Fig. 2. Doppler sonography evaluation of middle cerebral artery (MCA) function following maternal gastric infusion of either control- or alcohol-containing fluid.
A. Snapshots showing fetal MCA blood flow velocity before and 120 min following maternal gastric infusion of control (two left panels) vs. alcohol-containing fluid (two right panels). B. Averaged data showing a statistically significant drop in fetal cerebral artery peak systolic velocity following maternal gastric infusion of alcohol-containing but not control fluid. Maternal alcohol infusion does not affect gestational age-dependent increase in peak systolic velocity (panel on the right). In B and C, data at each exposure were compared using independent paired t tests. **Significantly different from pre-exposure level in corresponding exposure episode, p < 0.01. C. Averaged data showing lack of statistically significant difference in resistive index of fetal cerebral arteries from control- vs. alcohol-infused mothers. Control-infused: N = 3; alcohol-infused: N = 4.
