Comparisons Between Low Thoracic and Lumbar Epidural Analgesia on Postoperative Pain Management Qualities After Cesarean Delivery: a Randomized Controlled Trial

Postoperative pain remains the leading cause of concern in women faced with undergoing a cesarean delivery. Inadequate acute pain management is associated with numerous negative effects, including delayed postpartum recovery, interference with mother-child bonding because postoperative pain limits breastfeeding, and a high risk of postpartum depression and persistent pain.

Epidural analgesia (EA) is being increasingly preferred to systemic opioid because of better analgesic effect. Although EA is widely used for cesarean delivery, the effect of the site of epidural catheter insertion on the quality of postoperative pain management remains inadequately investigated. For example, placement of the epidural catheter in the low thoracic intervertebral spaces may be more suitable for catheter-incision-congruent analgesia during caesarean delivery than in the lumbar intervertebral space; however, epidural catheter insertion is conventionally recommended at the lumbar intervertebral space. Therefore, in this study, we aim to investigate the difference in post-cesarean pain control quality between low thoracic EA and lumbar EA.
