Objectives:
To evaluate whether virtual reality can function as a preparatory adjunct to hands-on cricothyrotomy simulation by supporting procedural confidence and perceived transfer of training.
Design:
Prospective, single-arm pilot evaluation.
Setting:
A live airway management workshop incorporating simulation-based training.
Participants:
Anesthesia providers.
Interventions:
Participants completed a guided virtual reality scalpel-bougie cricothyrotomy module immediately prior to performing cricothyrotomy on a physical task trainer.
Measurements And Main Results:
Primary outcomes were changes in self-reported procedural confidence and perceived transfer of training from the virtual reality module to subsequent task-trainer performance. Self-reported confidence in performing key steps of scalpel-bougie cricothyrotomy increased modestly but significantly following the virtual reality module (composite confidence score increased from 2.51 ± 1.00 to 2.89 ± 0.91; p = 0.027). Most participants reported moderate or greater perceived transfer of skills from virtual reality to the physical task trainer, despite differences in tactile feedback. Cognitive load was rated as moderate, simulator-related symptoms were uncommon, and usability ratings were generally favorable. The physical task trainer was rated superior for tactile realism, whereas virtual reality better supported procedural understanding.
Conclusions:
When integrated as a preparatory adjunct to hands-on simulation, virtual reality was associated with increased learner confidence and perceived transfer of training for cricothyrotomy. Virtual reality may support cognitive rehearsal without replacing tactile simulation.
