Extracorporeal membrane oxygenation (ECMO) has been widely used as a life support for different kinds of acute cardiopulmonary dysfunction. The present study aimed at presenting the global trend of the top 100 cited original studies related to ECMO.
Bibliometric analysis was the primary methodology for this study. Literature data were collected from Web of Science Core Collection (WoSCC). Indicators were analyzed and visualized by Excel and VOSviewer, the study design, study population, study topic, journal impact factor (IF), Category Rank and Category Quartile, author, country, journal and keywords were included.
The top 100 cited articles were published between 1979 and 2021. With 19 publications, 2020 was the most prolific year. High-income countries or regions, such as the United States of America (USA), France and Canada owned a majority of the articles. Seventeen studies were randomized trials, 52 were finished in single center, and 53 focused on adults. The 100 articles were documented by 31 different journals. The journals were well recognized, with a mean IF of 28.77, a median of 8.8, and a range of 1.6-168.9. The major diseases were viral infection of respiratory system, acute respiratory distress syndrome (ARDS) or respiratory failure, pulmonary hypertension of infants, heart failure/cardiogenic shock, diaphragmatic hernia and cardiac arrest. Specifically, coronavirus disease 2019 (COVID-19) accounted for 72.7% of viral infections. The disease spectrum changed from congenital cardiopulmonary dysfunction to cardiac arrest, ARDS and cardiopulmonary failure, and to severe COVID infection cases. Another fresh hotspot is immune dysfunction.
This bibliometric analysis identified 100 most frequently cited original studies on ECMO and described their characteristics, which may help with further investigations.
体外膜肺氧合（ECMO）已被广泛用作各种急性心肺功能障碍的生命支持手段。本研究旨在呈现与ECMO相关的被引用次数排名前100的原创研究的全球趋势。
文献计量分析是本研究的主要方法。文献数据从科学引文索引核心合集（WoSCC）收集。通过Excel和VOSviewer对指标进行分析和可视化，纳入的指标包括研究设计、研究人群、研究主题、期刊影响因子（IF）、类别排名和类别四分位数、作者、国家、期刊和关键词。
排名前100的被引用文章发表于1979年至2021年之间。2020年发表了19篇文章，是发表量最多的一年。美国、法国和加拿大等高收入国家或地区拥有大部分文章。17项研究为随机试验，52项在单中心完成，53项聚焦于成人。这100篇文章发表在31种不同的期刊上。这些期刊认可度较高，平均影响因子为28.77，中位数为8.8，范围为1.6 - 168.9。主要疾病包括呼吸系统病毒感染、急性呼吸窘迫综合征（ARDS）或呼吸衰竭、婴儿肺动脉高压、心力衰竭/心源性休克、膈疝和心脏骤停。具体而言，2019冠状病毒病（COVID - 19）占病毒感染的72.7%。疾病谱从先天性心肺功能障碍转变为心脏骤停、ARDS和心肺衰竭，再到严重的COVID感染病例。另一个新热点是免疫功能障碍。
这项文献计量分析确定了100篇关于ECMO的最常被引用的原创研究，并描述了它们的特征，这可能有助于进一步的研究。
