Reconceptualizing regional anesthesia as a systemic modulator: a hypothesis-driven gut-brain axis perspective.
Article in Frontiers in neuroscience, 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
Traditionally, regional anesthesia has been considered a local analgesic technique with benefits limited to the site of blockade. However, emerging preclinical and clinical evidence indicates that it may produce systemic effects by modulating the gut-brain axis. The gut-brain axis is a bidirectional regulatory system that integrates neural, immune, endocrine, and microbial signaling and is crucial for managing perioperative stress, inflammation, and physiological balance. This perspective article examines how regional anesthesia influences the gut-brain axis through several interconnected pathways, including neural modulation, immune regulation, endocrine effects, and indirect alterations in gut microbiota. We argue for reconceptualizing regional anesthesia as a systemic modulator and discuss its potential applications in perioperative recovery and chronic disease management. We conclude by calling for interdisciplinary research and mechanism-focused clinical trials to integrate this perspective into a more holistic model of perioperative medicine.
