Brief summary

Transversus Abdominis Plane Block (TAPB) is frequently used for the management of postoperative pain in patients undergoing cesarean section. Recently, Erector Spinae Plane Block (ESPB) has been defined and used in several clinical scenarios. However, data regarding the ESPB use in the aforementioned patient group is limited.
