Dexmedetomidine sedation for awake fiberoptic intubation

Abstract

The awake fiberoptic intubation (AFI) is an important part of the anesthesiologist’s armamentarium. As well as being technically challenging, it is also uncomfortable and stressful for all involved. We discuss the use of an alpha-2 agonist, dexmedetomidine, to help the clinician and patient through this procedure. The advantages of dexmedetomidine are that it produces a unique “Cooperative Sedation,” which reduces discomfort in the patient and assists in the topicalization of the airway. Most importantly, dexmedetomidine does not produce significant respiratory depression, so the airway may be secured in the safest manner possible. We discuss the history of sedation for AFI, other medications, as well as guidelines and pitfalls in the use of dexmedetomidine.
