Intervillous blood flow (IVBF) was measured intravenously with a new quantitative 133Xe method in 50 normal and 74 complicated late pregnancies between the 35th and 42nd weeks. The distribution of individual flow rates seemed to be fairly wide in both the normal and the pathological groups. The mean rate of IVBF in normal pregnancies was 140 ml/100 ml of intervillous space/min. The lowest mean flow values were observed in pregnancies complicated by diabetes mellitus (class B-E), cholestasis of pregnancy and severe pre-eclampsia, a highly significant difference (p less than 0.001) from the mean IVBF observed in normal pregnancies. The significance of the results in the different groups has been discussed in detail. This method may open up a new diagnostic area in the management of high-risk pregnancies.
采用一种新的定量¹³³Xe方法对50例孕35至42周的正常晚期妊娠孕妇和74例并发晚期妊娠孕妇进行了静脉内绒毛间隙血流（IVBF）测定。正常组和病理组个体流速分布似乎都相当广泛。正常妊娠时IVBF的平均速率为140ml/100ml绒毛间隙/分钟。在并发糖尿病（B - E级）、妊娠胆汁淤积症和重度子痫前期的妊娠中观察到最低平均血流值，与正常妊娠中观察到的IVBF平均值相比有极显著差异（p＜0.001）。已详细讨论了不同组结果的意义。该方法可能为高危妊娠的管理开辟一个新的诊断领域。
