The aim of this study is to identify research directions focused on epidural hematoma (EDHs) from past to present using bibliometric approaches, uncover current research trends through keyword analyses, delineate global productivity, and identify impactful studies through citation analyses. The study obtained 1785 articles related to EDH published between January 1, 1980, and December 31, 2023, from the Web of Science database, and comprehensive analyses were conducted using various bibliometric and statistical approaches. These analyses include citation and co-citation analyses, trend keyword analysis, multiple correspondence analysis, thematic evolution analysis, and various other bibliometric analyses. The bibliometric analyses were performed using Biblioshiny and VOSviewer. The top 3 journals contributing the most to the literature were Acta Neurochirurgica (n = 56, 3.1%), British Journal of Neurosurgery (48, 2.6%), and Neurosurgery (47, 2.6%). According to the h-index, the most influential top 3 journals were Neurosurgery (h = 27), Acta Neurochirurgica (h = 23), and Surgical Neurology (h = 21). Based on the m-index, the most influential top 3 journals were World Neurosurgery (m = 0.9), Medicine (m = 0.63), and Neurosurgery (m = 0.6). The most active country was the United States of America (n = 593), the most active author was Mahapatra AK (n = 10), and the most active institution was Harvard University (n = 25). Research interest in EDH has evolved over time, with notable increases in publication trends in 1968, 1982, and 1988, peaking in 1996 and 2004. Bibliometric analyses indicate that key topics such as spinal EDH, head injuries, magnetic resonance imaging, spontaneous spinal EDH, computed tomography, spine, complications, epidural, anticoagulants, pediatric cases, and trauma have stood out in EDH research. Trend analysis findings have shown an increasing focus on specific areas such as clinical management approaches, treatment methods, postoperative complications, risk factors, pediatric cases, as well as specific conditions like paralysis and cauda equina syndrome. Multiple correspondence analysis identified 6 core research dimensions, focusing on acute trauma management, surgical interventions, complications management, risk assessment, surgical outcomes, and incidence analysis.
本研究的目的是运用文献计量学方法，确定从过去到现在聚焦于硬膜外血肿（EDH）的研究方向，通过关键词分析揭示当前的研究趋势，描绘全球研究产出，并通过引文分析识别有影响力的研究。该研究从科学网数据库中获取了1980年1月1日至2023年12月31日期间发表的1785篇与EDH相关的文章，并运用各种文献计量学和统计方法进行了全面分析。这些分析包括引文和共被引分析、趋势关键词分析、多重对应分析、主题演变分析以及其他各种文献计量学分析。文献计量学分析使用了Biblioshiny和VOSviewer软件。对该领域文献贡献最大的前3本期刊分别是《神经外科学文献》（n = 56，3.1%）、《英国神经外科学杂志》（48，2.6%）和《神经外科学》（47，2.6%）。根据h指数，最具影响力的前3本期刊分别是《神经外科学》（h = 27）、《神经外科学文献》（h = 23）和《外科神经学》（h = 21）。基于m指数，最具影响力的前3本期刊分别是《世界神经外科学》（m = 0.9）、《医学》（m = 0.63）和《神经外科学》（m = 0.6）。最活跃的国家是美国（n = 593），最活跃的作者是Mahapatra AK（n = 10），最活跃的机构是哈佛大学（n = 25）。对EDH的研究兴趣随时间而演变，在1968年、1982年和1988年发表趋势显著增加，在1996年和2004年达到峰值。文献计量学分析表明，诸如脊柱硬膜外血肿、头部损伤、磁共振成像、自发性脊柱硬膜外血肿、计算机断层扫描、脊柱、并发症、硬膜外、抗凝剂、儿科病例和创伤等关键主题在EDH研究中尤为突出。趋势分析结果显示，研究越来越关注临床管理方法、治疗手段、术后并发症、危险因素、儿科病例等特定领域，以及诸如瘫痪和马尾综合征等特定病症。多重对应分析确定了6个核心研究维度，重点关注急性创伤管理、手术干预、并发症管理、风险评估、手术结果和发病率分析。
