Global Trends of Gastrointestinal Endoscopy Anesthesia/Sedation: A Bibliometric Study (from 2001 to 2022)

Abstract

Background

Gastrointestinal (GI) endoscopy becomes more and more common now in order to diagnose and treat GI diseases, and anesthesia/sedation plays an important role. We aim to discuss the developmental trends and evaluate the research hotspots using bibliometric methods for GI endoscopy anesthesia/sedation in the past two decades.

Methods

The original and review articles published from 2001 to December 2022 related to GI endoscopy anesthesia/sedation were extracted from the Web of Science database. Four different softwares (CiteSpace, VOSviewer, and Bibliometrix, Online Analysis Platform of Literature Metrology (Bibliometric)) were used for this comprehensive analysis.

Results

According to our retrieval strategy, we found a total of 3154 related literatures. Original research articles were 2855, and reviews were 299. There has been a substantial increase in the research on GI endoscopy anesthesia/sedation in recent 22 years. These publications have been cited 66,418 times, with a mean of 21.04 citations per publication. The US maintained a leading position in global research, with the largest number of publications (29.94%), and China ranked second (19.92%). Keyword burst and concurrence showed that conscious sedation, colonoscopy and midazolam were the most frequently occurring keywords.

Conclusion

Our research found that GI endoscopy anesthesia/sedation was in a period of rapid development and demonstrated the improvement of medical instruments and surgical options that had significantly contributed to the field of GI endoscopy anesthesia/sedation. The US dominates this field, and the selection and dosage of sedative regimens have always been the foci of disease research to improve comfort and safety, while adverse events and risks arouse attention gradually. In the past 20 years, hotspots mainly focus on upper gastrointestinal endoscopy, gastroscopy, and esophagogastroduodenoscopy. These data would provide future directions for clinicians and researchers regarding GI endoscopy anesthesia/sedation.
