Measure
Dexmedetomidine
Dexmedetomidine: Administer dexmedetomidine at 1mcg/kg over 10min followed by an infusion of dexmedetomidine at 1mcg/kg/hr and image the upper airway. After the initial set of images is obtained, the depth of anesthesia will be increased by administering a bolus dose of dexmedetomidine 2mcg/kg followed by increase in the infusion rate to 3mcg/kg/hr. Upper airway images will be repeated 5mins after increasing infusion Image acquisitions will be repeated approximately 5 min after the increase in infusion rate.
Propofol
propofol: Administer propofol bolus at 2mg/kg,followed by an infusion of propofol at 100 mcg/kg/min. Upper airway images will be obtained 5 mins after the patient is stable on this infusion. After the initial set of images is obtained, the depth of anesthesia will be increased by administering a bolus dose of 1mg/kg propofol and infusion increased to 240mcg/kg/min. Image acquisitions will be repeated approximately 5 min after the increase in infusion rate.
