Title: NoL Index, Heart Rate and Mean Arterial Blood Pressure Responses to Tracheal Intubation Performed With MacIntosh Blade Versus Glidescope
Brief Summary: Prospective, randomized and controlled who will be conducted in Maisonneuve-Rosemont hospital and whose objectives are:

* To observe if the alterations of the NoL index and the standard monitoring (Mean Arterial Blood Pressure and Heart Rate) (using the variability of NoL index and standard monitoring, peak NoL index and peak standard monitoring values, and number of time passed over their respective threshold for nociceptive response) are more accentuated after laryngoscopy using the classical MAC blade versus single-use disposable blade of the Glidescope.
* To observe the nociceptive response (using the variability of NoL index and standard monitoring, peak NoL index and peak standard monitoring values, and number of time passed over their respective threshold for nociceptive response) related to the insertion of endotracheal tube between vocal cords during the intubation.

Study plans to enroll 50 adult patients scheduled to undergo either general, gynecological, neurological, orthopedic, plastic or urological surgery under general anesthesia and who necessitate endotracheal intubation.
