Abstract

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.

评估使用一种新型的、用户可控制的气管插管的疗效和便利，一项试点研究

目的本研究的目的是比较气管插管中常用的预成型刚性导管与新型铰接（用户控制）导管的疗效和用户体验（UX）。方法采用NASA任务负荷指数（NASA- tlx）表格对试图通过视频喉镜对尸体进行传统和新型插管的本科生、医学生、住院医师和护理人员进行调查。结果我们发现，与传统的NASA-TLX风格相比，这种新颖的风格改善了用户体验，在体力需求、努力、时间需求和挫败感方面得分较低。传统发型在脑力方面得分较低。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。这种新型的临床前研究在使用方面显示了有希望的结果。证据水平
