We performed a study in Doppler sonography in pregnant patients with hypotension compared with women in pregnancy with normal blood pressure. The flow was measured in the foetal aorta, the umbilical artery such as in the A. arcuate and A. cerebri media. Low blood pressure is followed by decreased uteroplacental perfusion. That means a haemodynamic danger for the foetus reflected in significantly increased flow parameters. The low central flow indices show a centralisation of the foetal blood circulating system. These findings describe the importance of hypotension as a risk of pregnancy we have to observe carefully.
我们对妊娠合并低血压患者进行了一项多普勒超声研究，并与血压正常的妊娠女性进行了比较。测量了胎儿主动脉、脐动脉（如弓形动脉和大脑中动脉）的血流。低血压会导致子宫胎盘灌注减少。这意味着对胎儿存在血液动力学危险，表现为血流参数显著增加。低中心血流指数表明胎儿血液循环系统发生了集中化。这些发现说明了低血压作为一种妊娠风险的重要性，我们必须仔细观察。
