Abstract

Purpose

The purpose of this study was to evaluate the usefulness of Trachlight (TL) for nasotracheal intubation and to determine the relationship between the grade of laryngeal view and the subsequent ease of nasotracheal intubation using TL.

Methods

Patients requiring nasotracheal intubation were enrolled in this study. Laryngoscopy was performed in all patients under topical anesthesia, with 8% lidocaine spray applied to the supraglottic region and the vocal cords. Glottic visualization during laryngoscopy was assessed using the Cormack and Lehane classification. Patients were allocated to four groups according to this classification. If the TL intubation was unsuccessful after three attempts, intubation was carried out using direct laryngoscopy. Intubation difficulty was assessed by the original 6-point scale and the total intubation time was also recorded.

Results

Trachlight intubation was successful in 89.1% of the 110 patients enrolled in the study. There was no observed correlation between the original 6-point scale and glottic visualization. The total intubation time and the ratio of “unsuccessful” cases were not significantly different among the four groups.

Conclusion

No relationship was found between the ease of nasotracheal intubation using TL and glottic visualization.
