Abstract
Objective: To analyze the hotspots and frontiers in the field of subarachnoid hemorrhage using the bibliometrics method and providing references for academic research.
Methods: All published studies related to subarachnoid hemorrhage published in the Web of Science core database from 1 January 2016 to 25 September 2021 were retrospectively identified using VOSviewer and CiteSpace software. Visualization VOSviewer and CiteSpace software were used to perform statistical and cluster analyses on authors, countries, institutions, keywords, and co-cited documents. Knowledge graphs were drawn.
Results: A total of 7151 research papers related to subarachnoid hemorrhage were included for analysis. The number of papers on subarachnoid hemorrhage research showed an upward trend. The leading countries in subarachnoid hemorrhage research were the United States, China, and Japan. In addition, the Harvard Medical School, the Mayo Clinic, and the Capital Medical University were leading authorities subarachnoid hemorrhage research. The common keywords formed 7 clusters. There were 13 clusters of citations.
Conclusions: Research hotspots and directions in subarachnoid hemorrhage research were identified, such as cerebral aneurysm, early brain injury, vasospasm, and prognosis model.
目的：运用文献计量学方法分析蛛网膜下腔出血领域的热点和前沿，为学术研究提供参考。方法：使用VOSviewer和CiteSpace软件对2016年1月1日至2021年9月25日在Web of Science核心数据库中发表的所有与蛛网膜下腔出血相关的研究进行回顾性分析。利用可视化软件VOSviewer和CiteSpace对作者、国家、机构、关键词、共被引文献进行统计和聚类分析。绘制知识图谱。结果：共纳入蛛网膜下腔出血相关文献7151篇。蛛网膜下腔出血研究论文数量呈上升趋势。蛛网膜下腔出血研究的主要国家是美国、中国和日本。此外，哈佛大学医学院、梅奥诊所、首都医科大学是研究蛛网膜下腔出血的权威机构。常见关键词组成7个集群。共有13组引文。结论：明确了脑动脉瘤、早期脑损伤、血管痉挛、预后模型等蛛网膜下腔出血研究的热点和方向。
