Continuous variables are presented as mean (standard deviation). Compared with T0, rSO2 in group RF was increased at T2–T4 but decreased at T5–T8, while compared with T0, rSO2 in group GDT was increased at T1–T8. Compared with T0, MAP, CI, and BIS in both groups were decreased at T1–T8. Compared with T0, HR in both groups was decreased at T1–T7 but increased at T8 (*P < 0.05). Compared with group RF, intraoperative rSO2 and MAP values were increased at T5–T8 in group GDT (**P < 0.05) (a, c); compared with group RF, intraoperative CI and HR values were increased at T6–T8 in group GDT (**P < 0.05) (b, d). T0: 5 min before the induction of anesthesia; T1: 5 min after induction of anesthesia; T2: start of surgery; T3: 30 min after the start of surgery; T4: 60 min after the start of surgery; T5: 90 min after the start of surgery; T6: 120 min after the start of surgery; T7: end of surgery; T8: 5 min after extubation. MAP mean arterial pressure, rSO2 regional cerebral oxygen saturation, HR heart rate, CI cardiac index, BIS bispectral index
