Abstract：Fetal intrauterine anoxia is one of the important causes of perinatal death. Prenatal fetal hypoxia can be effectively predicted, which is great significance to reduce perinatal mortality. Combined detection of fetal doppler blood flow parameters,including the umbilical artery, middle cerebral artery, renal artery, venous catheter, abdominal umbilical vein, and so on, can reflect the abnormal state of fetal organs, accurately assess fetal intrauterine hypoxia status and improve the diagnostic rate of fetal distress. The ratio of cerebral artery and umbilical artery pulsation index was used to eliminate the common interference factors, which ruled out the influence of the base fluctuation, and was affected by the change of blood perfusion impedance. Cerebroplacental rate can reflect the distribution of blood flow of fetal body better than a single vessel, for early evaluation of placenta fetal blood circulation changes. As for a more comprehensive evaluation of intrauterine hypoxia degree, it can predict adverse outcomes of pregnancy earlier, timely detect the abnormal, timely intervention, improve the perinatal quality and have more clinical value. It is worth to be popularized in clinical application.
