Abstract

Objective: We studied whether Doppler flow measurements before initiation of induction of labor (IOL) can predict non-reassuring fetal heart rate (NRFHR) monitoring in women at 38-41 weeks of gestation.

Materials and methods: We performed a prospective observational study in a single tertiary medical center between November 2017 and December 2019. Women undergoing induction of labor were included. Each woman underwent sonographic studies before initiating IOL. The pregnancy outcome in those who developed NRFHR and those with reassuring FHR during labor were compared and correlated with baseline Doppler flow indices and method of induction.

Results: Overall, 219 women were included, of whom 133 underwent IOL with prostaglandin E2 and 86 with a Foley catheter balloon. On multivariate logistic regression analysis, a lower MCA-PI percentile was associated with NRFHR in women that were induced with prostaglandin E2.

Conclusion: A lower middle cerebral artery pulsatility index value might represent a lower placental reserve and, therefore, a higher risk of NRFHR monitoring during labor. This finding might assist in selecting the appropriate method of IOL.

多普勒研究在预测引产后不可靠胎儿心率监测中的作用。
目的:探讨人工引产(IOL)开始前多普勒血流测量是否能预测妊娠38 ~ 41周女性非安心胎心率(NRFHR)监测。材料和方法:我们于2017年11月至2019年12月在一家三级医疗中心进行了一项前瞻性观察研究。接受引产的妇女也包括在内。每位妇女在实施人工晶状体前都进行了超声检查。在分娩过程中,对发生NRFHR的孕妇和有安心FHR的孕妇的妊娠结局进行比较,并与基线多普勒血流指数和引产方法相关。结果:总共包括219名妇女,其中133名接受了前列腺素E2人工晶状体植入,86名接受了Foley导尿管球囊植入。在多变量logistic回归分析中,低MCA-PI百分位数与前列腺素E2诱导的女性NRFHR相关。结论:较低的大脑中动脉脉搏指数值可能代表较低的胎盘储备,因此在分娩时监测NRFHR的风险较高。这一发现可能有助于选择合适的人工晶状体植入方法。
