The hypothesis of this study is that the application of the bupivacaine-infused fibrin sealant will 1) reduce post-operative mean pain scores in children undergoing tonsillectomy or adenotonsillectomy using a validated pediatric pain scoring system, 2) reduce post-operative hemorrhage rates, 3) reduce post-operative vomiting, 4) reduce total doses of post-operative pain medication and narcotic pain medication required, and 5) expedite recovery as determined by return to normal diet and activity level.
