N/A Background: The tonsillar region is innervated by the sensory components of the glossopharyngeal nerve(IX) which communicates with certain part of cervical sympathetic ganglion. Some authors suggest stellate ganglion block(SGB) is effective for treatment of recurrent tonsillitis. The goal of this study was to evaluate the effect of SGB in controlling pain after tonsillectomy. Methods: Forty five patients, evaluated to ASA class 1 and 2, scheduled for tonsillectomy under general anesthesia were randomly assigned to 1 of 3 groups (group I: control; group II: SGB with 1% lidocaine 5 ml; group m: SGB with 2% lidocaine 2.5 ml plus 0.5% bupivacaine 2.5 ml), SGB was performed at the end of surgery. Postoperative pain was assessed with Numeric Rating Scale(NRS) NRS assessment was made 30, 60, 90 min, 2 h, 4 h, 24 h, 48 h after tonsillectomy. Results: Pain scores, after 30 min in group II, III and 60, 90 min in group III were significantly lower than group I(p<0.05). Conclusions: We found SGB was effective in controlling pain after tonsillectomy but further studies are required needs to prolong duration of relief.
