中文摘要:
      
目的：采用文献计量学和可视化方法分析近20年关于右美托咪定预防术后神经认知障碍的研究热点和趋势。
方法：检索Web of Science核心数据库中2006年1月至2024年8月有关右美托咪定预防术后神经认知障碍的文献，采用VOSviewer软件进行可视化分析。
结果：本研究共纳入159篇文献。有关右美托咪定预防术后神经认知障碍的年度发文量总体呈上升趋势，并于2017年后呈现显著增长。中国学者发文量最多，英国学者篇均被次数为最多，BMC Anesthesiology的发文量居第一位，Anesthesiology是共被引频次最多的期刊，Lancet上发表的一篇关于右美托咪定预防术后谵妄的研究是共被引频次最多的文献。术后谵妄、谵妄、镇静状态、老年患者、心脏手术、危重患者为研究热点关键词，苏醒期谵妄作为近期新兴的关键词呈现显著的增长趋势。
结论： 右美托咪定预防术后神经认知障碍是一个快速发展且日益受到关注的研究领域，当前研究重点集中于老年患者心脏手术后谵妄的防治，研究前沿正转向苏醒期谵妄，该领域未来在机制探索与临床转化方面仍具有持续的探索价值。
英文摘要:
      
Objective: To analyze the research hotspots and trends of dexmedetomidine in preventing postoperative neurocognitive disorders in recent years using bibliometric and visual analysis methods.
Methods: Literature on dexmedetomidine for postoperative neurocognitive disorders prevention from January 2006 to August 2024 was retrieved from the Web of Science Core Collection. The VOSviewer software was used to perform visual analysis.
Results: A total of 159 articles were included. The annual publication volume about dexmedetomidine in preventing postoperative neurocognitive disorders showed an overall upward trend, with significant growth observed after 2017. Chinese scholars leaded in publication count and British scholars achieved the highest average citations per article. BMC Anesthesiology ranked first in publication volume, while Anesthesiology was the most co-cited journal. A study on dexmedetomidine for postoperative delirium prevention published in Lancet had the highest co-citation frequency. Hotspot analysis identified keywords such as “postoperative delirium” “delirium” “sedation” “elderly patients” “cardiac surgery” and “critically ill patients”, “emergence delirium” emerging as a rapidly growing recent keyword.
Conclusion: Dexmedetomidine in preventing postoperative neurocognitive disorders is a rapidly evolving and increasingly focused research field. Current research priorities emphasize delirium prevention in elderly patients undergoing cardiac surgery, while the frontier is shifting toward emergence delirium. This area remains valuable for future mechanistic exploration and clinical translation.
