Abstract

Study objective The CricKey is a novel surgical cricothyroidotomy device combining the functions of a tracheal hook, stylet, dilator, and bougie incorporated with a Melker airway cannula. This study compares surgical cricothyroidotomy with standard open surgical versus CricKey technique. Methods This was a prospective crossover study using human cadaveric models. Participants included US Army combat medics credentialed at the emergency medical technician-basic level. After a brief anatomy review and demonstration, participants performed in random order standard open surgical cricothyroidotomy and CricKey surgical cricothyroidotomy. The primary outcome was first-pass success, and the secondary outcome measure was procedural time. Results First-attempt success was 100% (15/15) for CricKey surgical cricothyroidotomy and 66% (10/15) for open surgical cricothyroidotomy (odds ratio 16.0; 95% confidence interval 0.8 to 326). Surgical cricothyroidotomy insertion was faster for CricKey than open technique (34 versus 65 seconds; median time difference 28 seconds; 95% confidence interval 16 to 48 seconds). Conclusion Compared with the standard open surgical cricothyroidotomy technique, military medics demonstrated faster insertion with the CricKey. First-pass success was not significantly different between the techniques.
