目的 应用计量学方法分析国内外术后认知障碍研究的发文概况与热点。方法 纳入2013-2023年中国知网和Web of Science数据库发表的术后认知障碍相关文献，应用CiteSpace软件统计分析。结果 共纳入中文文献2 705篇，英文核心文献2 412篇。2013-2023年术后认知障碍相关研究发文量逐年增加;中国是国际上发文量最多的国家，中国的首都医科大学发文量居首位;国内术后认知障碍研究以临床研究为主，国外则侧重于病理机制与基础研究。研究热点分析显示，术后认知障碍在炎症机制、麻醉等研究领域中备受关注。结论 2013-2023年，术后认知障碍的国内外研究热度总体呈上升趋势，但其病理、生理机制有待深入研究。术后认知障碍的危险因素、与麻醉及病死率的相关性正被积极探索，经皮电刺激等预防与治疗的新方法逐渐兴起。
Visual analysis in studies at home and abroad on postoperative cognitive impairment based on CiteSpace software
Objective To analyze the publication profile and research hotspots of studies at home and abroad on postoperative cognitive dysfunction by bibliometric methods.Methods Litera-tures related to postoperative cognitive dysfunction published in the China National Knowledge Infra-structure(CNKI)and Web of Science databases from 2013 to 2023 were included,and statistical a-nalysis was conducted by CiteSpace software.Results A total of 2 705 Chinese literatures and 2 412 English core literatures were included.The number of literatures on postoperative cognitive dysfunc-tion showed an annual increase from 2013 to 2023;China was the country with the highest number of publications internationally,with Capital Medical University ranking the top among Chinese institu-tions;domestically,postoperative cognitive dysfunction researches predominantly focused on clinical studies,while overseas researches emphasized pathological mechanisms and basic investigations.Re-search hotspot analysis revealed an enhanced interest in the inflammatory mechanisms and anesthetic as-pects of postoperative cognitive dysfunction.Conclusion From 2013 to 2023,the overall research at home and abroad interest in postoperative cognitive dysfunction has shown an upward trend,yet its patho-physiological mechanisms need further exploration.The risk factors for postoperative cognitive impairment and their correlations with anesthesia and mortality are being actively explored,and new methods for prevention and treatment such as percutaneous electrical stimulation are gradually emerging.
