid administration following cesarean delivery under spinal anesthesia, versus intrathecal morphine alone.
