To review the literature related to bronchopulmonary dysplasia in extremely pre-mature infants, summarize research direction, and report trends. CiteSpace is a Java application which supports visual exploration with knowledge discovery in bibliographic databases. Relevant articles from 2008 to 2020 were retrieved from the Web of Science Core Collection database, and we extracted the following data: title, abstract, year, keywords, author, organization, journal and cited literature. We downloaded the data into CiteSpace (version 5.7.R3) to summarize countries, institutions, journals, and authors. We visualized the data with a knowledge map, collaborative network analysis, cluster analysis, and burst keyword analysis. We identified 610 articles on bronchopulmonary dysplasia in extremely pre-mature infants. The United States had the most articles on this topic (302 articles), followed by Canada (49 articles) and Germany (44 articles). The top three institutions, high-yield journals, and authors were all from the United States. The most common keywords were neurodevelopmental disorders, active perinatal care, mechanical ventilation, inflammation, pulmonary hypertension, low-dose hydrocortisone, development, and patent ductus arteriosus. This study illustrates the trends and frontiers in the study of bronchopulmonary dysplasia in extremely pre-mature infants. The current research direction is to identify the risk factors in developing bronchopulmonary dysplasia in extremely pre-mature infants.
回顾与极早产儿支气管肺发育不良相关的文献，总结研究方向并报告趋势。CiteSpace是一款支持在文献数据库中进行知识发现的可视化探索的Java应用程序。从科学网核心合集数据库中检索2008年至2020年的相关文章，并提取以下数据：标题、摘要、年份、关键词、作者、机构、期刊和被引文献。我们将数据下载到CiteSpace（版本5.7.R3）中，以总结国家、机构、期刊和作者。我们通过知识图谱、合作网络分析、聚类分析和突发关键词分析对数据进行可视化处理。我们确定了610篇关于极早产儿支气管肺发育不良的文章。美国关于该主题的文章最多（302篇），其次是加拿大（49篇）和德国（44篇）。排名前三的机构、高产期刊和作者均来自美国。最常见的关键词是神经发育障碍、围产期积极护理、机械通气、炎症、肺动脉高压、低剂量氢化可的松、发育和动脉导管未闭。本研究阐述了极早产儿支气管肺发育不良研究的趋势和前沿。当前的研究方向是确定极早产儿发生支气管肺发育不良的风险因素。
