Abstract
Objective:To investigate the value of ductus venosus(DV) and middle cerebral artery(MCA) pulsatility index(PI) and DV-PI/MCA-PI in predicting fetal hypoxia in high-risk in late pregnancy.Method:95 fetuses between 36 and 42 weeks in high-risk(high-risk pregnancy group) and 100 normal fetuses between 36 and 41 weeks(normal pregnancy group) were measured for DV and MCA pulsatility index(PI) by means of color Doppler ultrasonography,and the pulsatility index(PI) ratio was calculated.Fetuses in high-risk were estimated according to the measured normograms for the presence of fetal hypoxia,and the results were evaluated by diagnostic test.Result:Significant differences were found in DV and MCA pulsatility index and pulsatility index ratio betweentwo groups(P<0.01).The sensitivity and specificity of DV and MCA pulsatility index and pulsatility index ratio in predicting fetal hypoxia in high risk fetal were respectively 78%,59%,82%,71%,91% and 90%.Conclusion:DV and MCA pulsatility index ratio is a better indicator than its pulsatility index in predicting fetal hypoxia of fetuses in high-risk pregnancy,and may help in early detection of fetal hypoxia for a diagnosis before fetal distress.关键词
