Dexmedetomidine Versus Propofol Sedation for Drug-Induced Sleep Endoscopy in Pediatric Obstructive Sleep Apnea

This research study is designed to learn, first, whether two anesthetics have different effects on collapse seen within the upper airway during sleep endoscopy. A second purpose is to learn whether collapse at several levels of the upper airway is associated with obstructive sleep apnea that persists after adenotonsillectomy, the surgery that removes the tonsils and adenoids.
