MAC video laryngoscope (McG) has been used for orotracheal intubation in both normal patients and patients for whom intubation was expected to be difficult, and has been reported to provide improved visibility of the glottis during tracheal intubation. There are some reports that normal nasotracheal intubation is easier with McG than with macintosh laryngoscope (ML). The usefulness of McG for nasotracheal intubation is beginning to be recognised. We experienced three cases using McG in patients for whom intubation was expected to be difficult due to the limited mouth opening and using McG for those patients enabled smooth nasotracheal intubation. McG provides good visual field during nasotracheal intubation, and is less invasive to the patient.展开更多
