Effect of the artificial rupture of the membranes on the blood flow in descending aorta and the umbilical artery of the fetus

Effect of the artificial rupture of the membranes on the blood flow in descending aorta and the umbilical artery of the fetus

Doppler velocity waveform analysis from descending aortic and umbilical artery signals was performed in 30 term pregnancies without complications before and after artificial rupture of the membranes (AROM). There was no significant difference between the umbilical artery and descending aorta S/D ratios, during acute changes in amniotic fluid volume.
