目的：探讨脐动脉多普勒正常的小于胎龄儿引产后胎儿状态不稳定及新生儿酸中毒的预测价值。方法：对210例脐动脉多普勒正常的足月小胎龄儿和210例正常对照进行引产前胎儿脑血流参数的测定，包括脑组织血流灌注分数、脑胎盘比率和大脑中动脉搏动指数。结果：小于胎龄儿的剖宫产率明显高于对照组(P<0.0 5)。
OBJECTIVE: To estimate the value of fetal brain Doppler in predicting the risk of cesarean delivery for nonreassuring fetal status and neonatal acidosis after labor induction in small-for-gestational-age fetuses with normal umbilical artery Doppler.METHODS: Fetal brain Doppler parameters, including cerebral tissue perfusion measured by fractional moving blood volume, cerebroplacental ratio, and middle cerebral artery pulsatility index, were evaluated before labor induction in a cohort of 210 term small-for-gestational-age fetuses with normal umbilical artery Doppler and 210 control participants matched by gestational age. The value of the cerebral Doppler indices to predict the risk of cesarean delivery, cesarean delivery for nonreassuring fetal status, and neonatal acidosis was analyzed.RESULTS: Overall, small-for-gestational-age fetuses showed a significant higher incidence of cesarean delivery (37.6% compared with 19.5%, P
