Background: Post-tonsillectomy pain is one of the most common problems after anesthesia, therefore use of a good anesthesia technique with minimum side effect is an important aim. This study was performed to compare the efficacy of peritonsillar infiltration of bupivacaine, tramadol and combination of bupivacaine-tramadol in post-tonsillectomy pain.
Materials And Methods: In a double blind trial 120 ASA I and II children condidated for tonsillectomy were randomized into four groups: Peritonsillar infiltration with bupivacaine 1 mg/kg in Group B, tramadol 2 mg/kg in Group T, combination of bupivacaine-tramadol in Group BT and saline in Group C was done.
