Brief Summary:

Flexible videoscope orotracheal intubation (FOI) technique is considered an important option in the management of predicted difficult airways. However, it is rarely performed in daily practice. Yet emergency physicians are expected to be able to perform this skill expertly during a crisis scenario. If it is not completed in a timely and proper fashion, the patient will deteriorate rapidly, resulting in morbidity or fatality.

There is a significant learning curve to master this complex psychomotor skill. Providing sufficient training in FOI, particularly hands-on experience in real patients is difficult. Patients with known difficult airway requiring FOI present infrequently to the emergency room. Using patients with normal airway purely for teaching of FOI is ethically controversial. To avoid technical and ethical concerns of training involving real patients, conventional teaching methods incorporate the use of a low-fidelity manikin in replacement. However, the manikin anatomy often lacks the realism of a live human.

The addition of virtual reality technology, in the form of a low-cost mobile application (Airway Ex) into the conventional simulation, may optimize learning by providing an ethical, cost-effective and more realistic modality to acquire the basic skills of FOI. If it is proven to be effective, efforts to integrate virtual reality technology into routine training of such procedures in the ED should be promoted.

We hypothesize that the addition of virtual reality mobile application to conventional training will improve procedural skill dexterity and proficiency and hence, improve learner's satisfaction and confidence in performing FOI.

Arm Intervention/treatment
Experimental: Interventional
Additional 30 minutes of self-directed learning and practice using the mobile application, after conventional training session
Other: Airway Ex App
30 minutes of self-directed learning and practice using the mobile application

No Intervention: Control
Conventional training session which includes didactic teaching and low-fidelity simulation session involving trainer's demonstration, followed by hands-on practice

Primary Outcome Measures :
  1. Time taken for successful intubation [ Time Frame: 5 minutes ]
    time from advancing scope from manikin's mouth to confirmed placement of endotracheal tube through visualisation with videoscope

Secondary Outcome Measures :
  1. Time taken for visualisation of vocal cords [ Time Frame: 1 minute ]
    time from advancing scope from manikin's mouth to first visualisation of vocal cords with videoscope

Other Outcome Measures:
  1. Quality of flexible videoscope manipulation ability [ Time Frame: 5 minutes ]
    By blinded assessor using validated Five-point Global Rating Scale of Fiberoptic Bronchoscope Manipulation Ability. Score of 1 indicates very poor techniques whereas a score of 5 indicates clearly superior techniques.
