目的探讨脐动脉血流检测在延期妊娠产前胎盘功能监测中的作用。方法选择2012年5月—2014年10月在浙江大学医学院附属妇产科医院住院分娩的延期妊娠孕妇113人为研究组,同期妊娠40~40+6周的孕妇105人为对照甲组,满37~39+6周的正常妊娠孕妇112人为对照乙组。三组孕妇分娩前进行常规脐动脉血流检测,并追踪三组孕妇的分娩结局和围产儿预后。结果三组脐动脉血流速率在收缩期末和舒张期末的比值(S/D)、搏动指数(PI)和阻力指数(RI)比较,研究组的S/D和PI均高于对照甲、乙组(P<0.017);研究组的RI高于对照乙组(P<0.017);对照甲组PI和RI均高于对照乙组(P<0.017)。三组羊水过少、羊水粪染、巨大儿和围产预后不良的发生率比较,研究组羊水过少发生率高于对照甲、乙组(P<0.017),羊水粪染、巨大儿、围产预后不良发生率均高于对照乙组(P<0.017)。研究组中S/D≥2.5孕妇羊水过少、羊水粪染、胎盘异常、脐带异常及围产儿不良预后发生率均高于S/D<2.5孕妇(P<0.01)。结论脐动脉血流S/D值可作为延期妊娠监测胎盘功能的一项有效指标,当S/D值≥2.5时,应加强产前监护,适时终止妊娠。
Objective To investigate the role of umbilical artery blood flow in the monitoring of prenatal placental function in delayed pregnancy. Methods Select from May 2012 to October 2014 in hospital of obstetrics and gynecology, Zhejiang University School of Medicine obstetrics and gynecology hospital delayed delivery of pregnant women of 113 people for the study group, the same period pregnant 40 ~ 40 + 6 weeks of 105 pregnant women as a control group, over 37 ~ 39 + 6 weeks of normal pregnancy 112 pregnant women control group B. Three groups of pregnant women before routine delivery of umbilical artery blood flow detection, and follow-up of three groups of pregnant women, delivery outcomes and perinatal outcome. Results The S / D and PI of the three groups were higher than those of the control A and B at the end of systolic and diastolic (S / D), pulsatility index (PI) and resistance index (RI) (P <0.017). The RI of the study group was higher than that of the control group B (P <0.017). The PI and RI of the control group were higher than those of the control group B (P <0.017). Three groups of oligohydramnios, meconium-stained amniotic fluid, macrosomia and perinatal poor prognosis, the incidence of oligohydramnios in the study group was higher than the control A, B group (P <0.017), meconium-stained amniotic fluid, giant children, Wai The incidence of adverse outcomes were higher than the control group B (P <0.017). In the study group, oligohydramnios, meconium-stained amniotic fluid, abnormal placenta, abnormal umbilical cord and poor prognosis of perinatal women with S / D≥2.5 were higher than those with S / D <2.5 (P <0.01). Conclusion The S / D value of umbilical artery blood flow can be used as an effective indicator to monitor placental function in delayed pregnancy. When the S / D value is more than or equal to 2.5, prenatal care should be strengthened to terminate the pregnancy timely.
