院外心脏骤停领域的研究进展和热点追踪

Out-of-hospital cardiac arrest research progress and hotspot tracking

目的利用文献计量学方法对院外心脏骤停(OHCA)的研究重点和趋势进行归纳总结。方法基于WOS核心数据库检索至今为止OHCA相关文献,采用CiteSpace软件、文献计量在线分析平台以及基于R语言的Biblioshiny软件包对该领域的文献产出情况、国家/地区、机构、作者、期刊、关键词、参考文献等维度进行可视化分析。结果经筛选共纳入相关文献7642篇。全球范围内OHCA文献发表数量呈现逐年上升趋势。在国家发文量排名中,中国位列第六位。当前OHCA研究重点主要围绕急救医疗服务体系、急救措施、病因和预后以及ROSC后管理策略四个方面。其中,"自动体外除颤器"、"ROSC后目标体温管理"、"体外膜肺氧合"、"气道管理"、"远程指导心肺复苏"已成为当前研究的热点。结论近年来OHCA领域的研究产出显著增长,上述热点主题将继续成为未来研究的焦点。尽管OHCA救治面临诸多挑战,但随着紧急医疗服务系统的不断完善、更多抢救措施的开展,OHCA救治仍是患者提高生存率和改善预后的重要议题。

Objective To summarize the research focus and trends on out-of-hospital cardiac arrest(OHCA)by using bibliometric methods.Methods Based on the WOS core database search up to now,literatures related to OHCA were analyzed using the CiteSpace software,the online bibliometric analysis platform,and the biblioshiny software package with the R language,to visually analyze the literature output in this field from dimensions such as country/region,institutions,authors,journals,keywords,references,etc.Results A total of 7642 related documents were included after screening.The number of publications on OHCA worldwide showed an annual upward trend.In the ranking of national publication volume,China was ranked sixth.The current focus of OHCA research was mainly revolved in four aspects:emergency medical services system,emergency measures,etiology and prognosis,as well as management strategies after ROSC.Among them,"automated external defibrillator","ROSC targeted temperature management","extracorporeal cardiopulmonary resuscitation","airway management",and"remote command CPR"had become hot topics in current research.Conclusion In recent years,there has been a significant increase in research output in the OHCA field,and the aforementioned hot topics will continue to be the focus of future research.Despite facing numerous challenges,OHCA treatment remains an important issue for patients to improve survival rates and prognosis as emergency medical services continue to improve and more rescue measures are implemented.
