To describe the original research articles published in Revista Española De Anestesiología y Reanimación (REAR) from 1987 through 1996, as well as to characterize the citations included in those articles.
The 299 articles published as original research in REAR over the past 10 years (1987 through 1996) were analyzed. The bibliographic aspects examined were coauthorship (authors/paper index), citations per article, isolation in function of language of publication of references, degree of obsolescence of articles based on year of references cited ("half-life"), self-citation and degree of dispersion of citations.
The authors/paper index was 5.16 +/- 1.62. No statistically significant difference was found in number of authors over the 10-year study period. Mean number of references cited per article was 24.05 +/- 12.02. We found statistically significant differences for 1993 and the period 1987 to 1988, and 1994 and the year 1987 (p < 0.001). The "half-life" of articles was 6 when analyzing on a year-by-year basis; this index ranged from 5.5 to 7, with no significant annual differences. REAR articles accounted for 4.02% of all citations. English was the most frequent language of cited publications, with 6,240 references (86.8%), followed by Spanish with 621 (8.64%), French with 223 (3.1%) and German with 74 (1.03%). Of the 7,191 references analyzed, 6,447 (89.65%) were of scientific journals. Books are the second most commonly cited type of document, with 623 (8.66%) citations. Analyzing journals cited 25 or more times, we found that 74.19% of the articles (4,783/6,447) had been published in 5.3% of the journals (36/678). Seven journals of anesthesia, which represented 1.03% of all journals (7/678) appeared in 52.81% of references of this type (3,405/6,447).
The number of authors of original research articles published in REAR in the last 10 years was high. Spanish authors in anesthesiology cite mainly literature in English; use up-to-date sources of information, mainly journals; and take a large proportion of information from a small number of journals, which are those of greatest international impact in our specialty.
描述1987年至1996年发表于《西班牙麻醉与复苏杂志》（REAR）的原创研究文章，并对这些文章中的参考文献进行特征分析。
分析了过去10年（1987年至1996年）在REAR上发表的299篇原创研究文章。考察的文献学方面包括合著情况（作者/论文指数）、每篇文章的参考文献数量、参考文献发表语言的分布、根据引用参考文献年份计算的文章陈旧程度（“半衰期”）、自引情况以及参考文献的分散程度。
作者/论文指数为5.16±1.62。在10年的研究期间，作者数量未发现统计学上的显著差异。每篇文章引用参考文献的平均数量为24.05±12.02。我们发现1993年与1987年至1988年期间、1994年与1987年存在统计学上的显著差异（p<0.001）。逐年分析时，文章的“半衰期”为6年；该指数在5.5至7之间，年度差异不显著。REAR文章占所有参考文献的4.02%。英语是被引用出版物中最常用的语言，有6240条参考文献（86.8%），其次是西班牙语，有621条（8.64%），法语有223条（3.1%），德语有74条（1.03%）。在分析的7191条参考文献中，6447条（89.65%）来自科学期刊。书籍是第二常见的被引用文献类型，有623条（8.66%）。分析被引用25次及以上的期刊时，我们发现74.19%的文章（4783/6447）发表于5.3%的期刊（36/678）。7种麻醉学期刊占所有期刊的1.03%（7/678），却出现在此类参考文献的52.81%中（3405/6447）。
过去10年发表在REAR上的原创研究文章的作者数量较多。西班牙麻醉学领域的作者主要引用英文文献；使用最新的信息来源，主要是期刊；并且大量信息来自少数几本期刊，这些期刊在我们专业领域具有最大的国际影响力。
