BACKGROUND
The use of cervical strain elastography for nulliparous women during late-term pregnancy remains unclear. This study assesses the predictive value of late-term cervical strain elastography for successful induction of labor (IOL) in nulliparous women.
METHODS
This single-centered, prospective study included 86 patients undergoing IOL between January 2020 and March 2022. Univariate and multivariate analyses were conducted to identify predictive factors for successful IOL. The predictive values were assessed using the area under receiver operating characteristic (ROC) curves.
RESULTS
IOL was successful in 58 patients. The hardness ratio and cervical length were significantly associated with successful late-term IOL in nulliparous women. The predictive value of the combination of hardness ratio and cervical length was higher than that of cervical length alone.
CONCLUSIONS
The hardness ratio and cervical length assessed by cervical strain elastography during late-term pregnancy are predictors of the success of IOL in nulliparous women. The predictive value of the combination of hardness ratio and cervical length was higher than that of cervical length alone.
背景
在晚期妊娠中，颈应变弹性成像在未产妇中的应用尚不清楚。本研究评估了颈应变弹性成像在预测未产妇引产（IOL）成功中的价值。
方法
本单中心前瞻性研究纳入了 2020 年 1 月至 2022 年 3 月期间接受 IOL 的 86 例患者。采用单因素和多因素分析确定预测 IOL 成功的因素。采用受试者工作特征（ROC）曲线下面积评估预测价值。
结果
58 例患者 IOL 成功。硬度比和宫颈长度与未产妇晚期 IOL 成功显著相关。硬度比和宫颈长度联合预测的价值高于单纯宫颈长度。
结论
在晚期妊娠期间通过颈应变弹性成像评估的硬度比和宫颈长度是预测未产妇 IOL 成功的指标。硬度比和宫颈长度联合预测的价值高于单纯宫颈长度。
