Comparison of the UEscope Video Laryngoscope with the Traditional Direct Laryngoscope in Neonates and Infants: A Randomized Clinical Trial

Many tools are used to predict difficult airway, including bedside screening tests, radiological variables, and ultrasonography. However, the “gold standard” to identify difficult airway before intubation has not been established. The assessment and prediction of difficult airway is receiving increasing attention in clinical practice due to the devastating results of failed oxygenation or intubation. A literature visualization study is necessary to understand the research trend and help tailor future research directions. Science citation index-expanded web of Science database were used to search for literature related to assessment and prediction of difficult airways published before May 9th, 2022. VOS viewer software was used for visual analysis, including literature statistics, and co-occurrence analysis. A total of 2609 articles were included. The amount of relevant research interest and literature is increasing every year. According to co-occurrence network analysis, the research results can be grouped into the following 5 clusters, intubation approaches, intubation in special populations, difficult airway assessment tests, intubation in critical care/emergency settings and education, and laryngoscopes. Co-occurrence overlay analysis showed that video laryngoscopes and index prediction (including computed tomography and ultrasonography), emerged recently and comprised an important percentage of current studies. It can be predicted that future studies should focus on understanding the upper airway anatomy and constructing risk index predictions. Based on current global research trends, risk index predictions are the next hot topics in the evaluation and prediction of difficult airways, and video laryngoscopes will continue to be a hot topic in this field.

We aimed to analyze the effect of video laryngoscopy on intubation success, time to intubation, and adverse events in infants and neonates. A systematic review and meta-analysis was performed, for which a neonates (age less than 29 days) and infants (age less than 365 days) needing to be intubated were included. The main outcomes were first attempt success rate in the intubation, time to intubation, and adverse events. Evidence certainty was assessed according to GRADE. We included 13 studies. Seven studies with 897 patients focused on neonates, and the first attempt success rate was higher in the video laryngoscopy group (RR 1.18, CI: 1.03–1.36). Six studies included 1039 infants, and the success rate was higher in the video laryngoscopy group (RR 1.06, CI: 1.00–1.20). Time to intubation was assessed in 11 trials, and there was no difference between the groups (mean difference 1.2 s, CI − 2.2 s to + 4.6 s). Odds of desaturation (OR 0.62, CI 0.42–0.93) and nasal/oral trauma (OR 0.24, CI 0.07–0.85) were lower in the video laryngoscopy group. Evidence certainties varied between moderate and low.Conclusion: We found moderate certainty evidence that the use of video laryngoscopy improves first attempt success rates in neonate and infant intubations, while the time to intubation did not differ between video and direct laryngoscopy groups. Further studies are still needed to improve the first intubation success rates in neonates. What is known:• Video laryngoscopy has been shown to improve first-pass intubation success rates and reduce time to intubation in adults and older children.What is new:• Video laryngoscopy improved the first attempt intubation success rates both in neonates and in infants.• Video laryngoscopy did not increase the time to intubation, and it was associated with less adverse events than direct laryngoscopy.
