摘要
目的:探讨多普勒超声在围产期孕妇的应用价值。方法:将340例正常单胎孕妇分娩前1周及产前检查的多普勒超声检查结果与妊娠结局进行比较。结果:早产9例,过期产2例,其余为足月产。正常孕妇的S/D(收缩期最大血流速度/舒张末期血流速度)、R I(阻力指数)、PI(搏动指数)值均随孕周的增加而降低。足月分娩,S/D≤2.5组新生儿出生体重明显比>2.5组重(P<0.01)。脐带绕颈与无绕颈的脐动脉血流参数无统计学差异。足月妊娠的新生儿,不同出生体重的脐动脉血流参数亦无统计学差异。结论:多普勒超声是简单、易行、有效的检查方法,足月妊娠S/D>2.5时应引起重视,加强监护。脐动脉血流参数不能预测脐带有无绕颈,亦不能预测新生儿出生体重。
Objective: To study the value of Doppler examination in perinatal pregnancy. Methods: The Doppler examinations of 340 normal pregnancies were done within one week before delivery and in the antenatal care. We analyze the relationship between the result of Doppler and the pregnancy outcome. Results: There are 9 preterm births and 2 prolonged births. In normal pregnancy, S/D ( systolic diastolic ratio) , RI (resistance index) and PI (pulse index) decreased with the gestational age advancing. By term delivery, the neonatal weight were significantly higher in the group of S/D≤2. 5 than in the group of S/D 〉 2. 5. There is no significant difference of Doppler umbilical artery flow veloeimetry between in nuehal cord group and in no nuehal cord group . In term delivery, the result of Doppler examination is also no significant difference by the neonatal weight. Conclusion: The Doppler examination is simple, easy and effective. In term pregnancy, when S/D 〉2. 5, more attention should be paid to monitor the fetuses. The Doppler umbilical artery flow velocimetry can not estimate if the cord will be nuchal, and can not calculate the neonatal weight.
