Rosenthal ES, et al. - In this analysis, the researchers prospectively evaluated the accuracy of continuous electroencephalographic (cEEG) for predicting delayed cerebral ischemia (DCI), following the Standards for Reporting Diagnostic Accuracy Studies. For this investigation, they prospectively performed cEEG in nontraumatic, high-grade subarachnoid hemorrhage (SAH) patients at a single institution. Results revealed that 103 of 227 consecutive patients were eligible and underwent cEEG monitoring. The study findings suggested that cEEG accurately predicts DCI following SAH and could help target therapies to patients at highest risk of secondary brain injury.
