WebMar 24, 2024 · Nevertheless, hyperperfusion changes appear to occur more frequently when imaging ensues within 3 h after the seizures [ 2, 3 ]. In some cases, postictal perfusion changes are uni-hemispheric, mostly contralateral to the clinical deficits. These changes have been reported as hemispheric hypoperfusion [ 4, 5] or hyperperfusion [ 3, 6 ]. WebAlthough ephedrine increases blood pressure and CBF, it has also been reported to increase BIS values directly. 20 Similar to cerebral oximetry, BIS and other processed EEG monitors analyze EEG signals from the frontal …
