Nasotracheal intubation with the McGrath videolaryngoscope in patients with limited mouth opening

Abstract

Limited mouth opening is an important contributing factor to difficult tracheal intubation. Existing guidelines recommend the use of awake techniques but they are often badly tolerated by patients who sometimes refuse consent. We present three patients with limited mouth opening but with no other criteria for difficult airway management and normal upper airway imaging, who refused awake techniques. They were managed with general anaesthesia and nasotracheal intubation using the McGrath series 5 videolaryngoscope.
