Abstract

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.
