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

Study Overview
=================
Brief Summary
-----------------
Fiberoptic-assisted intubation is an advanced skill that requires learners' practice as well as clinical experience during the anesthesiology residency training period. Current training methods including airway simulators and virtual reality software are used by medical schools worldwide. The objective of this study is to compare the learner's fiberoptic intubation performance between training with a 3D-printed simulator and a virtual reality software.

Detailed Description
-----------------
Fiberoptic-assisted intubation (FOI) is an essential skill of an anesthesiologist. It requires comprehensive knowledge of the airway anatomy and the proper and skillful use of a fiberoptic bronchoscope. Fiberoptic-assisted intubations are usually performed in emergency situations and during difficult airway patient encounters. These situations are not ideal for learners to properly practice the skill. The process of acquiring FOI skills includes teaching by experienced instructors, self-practice using commercially-available airway simulators, and practicing on virtual reality software. The airway simulators and virtual reality software have their advantages and disadvantages. In this randomized study, the investigators will compare the fiberoptic intubation skill among anesthesiology residents after self-training on a custom-made 3D simulator and self-training on a virtual reality software.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: 3D printed simulator<br>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. | Other: 3D-printed airway simulator<br>* Two self-directed training on a standard fiberoptic bronchoscope and a custom-made 3D airway simulator.<br>|
| Experimental: Virtual reality software<br>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. | Other: virtual reality software, AirwayEx<br>* Two self-directed training on AirwayEx. With additional training as necessary.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Global rating scale score for fiberoptic intubation performance (GRS scale) | 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; Control Progression Orientation Views and collision Accuracy | 1 week after self-directed practice session | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Time to successful intubation | 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. | 1 week after self-directed practice session |
