Three-Dimensionally Printed Simulated Tracheas to Improve Cricothyrotomy Skills Among Anesthesia Providers

Cricothyrotomy proficiency is imperative for anesthesia providers; however, opportunities to perform this skill are infrequent making skill maintenance essential. Increased accessibility of three-dimensional (3D) printing allows for production of low-cost simulation models. The models used for simulation-based teaching and deliberate practice facilitate skill development and refinement. A cost-effective, 3D printed airway model was designed and allowed 47 anesthesia providers to complete hands-on practice during a cricothyrotomy simulation-based training program. Assessment and comparison of pre- to post- intervention was completed for self-efficacy, knowledge, time to skill completion, compliance of required steps checklist, Global Rating Scale score, and successful ventilation. Statistically significant improvement from pre- to posttest was demonstrated in: 1) self-efficacy survey scores (P < .001); 2) knowledge test scores (P < .001); and 3) decreased time (minutes:seconds) to task completion (P < .001). Time from initial posttest to 3-month posttest (P = .046) significantly increased, however, the time at 3 months posttest remained significantly lower than pretest (P < .001). Providers' ability to ventilate, compliance with procedural steps, and technical skills significantly improved. 3D printing can produce anatomically similar simulation airway models that allow providers to practice and improve cricothyrotomy knowledge and skills. Developing an affordable and accessible simulation model provides a sustainable tool that allows providers multiple cricothyrotomy practice attempts.
