Monitoring of cerebral autoregulation during major surgery in adults, including cardiac surgery: mechanisms, anesthetic impacts, and clinical applications.
Review in Frontiers in medicine, 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
Background: Cerebral autoregulation (CA) is a critical neuroprotective mechanism that maintains stable cerebral blood flow across varying blood pressure (BP). The perioperative period disrupts CA through anesthetic and surgical interventions, yet standardized monitoring protocols are lacking in adult major surgery. Findings: Evidence demonstrates that anesthetic choice significantly modulates CA. Total intravenous anesthesia better preserves autoregulation compared to volatile agents. Surgical factors-including cardiopulmonary bypass, patient positioning, and procedure duration-further influence CA integrity. Near-infrared spectroscopy-derived cerebral oximetry index (COx) provides the most practical approach for routine perioperative CA monitoring. Personalized BP management based on autoregulation thresholds optimizes cerebral perfusion and reduces neurological complications, as shown in cardiac surgery. Conclusion: Integrating CA-preserving anesthetic techniques with real-time monitoring represents a promising strategy for precision perioperative care. Future validation through large-scale randomized trials is essential to establish standardized protocols and confirm effects on patient-centered outcomes.
