Brief summary
The purpose of this study is to evaluate if intubation with video laryngoscopy (VL) will result in less head motion and therefore less cervical motion when compared with direct laryngoscopy (DL). The aim of the study is to determine the amount of head motion (extension, flexion and rotation) when using Storz C-Mac® video laryngoscopes and direct laryngoscopes. Secondarily, the study will also measure the number of attempts to properly intubate and the time required for intubation with either technique.
Detailed description
Investigator initiated single site prospective and randomized controlled trial.
Interventions
Head motion will be measured by using Polhemus Patriot™ electromagnetic tracking system
Time for intubation will be measured from the laryngoscope entering the mouth to the endotracheal tube passing through the vocal cords

Eligibility
Inclusion criteria
* patients being orally intubated in the Operating Room as per standard anesthesia procedures
Exclusion criteria
* previous history of cervical spine injury or surgery * craniofacial abnormalities * airway congenital abnormalities * airway prior to surgery
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Head Motion - Extension or Flexion | During the process of intubation (less than one minute) | Head motion will only be measured while the patient is being endotracheally intubated. Usually this takes less than one minute. No follow up after that. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Time for Intubation | During the process of intubation (less than one minute) | Time from when the laryngoscope blade enters the mouth until the endotracheal tube enters the vocal cords. No follow up after that. |

Outcome results
Head Motion - Extension or Flexion
Head motion will only be measured while the patient is being endotracheally intubated. Usually this takes less than one minute. No follow up after that.
Time frame: During the process of intubation (less than one minute)
| Arm | Measure | Value (MEAN) | Dispersion |
|---|---|---|---|
| Video Laryngoscopy | Head Motion - Extension or Flexion | 16.5 degrees of extension | Standard Deviation 9.5 |
| Direct Laryngoscopy | Head Motion - Extension or Flexion | 17.7 degrees of extension | Standard Deviation 11.1 |
Time for Intubation
Time from when the laryngoscope blade enters the mouth until the endotracheal tube enters the vocal cords. No follow up after that.
Time frame: During the process of intubation (less than one minute)
| Arm | Measure | Value (MEAN) | Dispersion |
|---|---|---|---|
| Video Laryngoscopy | Time for Intubation | 25.8 second | Standard Deviation 18.4 |
| Direct Laryngoscopy | Time for Intubation | 18.9 second | Standard Deviation 10.8 |
