[Comparison of hemodynamic responses to orotracheal intubation between using GlideScope videolaryngoscope and fiberoptic bronchoscope].
OBJECTIVE
To compare the hemodynamic responses to orotracheal intubation with GlideScope videolaryngoscope (GSVL) and with fiberoptic bronchoscope (FOB) after induction of general anesthesia.


METHODS
Totally 57 ASA physical status I - II adult patients undergoing elective plastic surgery and requiring orotracheal intubation were randomly allocated to either GSVL group (n = 29) or FOB group (n = 28). After a routine intravenous anesthetic induction, orotracheal intubation was performed. Noninvasive blood pressure (BP) and heart rate (HR) were recorded before and after anesthetic induction, at intubation and thereafter at 1 minute interval for 5 minutes.


RESULTS
The intubation time was not significantly different between the two groups (P > 0.05). After intubation, BP and HR exhibited significant increases compared to the post-induction values in both groups, but the maximum values of BP did not exceed the pre-induction values while the maximum value of HR was higher than the pre-induction value. During the observation, BP and HR at all time points as well as the maximum values of BP and HR had no significant differences between the two groups (P > 0.05).


CONCLUSIONS
The orotracheal intubations using FOB and GSVL result in similar hemodynamic responses.
