Global research trends in prediction of difficult airways: A bibliometric and visualization study

Abstract

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.

A new score for airway assessment using clinical and ultrasound parameters

“…Besides, a strong trend between male gender and DL ( p = 0.0508) has been observed. This finding has also been described in other studies ( 19 , 21 , 25 , 27 , 32 , 33 ). On the other hand, some authors ( 22 – 24 , 34 , 35 ) could not find a statistically significant correlation.…”

Dinamika Agenda Setting dan Formulasi Kebijakan untuk Pembangunan Berkelanjutan: Analisis Bibliometrik

“…yang dihasilkan. Ini memungkinkan pemahaman yang lebih baik tentang konteks dan signifikansi dari hubungan antaristilah dalam kluster-kluster tersebut (Chandra, 2018) dan (Li et al, 2023). Misalnya, overlay visualization dapat mencakup bidang penelitian utama yang diwakili oleh setiap kluster, seperti Klaster 1 yang menitikberatkan pada adopsi praktik bisnis berkelanjutan dan studi kasus.…”

“…Selain itu, overlay visualization juga memperhitungkan relevansi masing-masing istilah atau konsep dalam kluster terhadap isu-isu global atau regional tertentu, seperti Klaster 3 yang menyoroti perubahan iklim dan komitmen terhadap pembangunan berkelanjutan secara global. Ini dapat membantu menunjukkan sejauh mana kluster tersebut terkait dengan kebijakan dan inisiatif global terkait perubahan iklim (Wu et al, 2021;Zhao et al, 2023). Faktor geografis juga dapat menjadi elemen overlay yang signifikan, seperti dalam Klaster 2 yang berkaitan dengan isu perkotaan berkelanjutan, yang dapat dianalisis lebih lanjut untuk melihat sejauh mana konsep-konsep dalam kluster tersebut mencerminkan realitas atau tantangan perkotaan di wilayah-wilayah tertentu (Chandra, 2018;Sun et al, 2022).…”

Trends in Preoperative Airway Assessment

“…Complex airway assessment has recently been at the forefront of anesthesia research, with a substantial increase in annual publications during the last 20 years [ 2 ].…”
