Parents will be present in the room during premedication. The Anesthesia personnel involved in the care of the patient (MD or CRNA) will prepare and administer all study drugs. All patients will be continuously monitored in the holding area with pulse oximetry and blood pressure monitor. HR, SPO2 and BP will be recorded every 15min after administration of premedication until transfer to the OR. Emergency medications including atropine and epinephrine will be immediately available in the pre-op holding area. Oral midazolam has been used with very little effect on hemodynamic parameters. Although intranasal dexmedetomidine can decrease HR and BP, it has been used at the dose of 2mcg/kg without any adverse hemodynamic effect . Any intervention needed to treat drop in HR (<50) and BP (sys BP <60) after the drug administration will be recorded.
