Background: Intubation in children is increasingly performed using video laryngoscopes. Many pediatric studies examine novice laryngoscopists or describe single patient experiences. This prospective randomized nonblinded equivalence trial compares intubation time for the Glide-Scope Cobalt® video laryngoscope (GCV, Verathon Medical, Bothell, WA) with direct laryngoscopy with a Miller blade (DL, Heine, Dover, NH) in anatomically normal neonates and infants. The primary hypothesis was that intubation times with GCV would be noninferior to DL. Methods: Sixty subjects presenting for elective surgery were randomly assigned to intubation using GCV or DL. Intubation time, time to best view, percentage of glottic opening score, and intubation success were documented. We defined an intubation time difference of less than 10 s as clinically insignificant. Results: There was no difference in intubation time between the groups (GCV median = 22.6 s; DL median = 21.4 s; P = 0.24). The 95% one-sided CI for mean difference between the groups was less than 8.3 s. GCV yielded faster time to best view (median = 8.1 s; DL 9.9 s; P = 0.03). Endotracheal tube passage time was longer for GCV (median = 14.3 s; DL 8.5 s; P = 0.007). The percentage of glottic opening score was improved with GCV (median 100; DL 80; P <0.0001). Conclusions: Similar intubation times and success rates were achieved in anatomically normal neonates and infants with the GCV as with DL. The GCV yielded faster time to best view and better views but longer tube passage times than DL.
