The purpose of this study is to assess and compare conditions for tracheal intubation obtained with modified time principal induction with 0.6 mg/kg rocuronium and 1 mg/kg succinylcholine. Specifically, the investigators will be evaluating ease of laryngoscopy, vocal cord view, vocal cord opening, and movement of limbs and coughing during tracheal intubation in order to assess intubation conditions, to compare efficiency and success rate of tracheal intubation between two induction agents and to determine the rate of patient awareness during induction and post-operative recall of paralysis.

| Modified Time Principle Induction (MTPI) with rocuronium | Drug | Participants will be induced using lidocaine 1 mg/kg IV, an opioid such a fentanyl (1-2 mcg/kg) IV, followed by 0.6 mg/kg IV rocuronium, and IV propofol with dosage at the discretion of the care team, administered within 10 seconds of rocuronium and the intubation will be performed with a C-MAC |
| Measure | Description | Time Frame |
|---|---|---|
| Ease of laryngoscopy | Ease of laryngoscopy is scored categorically as easy (Jaw relaxed, no resistance to blade during laryngoscopy) , fair (Jaw not fully relaxed, some resistance to blade) or difficult (Poor jaw relaxation, active resistance by patient to laryngoscopy) | During procedure (Between laryngoscope insertion to onset of ventilation (less than 7 minutes)) |
| Position of vocal cords | Position of vocal cords is scored categorically as abducted, intermediate or closed | During procedure (Between laryngoscope insertion to onset of ventilation (less than 7 minutes)) |
| Movement of vocal cords | Movement of vocal cords is scored categorically as none , moving or closing | During procedure (Between laryngoscope insertion to onset of ventilation (less than 7 minutes)) |
| Number of participants who moved their limbs during intubation | none, slight or vigorous | During procedure (Between laryngoscope insertion to onset of ventilation (less than 7 minutes)) |
| number of participants who coughed during tracheal intubation | none, diaphragm or sustained (>10s) | During procedure (Between laryngoscope insertion to onset of ventilation (less than 7 minutes)) |
| Measure | Description | Time Frame |
|---|---|---|
| Number of participants for whom tracheal intubations were successful on the first attempt | 5 minutes after intubation and successful ventilation | |
| Number of times tracheal intubations are attempted | 5 minutes after intubation and successful ventilation |
