Data_Sheet_1_A bibliometrics and visualization analysis of ropivacaine research from 2000 to 2023.ZIP

AimBibliometric and data visualization methods were used to identify the current status, key areas, and emerging frontiers in ropivacaine research.
MethodsWe conducted a comprehensive search of the Web of Science database for publications related to ropivacaine published from 2000 to 2023. The publication types were limited to original articles and reviews. We utilized CiteSpace, VOSviewer, and the online bibliometric platform1 to visualize and analyze the collected data.
ResultsA total of 4,147 publications related to ropivacaine were identified, with a consistent growth in annual publications over time. The United States emerged as the most influential country in the field of ropivacaine research, and ranked first in the annual number of publications until 2014. China surpassed the United States in the number of publications for the first time in 2015 and has remained in first place ever since. Of all the research institutions in the field of ropivacaine, University of Copenhagen in Denmark exhibited the highest impact. Brian M. Ilfeld and Casati A were identified as the most influential authors. The leading researchers in this field primarily focused their publications on continuous nerve blocks for postoperative analgesia and ultrasound-guided nerve block techniques. An analysis of reference co-citation clustering revealed 18 distinct research clusters, with current hotspots including erector spinae plane block, dexmedetomidine, quadratus lumborum block, labor analgesia, and mitochondrial respiration. Additionally, keywords analysis indicated that “dexmedetomidine as an adjuvant in nerve blocks” currently represents a research hotspot in the field of ropivacaine.
ConclusionThis bibliometric analysis provides a comprehensive overview of the research landscape in ropivacaine. It reveals research trends in this field and emerging areas for future investigations. Notably, the application of ropivacaine in nerve blocks is a prominent focus in current research, with a particular emphasis on its combination with dexmedetomidine.
