Advancements in neuromonitoring for predicting cerebral vasospasm in aneurysmal subarachnoid hemorrhage using near-infrared spectroscopy: an observational study and review of the literature.

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
introductionAneurysmal subarachnoid hemorrhage (aSAH), a severe form of hemorrhagic stroke, poses significant diagnostic and management challenges, particularly in predicting and managing cerebral vasospasm and delayed cerebral ischemia. This study explores the predictive value of near-infrared spectroscopy (NIRS) in high-grade aSAH patients. MATERIAL AND
methodsThis observational study included 16 high-grade aSAH patients treated at a single institution from June 2020 to November 2023. Neuromonitoring incorporated daily transcranial Doppler and continuous NIRS, alongside routine computed tomography perfusion. The primary endpoint was the occurrence of major cerebral vasospasms detected by digital subtraction angiography preceded by a decrease in regional oxygen saturation as indicated by NIRS.
resultsAmong the participants, vasospasms were most prevalent in the internal carotid artery (56.3%), followed by the middle cerebral artery (50%). NIRS detected alterations in 43.8% of the cohort, with 25% occurring before vasospasm onset. A correlation between early NIRS alterations and specific vasospasm locations was identified.
conclusionsConclusions: While NIRS shows potential for continuous, non-invasive monitoring of cerebral oxygenation, its utility in predicting vasospasms is limited. The findings underscore the importance of integrating NIRS with other neuromonitoring modalities to enhance predictive accuracy and patient management in aSAH. Large-scale studies are necessary to establish protocols and intervention thresholds.
