Abstract:

Objective

To analyze recent 10 years literature on inhalation injury， and to explore the current situation and frontiers in this field.

Methods

Using bibliometric methods searched for Chinese and English literature related to inhalation injury published from January 1， 2015， to July 5， 2024， in China National Knowledge Infrastructure （CNKI）， Wanfang Database， VIP Database， and Web of Science Core Collection，and utilized CiteSpace 6.1.R6 software for analysis.The publication volume， authors， countries and institutions of both Chinese and English literature were statistically analyzed. Co-occurrence analysis of keywords was performed， followed by cluster analysis and burst detection. Keywords were sorted by time to obtain a cluster timeline， exploring the current research status and the evolution of hotspots in the field of inhalation injury.

Results

A total of 609 English articles were retrieved from the Web of Science Core Collection， and 521 Chinese articles were obtained after deduplication from CNKI， Wanfang Database， and VIP Database. From 2015 to 2024， the number of English publications in the field of inhalation injury showed a steady upward trend， while the number of Chinese publications showed a declining and then stabilizing trend. In the Chinese literature， 289 authors published articles on inhalation injury as the first author， with 32 core authors publishing three or more articles. In the English literature， 353 authors published articles as the first author. A total of 56 countries conducted research on inhalation injury， with the United States being the country with the most collaborations and publications. A total of 497 institutions published articles on inhalation injury， with the First Affiliated Hospital of Nanchang University （25 articles） and the University of Texas Medical Branch （37 articles） being the institutions with the most publications in Chinese and English， respectively. A co-occurrence analysis of 308 Chinese keywords and 330 English keywords was conducted. After excluding keywords related to search terms， the Chinese literature frequently featured keywords such as nursing， tracheotomy， and risk factors， while the English literature frequently featured keywords such as mortality， management， and epidemiology. The Chinese keyword analysis identified 38 clusters， with the largest clusters being risk factors， followed by nursing and severe burns. Recent burst nodes included indicator system and drug resistance. The English keyword analysis identified 18 clusters， with the largest clusters being baux score， followed by extracorporeal membrane oxygenation and acute kidney injury. Recent burst nodes included intubation and difficult airway.In the Chinese literature， the keyword with the longest burst duration （2021-2024） and highest burst strength was risk factors. In the English literature， the keyword with the longest burst duration （2016-2019）and highest burst strength was acute respiratory distress syndrome.

Conclusion

Epidemiological studies on inhalation injury in China are scarce. In the future， the development of diagnostic and assessment criteria for evaluating the condition of patients with inhalation injury is expected to become a significant trend， which can aid clinicians in determining the optimal timing for tracheostomy and improve patient outcomes.
