目的 分析ICU机械通气患者早期活动的研究热点和发展趋势。方法 检索2000-2023年中国知网和Web of Science数据库收录的ICU机械通气患者早期活动相关文献。采用CiteSpace可视化软件进行文献分析，并以图谱形式展现文献的发表量、关键词。分析该领域的研究热点与问题。结果 检索得到ICU机械通气患者早期活动相关中文文献共116篇，英文文献共145篇。英文文献发文量在波动中增长，中文文献发文量整体稳步增长，均于2020年小幅度回落。研究热点集中于早期活动、机械通气、ICU获得性衰弱、谵妄。中文文献形成早期活动、机械通气、护理、综述、肌力等11个聚类;英文文献形成critical care、delirium、pilot study等10个聚类。2023年的高频关键词是目标导向。结论 国内外学者对ICU机械通气患者早期活动的关注度较高，热点聚焦于早期活动对疾病的影响和效果评价。该领域研究内容较丰富，但循证实践研究较少。
Research hotspots and trends of early mobilization in ICU patients with mechanical ventilation based on CiteSpace software
Objective To analyze the research hotspots and trends of early mobilization in ICU patients with mechanical ventilation.Methods The literature on early mobilization of ICU patients with mechanical ventilation included in the China National Knowledge Infrastructure(CNKI)and Web of Science databases from 2000 to 2023 was searched.CiteSpace visualization software was used for literature analysis,and the publication volume and keywords of the literature were displayed in the form of maps.The research hotspots and problems in this field were analyzed.Results A total of 116 Chinese articles and 145 English articles related to early mobilization in ICU patients with me-chanical ventilation were retrieved.The number of English articles increased with fluctuations,while the number of Chinese articles showed a steady growth trend overall,both of which fell slightly in 2020.The research focused on early mobilization,mechanical ventilation,ICU-acquired weakness and delirium.Chinese articles formed 11 clusters such as early mobilization,mechanical ventilation,nursing,review and muscle strength;English articles formed 10 clusters such as critical care,deliri-um and pilot study.The high-frequency keyword in 2023 was goal-directed.Conclusion Domestic and foreign scholars pay high attention to the early mobilization of ICU patients with mechanical venti-lation,focusing on the impact of early mobilization on diseases and the evaluation of its effects.The research content in this field is rich,but there are few evidence-based practical studies.
