Postoperative sleep disturbance (PSD) is highly prevalent and significantly affects patient prognosis. Studies on PSD have received increasing attention, resulting in a surge in related publications. However, comprehensive analyses that can objectively reflect changes in scientific knowledge and identify the latest research trends in this field are lacking.
Articles and reviews focusing on PSD were extracted from the Web of Science Core Collection database. Bibliometrix, VOSviewer, and CiteSpace were used to conduct bibliometric analysis and map the visualization network.
A total of 1,559 publications were extracted from the database, including 1,370 articles and 189 reviews. There has been a consistent increase in the number of publications, with an average annual growth rate of 16.56%, led by the United States in terms of research output. Notably, the University of Toronto was a prominent contributor. Co-cited reference network analysis revealed 17 well-structured networks (Q = 0.8174, S = 0.9441). Six major research trends were identified: mechanisms of sleep related to anesthesia, role of melatonin in sleep disturbances, pain management strategies, effects of analgesic drugs, impact of dexmedetomidine on sleep quality, and postoperative recovery. Keywords analysis highlighted the emerging roles of dexmedetomidine, neuroinflammation, and acupuncture.
Bibliometric analysis provides a helpful summary of postoperative sleep disturbances that have changed over time, by identifying knowledge points and developing trends. Future research should focus on integrating multidisciplinary approaches, exploring neuroinflammation, evaluating non-pharmacological interventions and long-term outcomes, which will advance scientific knowledge, enhance clinical practice, and improve patient outcomes and quality of life.
术后睡眠障碍（PSD）非常普遍，且对患者预后有显著影响。关于PSD的研究受到越来越多的关注，相关出版物激增。然而，缺乏能够客观反映科学知识变化并识别该领域最新研究趋势的综合分析。
从Web of Science核心合集数据库中提取聚焦于PSD的文章和综述。使用Bibliometrix、VOSviewer和CiteSpace进行文献计量分析并绘制可视化网络。
从数据库中总共提取了1559篇出版物，包括1370篇文章和189篇综述。出版物数量持续增加，平均年增长率为16.56%，美国在研究产出方面领先。值得注意的是，多伦多大学是一个突出的贡献者。共被引参考文献网络分析揭示了17个结构良好的网络（Q = 0.8174，S = 0.9441）。确定了六个主要研究趋势：与麻醉相关的睡眠机制、褪黑素在睡眠障碍中的作用、疼痛管理策略、镇痛药的作用、右美托咪定对睡眠质量的影响以及术后恢复。关键词分析突出了右美托咪定、神经炎症和针灸的新兴作用。
文献计量分析通过识别知识点和发展趋势，对随时间变化的术后睡眠障碍提供了有益的总结。未来的研究应侧重于整合多学科方法、探索神经炎症、评估非药物干预措施和长期结果，这将推动科学知识发展、加强临床实践并改善患者预后和生活质量。
