摘要目的:运用文献计量学方法分析超声技术在我国鼻肠管置管应用的研究现状与发展趋势，为今后的研究提供参考。方法:检索中国期刊全文数据库（CNKI）、万方期刊全文数据库、中国生物医学文献数据库（CBM）和维普中文科技期刊数据库（VIP）中鼻肠管置管应用超声技术的相关文献进行分析，时间从建库至2019年9月以前。结果:共检出54篇有效文献，发表在国内40种期刊上，文献数量呈逐年上涨趋势。核心期刊刊载量占57.41%；基金文献所占比例为25.93%；文献类型以实验性研究和类实验研究最多，占文献总量的88.89 %；研究对象主要为成人危重症患者，占比为98.15%，主要研究内容是超声引导或辅助下鼻肠管置管与超声鼻肠管定位。结论:我国超声技术在鼻肠管置管中应用的研究尚处于起步阶段，发展速度较快；但研究地区分布不平衡，研究的深度与广度不够，研究类型和研究内容相对局限。今后需开展多中心、大样本的研究，将量性研究与质性研究相结合，关注重症儿童鼻肠管应用，拓宽研究内容的广度和深度。

abstractsObjective:To provide reference for future research based on bibliometric analysis on research status and developing trend of the application of ultrasonography for insertion of naso-intestinal tubes in China.Methods:All published literatures on the application of ultrasonography for insertion of naso-intestinal tubes were retrieved from CNKI, Wanfang Database, CBM and VIP before September 2019.Results:A total of 54 effective literatures were included and published in 40 Chinese journals and the number of literatures increased year by year. The core journals accounted for 57.41% and the fund literature accounted for 25.93% of the total literature. Experimental and quasi-experimental studies, accounted for 88.89% of the total literature. The main subjects were adult critically ill patients, accounting for 98.15%. The main research contents of the included studies were ultrasound-guided naso-intestinal tube placement and ultrasonic naso-intestinal tube localization.Conclusions:Studies on the ultrasonography for insertion of naso-intestinal tubes in China is still in its initial stage and are developing rapidly. While the distribution of the research area is unbalanced, the depth and scope of the studies are not enough, and the research types and contents are relatively limited. In the future, it is necessary to carry out multicenter and large sample research, combine quantitative research with qualitative research, pay more attention to the application of nasal-intestinal tube in critically ill children to broaden the breadth and scope of the research content.
