To compare the postoperative analgesic effect of two doses of dexamethasone added to bupivacaine in ultrasound-guided TAP block for inguinal hernia repair.
The transverses abdominis plane block (TAP block) is a regional anesthesia technique that provides analgesia following abdominal surgery . The TAP block significantly reduces pain after open inguinal hernia repair, regardless of whether it is used as a primary anesthesia technique or as a complement to general anesthesia, spinal or local anesthesia . The investigators designed this study to compare the postoperative analgesic effect of two doses of dexamethasone( 4 mg and 8 mg ) added to bupivacaine in ultrasound-guided TAP block for inguinal hernia repair.
