This study is a prospective randomized controlled trial designed to compare the effectiveness of the erector spinae plane (ESP) block versus the transversus abdominis plane (TAP) block for postoperative analgesia in patients undergoing cesarean section under spinal anesthesia. Sixty patients will be randomly allocated into two equal groups to receive either ESP or TAP block after surgery. The primary outcome of the study is the assessment of postoperative pain using the Numeric Rating Scale (NRS) over the first 24 hours. Secondary outcomes include total morphine consumption, time to first request for rescue analgesia, patient satisfaction, incidence of complications, and hemodynamic stability. All patients will receive standardized spinal anesthesia followed by the assigned block using a combination of bupivacaine and lidocaine under ultrasound guidance. Postoperatively, a multimodal analgesic regimen will be applied, including regular paracetamol and rescue analgesia with ketorolac or morphine based on pain scores. The rationale of the study is based on the limitation of the TAP block in providing only somatic analgesia, whereas the ESP block may offer both somatic and visceral pain control due to its wider spread. Therefore, the study aims to determine whether ESP block provides superior postoperative analgesia and reduces opioid requirements compared to TAP block after cesarean delivery.

Postoperative pain scores assessment using the Numeric Rating Scale (NRS).
Timeframe: Postoperative pain scores will be assessed using the Numeric Rating Scale (NRS) at 2, 4, 6, 12 and 24 hours only.
