Abstract：
UNASSIGNED: Postoperative delirium (POD), a common complication affecting short- and long-term prognosis in elderly patients, leads to a heavy burden on social economy and health care. The main purpose of this study is to conduct a bibliometric analysis of the 100 most frequently cited articles on POD.
UNASSIGNED: \"Postoperative delirium\" and its synonyms were searched in the Web of Science (WoS) core database. The top-100 cited articles were automatically selected by sorting the records in descending order. Key information such as author, journal, article type, publication year, citations, since 2013 usage count, institution, country, and keywords were extracted and analyzed. VOSviewer software was applied to do the visualization analyses of institution co-operation, author interaction, author co-citation, and keywords co-occurrence. The CiteSpace software was used to analyze keywords burst.
UNASSIGNED: Most articles were published by authors and institutions in the United States of America (USA). Inouye was the most influential author of this field. The journals that recorded these articles had a high impact factor (IF), with a highest IF of 168.9 and an average IF of 18.04. Cohort studies were the main document type in this field (42 publications), followed by randomized controlled trial (RCT) and systematic reviews or meta-analysis (18 and 14, respectively). The 10 keywords with the highest appearance were \"delirium\", \"risk-factors\", \"surgery\", \"confusion assessment method\", \"elderly patients\", \"hip fracture\", \"intensive care unit\", \"cardiac surgery\", \"general anesthesia\", and \"risk\". Moreover, \"double blind\" and \"cardiac surgery\" were the most recent booming keywords.
UNASSIGNED: We indicated the current research status and tendency of POD by analyzing the 100 most influential articles on POD. The USA is the leader in this field. Prospective study is the preference for authors to cite. Cardiac surgery remains the primary research carrier and the hotspots in the near future may be double-blind studies.

摘要：
■术后谵妄（POD），影响老年患者短期和长期预后的常见并发症，导致社会经济和医疗保健的沉重负担。本研究的主要目的是对100篇最常引用的POD文章进行文献计量分析。
■\“术后谵妄\”及其同义词在WebofScience（WoS）核心数据库中进行搜索。通过按降序对记录进行排序，自动选择引用前100名的文章。关键信息，如作者，journal,文章类型,出版年份,引文,自2013年以来，使用计数，机构,国家,和关键词进行了提取和分析。应用VOSviewer软件对机构合作进行可视化分析，作者互动,作者共同引用，和关键词共现。CiteSpace软件用于分析关键词突发。
■大多数文章由美国（美国）的作者和机构发表。Inouye是该领域最有影响力的作者。记录这些文章的期刊具有很高的影响因子(IF)，最高IF为168.9，平均IF为18.04。队列研究是该领域的主要文件类型(42种出版物)，随后是随机对照试验(RCT)和系统评价或荟萃分析(分别为18和14).外观最高的10个关键词是“谵妄”，“风险因素”，\"手术\",“混淆评估方法”，“老年患者”，“髋部骨折”，\"重症监护室\",“心脏手术”，“全身麻醉”，和“风险”。此外，“双盲”和“心脏手术”是最新的热门关键词。
■我们通过分析有关POD的100篇最有影响力的文章，指出了POD的研究现状和趋势。美国是这一领域的领导者。前瞻性研究是作者引用的首选。心脏外科仍是主要的研究载体，近期的热点可能是双盲研究。
