AbstractNasotracheal intubation is an essential skill for clinicians involved in the care of acutely ill or injured patients. Unfortunately, it has the dangers and difficulties of any blind technique. Although usually performed in the awake patient, nasotracheal intubation has also been used in the apneic patient. Transillumination of the soft tissues of the neck with a lighted stylet has been shown to be a reliable method of orotracheal intubation. The usefulness of a longer, flexible lighted stylet as an aid to nasotracheal intubation in the apneic patient has been examined. Eighty patients, who were paralyzed, apneic, and about to undergo nasotracheal intubation for elective ear, nose, and throat or maxillofacial surgery were randomized to be nasotracheally intubated blindly or with a stylet by an emergency medicine resident or anesthesiologist. Sixty-three percent intubated in the lighted-stylet group and 41% in the blind nasotracheal intubation group were successfully intubated. There were no significant differences in the time needed to intubate or the number of attempts. There were notable differences in the success rates of individual intubators with each technique. Although not statistically significant, our results suggest a useful role for the lighted stylet in nasotracheal intubation in the apneic patient.
