Table 1 Additional data of BIS values after ligation of the IJV. Changes in suppression ratio (SR), spectral edge frequency 95 (SEF95), electromyography (EMG) and signal quality index (SQI) 10 min after the internal jugular vein (IJV) ligation are shown

From: 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
