چکیده

Background and Objectives: Early brain injury (EBI) occurs within the first 72 hours after subarachnoid hemorrhage (SAH) and strongly influences morbidity and mortality. This study mapped EBI-after-SAH research using title-level Web of Science bibliometric analysis.     Methods: We searched the WoS Core Collection for title records containing “early brain injury” AND “subarachnoid hemorrhage,” including original SCI/SCI-E articles published before January 1, 2024. We extracted publication year, language, journal/publisher, authors, institutions, countries, WoS categories, funding information, and citation counts, and summarized the corpus using descriptive statistics.    Results: Of 416 records, 331 met eligibility. Output rose after 2014, peaking in 2016 and 2021 (n=36 each) and 2022 (n=39). All included articles were published in English per the inclusion criteria; 45.9% were open access. As of January 1, 2024, total citations were 10,815 (mean 32.7 per article). Publications appeared in 132 journals; Brain Research ranked first (n=16). Elsevier and Springer Nature led publishers. China contributed the most articles (n=273), followed by the United States (n=56) and Japan (n=19). Across 38 WoS categories, Neurosciences and Clinical Neurology predominated. Among 1,406 authors, the most prolific contributors included Chen G., Wang Z., and Zhang J.H. Funding was reported in 299 articles, most frequently from the National Natural Science Foundation of China (n=150), followed by NIH and HHS (n=31 each).    Conclusion: This title-level corpus shows rapidly growing EBI–SAH output with substantial citation impact, driven mainly by China and the United States, and spanning mechanistic and clinical domains.
