: Neonatal intubation is a complex procedure, often associated with low first-pass success rates and a high incidence of complications. Video laryngoscopes provide several advantages, including higher success rates, especially for novice clinicians, a magnified airway view that can be shared with supervisors, and the ability to record still or video images for debriefing and education. However, video laryngoscope devices vary, raising the possibility of differences in usability. : The study used mixed methodology, including observations, semi-structured interviews, think-aloud techniques, high-fidelity simulations, function tests, and questionnaires to assess usability, defined by the clinician satisfaction, efficacy, and efficiency of six video laryngoscope devices; (1) C-MAC with Miller blade, (2) GlideScope Core with Miller blade, (3) GlideScope Core with hyperangle LoPro blade, (4) Koala Vision Ultra with Miller blade, (5) Koala Handheld with Miller blade, and (6) Parker Neonatal with Miller blade. Clinician satisfaction was determined by the System Usability Scale (SUS), National Aeronautics and Space Administration Task Load Index (NASA-TLX), and clinician preference. Device efficacy was determined by first-pass success, number of attempts, and overall success. Efficiency was assessed by time to successful intubation and function test completion rates. : Neonatal video laryngoscopes varied considerably in design, impacting usability. All devices were deemed suitable for neonatal intubation, with the Koala Handheld, C-MAC, and GlideScope Core Miller demonstrating the highest usability. : This simulation-based study highlights substantial variability in neonatal video laryngoscope usability, indicating the need for further research into usability in the clinical setting.
新生儿插管是一个复杂的操作过程，通常首次成功率较低且并发症发生率较高。视频喉镜具有多个优点，包括更高的成功率，尤其是对新手临床医生而言；可放大的气道视野，能与上级医生共享；以及能够记录静态或视频图像用于病例汇报和教学。然而，视频喉镜设备各不相同，这增加了可用性存在差异的可能性。
该研究采用了混合方法，包括观察、半结构化访谈、出声思考技术、高保真模拟、功能测试和问卷调查，以评估六种视频喉镜设备的可用性，可用性由临床医生满意度、有效性和效率来定义；这六种设备分别是：(1) 带米勒刀片的C-MAC；(2) 带米勒刀片的GlideScope Core；(3) 带超广角低轮廓刀片的GlideScope Core；(4) 带米勒刀片的考拉视觉超型；(5) 带米勒刀片的考拉手持式；(6) 带米勒刀片的帕克新生儿型。临床医生满意度由系统可用性量表（SUS）、美国国家航空航天局任务负荷指数（NASA-TLX）以及临床医生偏好来确定。设备有效性由首次成功率、尝试次数和总体成功率来确定。效率通过成功插管时间和功能测试完成率来评估。
新生儿视频喉镜在设计上差异很大，影响了可用性。所有设备都被认为适用于新生儿插管，其中考拉手持式、C-MAC和GlideScope Core米勒型表现出最高的可用性。
这项基于模拟的研究突出了新生儿视频喉镜可用性的显著差异，表明需要在临床环境中对可用性进行进一步研究。
