Figure 1

Systolic blood pressure and diastolic blood pressure by group. Open circles indicate the ephedrine group, and solid circles indicate the control group. Data are mean with standard error of mean, *P < 0.05 (between groups), fP < 0.05 (within group from Pre-in), Pre-in = pre-induction, Post-in = post-induction 2.5 min, T0, 15, 30, …, 120 = at 0, 15, 30, …, 120 min after intubation.
