摘　　要：目的:探讨E-Cervix弹性成像参数预测足月妊娠引产宫颈反应的敏感性及与分娩活动期宫颈管扩张时间关系。方法:回顾性分析2021年5月-2022年1月在本院住院单胎足月妊娠拟引产的孕妇124例,按照引产期间宫口扩张时间分为敏感组(n=66)及不敏感组(n=58),采用E-Cervix技术检测孕妇引产前12h各弹性成像参数,评估各组宫颈成熟度评分(Bioshop);绘制受试者工作特征曲线(ROC)分析E-Cervix弹性成像各参数及Bioshop评分对宫颈反应敏感的预测价值;比较两组宫颈扩张时间;采用Pearson相关系数分析宫颈扩张时间与E-Cervix参数的相关性。结果:敏感组Bishop评分(3.26±0.56分)低于不敏感组(3.89±0.87分),E-Cervix弹性成像各参数均高于不敏感组(均P<0.05)。ROC曲线分析,E-Cervix弹性成像技术评估宫颈反应敏感的曲线下面积(0.869)高于Bishop评分(0.746),其敏感度87.4%,特异度82.7%;敏感组宫颈扩张时间(190.0±58.6min)短于不敏感组(226.8±57.6min)(均P<0.05)。Pearson相关性分析,宫颈扩张时间与E-Cervix弹性成像各参数均呈正相关(P<0.05)。结论:利用E-Cervix弹性成像能够有效预测宫颈反应敏感,且各参数与宫颈扩张时间成正相关。Objective: To investigate the predictive value of the parameters of elastography of cervix(E-cervix) of pregnant women for their cervical sensitivity, and to study the correlation between these parameters of the women and their cervical dilation time during active stage of labor. Methods: 124 full-term pregnant women with singleton who were hospitalized for induce labor from May 2021 to January 2022 were analyzed retrospectively. These women were divided into group A(66 women with sensitive cervix for dilation) and group B(58 women without sensitive cervix for dilation) according to the time of uterine orifice dilation during labor induction. The elastic imaging parameters of the women in the two groups at 12h before labor induction were evaluated by E-cervix technique and the Bioshop score of the women in the two groups was also evaluated. Receiver operating characteristic(ROC) curve was drawn to analyze the predictive values of E-Cervix parameters and Bioshop score for the cervical sensitivity. The cervical dilation time of the women was compared between the two groups. Pearson correlation coefficient was used to analyze the correlation between the cervical dilation time of the women and their E-Cervix parameters. Results: The Bishop score(3.26±0.56 points) of the women in group A was significantly lower than that(3.89±0.87 points) of the women in group B, and the values of E-Cervix elastic imaging parameters of the women in group A were significantly higher than those of the women in group B(all P<0.05). ROC curve analysis showed that the area under the curve(0.869) of E-Cervix parameters for evaluating the cervical sensitivity was significantly higher than that(0.746) of the Bishop score. The sensitivity and the specificity of E-Cervix parameters for evaluating the cervical sensitivity were 87.4% and 82.7%. The cervical dilation time(190.0±58.6min) of the women in group A was significantly shorter than that(226.8±57.6min) of the women in group B(all P<0.05). Pearson correlation analysis showed that the ce
