A Review of Peripheral Nerve Blocks for Cesarean Delivery Analgesia

( Reg Anesth Pain Med . 2020;45:52–62) Peripheral nerve blocks are used in nonobstetrical surgery as part of a multimodal analgesic strategy. These blocks have been associated with reduced opioid requirements, better quality of recovery, and reduced hospital utilization. Yet, peripheral nerve blocks are not routinely performed for cesarean delivery. This review article discussed several peripheral nerve block options for cesarean delivery, including lumbar sympathetic paravertebral (PVB), transversus abdominis plane (TAP), quadratus lumborum (QL), ilioinguinal-iliohypogastric (II-IH), continuous wound infiltration (CWI), and erector spinae plane blocks.
