The objective of this study is to compare the topical administration of bupivacaine hydrochloride, saline and bupivacaine hydrochloride infiltration on post-tonsillectomy pain in children. Sixty children undergoing tonsillectomy were enrolled in the study. Patients were randomized into three groups using sealed envelopes. Group 1 (n = 20) received topical 0.5 % bupivacaine hydrochloride, group 2 (n = 20) received topical 0.9 % NaCl (saline), and group 3 (n = 20) received 0.5 % bupivacaine hydrochloride infiltrated around each tonsil. Pain was evaluated using McGrath's face scale. Pain scores in topical bupivacaine hydrochloride group was significantly lesser than the topical saline group at 5th, 13th, 17th and 21st hours, until the 6th day (p < 0.017). Moreover, pain scores of topical bupivacaine hydrochloride group was superior to bupivacaine hydrochloride infiltration group at 5th, 13th, 17th hours and 2nd, 3rd, 4th and 5th day (p < 0.017). There were significantly lesser morbidities in topical bupivacaine hydrochloride than saline group in 1st and 4th day (p < 0.017). Topical administration of bupivacaine hydrochloride proved to provide more efficient pain control than bupivacaine hydrochloride infiltration.
