2. Fig 1
The per cent changes of systolic blood pressure (SBP) during the observation in the four groups. Children in Groups 1, 2, 3, and 4 received normal saline, sufentanil 0.1 μg kg−1, sufentanil 0.2 μg kg−1, and sufentanil 0.3 μg kg−1, respectively. Points were means. *P < 0.05 compared with Group 1, #P < 0.05 compared with Group 2, †P < 0.05 compared with Group 3.

The per cent changes of heart rate (HR) during the observation in the four groups. Children in Groups 1, 2, 3, and 4 received normal saline, sufentanil 0.1 μg kg−1, sufentanil 0.2 μg kg−1, and sufentanil 0.3 μg kg−1, respectively. Points were means. *P < 0.05 compared with Group 1, #P < 0.05 compared with Group 2, †P < 0.05 compared with Group 3.

The incidences of SBP and HR per cent changes >30% of baseline values during the observation in the four groups. Children in Groups 1, 2, 3, and 4 received normal saline, sufentanil 0.1 μg kg−1, sufentanil 0.2 μg kg−1, and sufentanil 0.3 μg kg−1, respectively. Note: the incidences of SBP and HR per cent increases >30% of baseline values during the observation in Group 4 were 0%. *P < 0.05 compared with Group 1; #P < 0.05 compared with Group 2.
