A Comprehensive Overview of the Stellate Ganglion Block Throughout the Past Three Decades: A Bibliometric Analysis.

Abstract

Background: Over the past 3 decades, clinicians and scholars have used and studied the stellate ganglion block (SGB) extensively, making this field a highly anticipated research hot spot. To the best of our knowledge, there has been no bibliometric analysis of the SGB until now.

Objective: Our study aimed to complete multiple tasks regarding SGB research: identify the collaboration and impact of countries, institutions, journals, and authors, evaluate the knowledge base, trace the trends in hot spots, and explore the emerging topics relevant to the field.

Study design: A bibliometric analysis.

Methods: Publications that were associated with the SGB and published between the years of 1993 and 2022 were retrieved from the Web of Science Core Collection on September 21st, 2023. CiteSpace 6.1.R6 and VOSviewer 1.6.18 were used to perform bibliometric and knowledge-map analyses.

Results: This study found a total of 837 publications originating from 51 countries and 1006 institutions. These articles were published in 393 journals. The United States was the country that produced the most articles focused on SGB, and the University of California, Los Angeles was the institution associated with the greatest number of publications. The anesthesiology and cardiology journals surveyed for this study published the most articles and received the most citations. Among the authors whose works were examined, Kitajima T had the greatest number of published articles, and Lipov E was the most frequently cited co-author. Five main domains of SGB research included electrical storm and refractory ventricular arrhythmia, breast cancer and climacteric medicine, post-traumatic stress disorder, pain management, and cerebrovascular diseases. The latest hot topics involving this field focused on SGB's anti-arrhythmic and anti-cerebral vasospasm effects and its treatment of long COVID syndrome.

Limitations: Data were retrieved only from the WoSCC; therefore, publications in other databases might have been missed.

Conclusion: This comprehensive bibliometric analysis conducted a complete overview of SGB research, which was helpful in furthering our understanding of research trends and locating research hot spots and gaps in this domain. This field is developing rapidly and will garner significant and continuous attention from future scholars.
