Research progress of early brain Injury in subarachnoid hemorrhage from 2004 to 2024: a bibliometric analysis.

Early brain injury (EBI) after subarachnoid hemorrhage (SAH) is a clear correlation with poor prognosis. In the past 20 years, the research on EBI has increased rapidly. However, there is a lack of bibliometric analysis related to EBI. The purpose of this study was to identify emerging targets for the treatment of EBI and analyze the current situation and trend of EBI post-SAH in the past 20 years through bibliometric analysis. EBI related literature was retrieved from Web of Science Core Collection during 2004-2024, and analyzed by Microsoft Office Excel 2023, CiteSpace, and VOSviewer. 1364 articles were retrieved, and finally 1271 articles were involved in the analysis. The number of EBI-related articles has grown steadily over the past 20 years. China cooperated most closely with other countries. Loma Linda University was the most productive institution and John H Zhang was the most prolific author. The most productive and co-cited journals were Translational Stroke Research and Stroke, respectively. The burst keywords suggested that EBI research was focusing on cell inflammation and multiple mechanisms of cell damage. This is the first bibliometric analysis of EBI-related studies after SAH. As a critical period for the treatment of SAH, our study will provide a good direction for future investigators.
