分析国际及中国2020年至2024年重症医学领域临床研究，探究重症医学研究的现状、热点和研究方向。

采用文献计量学的方法论，利用CiteSpace和VOSviewer软件对重症医学领域临床研究进行详细分析。分析基于WoS数据库，覆盖出版时间在2020年1月1日至2024年12月30日的8350篇临床研究，重点分析国际合作、作者合作网络、关键词共现和高被引论文情况。

研究纳入128个国家和地区的8350篇临床研究，其中美国以3563篇发文量位居首位；国际合作网络分析显示，发文量前3位依次是美国、法国和英国。合作的中心性的前3位分别是北爱尔兰、中国和丹麦；关键词共现分析显示研究热点聚焦于“脓毒症”“指南”“急性呼吸窘迫综合征”“儿童”“机械通气”等方向。统计周期内共有153篇高被引论文，其中前5位论文（被引761~5549次）发表于The Lancet Respiratory Medicine和Intensive Care Medicine，研究主题集中于新型冠状病毒感染（COVID-19）和脓毒症，国际最高被引论文来自中国；中国研究者参与的前5位高被引论文（非主要作者）被引频次为600~5549次，而以中国研究者为主要作者的前5位论文被引频次是178~5549次。

美国、法国、澳大利亚、加拿大等国家是重症医学领域科研的主力军，并在全球科研合作网络中占据核心位置。中国广泛的国际合作网络尚未形成，但是合作的中心性明显增强。

To conduct a bibliometric analysis of clinical research in the field of critical care medicine from 2020 to 2024, both internationally and in China, in order to identify current status, hotspots, and emerging trends.

A bibliometric methodology was employed. Clinical studies were analyzed using CiteSpace and VOSviewer software. The analysis was based on the Web of Science (WoS) core collection database, encompassing 8350 clinical studies published between January 1, 2020 and December 30, 2024. The analysis focused on international collaboration, patterns, author collaboration networks, keyword co-occurrence, and the characteristics of highly cited papers.

The study included 8350 clinical studies from 128 countries and regions. The United States led in publication output with 3563 articles. Analysis of the international collaboration network showed that the top three countries in publication volume were the United States, France, and the United Kingdom. The top three in terms of collaboration centrality were Northern Ireland, China, and Denmark. Keyword co-occurrence analysis identified major research hotspots including “Sepsis”, “Guidelines”, “Acute Respiratory Distress Syndrome”, “Children”， and “Mechanical ventilation”. Within the study period, 153 papers were identified as highly cited. The top 5 most cited papers (cited range: 761 to 5549) were published in the Lancet Respiratory Medicine and Intensive Care Medicine, with research themes concentrated on COVID-19 and Sepsis. The single highest internationally cited paper originated from China. The top 5 highly cited papers with Chinese researchers as participating (non-leading) authors had a citation range of 600 to 5549, while the top 5 papers with Chinese researchers as lead authors were cited 178 to 5549 times.

Countries including the United States, France, Australia, and Canada are the main driving forces in critical care medicine research and occupy central positions in the global scientific collaboration network. While a broad and extensive international cooperation network for China has not yet fully formed, its centrality within the existing network has significantly increased, indicating a growing influence.
