BACKGROUND
Video laryngoscope is an important tool for orotracheal intubation in anaesthesia
practice particularly in difficult airways. It provides an indirect view of glottis
without the need of alignment of oropharyngeal-laryngeal axis. We compared the
intubation characteristics of channelled versus non-channelled blades of King
VisionTM Video Laryngoscope.
METHODS
In this study 60 patients were randomly allocated to two groups; group C were
intubated with channelled and group NC with non-channelled blade of King Vision.
We measured time for glottis visualisation and intubation time using both blades.
Percentage of glottis opening (POGO), insertion attempts, intubation attempts,
and ease of intubation were also assessed.
RESULTS
The time for glottis visualisation was 8.5 ± 3 seconds for group C and 7 ± 2
seconds for group NC. Intubation time was 24 ± 8.5 seconds for group C and 44
± 5 seconds for NC. There was no statistical difference in POGO, insertion
attempts, intubation attempts and ease of intubation between the two groups.
CONCLUSIONS
We concluded that the time for glottis recognition is longer but intubation time is
shorter when using King Vision video laryngoscope channelled blade as compared
to non-channelled blade.
