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

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.
