Evaluating the Adjuvant Effect of Dexamethasone to Ropivacaine in Transversus Abdominis Plane Block for Inguinal Hernia Repair and Spermatocelectomy: A Randomized Controlled Trial.

Background: The transversus abdominis plane (TAP) block is a relatively straightforward regional technique used for postoperative analgesia in patients undergoing abdominal surgeries. Various adjuvants have been used in past to prolong the duration of action of analgesia in peripheral nerve blocks. Several studies investigating the analgesic efficacy of dexamethasone added to local anesthetic agents, such as bupivacaine, have shown promising results.
