T0 represents the basic heart rate 10 min before the study. T1, T2 and T3 represent 1 min, 3 min and 5 min after intubation, respectively. Heart rate increased 1 min after intubation in all three groups and increased 3 min after intubation in the C-MAC(D) group. Compared with T0, GlideScope *P < 0.05, C-MAC(D) **P < 0.01, Macintosh **P < 0.01 in T1, C-MAC(D) P < 0.01 in T2
