Airway Management with Dexmedetomidine and High-Flow Nasal Cannula in a Patient with Deep Neck Infection.

Retropharyngeal deep neck infection sometimes necessitates securing of the airway and surgery for drainage. Airway management in patients with deep neck infection is challenging for anesthesiologists. A 56-year-old woman diagnosed with deep neck infection was admitted for incision and drainage. In the first operation for incision and drainage, indirect videolaryngoscope was utilized to confirm the airway before tracheal intubation, and the patient was intubated successfully. In the second operation for wound closure, dexmedetomidine administration and high-flow nasal cannulation were used during monitored anesthesia care throughout a subsequent procedure. The outcome in the present case suggests that indirect videolaryngoscope, dexmedetomidine, and high-flow nasal cannula can facilitate effective management during surgery in patients with retropharyngeal deep neck space infection.
