The 100 top-cited studies on postoperative hyperalgesia in the last 30 years: a bibliometric analysis

Abstract

Background: In recent years, the issue of postoperative pain has raised wide concern in the medical community. Postoperative hyperalgesia (POH), as the primary etiology of pain, has been extensively studied and numerous articles have been published on this topic; however, no comprehensive bibliometric review of POH publications has been conducted. Thus, we aimed to examine the 100 top-cited reports on POH and summarize their key characteristics.Methods: Published studies on POH were retrieved from the Web of Science Core Collection (WoSCC) using the search terms "postoperative hyperalgesia". All papers published since 1980 were searched. The search results were sorted by the frequency of the total citations, and 2 reviewers independently skimmed the abstracts and full texts to identify the 100 top-cited reports. After the 100 top-cited papers were identified, the following data were extracted by the two reviewers: the title, surname(s) of the author(s), name of the first author, publication year, country of origin, article type, institutional affiliations, keywords, source journal, and impact factor (IF) of the journal. Results:The initial search returned 1,747 papers, published in 466 journals that originated from 1,679 institutions in 48 countries. The 100 top-cited reports received 21,454 citations. The USA was the most cited and most productive country, contributing nearly half of the 100 top-cited papers. The numbers of studies on POH have trended upward and continue to increase each year.Conclusions: An analysis of the 100 top-cited studies on POH provided a better guidance for ongoing researches. The prominent keywords "opioid-induced hyperalgesia", especially "remifentanil", is still on top of POH research area. Nevertheless, the mechanism of POH is intricate and unclear, which is crucial to conduct further studies and find some new interventions.

Electric Vehicle Supply Chain Management: A Bibliometric and Systematic Review

“…They were chosen to analyse trends related to cooperation and subjects and to assist further studies on journal selection. The indicators included were (a) partnerships between countries [13,14]; (b) co-occurrence of the authors' keywords [13,15]; (c) publications per year [13,[15][16][17]; (d) publications by country [13,15,16]; (e) impact factor of journals [15,18]; and (f) areas of research [17].…”

Thirty-year survey of bibliometrics used in the research literature of pain: Analysis, evolution, and pitfalls

“…Among the various B/P studies, a dozen or so were mainly aimed at investigating the pain literature through citation analysis as indicated in their titles ("Top-cited articles in …" or "Most frequently cited papers in …"). Two studies considered all papers in the pain-related literature (16,47); others were restricted to literatures of specific pain such as fibromyalgia (76,91), neuropathic pain (116), back pain (58,61), postoperative hyperalgesia (122), headache (68,120) trigeminal pain (72); and one study combined the literatures of pain and depression (84).…”

“…( 4) The last parameter specifies if the B/P studies highlight pain and its management or neither. Most of the B/P studies do not analysis the pain literature to this level of detail (116,122); but, when this is the case, studies on the effects of acupuncture on pain dominates (n = 17), followed by studies involving drugs and analgesics (n = 12). Studies including other therapeutics such as alternative medicines (112), or complementary therapeutics (32) were also found.…”
