Abstract: BACKGROUND: The expansion of science has resulted in an
increased information flow and in an exponentially growing number of
connections between knowledge in different research fields. In this study,
we used methods of scientometric analysis to obtain a conceptual network
that forms the structure of active scientific research fields in
anesthesia.
METHODS: We extracted from the Web of Science (R) (Institute for
Scientific Information) all original articles (n = 3275) including their
references (n = 79,972) that appeared in 2003 in all 23 journals listed in
the Institute for Scientific Information journal Citation Reports' under
the subject heading "Anesthesiology." After identification of highly cited
references (>= 5), pairs of co-cited references were created and grouped
into uniformly structured clusters of documents using a single linkage and
variable level clustering method. In addition, for each such cluster of
documents, we identified corresponding front papers published in 2003,
each of which co-cited at least two documents of the cluster core. Active
anesthetic research fields were then named by examining the titles of the
documents in both the established clusters and in their corresponding
front papers. These research fields were sorted according to the
proportion of recent documents in their cluster core (immediacy index) and
were further analyzed.
RESULTS: Forty-six current anesthetic research fields were identified. The
research field named "ProSeal laryngeal mask airway" showed the highest
immediacy index (100%) whereas the research fields "Experimental models of
neuropathic pain" and "Volatile anesthetic-induced cardioprotection"
exhibited the highest level of co-citation strength (level 9). The
research field with the largest cluster core, containing 12 homogeneous
papers, was "Postoperative nausea and vomiting." The journal Anesthesia &
Analgesia published most front papers while Anesthesiology published most
of the fundamental documents used as references in the front papers.
CONCLUSIONS: Using co-citation analysis, we identified distinct homogenous
clusters of highly cited documents representing 46 active current
anesthetic research fields and determined multiple nets of knowledge among
them.
