The study aims to analyze trends in published articles on regional anesthesia (RA) within emergency medicine (EM) over time.
Analyzed RA-related publications from the SciVerse Scopus database until January 13, 2022.
Focused on trends in annual publications, technique diversity, and characteristics of articles.
Used linear regression analysis to evaluate trends.
A total of 133 publications were identified, showing a rise in RA articles from 1 in 1982 to 18 in 2021.
Lower extremity blocks were the most reported, with 60.90% of citations; thoracic nerve blocks have gained popularity recently.
US authors contributed 41.35% of the RA research, primarily comprising single-shot (88.72%) and ultrasound-guided (55.64%) techniques.
