[Bibliometric analysis of the original articles published in the Revista Española de Anesthesiología y Renimación in 10 years (1987-1996)].
OBJECTIVE
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.


METHODS
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.


RESULTS
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).


CONCLUSIONS
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.
