The aim of this study was to analyse publication trends from the anaesthetic literature of the G-20 countries. We performed a literature search in Medline to identify articles related to anaesthetic departments published between 2001 and 2015, by specific G-20 countries according to the affiliation field of the authors, and to three time periods 2001-2005, 2006-2010 and 2011-2015. The number of articles, number of original articles (vs. reviews, editorials or correspondence), articles per million inhabitants, and citations per article were analysed. In total, 96,920 articles were published between 2001 and 2015 in 74 anaesthetic and in 4117 non-anaesthetic journals, with an increase of +104% absolute (i.e. from 23,028 in 2001-05 to 46,887 articles ìn 2010-15) and +85% as articles per million inhabitants. Similarly, the number of original articles increased by 21%, but the anaesthetic specialty's share of original articles (as a proportion of total articles in biomedicine) decreased from 31% in 2001-2005 to 19% in 2011-2015 (-38%). The USA published most articles (2011-15 16,016; 31% of total), second came the EU as a whole and third Japan (from 2001 to 2005) or Germany (2006-2010) until 2011-2015 when China took over the third rank. In 2011-2015, Canada published most articles per million inhabitants (68.7 articles/million inhabitants). China and India exhibited the most publication growth 11- and 9-fold, respectively, and are now among the top five countries for the number of published articles.
本研究旨在分析 G20 国家麻醉学文献的发表趋势。我们在 Medline 中进行了文献检索，以确定根据作者所属机构确定的 2001 年至 2015 年间与麻醉科相关的文章，并确定了三个时期：2001-2005 年、2006-2010 年和 2011-2015 年。分析了文章数量、原始文章数量（与综述、社论或通信相比）、每百万居民的文章数量和每篇文章的引用次数。2001 年至 2015 年间，在 74 种麻醉学期刊和 4117 种非麻醉学期刊上共发表了 96920 篇文章，绝对增长了 +104%（即从 2001-05 年的 23028 篇增加到 2010-15 年的 46887 篇），按每百万居民计算的文章数量增长了+85%。同样，原始文章的数量增加了 21%，但麻醉专业原始文章的比例（占生物医学总文章的比例）从 2001-2005 年的 31%下降到 2011-2015 年的 19%-38%。美国发表的文章最多（2011-15 年 16016 篇；占总数的 31%），其次是欧盟整体，第三是日本（2001-2005 年）或德国（2006-2010 年），直到 2011-2015 年中国取代第三位。2011-2015 年，加拿大每百万居民发表的文章最多（68.7 篇/百万居民）。中国和印度的发表量增长最快，分别增长了 11 倍和 9 倍，现已成为发表文章数量最多的前五个国家之一。
