目的:术后谵妄(POD)是术后最常见的并发症之一,与许多不良结局密切相关。包括高死亡率和低生活质量。本研究旨在对2012-2022年POD及其危险因素进行文献计量分析,以揭示研究现状和热点。
方法:本研究是文献计量和可视化分析。
方法:2012年至2022年的相关出版物来自WebofScienceCoreCollection数据库。CiteSpace软件(v6.1.R2,德雷克塞尔大学),VOSviewer软件(v1.6.18,莱顿大学),利用文献计量在线分析平台对研究属性进行分析。这些出版物被用来分析研究属性,包括国家,期刊,机构,作者,关键词,和突发检测,预测趋势和热点。
结果:我们包含了2012年至2022年的1,324份相关文件。自2016年以来,关于POD的文献大幅增加。美国和哈佛大学是主要的文学出版国(436/1324,32.9%)和机构(112/1324,8.5%)。《麻醉与镇痛》是发表频率最高的期刊。VOSviewer的关键词分析表明,关键词可以分为五个簇,包括麻醉技术,心脏手术,危险因素,术中麻醉监测,和术后认知功能障碍。我们共纳入了198份POD风险因素文件,有关POD危险因素的文献增多。中华人民共和国和哈佛大学是主要的文献出版国(53/198,26.8%)和机构(12/198,6.1%)。老年人,髋关节手术,脆弱,术后疼痛,心脏手术,痴呆症,抑郁症是POD的危险因素。
结论:关于POD在麻醉领域的文献数量明显增加。危险因素和麻醉技术仍然是研究的关键领域。脑电图,使用镇静剂,围手术期护理可能是新的研究热点。老年人,髋部骨折,心脏手术,肝移植,痴呆症,抑郁症是POD危险因素领域的热词。
OBJECTIVE: Postoperative delirium (POD) is one of the most frequent complications after surgery which is closely associated with many adverse outcomes, including high mortality and low quality of life. This study aims to carry out a bibliometric analysis of POD and its risk factors from 2012 to 2022 to reveal the research status and hot spots.
METHODS: This study is a bibliometric and visualized analysis.
METHODS: Relevant publications between 2012 and 2022 were extracted from the Web of Science Core Collection database. CiteSpace software (v6.1. R2, Drexel University), VOSviewer software (v1.6.18, Leiden University), and the Online Analysis Platform of Literature Metrology were used to analyze research attributes. These publications were used to analyze research attributes, including countries, journals, institutions, authors, keywords, and burst detection, to predict trends and hot spots.
RESULTS: We included a total of 1,324 related documents from 2012 to 2022. The literature on POD has increased significantly since 2016. The United States and Harvard University were the leading literature publishing country (436/1324, 32.9%) and institution (112/1324, 8.5%). Anesthesia and Analgesia was the most frequently published journal. Keywords analysis with VOSviewer revealed that the keywords could be divided into five clusters, including anesthesia techniques, cardiac surgery, risk factors, intraoperative anesthesia monitoring, and postoperative cognitive dysfunction. We included a total of 198 POD risk factors documents, and the literature on POD risk factors increased. The People\'s Republic of China and Harvard University were the leading literature publishing country (53/198, 26.8%) and institution (12/198, 6.1%). Elderly, hip surgery, frailty, postoperative pain, cardiac surgery, dementia, and depression are keywords that are risk factors for POD.
CONCLUSIONS: The number of literature on POD in the field of anesthesia has increased significantly. Risk factors and anesthesia techniques are still key areas of research. Encephalogram, the use of sedatives, and perioperative nursing may be the new research focus. Older adults, hip fractures, cardiac surgery, liver transplants, dementia, and depression are hot words in the field of POD risk factors.
