"Scientific trends of pharmacological methods in labor pain management: bibliometric analysis of epidural, spinal, and other approaches, 2000-2025".
Review in Revista da Associacao Medica Brasileira (1992), 2026. 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
objectiveLabor pain management is a fundamental aspect of obstetric care. Pharmacological methods such as epidural and spinal analgesia are widely preferred in this process, but scientific productivity and trends regarding these approaches have not been sufficiently analyzed. The aim of this study was to provide a bibliometric assessment of the scientific profile in the field of pharmacological obstetric pain management by examining the literature published between 2000 and 2025.
methodsWeb of Science Core Collection database was searched with the keywords "labour pain management," "childbirth pain," "labour analgesia," "obstetric analgesia," "epidural analgesia," "spinal anaesthesia," "pharmacological analgesia," and "pharmacological pain management." The distribution of publications by years, contributions by countries and institutions, collaboration networks, most cited studies, and journal distribution were analyzed.
resultsA total of 1,606 publications were analyzed. Scientific productivity in the field of epidural and spinal analgesia has increased significantly, especially after 2019. The vast majority of publications are based in the USA, the UK, and China. The most cited publications focus on the efficacy, safety, and complications of pharmacological methods. Collaboration maps indicate a multidisciplinary and international research network.
conclusionPharmacological labor pain management literature reflects the current trends that guide clinical obstetric practice. When developing guidelines for the use of these methods in midwifery and obstetrics, qualitative aspects as well as the quantitative increase in the literature should be taken into account. Our study sheds light on the research gaps in this field and the research areas that can be focused on for the future.
