子宫动脉超声多普勒血流监测在高危妊娠晚期的应用价值

Application value of uterine artery ultrasound Doppler blood flow monitoring on high risk pregnancy

目的:探讨子宫动脉超声多普勒血流监测在高危妊娠晚期的应用价值。方法:选取2015年2月至2016年2月本院接收的50例高危妊娠晚期孕妇为观察组,50例正常妊娠女性为对照组。观察观察组与对照组的收缩期峰值流速/舒张末期流速(peak systolic velocity/end diastolic velocity,S/D)、搏动指数(pulsatility index,PI)和阻力指数(resistance index,RI)及有无舒张期早期切迹,并比较不同超声S/D值及有无舒张期早期切迹的高危妊娠晚期产妇妊娠结局的差异。结果:观察组S/D值显著高于对照组,且发生舒张早期切迹的比例显著高于对照组(P<0.05)。两组RI及PI比较,差异均无统计学意义(P>0.05)。与S/D值正常者比较,S/D值异常者新生儿体重及Apgar评分更低,发生早产、新生儿窘迫及转ICU的比例更高(P<0.05)。与无舒张早期切迹者比较,存在舒张早期切迹者新生儿体重及Apgar评分更低,发生早产、新生儿窘迫及转ICU的比例更高,差异具有统计学意义(P<0.05)。结论:超声测量子宫动脉参数有助于评估高危妊娠结局,其中S/D及舒张早期切迹有重要的临床意义。

Objective：To explore the application value of uterine artery ultrasound Doppler blood flow monitoring on high risk pregnancy. Methods ：50 cases of high risk pregnant women in our hospital were selected as observation group from February 2015 to February 2016,50 cases of normal pregnancy women as control group. Peak systolic velocity/end diastolic velocity （S/D） , pulsatility in- dex（PI） , resistance index（ RI） , early diastolic notch in the patients of two groups were observed, and the difference of outcome of preg- nancy in different S/D ratio and with or without early diastolic notch of high risk pregnant women were compared. Results：The value of S/D of women in the observation was significantly higher than that in the control group, occurrence of early diastolic notch in women in the observation was significantly higher than that in the control group （ P 〈 0.05 ）. The value of RI and PI in two groups had no statisti- cal significance （ P 〉 0.05 ）. Compared with the normal value of S/D, the neonatal weight and Apgar score with abnormal value of S/D were much lower,and the incidence of preterm birth, neonatal distress and the ratio of ICU were much higher （P 〈 0.05 ）. Compared with no early diastolic notch comparison,the neonatal weight and Apgar score With early diastolic notch comparison were much lower, and the incidence of preterm birth, neonatal distress and the ratio of ICU were much higher,the differences were statistically significant （P 〈 0.05 ）. Conclusion ： Ultrasound measurement of uterine artery parameters is helpful to evaluate the outcome of high risk pregnan- cy, and value of S/D and early diastolic notch has important clinical significance.
