虚拟现实技术在手术患者中应用研究热点的可视化分析

Research hotspots on the application of virtual reality technologyin surgical patients: a visual analysis

目的对虚拟现实(VR)技术在外科手术患者中的应用研究热点进行总结,了解其发展现状和趋势。方法以“virtual reality”“operation”等为主题词,检索Web of Science核心合集中收录的从建库至2023年7月VR在手术患者中应用的相关文献,导入书目共现分析系统进行高频关键词的提取,生成词篇矩阵;使用gCLUTO软件进行共词聚类分析,生成聚类矩阵图及可视化山丘图。结果共检索到1672篇文献,经去重及筛选后最终纳入有效文献354篇。获得高频关键词27个,聚类分析得出4个热点,归为3个方向:VR技术改进及与其他技术的结合研究、VR技术与患者结局指标相关的研究、VR技术提高手术医护人员技能的研究。结论当前VR技术在手术患者中的应用研究发展迅速,未来可着眼于VR设备的改进设计、老年术后康复等方向进行进一步的研究。

Objective To find out the development status and trends of virtual reality (VR) technology in surgical patients by summarizing the research hotspots in its application.Methods With “virtual reality” and “operation” as the subject words, the relevant literature on the application of VR technology in surgical patients from the establishment of the database to July 2023 was retrieved in the core collection of Web of Science, and the bibliographic co-occurrence analysis system was introduced to extract high-frequency keywords and generate a word matrix. The gCLUTO was used for co-word clustering analysis to generate clustering matrix diagrams and visual hill maps.Results A total of 1 672 articles were retrieved, and 354 effective articles were ultimately included after deduplication and screening. There were 27 high-frequency keywords obtained, and cluster analysis identified 4 hotspots, which were classified into 3 directions: research on VR technology improvement and integration with other technologies, research on VR technology and patient outcome indicators, and research on VR technology improving the skills of surgical staff.Conclusion The current research on the application of VR technology in surgical patients is rapidly developing. In the future, further research can focus on improving the design of VR devices and elderly postoperative rehabilitation.
