Dexmedetomidine infusion for sedation during fiberoptic intubation: a report of three cases.

We report three patients undergoing cervical spine surgery who required awake fiberoptic intubation, and in whom sedation was provided using a dexmedetomidine infusion. Dexmedetomidine was used to provide a moderate level of sedation without causing respiratory distress or hemodynamic instability during fiberoptic intubation. Conditions for intubation were acceptable in all three patients after co-administration of topical anesthesia. Dexmedetomidine may serve as a useful adjunct for this procedure. The anesthetic management and anesthetic implications of using dexmedetomidine infusions for awake fiberoptic intubation are discussed.
