Abstract
Objective: Cricothyrotomy is rarely performed by prehospital providers. Developing this low-frequency, high-acuity skill and maintaining competence is difficult; thus, using a realistic training model is paramount to successful training. The aim of this study was to evaluate a 3-dimensional-printed bleeding cricothyrotomy trainer in increasing paramedic comfort level and procedural competence as defined by completing the procedure unassisted without error.
Methods: Model implementation took place during mandatory biannual difficult airway training courses for all paramedics employed by a hospital-based ambulance agency. Participating paramedics performed 3 surgical cricothyrotomies using the bleeding trainer and subsequently completed an anonymous written survey that evaluated the comfort level of providers in performing a surgical cricothyrotomy both before and after training using a 10-point visual analog scale.
Results: Forty-four paramedics participated in the difficult airway training course. All (44/44) completed the postsurvey. Participants noted that their procedural skill comfort level improved after the training took place (average improvement of 3 ± 1.93). Participants also indicated that the high-fidelity trainer played a significant role in their increased comfort after skills training.
Conclusion: The bleeding cricothyrotomy model evaluated provides a high-fidelity, cost-effective means of teaching and maintaining a rare, lifesaving skill that is rarely performed in the field.
