摘　　要：目的:探究孕晚期宫颈弹性成像参数对足月产妇第一产程延长的预测价值。方法:选择2020年8月-2021年8月本院妇产科收治的足月待产产妇82例临床资料,产妇均于孕晚期接受经阴道超声检查,测量宫颈长度(CL)和宫颈弹性成像参数[弹性对比指数(ECI)、硬度比(HR)、宫颈内口应变平均值(IOS)、宫颈外口应变平均值(EOS)],分析检查参数与产妇第一产程延长关系。结果:82例产妇中24例第一产程延长(延长组),58例第一产程正常(正常组),延长组CL、HR水平高于正常组,ECI水平低于正常组(均P<0.05);两组IOS、EOS水平比较无差异(P>0.05)。相关性分析显示,CL、ECI与第一产程时间负相关(均P<0.05),HR、IOS、EOS与第一产程时间无相关性(P>0.05);CL、ECI预测足月待产产妇第一产程延长的受术者工作特征曲线下面积分别为0.819(95%CI 0.718~0.895)和0.854(95%CI 0.759~0.922),敏感度分别为83.3%和75.0%,特异度分别为58.3%和84.5%。结论:足月产妇孕晚期行经阴道超声测量CL和弹性成像参数ECI可评估宫颈成熟度,并可有效预测第一产程延长,指导引产。Objective:To explore the predictive value of cervical elastography parameters of full-term pregnant women during the third trimester of pregnancy on their prolongation of the first stage of labor.Methods:The clinical data of 82full-term pregnant and lying-in women between August 2020and August 2021were selected in this study.All these women had received transvaginal ultrasound examination during the third trimester of pregnancy to measure their cervical length(CL)and the cervical elastography parameters,such as elasticity contrast index(ECI),hardness ratio(HR),mean value of internal cervical orifice strain(IOS),and mean value of external cervical orifice strain(EOS).The correlation between the examination parameters of the women and their prolongation of the first stage of labor was analyzed.Results:Among 82women,there were 24women with the prolonged first stage of labor(in group A)and 58cases with normal first stage of labor(in group B).The CL and HR values of the women in group A were significantly higher than those of the women in group B,and the ECI value of the women in group A was significantly lower(P<0.05).There were no significant differences in the IOS and EOS values of the women between the two groups(P>0.05).Correlation analysis showed that the values of CL and ECI of the women were negatively correlated with their duration of the first stage of labor(P<0.05),but the values of HR,IOS,and EOS of the women had no correlation with their duration of the first stage of labor(P>0.05).The area under of receiver operating characteristic(ROC)curve of the CL and ECI values of the women for predicting their first stage of labor prolong were 0.819(95%CI 0.718?0.895)and 0.854(95%CI 0.759-0.922),the sensitivity of which were 83.3%and 75.0%,and the specificity of which were 58.3%and 84.5%.Conclusion:The values of transvaginal ultrasound measurement of CL and elastography parameter of ECI of the full-term women during the third trimester of pregnancy can assess their cervical maturity,and can predict their first stag
