Haemodynamics data are presented as the mean ± standard deviation (SD) or standard error of the mean (SEM). Time point: before induction (T0), before superficial anaesthesia (T1), after superficial anaesthesia (T2), before intubation (T3), after intubation (T4), and 1 min after intubation (T5). Compared with Group S and Group D, Group R and Group DR had lower SBP and DBP at T4 and T5 (A: SBP: T4*P = 0.001 and T4*P = 0.002, respectively; T4*P < 0.001 and T4*P = 0.001, respectively, SBP: T5*P < 0.001 and T5*P = 0.015, respectively; T5*P < 0.001 and T5*P < 0.001, respectively. B: DBP: T4*P < 0.001 and T4*P < 0.001, respectively; T4*P < 0.001 and T4*P < 0.001, respectively; DBP: T5*P < 0.001 and T5*P < 0.001, respectively; T5*P < 0.001 and T5*P < 0.001, respectively). Compared with Group S and Group R, Group D and Group DR had a lower HR at T3 (C: HR: T3*P < 0.001 and T3*P < 0.001, respectively; T3*P < 0.001 and T3*P < 0.001, respectively). Moreover, the HR in Group DR was lower than that in the other groups at T4 and T5 (C: HR: T4*P < 0.001, T4*P < 0.001, T4*P < 0.001, respectively; T5*P < 0.001, T5*P < 0.001, T5*P < 0.001, respectively)
