| 摘 要： | 目的：探讨胎儿脑和脐血流预测胎儿生长迟缓的作用。方法：应用双功能多普勒超声检测８４例正常妊娠晚期胎儿和３１例胎儿生长迟缓（ＩＵＧＲ）胎儿脐动脉（ＵＡ）搏动指数（ＰＩ）、大脑中动脉（ＭＣＡ）ＰＩ和ＵＡＰＩ／ＭＣＡＰＩ比值。结果：ＩＵＧＲ胎儿ＭＣＡＰＩ显著小于正常胎儿（Ｐ＜０．０１），ＵＡＰＩ和ＵＡＰＩ／ＭＣＡＰＩ比值明显高于正常胎儿（Ｐ＜０．０１）。以二个标准差作为截止点水平，ＭＣＡＰＩ、ＵＡＰＩ和ＵＡＰＩ／ＭＣＡＰＩ比值预测ＩＵＧＲ的敏感性分别为８０．６４％、７０．９６％和８７．０９％；特异性分别为９４．０５％、８８．９０％和９７．６１％。结论：ＵＡＰＩ和ＭＣＡＰＩ可预测ＩＵＧＲ。
