Effect of fetal alcohol exposure on umbilical artery Doppler indices. A, Average changes in pulsatility index (PI) by repeated alcohol exposure. Data are normalized to the values that were obtained immediately before the infusion of control or alcohol-containing drink. Zero level represents no change in measured parameter as observed at 120 minutes following the infusion of the assigned drink when compared to preinfusion levels in each group. Changes in the positive direction reflect the average increase in the measured parameter upon drink infusion, whereas changes in the negative direction are equivalent to the average decrease in the measured parameter upon drink infusion. *Statistically significant difference in changes in fetal artery Doppler indices in response to maternal gastric infusion of control versus alcohol-containing solution, P < .05. B, The mean umbilical artery PI throughout the gestation in control versus alcohol-exposed groups.
