Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Intubation time | Within 5 minutes | The time between entry of the nasotracheal tube into a nostril and appearance of a carbon dioxide wave on the monitor. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Intubation difficulty scale | During intubation | The sum of score from seven variables including intubation attempts, supplementary operators, the use of alternative techniques, glottic exposure, the lifting force applied during laryngoscopy, the necessity of applied external laryngeal pressure, and position of vocal cords. From 0 (easiest) to 8 (most difficult) |
| Epistaxis score | When removing the video-laryngoscope | grade 1 (no-epistaxis), grade 2 (mild, blood on the tube only), grade 3 (moderate, blood pooling in the pharynx), or grade 4 (severe: blood impedes intubation) |
| Numeric rating scale of intubation difficulty | During intubation | Subjective intubation difficulty from 0 (easiest) to 10 (most difficult) |
