Transversus Abdominis Plane Block in the Management of Acute Postoperative Pain Syndrome After Caesarean Section

Overview

In many countries, caesarean section (CS) rates have been increasing. The international literature is unclear regarding the analgesic efficacy of the transversus abdominis plane block (TAPB) after a CS. In particular, no clinical trials exist in which the correct method of performing this block has been matched with the obtained analgesic effect after a CS. The primary goal of the study was to determine whether a correctly performed ultrasound-guided TAPB (USG-TAPB) could provide patients who underwent a CS with better control of acute postoperative pain during the first 72 hours after surgery

Transversus abdominis plane block (TAPB) is a regional anesthetic technique that can provide analgesia for lower abdominal surgical procedures. Previous meta-analyses and recently published clinical trials have demonstrated promising results for this technique when it is used as part of multimodal postoperative pain treatment, but no consensus exists regarding the potency of this type of anesthetic procedure for analgesia after a CS. The primary goal of the study was to determine whether a correctly performed ultrasound-guided TAPB (USG-TAPB) could provide patients who underwent a CS with better control of acute postoperative pain during the first 72 hours after surgery. In this study, the correct execution of an USG-TAPB was verified, and then the procedure was matched with the obtained analgesic effect after a CS. The secondary aims were to determine whether USG-TAPB could ensure a decline in postoperative requests for opiates and fewer opiate-related side effects, the return of faster bowel function, and shorter recovery time without generating critical hemodynamic changes.
