title: The effect of maternal consumption of alcohol on human umbilical artery blood flow.
abstract: A Doppler ultrasound technique was used to measure the effect on human umbilical artery impedance of a single moderate dose of alcohol consumed by mothers compared to a control solution in six normal third-trimester pregnancies. No significant difference in impedance was detected between the alcohol and the control solutions during the subsequent 90 minutes. The results suggest that the known toxicity of maternally ingested alcohol is probably mediated by some mechanism other than a significant acute alteration in fetoplacental blood flow characteristics.
