The goal of this study is to determine if preoperative temperament is associated with postoperative pain, emergence agitation, emotional and behavioral changes, and overall parent satisfaction. This is a prospective observational study to assess preoperative temperament in pediatric patients undergoing tonsillectomy and adenoidectomy, gather demographic data, intraoperative data regarding surgical and anesthetic technique, and collect immediate postoperative data to assess pain, emergence agitation (EA), parental satisfaction as well as remote postoperative data to assess emotional and behavior changes. These data will be used to determine if patients with a specific temperament profile are more likely to experience increased pain, emergence agitation, emotional changes, and behavioral disturbances postoperatively.
