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.


Options:
A: Inclusion Criteria:

The patients who will undergo general anesthesia for abdominal surgery, American Society of Anesthesiologists physical status I to III, The patients who were aged between 20 and 75

Exclusion Criteria:

Our exclusion criteria were to have a history of emergency intubation or a difficult intubation, to have a body mass index higher than 35 or a rheumatologic disease that cause limitation of cervical motion, to have a previous history of cervical operation or tumor, trauma or infection on upper airway, and to have no tooth.
B: Inclusion Criteria:

* Patients requiring emergency Rapid Sequence Intubation at the emergency department
* Male and Female subjects 18 years to 99 years of age
* Written confirmation by a physician not involved in this study
* Written informed consent by the participant (obtained afterwards)
* Patient not showing remarkable rejection in participation in this study

Exclusion Criteria:

* Maxilla-Facial trauma
* Immobilized cervical spine
* Indication for fiberoptic guided intubation (known difficult airway)
* Ongoing Cardio-Pulmonary-Resuscitation (CPR)
* Involvement in any other clinical trial during the course of this trial, within a period of 30 days prior to its beginning or 30 days after its completion
* Severe or immediately life-treating injury requiring immediate medical treatment
C: Inclusion Criteria:

* Adult patients (age \>17) requiring emergent endotracheal intubation in the Emergency Department using direct laryngoscopy

Exclusion Criteria:

* Physician intends to intubate with a device other than a direct laryngoscope
D: Inclusion Criteria:

* ASA status I or II
* Mallampati class I or II
* Patients \> 18 years old
* Elective general, gynecological, neurological, orthopedic, plastic or urological surgery under general anesthesia
* Type of surgery that usually necessitate endotracheal intubation and controlled ventilation

Non-inlusion Criteria:

* Patient refusal
* History of psychiatric diseases or psychological problems (including mental retardation); inability to give consent; language barrier.
* Anticipated difficult airway (Mallampati class III and IV, thyromental distance \< 6 cm, mouth opening \< 3 cm, neck extension \<80° and neck flexion \<35°, inability to prognath, meaning bringing lower mandibular before the upper maxilla)
* Patient with history of neck rigidity or instability
* BMI \> 30
* Patient with beard (because of recognized risk for difficult ventilation)
* Patient with history of oropharyngeal or tracheal surgery (excluding adenoidectomy, amygdalectomy and teeth removal)
* Severe coronary artery disease
* Serious cardiac arrhythmias (including atrial fibrillation)
* Use of β-blockers (all types)
* History of opioid or illicit drug substance abuse
* Chronic use of psychotropic and/or opioid drugs
* Allergy to remifentanil or propofol
* Pregnancy
* Contraindications to mask ventilation (GI tract obstruction, pregnancy, active GERD, non-fasting patients)
* Difficult mask ventilation (before randomization at the first laryngoscopy)

Exclusion Criteria:

* Unexpected difficult airway requesting excessive, possibly painful airway manipulations
* Requiring hemodynamic support with vasopressors or inotropes 5 minutes before first laryngoscopy to 3 minutes after insertion of ETT
