目的 分析近20年国内外输液港研究的发展现状、发展热点与前沿，为相关研究提供参考。方法 使用CiteSpace 6.3对Web of Science 核心数据库，知网、万方、维普等中文数据库2002年1月至2022年12月收录的输液港相关文献进行分析。结果 最终纳入中文文献1310篇、英文文献687篇。中英文研究热点相近，其中护理教育、无损伤针是中文特有的研究热点，聚维酮碘是英文特有的研究热点；疼痛为中文文献的研究前沿，输液港植入方式、位置、风险因素筛查、患者结局、生活质量为英文文献的研究前沿。结论 国内外输液港研究整体呈上升趋势，我国输液港临床实践发展迅速。国内外输液港研究水平相近，利用多种机会分享中国经验、合力拓展输液港研究广度将是护理人员未来需思考的重点。

Objective To analyze the current status of research，hotpots，and frontiers of the totally implantable venous access device in the last two decades in China and abroad，so as to provide reference for totally implantable venous access device research in China.Methods Journal articles from the core database of Web of Science，CNKI，Wanfang and VIP from January 2002 to December 2022 were researched and retrieved with keywords of totally implantable venous access device.CiteSpace 6.3 software was used to analyzed the literature.Results A total of 1310 Chinese and 687 English literatures were included.Chinese and English research hotspots are similar，with nursing education and non-destructive needle being unique research hotspots in Chinese，and povidone iodine being a unique research hotspot in English.Pain is at the forefront of Chinese literature，while implantation method，location，risk factor screening，patient outcome and quality of life are at the forefront of English literature.Conclusions The research on totally implantable venous access device is on the rise both domestically and aboard，and the clinical practice in China is developing rapidly.With similar research levels of totally implantable venous access device at home and abroad，taking advantage of multiple opportunities to share China’s experience and combine efforts to expand the breadth of totally implantable venous access device research will be a key focus for nursing staff to think about in the future.
