Figure 1. Fetal lingual and femoral blood pressures and heart rate.

Figure 1

The lingual and femoral arterial blood pressures and heart rate of fetal sheep before, during and after a 10-minute period of brachiocephalic occlusion (indicated by hatched areas) with (open circles, n = 14) or without (closed circles, n = 4) pre-treatment with 3mg/kg ketamine. Data are presented as mean values ± SE. Baseline is considered to be at −5 minutes. A. a P < 0.001 During occlusion, lingual pressure significantly decreased from baseline in both groups. * P < 0.05 Significant interaction of time × group. B. b P < 0.001 Femoral pressure increased significantly from baseline during occlusion in both groups. * P < 0.05 Significant interaction of time ×group. C. c P < 0.001 Fetal heart rate significantly increased from baseline during and after occlusion in control fetuses. d P < 0.05 Heart rate increased above baseline in ketamine-treated fetuses. * P < 0.05 Significant interaction of time × group.
