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.
