A Case in Which the Tracheal Intubation Route was Changed from Oral to Nasal Using a McGRATH^TM MAC, a Fiberoptic Bronchoscope Tube, and a Tube Exchanger

Abstract

  A patient with multiple facial traumas was orally intubated. Ten days after intubation, a change in the intubation route (from oral to nasal) was performed prior to surgery. Due to anticipated damage, contamination, and bleeding in the oral cavity, the procedure was performed using a video laryngoscope (McGRATH^TM MAC), a bronchial fiberscope, and a tube exchanger. The procedure was conducted under general anesthesia while preserving spontaneous breathing and was completed without a decrease in SpO₂. A detailed plan and careful procedure are important when changing the intubation route in cases with airway abnormalities.
