Observational Examination of Cerebral Perfusion Changes in Patients Diagnosed with Sepsis Using Transcranial Doppler Ultrasonography.
Article in Tanaffos, 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
Background: Sepsis-associated Brain Dysfunction (SABD) affects over 70% of septic patients, often manifesting early and increasing the risk of neurological sequelae if undiagnosed. Transcranial Doppler (TCD) ultrasonography is a noninvasive, bedside method to assess Cerebral Blood Flow (CBF). This study evaluates temporal changes in middle cerebral artery blood flow in septic patients using Pulsatility Index (PI), Resistance Index (RI), and CBFi at 0, 6, 24, and 48 hours. Materials and Methods: Forty-seven septic patients admitted to the Bursa Uludag University Intensive Care Unit were prospectively studied. Demographic data, comorbidities, Sequential Organ Failure Assessment (SOFA), Acute Physiology and Chronic Health Evaluation (APACHE) II scores, vital signs, laboratory parameters, and TCD measurements (PI, RI, CBFi) were recorded at baseline, 6, 24, and 48 hours. Results: No statistically significant changes were observed in PI, RI, or CBFi at 6, 24, or 48 hours compared to baseline (p>0.05), though slight increases in PI (2.13%) and CBFi (16.99%) were noted at 48 hours. A significant difference in PI was found at 48 hours in patients receiving vasoactive drugs (p<0.05), and in RI at 6 hours in those receiving sedoanalgesics (p<0.05). Stable systemic hemodynamics were maintained using advanced monitoring. Conclusion: In septic patients with optimized hemodynamic management, cerebrovascular resistance and perfusion indices (PI, RI, CBFi) remain largely stable within 48 hours, suggesting effective autoregulation. TCD shows potential as a tool to monitor cerebral perfusion and guide therapy in sepsis, warranting further research.
