Hemodynamics changes during the intubation periods with the two laryngoscopes. Mean arterial pressure (MAP, upper) and heart rate (lower) are shown. The values increase at the time of intubation and return to baseline at 3 min after intubation with the exception of the GlideScope group. The data are presented as means ± SDs. Baseline: prior to intubation; Intubation: at the time of intubation; 3 min: 3 min after intubation. *P < 0.05, compared with baseline; ^ΔP < 0.01, for the comparison between two groups.
