Abstract
The relative effectiveness of GlideScope(®) videolaryngoscopy (GV) for nasotracheal intubation in pediatric patients is unclear. The purpose of this study is to evaluate the usefulness of GV for nasotracheal intubation compared with direct laryngoscopy (DL) in pediatric patients. Our patient cohort consisted of 80 children <10 years of age who required nasotracheal intubation for elective dental or facial surgery. The patients were randomly allocated to GV (n = 40) or DL (n = 40) group. The time to intubation (TTI), glottic view grade, frequency of Magill forceps use, and degree of difficulty in intubation were evaluated. The median TTI was similar between the groups. The TTI of the former 20 patients was faster in the DL group (53.3 s, interquartile range: 42.0-64.3) than GV group (65.9 s, interquartile range: 56.0-93.9) (P = 0.007), whereas the TTI of the latter 20 patients was comparable between the groups. There were no significant differences in glottic view grade, frequency of Magill forceps use, and degree of difficulty in intubation between the two groups. GV can provide similar intubation performance characteristics compared with DL when used for nasotracheal intubation in pediatric patients. However, experience is needed to be skillful in the GV to acquire comparable TTI with DL.
