A prospective comparative study to assess the effect of maternal smoking at 37 weeks on Doppler flow velocity waveforms as well as foetal birth weight and placental weight

Maternal smoking is known to have adverse effects on the foetus. This study aimed to evaluate the effects of maternal smoking during pregnancy on arterial blood flow velocities in the foetal-placental-maternal circulation, and the pathophysiological relationship with placental and foetal birth weigh...

Description
Summary:Maternal smoking is known to have adverse effects on the foetus. This study aimed to evaluate the effects of maternal smoking during pregnancy on arterial blood flow velocities in the foetal-placental-maternal circulation, and the pathophysiological relationship with placental and foetal birth weight. A total of 148 singleton pregnancies in 59 smokers and 89 non-smoking controls were examined during the 37th week of gestation. Blood flow in the maternal uterine, foetal umbilical and middle cerebral arteries was analysed with Doppler ultrasonography. Statistically significant differences in Doppler waveforms were detected in the foetal umbilical artery (UmbA) (p  0.05). Both infant birthweight and placental weight were significantly decreased by maternal smoking (p
