[GlideScope Cobalt: assessment of performance in 50 children].

Background: GlideScope Cobalt video laryngoscope is a new type of GlideScope series. A reusable camera baton is inserted into a disposable plastic curved blade. The blade has 5 choices of size and can be used from infants to adults. The aim of the current study was to evaluate the efficacy of GlideScope Cobalt in children.

Methods: Endotracheal intubation was performed in 50 surgical children undergoing general anesthesia. The length of time in intubation, percentage of glottic opening (POGO) score and optimizing procedures were recorded.

Results: 100% POGO score was obtained in 42 cases. Successful endotracheal intubation was performed in 47 cases and 37 patients were intubated within 1 minute. It took over 1 minute to intubate in 13 cases, because of the difficulty of tracheal tube maneuver. Particular children, mostly aged 6-8, had difficulty in matching the size of the blade because of the large difference between the sizes of blade 2 and that of blade 3.

Conclusions: GlideScope Cobalt is a useful tool in chidlren's airway management but it necessitates getting used to the tracheal tube maneuver and lacks the suitable blade size for 6-8 years old children.
