Study type
Interventional
Description of intervention(s) / exposure
Arm 1: tracheal intubation using the SensaScope.
Arm 2: tracheal intubation suing the Bonfils retromolar scope.
After anesthesia induction, the anesthesiologist will use either the SensaScope or Bonfils Retromolar scope (based on randomization) to intubate the patient under direct vision. Tracheal intubation should be achieved within one minute. If not, the procedure is aborted and the patient is manually ventilated for 15 seconds, then a second attempt is made with the same device. After 3 unsuccessful attempts at intubation, the patient will be deemed difficult to intubate and the standard algorithm for difficult intubation will be followed.

Comparator / control treatment
Arm 3: tracheal intubation using a conventional laryngoscope.
After anesthesia induction, the anesthesiologist will use the conventional laryngoscope (based on randomization) to intubate the patient under direct vision. Tracheal intubation should be achieved within one minute. If not, the procedure is aborted and the patient is manually ventilated for 15 seconds, then a second attempt is made with the same device. After 3 unsuccessful attempts at intubation, the patient will be deemed difficult to intubate and the standard algorithm for difficult intubation will be followed.

Outcomes
Primary outcome [1] 269207 0
Time to successful tracheal intubation will be measured using a stop watch. The start time is when the airway device is inserted into the oral cavity and the finish time is when the airway device is removed from the oral cavity
Timepoint [1] 269207 0
at the end of successful tracheal intubation, the total time required for intubation will be recoreded.
Primary outcome [2] 269208 0
Cardiac output changes in response to tracheal intubation will measured non-invasively using the Nexfin (Registered Trademark) monitor which will be applied prior to inductino of anesthesia.
Timepoint [2] 269208 0
At Baseline, on induction of anesthesia and every minute thereafter until 3 minutes after successful tracheal intubation
Primary outcome [3] 269209 0
Hemodynamic response to tracheal intubation will be determined by measuring systolic, diastolic, and mean blood pressure together with heart rate using the Nexfin (Registered Trademark) monitor.
Timepoint [3] 269209 0
At Baseline, on induction of anesthesia and every minute thereafter until 3 minutes after successful tracheal intubation
Secondary outcome [1] 279125 0
Number of attempts at tracheal intubation
Timepoint [1] 279125 0
at the end of successful tracheal intubation

Summary
Brief summary
This study is designed to determine the stress response to tracheal intubation using a non-invasive device that measures blood flow from the heart, blood pressure, and heart rate. In addition, it will determine the time required for tracheal intubation using two special airway devices and compare it with the time required using a conventional airway device. These special devices are used for difficult intubation cases but we will use them in patients with expected easy intubation in this study.
