Intrathecal Dexmedetomidine Versus Transversus Abdominus Plane Block (TAP) for Postoperative Analgesia After Cesarean Section.

Spinal anesthesia is the most commonly used technique for lower abdominal surgeries as it is very economical and easy to administer. However, postoperative pain control is a major problem because spinal anesthesia using only local anesthetics is associated with relatively short duration of action, and thus early analgesic intervention is needed in the postoperative period The transversus abdominus plane (TAP) block is a regional analgesic technique which blocks T6-L1 nerve branches and has an evolving role in postoperative analgesia for lower abdominal surgeries
