We report a series of successful awake fiberoptic intubations in patients with critical (unstable, difficult) airways using the alpha(2)-agonist, dexmedetomidine. Dexmedetomidine has several desirable pharmacologic properties, including sedation, anxiolysis, hypnosis, analgesia, amnesia, antisialagogue effects, and a unique respiratory-sparing effect. Dexmedetomidine appears to be a useful agent for sedation during awake fiberoptic intubation in difficult airway patients.
