Brief summary: The purpose of this study is to evaluate the use of intranasal dexmedetomidine to reduce the incidence of emergence delirium during general sevoflurane anesthesia in a pediatric population receiving pressure equalization tubes in one or more ear.

Detailed description: Emergence delirium has been described as a dissociated state of consciousness in which the child is irritable, uncompromising, uncooperative, incoherent, inconsolably crying, moaning, kicking or thrashing. The children can run the gambit from restlessness and incoherence to combative and psychotic. The incidence of emergence agitation or delirium is 80% after a procedure with sevoflurane-induced anesthesia.

Dexmedetomidine has been shown to have sedative and analgesic effects. In the pediatric population, it has been shown to provide sedation for radiographic procedures. Intravenously, it is has been shown to decrease emergence delirium following sevoflurane based anesthesia. The ability to administer a medication intranasally might solve the problem of emergence delirium and emergence agitation posed by the young patients undergoing myringotomy and tube placement.

Eligibility criteria: Inclusion Criteria:

* ASA class 1 or 2 (healthy patient or acute illness)
* Parental willingness to participate

Exclusion Criteria:

* ASA class 3 or 4 (chronic illness or life-threatening illness)
* Parental refusal to participate
* Significant liver disease by history
* Allergy to dexmedetomidine or midazolam
* Nasal deformity
* Fever in the three days prior to surgery
* Nausea or vomiting
* History of hypertension
* History of cardiac dysfunction/disorder
* Diabetes mellitus
