摘要

目的:我们的研究旨在检查超声和产科参数,探讨它们的相互关系,并评估它们在决定引产成功的预测能力。方法:无并发症的单胎妊娠,胎龄40周零3天,胎儿头位,胎膜完整,Bishop评分不佳(BS)的妇女。结果:在70名纳入的妇女中,只有29名(41.4%)妇女对引产有反应。CL、BS和胎儿MCA PI的平均值在对IOL有反应的妇女和对IOL无反应的妇女中有显著差异。MCA、PI、BS、CL 4个变量对诱导成功的预测模型敏感性为100%,特异性为90.2% (AUC 0.982, 95% CI: 0.96 ~ 1.00, p < 0.001),上截止值为0.47。EFW对预后参数没有影响。结论:MCA PI、CL和BS组成的模型对评估足月妊娠妇女人工晶状体的疗效有很好的预测价值。当必须评估单个参数时,CL是预测诱导成功的最佳母体因素。

Objective: Our study aimed to examine ultrasound and obstetric parameters, explore their interrelationships, and assess their predictive ability in determining the success of labor induction. Methodology: Women with uncomplicated singleton pregnancy at a gestational age of 40 weeks and 3 days with fetal cephalic presentation, having intact fetal membranes and unfavorable Bishop score (BS < 6) were recruited for the study. Ultrasound examination was performed to measure cervical length (CL), estimated fetal weight (EFW), and Doppler velocimetry of fetal cerebral vessels in each patient before induction. We proposed to combine the variables of CL, EFW, BS, and middle cerebral artery pulsatility index (MCA PI) to devise a model for the prediction of successful induction of labor (IOL). IOL was performed with intracervical prostaglandin E2 gel (3 g gel/0.5 mg dinoprostone) applied 6 h apart if needed, not more than 2 doses, followed by oxytocin infusion for up to 6 h. Successful induction was defined as the initiation of active labor at any stage of the induction process. Results: Among the 70 enrolled women, only 29 (41.4%) women responded to induction. CL, BS, and mean value of fetal MCA PI had significant differences in women who responded from those who did not respond to the IOL. The prediction model for the success of induction with the four variables of MCA PI, BS, and CL has a sensitivity of 100% and specificity of 90.2% (AUC 0.982, 95% CI: 0.96-1.00, p < 0.001) with the upper cutoff of 0.47. EFW showed to have no effect on the outcome parameter. Conclusion: A model comprising MCA PI, CL, and BS has an excellent prediction value to assess the response to IOL in women at term pregnancy. When a single parameter has to be evaluated, CL is the best maternal factor to predict the success of induction.
