Fig. 1From: Electroencephalogram evaluation of accidental cerebral congestion during unexpected superior vena cava clamping: a case reportClinical course. Black line indicates mean atrial pressure (MAP). The gray line indicates the state entropy (SE). The gray dotted line indicates the burst suppression ratio (BSR). The black arrow indicates phlebotomy. During cerebral congestion, the gray area indicates superior vena cava (SVC) clamping. Increases in SE and decreases in BSR were observed two times after the phlebotomy procedures. TCI, target-controlled infusionBack to article page
