The patients planned to go under elective cesarean delivery under general anesthesia are randomly assigned to have either bilateral transversus abdominis plane (TAP) block or usual standard analgesics after cesarean. Pain score (Verbal Analog Scale VAS) and analgesic requirements are recorded. It's supposed that both are significantly reduced in patients undergoing TAP block.

Condition Intervention
Postoperative Pain Procedure: TAP blockade

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Investigator)
Primary Purpose: Treatment
Official Title: Evaluation of the Effect of Bilateral Transversus Abdominis Plane Block on Postoperative Pain Intensity and Analgesia Consumption After Elective Cesarean Delivery
