Comparison of modified and conventional methods in orotracheal intubetion of GlideScope videolaryngoscope

Abstract

To compare the modified and conventional methods in orotracheal intubation of GlideScope videolaryngoscope. 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. 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. 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.
