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.
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.
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).
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.
CricKey 是一种新型的外科环甲膜切开术器械，结合了气管钩、导丝、扩张器和通气管的功能，并与 Melker 气道套管结合在一起。本研究比较了标准开放式外科手术与 CricKey 技术的外科环甲膜切开术。
这是一项使用人体尸体模型的前瞻性交叉研究。参与者包括获得美国陆军基本急救医疗技术员认证的战斗军医。在简要的解剖复习和演示后，参与者按照随机顺序进行标准开放式外科环甲膜切开术和 CricKey 外科环甲膜切开术。主要结局是首次尝试成功，次要结局测量是手术时间。
CricKey 外科环甲膜切开术的首次尝试成功率为 100%（15/15），而开放式外科环甲膜切开术的成功率为 66%（10/15）（优势比 16.0；95%置信区间 0.8 至 326）。与开放式技术相比，CricKey 用于外科环甲膜切开术的插入速度更快（34 秒对 65 秒；中位数时间差异 28 秒；95%置信区间 16 秒至 48 秒）。
与标准的开放式外科环甲膜切开术技术相比，军事医务人员使用 CricKey 可更快地插入。两种技术的首次尝试成功率没有显著差异。
