the Research of the Cerebral Protection Effects of Electroencephalogram (SedLine) During Carotid Endarterectomy

Fragile brain is the most common phenomenon seen in the patients undergoing CEA. The patients with fragile brain have a high incidence of postoperative brain dysfunction. This study intends to apply EEG monitoring (Sedline) to CEA to investigate whether EEG monitoring can reduce the incidence of postoperative neurological complications in CEA patients and improve their prognosis. 220 patients with CEA were randomly divided into 2 groups. Group S \[Sedline monitoring + Transcranial Doppler (TCD) + regional cerebral oxygen saturation (rS02)，n=110\] and group C \[Bispectral index (BIS)/Sedline monitoring + TCD +rSO2,n=110\], recording intraoperative and postoperative conditions, neuropsychology scale assessment, blood examination and imaging examination. The incidence of postoperative neurological complications was compared between the two groups.
