RESUMO
Objective:To analyze the research hotspots and development trend of the application of artificial intelligence to the field of anesthesia using bibliometrics, and to provide reference for further research.Methods:Based on the results of the literature search on artificial intelligence and anesthesia in the Web of Science database, Citespace5.5.R2 and VOSviewer1.6.16 softwares were used to draw the knowledge map of scientific research cooperation networks, keywords and citations and implement bibliometric analysis.Results:A total of 298 studies were included, and the number of publications and citation frequency in the early period were maintained at a very low level for a long time, and both showed an increasing trend year by year after 2017.These studies came from 45 countries/regions, among which the United States had the highest publications.Harvard University was the institution with the highest number of papers.The author with the highest publications was Matava Clyde, who worked at the Toronto Hospital for Sick Children.Research on the application of artificial intelligence to the field of anesthesia had mainly focused on artificial intelligence algorithms, event prediction, anesthesia control and pain management.Conclusions:The application of artificial intelligence to the field of anesthesia has gradually attracted the attention of the academic community in the past five years, and the number of publications and citation frequency have increased drastically.The academic achievements in this field in China still have a gap compared with the world advanced level, and more in-depth researches can be conducted in the future for the hot directions.
