OBJECTIVE
The purpose of this study was to compare the efficacy and user experience (UX) of a pre-formed rigid stylet commonly used in endotracheal intubations to a novel, articulating (user-controlled) stylet.
METHODS
The participants were a mixture of undergraduates, medical students, residents, and attendings who attempted to intubate cadavers using both traditional and novel stylets via video laryngoscopy, after which they were surveyed using the NASA Task Load Index (NASA-TLX) form.
RESULTS
We found the novel stylet to have improved UX, scoring lower in physical demand, effort, temporal demand, and frustration compared to the traditional stylet on the NASA-TLX. The traditional stylet scored lower on mental effort. There was no difference in how participants viewed their performance.
CONCLUSION
There was no difference in how participants viewed their performance. This preclinical study for this novel stylet showed promising results in terms of ease of use.
LEVEL OF EVIDENCE
目的
本研究旨在比较气管插管中常用的预制刚性管芯与新型可弯曲（用户控制）管芯的有效性和用户体验（UX）。
方法
参与者包括本科生、医学生、住院医师和主治医师，他们通过视频喉镜使用传统和新型管芯尝试对尸体进行插管，之后使用美国国家航空航天局任务负荷指数（NASA-TLX）表格对他们进行调查。
结果
我们发现新型管芯的用户体验有所改善，在NASA-TLX上，与传统管芯相比，其在体力需求、努力程度、时间需求和挫败感方面得分更低。传统管芯在脑力努力方面得分更低。参与者对自己表现的看法没有差异。
结论
参与者对自己表现的看法没有差异。这项针对新型管芯的临床前研究在易用性方面显示出了有前景的结果。
