Objectives: The aim of the current study was to
compare intraocular pressure (IOP), hemodynamic parameters and throat pain in
the use of C-MAC videolaryngoscope and the Macintosh laryngoscope under general
anesthesia requiring endotracheal intubation.

Methods: Seventy-eight
patients aged 18-65 years, ASA (American Society of
Anesthesiologists physical status). I-II, who underwent
elective surgery under general anesthesia were scheduled in the study. The groups were allocated as
Group M (Macintosh laryngoscope) and Group VL (videolaryngoscope). Standard
anesthesia technique was used in both groups. To assess the depth of
anesthesia which was kept between 40 and 60, a Bispectral Index Monitor Model
2000 (Aspect Medical Systems, Inc, Newton, MA) was used throughout the study. We
recorded hemodynamic variables, oxygen saturation before induction, at the 3rd
and at the 10th minutes after intubation. The duration of intubation was
recorded as the time from the laryngoscope entering the mouth to removal with
end-tidal carbon dioxide on the monitor. IOP was measured before
induction, and at the 3rd and 10th minutes after intubation. Inhalation agent
was given after intubation. 78 patients were included in the study. We
recorded cough after extubation, and postoperative sore throat was evaluated by
an anesthesiologist who was blinded to the group allocations at 10 minutes and
at 24 hours postoperatively.

Results: There was no significant difference
between the groups regarding age (p >
0.05), mean body mass index (p = 0.157),
mean ASA (p = 0.475), mean bispectral
index values (p
= 0.084)
and mean operating time (p = 0.068).
The mean duration of intubation was determined to be statistically
significantly longer in Group M than in Group VL (p = 0.0001). There was no statistically significant difference
between the groups regarding Modified Mallampati Score (p = 0.571) and Cormack Lehane Score (p = 0.819). The mean IOP at 3rd minute after intubation was
determined to be statistically significantly higher in Group M (p = 0.0001). There was no statistically
significant difference between the groups in regarding cough after extubation (p = 0.549), throat pain at 10 minutes (p = 0.662) and at 24 hours
postoperatively.

Conclusions: C-MAC videolaryngoscope can be
recommended as the first choice in patients with high IOP requiring general
anesthesia with endotracheal intubation.
