ABSTRACT
Introduction:
Maintaining control over the airway is critical during general anesthesia
induction, particularly in patients with anticipated difficult airways. Video laryngoscopy
with various devices has emerged as a valuable tool in such scenarios and has shown
promising performance. This study aimed to evaluate glottic visualization and the first
attempt success rate of tracheal intubation of GlideScope and Sanyar video laryngo-
scopes in adult patients with predicted difficult intubation.
Material and methods:
A randomized, controlled, two-armed, parallel clinical trial was conducted,
in adult patients with anticipated difficult intubation undergoing elective surgery under general anesthesia. Participants were randomly assigned to either the GlideScope
or Sanyar group. The primary outcome was the success rate of intubation in the first
attempt at laryngoscopy, and secondary outcomes were the duration of intubation,
glottic visualization, blood pressure and heart rate after intubation.
Results:
A total of 93 patients were included in the analysis, with 46 in the S group and
47 in the G group. The S group demonstrated a significantly higher first-attempt success rate of tracheal intubation (93.4% vs. 85.2%; P = 0.002) and shorter intubation time
(29.28 ± 8.00 seconds vs. 42.73 ± 15.50 seconds; P = 0.0001) compared to the G group.
Glottic visualization and hemodynamic changes did not significantly differ between
the two groups.
Conclusions:
The Sanyar video laryngoscope exhibited superior efficacy in terms of
first-attempt tracheal intubation success and shorter intubation time compared to
the GlideScope in adult patients with predicted difficult airways. These findings suggest
that the Sanyar video laryngoscope may serve as a valuable alternative in challenging
intubation scenarios.
