Abstract
Background: Coronavirus disease 2019 (COVID-19) virus usually spreads through aerosol and close contact. Frontline health-care workers handle aerosol-generating procedures like endotracheal intubation. To reduce this risk, COVID-19 barrier box came into the picture. However, the COVID-19 barrier box may compromise easy and successful intubation, and their limitation must be studied.
Objectives: The objective of this study was to assess the time to successful intubation with or without the COVID-19 barrier box using the Macintosh laryngoscope and King Vision video laryngoscope (KVVL). We also assessed the first-pass success rate, ease of intubation, Cormack-Lehane (CL) grade, and requirement of external laryngeal manipulation.
Methods: We conducted this manikin-based randomized crossover study to assess the time to successful intubation by anesthesiologists (22) and emergency physicians (11) having 1 year or more experience with or without COVID-19 barrier box by using the Macintosh laryngoscope and KVVL. Our study randomized the sequence of the four different intubation scenarios.
Results: The comparison of mean duration of intubation between KVVL (13.21 ± 4.05 s) and Macintosh laryngoscope (12.89 ± 4.28 s) with COVID-19 barrier box was not statistically significant (95% confidence interval: 1.21-0.97). The ease of intubation, number of attempts, and requirement of external laryngeal manipulation were not statistically significant. Intubations were statistically significant more difficult with barrier box in view of higher CL grade.
Conclusion: Time to intubation was longer with COVID-19 barrier box using KVVL as compared to Macintosh laryngoscope which was statistically not significant.
期刊介绍:
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
