Ligation of the internal jugular vein increased regional cerebral oxygen saturation but decreased the bispectral index in a 72-year-old man: a case report
Abstract Regional cerebral oxygen saturation (rSO2) and the bispectral index (BIS) are used to detect cerebral perfusion abnormalities. However, whether rSO2 and BIS values change during ligation of the internal jugular vein (IJV) is unknown. We report a case in which BIS values were decreased, desp...
