Research Trends and Knowledge Mapping of Opioid-Free Anesthesia: A Global Bibliometric Analysis.
Article in Journal of multidisciplinary healthcare, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Purpose: Opioid-free anesthesia (OFA), as a potential anesthetic strategy, can provide better clinical outcomes for surgical patients while avoiding opioid-related adverse side effects. However, the current knowledge framework and research progress in OFA have not yet been systematically reviewed or comprehensively analyzed. This study aims to employ bibliometric methods to thoroughly explore research trends, hotspots, and developmental directions in this field. Methods: This study retrieved opioid-free anesthesia-related literature published between 1980 and 2024 from the Web of Science Core Collection database. Through systematic analysis of publications, countries, institutions, authors, journals, references, and keywords, combined with bibliometric visualization using software such as Citespace, VOSviewer, and Bibliometrix, this study comprehensively reveals the research status and developmental trends in this field. Results: OFA research demonstrates a significant growth trend, with a sharp increase in publications over the past decade, reaching 2,219 citations in 2024 alone. The United States leads globally with 291 publications (7,896 citations) yet exhibits low international collaboration network density (0.008). Research hotspots evolve into three phases: early-stage focus on basic anesthetic protocols, mid-stage shift toward perioperative management optimization, and recent emphasis on clinical outcome improvement. Keyword analysis identified four core themes: anesthetic agents and protocols, perioperative management, and analgesic strategy optimization. Conclusion: OFA research is in a phase of rapid development but requires enhanced international collaboration and clinical translation. Future efforts should focus on developing personalized OFA protocols, investigating long-term outcomes, and establishing multicenter research networks to provide higher-quality evidence for clinical practice.
