Changes in HR, MAP, SBP and BIS during the endotracheal intubation. Data are presented as mean, CI confidence interval. T: Time points. T0: enter the operating room; T1: before induction; T2: baseline; T3: immediate of intubation; T4: the maximum value after intubation; T5: 1Â min after intubation; T6:2Â min after intubation; T7: 3Â min after intubation. Time points do not represent the sequence of events. *P < 0. 05 when compared between the groups
