[Comparison of modified and conventional methods in orotracheal intubetion of GlideScope videolaryngoscope].

Objective: To compare the modified and conventional methods in orotracheal intubation of GlideScope videolaryngoscope.
Methods: Sixty patients aged 21-53 years with ASA physical status I-II were scheduled for elective abdominal operation under general anesthesia. After routine anesthesia induction orotracheal intubation was performed with GlideScope videolaryngoscope; the patients were randomly divided into two groups (n=30 in each): Group M received modified orotracheal intubation and Group C received conventional orotracheal intubation. Noninvasive blood pressure and heart rate were recorded before and after anesthesia induction, at intubation, 1 and 3 min after intubation.
Results: The time of intubation procedure was significantly longer in Group C than in Group M. BP and HR significantly decreased after intubation, there were no differences between two groups.
Conclusion: The modified method can improve the readiness of the procedure but it shows no advantages in prevention of adverse hemodynamic responses during the orotracheal intubetion of videolaryngoscopy.
