The Effect of a Reduced Noise Environment on Induction and Emergence Behavior in Children Undergoing General Anesthesia

This project will investigate whether reduction in ambient light and elimination of noise on induction of anesthesia alters anxiety (modified Yale Preoperative Anxiety Scale or mYPAS) or compliance (induction compliance checklist or ICC scoring), alters recovery following emergence using pain scores, analgesic requirements, and emergence delirium (post anesthesia emergence delirium or PAED), or post-discharge behavior at 1, 7 and 14 days (modified post hospitalization behaviour questionnaire or PHBQ) in patients who receive anxiolytic premedication. In addition, the investigators will assess the cumulative level of nose exposure that patients experience during the perioperative period.
