Fig. 1From: Cerebral oxygen saturation after multiple perioperative influential factors predicts the occurrence of postoperative cognitive dysfunctionScO2 during anesthesia of non-POCD and POCD groups. ScO2 decreased during anesthesia, and ScO2 of POCD group was significantly lower than non-POCD group (P < 0.05). T1-6: before induction, 10 min and 20 min after anesthesia induction, 10 min and 20 min after cement implantation, and 10 min after tourniquet deflationBack to article page
