3D Printed Model Simulator or Virtual Reality Software for Training Fiberoptic Intubation Skill

The participants in this arm will undergo two self-directed training sessions on a custom-made 3D-printed airway simulator. The participants will use a standard intubating fiberoptic bronchoscope to practice fiberoptic-assisted nasal intubation.

The sessions will be one week apart. Each session is 30 minutes per participant.

The participants in this arm will practice fiberoptic-assisted nasal intubation using the free virtual reality software (AirwayEX) on their mobile phones or computer tablets. Two practice sessions are required by the investigators. The sessions will be one week apart. Each session is 30 minutes per participant.

The participants in this arm will have the opportunity to practice on the software as often as they feel necessary. All the additional practice data will be recorded.

The 5-point rating scale assessing multiple aspects of fiberoptic intubation performance.

The assessment includes, on the scale of 1 (minimum score) to 5 (maximum score), the following;

1. Control
2. Progression
3. Orientation
4. Views and collision
5. Accuracy

The duration measured from the passing of the fiberoptic bronchoscope through the nasal opening and the time of successful intubation (defined as the passing of the endotracheal tube into the trachea above the carina).

The measured duration is reported as seconds.
