Abstract:
ABSTRACT
Background and aims
Direct laryngoscopy necessitates the alignment of the oropharyngeal-laryngeal axis. This
study aimed to compare direct laryngoscopy with a Macintosh blade to King-Vision Video
laryngoscope for tracheal intubation in patients with non-difficult airways who were
scheduled for elective operations under general anaesthesia.
Methods
In this prospective randomised clinical trial,118 adults with ASA I and II requiring
endotracheal intubation for surgeries under general anaesthesia, were enrolled and
randomised into either of the two groups(Group DL-direct laryngoscope and Group VL-video
laryngoscope), where they were intubated using King Vision or direct laryngoscope with
Macintosh blade. The Primary objective was to compare time to intubate, Visualization of the
laryngeal view by Cormack-Lehane grade and Successful first attempt. Secondary objective
were to record the number of intubation failure, number of attempts, change of anaesthetist
and use of adjunct equipment and the complications such as oropharyngeal trauma, neck
pain, dysphagia, hoarseness.
