ltrasound-guided transversus abdominis plane (TAP) block is an emerging local anesthesia technique that effectively alleviates postoperative pain by injecting anesthetic drugs around the nerves in the abdominal wall.

However, current research on the application of TAP blockade after cesarean section is still limited. Therefore, this study will systematically evaluate its actual effectiveness in pain management after cesarean section through a prospective randomized controlled trial
