Abstract

Purpose: A previous study reported a shorter time to tracheal intubation by reducing percentage of glottic opening (POGO) view to <50% when intubating a normal adult airway using the Glidescope^TM blade. We evaluate the efficacy of reducing POGO to <50% when intubating patients with rigid cervical immobilization using CMAC^TM D blade.

Methods: One hundred and four adult patients were randomized to group POGO 100% or POGO <50% . Laryngoscopy was performed by advancing tip of the D blade at vallecula. POGO 100% was achieved by exerting upward force to displace epiglottis until glottic opening from the anterior commissure to inter arytenoid notch. POGO < 50% was acquired by withdrawing the D blade tip dorsally from vallecula. The primary outcome was time to intubation.

Results: The median time (IQR) to successful intubation was 29 (25-35) seconds for group POGO < 50% and 34 (28-40) seconds for group with POGO 100% (difference in medians, 5 seconds; 95% confidence interval, 2 to 8, p = 0.003). Complications were minor.

Conclusion: Using the CMAC^TM D blade with a reduced POGO in patients with cervical spine immobilization resulted in faster tracheal intubation.

Trial registration: The trial is registered at ClinicalTrial.gov (CT.gov identifier: NCT04833166).

CMACTM - D叶片气管插管对模拟颈椎损伤的部分声门观察与全声门观察:一项随机对照试验。

目的:先前的一项研究报道了通过减少声门开口(POGO)视野到TM刀片的百分比来缩短气管插管时间。我们评估了将POGO还原为TM D刀片的疗效。结果:POGO < 50%组插管成功的中位时间(IQR)为29(25-35)秒，POGO 100%组插管成功的中位时间(IQR)为34(28-40)秒(中位差异为5秒;95%置信区间，2 ~ 8,p = 0.003)。并发症很少。结论:颈椎固定患者使用CMACTM - D刀片降低POGO可加快气管插管速度。试验注册:该试验在ClinicalTrial.gov (CT.gov标识符:NCT04833166)上注册。

期刊介绍： The journal serves the device research community by providing a comprehensive body of high-quality information from leading experts, all subject to rigorous peer review. The Expert Review format is specially structured to optimize the value of the information to reader. Comprehensive coverage by each author in a key area of research or clinical practice is augmented by the following sections: Expert commentary - a personal view on the most effective or promising strategies Five-year view - a clear perspective of future prospects within a realistic timescale Key issues - an executive summary cutting to the author''s most critical points In addition to the Review program, each issue also features Medical Device Profiles - objective assessments of specific devices in development or clinical use to help inform clinical practice. There are also Perspectives - overviews highlighting areas of current debate and controversy, together with reports from the conference scene and invited Editorials.
