彩色多普勒超声监测胎儿大脑中动脉血流动力学指标对胆汁酸淤积孕妇胎儿窘迫的评估价值

Evaluation value of color Doppler ultrasound monitoring of hemodynamic parameters in fetal middle cerebral artery on fetal distress in pregnant women with cholestasis

目的:评估彩色多普勒超声监测胎儿大脑中动脉血流动力学指标对预测胆汁酸淤积孕妇胎儿窘迫的价值。方法:选取我院收治的45例胆汁酸淤积孕妇为观察组,同时选取同期于我院产科检查的45例正常晚期妊娠孕妇为对照组,两组均行彩色多普勒超声检测,计算S/D、RI、PI值。记录比较两组胎儿窘迫的发生率、大脑中S/D、PI及RI指标、新生儿出生1min后的Apgar评分。结果:观察组的胎儿窘迫发生率显著高于对照组(P<0.001),观察组的S/D、PI、RI值以及Apgar评分均显著低于对照组(P<0.05或P<0.001)。讨论:彩色多普勒超声监测胎儿大脑中动脉血流动力学指标可准确推断、预测胆汁酸淤积孕妇胎儿窘迫,并可在一定程度上评估Apgar评分较低的新生儿,具有一定的临床参考价值。

Objective: To assess the value of color Doppler ultrasound monitoring of fetal middle cerebral artery hemodynamic parameters in predicting fetal distress in pregnant women with cholestasis. Methods: 54 cases of pregnant women with cholestasis were selected as observation group. And other 45 normal pregnant women at the same time for obstetric examination were selected as control group. The two groups were given color Doppler ultrasound. The values of S/D, RI and PI were calculated, and the incidence rate of fetal distress, the S/D, PI and RI indexes in the brain, and the Apgar score after 1min of birth were recorded and compared between the two groups. Results: The incidence rate of fetal distress in the observation group was significantly higher than that in the control group ( P <0.05). The values of S/D, PI and RI and the Apgar score in observation group were significantly lower than those in control group ( P <0.05). Conclusion: Color Doppler ultrasound monitoring of hemodynamic parameters in fetal middle cerebral artery can accurately infer and predict fetal distress of pregnant women with cholestasis, and can be used to evaluate neonatal Apgar score to a certain extent, and it has a certain clinical reference value.
