目的:对我国无痛胃镜领域的高被引文献进行计量学分析。方法:以中国学术期刊全文数据库(CNKI)为数据源,检索2013年11月7日至2023年11月7日期间发表的无痛胃镜相关文献。依据普赖斯定律筛选高被引文献,并运用Excel 2021软件对文献的被引...目的:对我国无痛胃镜领域的高被引文献进行计量学分析。方法:以中国学术期刊全文数据库(CNKI)为数据源,检索2013年11月7日至2023年11月7日期间发表的无痛胃镜相关文献。依据普赖斯定律筛选高被引文献,并运用Excel 2021软件对文献的被引频次、发表年份、来源期刊、作者信息、机构分布、关键词及基金资助情况等计量学特征进行统计分析。结果:共筛选出251篇高被引文献,单篇被引频次介于9至118次之间,累计被引4264次,篇均被引16.99次。无痛胃镜高被引文献数量于2017年达到峰值,随后呈现下降趋势。251篇高被引文献分布于128种期刊中,其中《临床麻醉学杂志》《现代消化及介入诊疗》《中外医学研究》《山东医药》《实用临床医药杂志》《河北医药》《实用医学杂志》《中国临床研究》《中国内镜杂志》文献数依次位居前九位;涉及作者736人,累计合作186篇,总合作率74.10%;共涉及机构267个,其中河北省廊坊市第四人民医院、青岛市中心医院、上海交通大学、郑州大学文献居于前4位;共涉及关键词309个、1005次,其中“无痛胃镜”、“丙泊酚”出现次数居于前二;61篇文献获得73项次项目基金支持。Objective: To analyze the bibliometric characteristics of highly cited literature on painless gastroscopy in China. Methods: Literature on painless gastroscopy published between November 7, 2013, and November 7, 2023, was retrieved from the China National Knowledge Infrastructure (CNKI) database. Highly cited literature was identified based on Price’s Law, and statistical analysis of citations, publication year, journals, authors, institutions, keywords, and funding was conducted using Excel 2021. Results: A total of 251 highly cited articles were identified, with citation counts ranging from 9 to 118, totaling 4264 citations and an average of 16.99 citations per article. The number of highly cited articles on painless gastroscopy peaked in 2017 and subsequently declined. The 251 articles were published in 128 journals, with Journal of Clinical Anesthesiology, Modern Digestion & Intervention, Chinese and Foreign Medical Research, Shandong Medical Journal, Journal of Clinical Medicine in Practice, Hebei Medical Journal, Journal of Practical Medicine, Chinese Journal of Clinical Research, and Chinese Journal of Endoscopy ranking in the top nine in terms of the number of articles published. A total of 736 authors were involved, with 186 articles co-authored, resulting in a collaboration rate of 74.10%. The articles involved 267 institutions, with the Fourth People’s Hospital of Langfang in Hebei Province, Qingdao Central Hospital, Shanghai Jiao Tong University, and Zhengzhou University ranking in the top four. A total of 309 keywords appeared 1005 times, among them, the number of occurrences of “painless gastroscopy” and “propofol” ranked in the top two;Sixty-one articles received support from 73 funding projects.展开更多
