Abstract

BACKGROUND
Optiscope(TM) is a newly developed video stylet device. This study evaluated and compared the hemodynamic changes observed after endotracheal intubation with video stylet and after conventional laryngoscopic endotracheal intubation.
METHODS
Fifty-eight adult patients with American Society of Anesthesiologists (ASA) physical status class 1 or 2, undergoing general anesthesia, were randomized into two groups: one group of patients were intubated using video stylet (n = 29) and the other group were intubated using direct laryngoscope (n = 29). Systolic blood pressure (SBP), mean arterial pressure (MAP), diastolic blood pressure (DBP), heart rate (HR), POGO (percentage of glottic opening) score, time for intubation and degree of sore throat were recorded.
RESULTS
There were no significant differences in the SBP, MAP, DBP, HR, and the sore throat incidence between the two groups. Optiscope(TM) produced better POGO scores, but time for intubation was longer than with conventional laryngoscope.
CONCLUSIONS
Optiscope(TM), when compared with conventional laryngoscope for intubation, does not modify the hemodynamic response, but it provides a better view of the vocal cords.
