Comparison of the HugeMed video laryngoscope with the Macintosh direct laryngoscope for nasotracheal tracheal intubation in children undergoing dental treatment: a randomized controlled clinical study

ABSTRACT

Objectives

The aim of this study was to compare the performance of the HugeMed® videolaryngoscope with a direct Macintosh laryngoscope for nasotracheal intubation.

Methods

Eighty-eight children aged 4–10 years were randomly assigned to either the HugeMed® videolaryngoscope (HVL) or the Macintosh direct laryngoscope (MDL) group. Intubation difficulty, glottic view grade, time-to-intubation, number of tracheal intubation attempts, use of external laryngeal manipulation and Magill forceps, recovery time, pediatric-anesthesia-delirium-scale (PAEDS) scores, pain due to tracheal intubation, and laryngeal bleeding were evaluated.

Results

Easy tracheal intubation incidence was higher in the HVL group than that in the MDL group (p = 0.001). Glottic view was better in the HVL group as compared to the MDL group (p = 0.027). There was no difference between the groups in terms of time-to-tracheal intubation, number of tracheal intubation attempts, Magill forceps usage, pain, and bleeding due to tracheal intubation. The need for external laryngeal manipulation (p = 0.004) and PAEDS scores (p = 0.006) were higher in the MDL group than those in the HVL group.

Conclusion

HugeMed® videolaryngoscope may provide easier tracheal intubation, create a better glottic view, and significantly reduce the need for additional manipulation compared to the Macintosh direct laryngoscope, for nasotracheal intubation.
