Perioperative neurocognitive disorder (PND) has attracted consistently increasing attention worldwide. However, there are few bibliometric studies that systematically evaluate this field. This study aimed to visualize the knowledge structure and research trends in PND through bibliometrics to help understand the future development of basic and clinical research.
Literature related to PND in Web of Science and PubMed from 1990 to 2022 were collected through keywords retrospectively. Additionally, the source information, citation information, etc. of these publications were extracted. Finally, bibliometric analysis was performed by visualization software and statistical software.
There were 2837 articles and reviews in total. An exponential rise in PND-related publications was observed. China had the most publication, followed by the US and Germany. The institution with the most output and citations was Harvard University (149 papers, 8966 citations). The most prominent author was Marcantonio Edward R with 66 publications and 5721 citations. The journal with the highest productivity for PND research was followed by . Keywords were identified as six topics, including postoperative delirium, postoperative neurocognitive disorder, cardiac surgery, anaesthesia, orthopedic surgery, and dementia. According to keyword analysis, the most recent popular keywords in PND research were prevention, older patients, emergence delirium, orthopedic surgery, and dexmedetomidine.
Publications on PND are increasing at an alarming rate from 1990 to 2022. Current research and future trends will concentrate on the prevention and treatment of PND, as well as PND associated with orthopedic surgery in older adults.
围手术期神经认知障碍（PND）在全球范围内一直受到越来越多的关注。然而，很少有文献计量学研究系统地评估这一领域。本研究旨在通过文献计量学可视化PND的知识结构和研究趋势，以帮助理解基础研究和临床研究的未来发展。
通过关键词回顾性收集1990年至2022年Web of Science和PubMed中与PND相关的文献。此外，提取这些出版物的来源信息、引用信息等。最后，通过可视化软件和统计软件进行文献计量分析。
共纳入2837篇文章和综述。观察到PND相关出版物呈指数增长。中国的出版物数量最多，其次是美国和德国。产出和引用最多的机构是哈佛大学（149篇论文，8966次引用）。最杰出的作者是Marcantonio Edward R，发表了66篇论文，被引用5721次。PND研究生产力最高的期刊是 ，其次是 。关键词被确定为六个主题，包括术后谵妄、术后神经认知障碍、心脏手术、麻醉、骨科手术和痴呆。根据关键词分析，PND研究中最新的热门关键词是预防、老年患者、苏醒期谵妄、骨科手术和右美托咪定。
1990年至2022年期间，关于PND的出版物正以惊人的速度增长。当前的研究和未来趋势将集中在PND的预防和治疗，以及与老年人骨科手术相关的PND。
