摘要
目的探讨经阴道超声测量宫颈长度在足月初产妇宫颈成熟度诊断中的价值。方法临床纳入足月初产妇117例,均为我院2014年1月至2015年1月收住的分娩产妇分别对其宫颈长度、宫颈管宽度以及宫颈内口契形区宽度等进行测量,同时进行宫颈Bishop评分。结果产妇宫颈长度以及宫颈管宽度与宫颈Bishop评分存在显著相关性(P<0.05),另外其还能预测产妇将在3 d内临产,尤其以宫颈长度的预测效果最好。当产妇宫颈长度<30 mm时,预测其在3 d分娩的敏感性、特异性、阳性预测值以及阴性预测值为0.80、0.87、0.88、0.80。多因素分析结果显示,经阴道超声测量宫颈长度,预测宫颈成熟度以及分娩时间等方面均明显优于其它指标。结论经阴道超声测量宫颈长度能够用于临床上评价足月初产妇分娩前的宫颈成熟度情况,值得推广。
Objective To study the diagnosis significance of cervical maturity through transvaginal ultra- sonography measurement of cervical length for full - term nulliparous women. Method 117 full - term nulli- parous women who come to our hospital from 2014 January to 2015 Januarywere selected. The cervical length, width of cervical canals, width of wedge - shaped parts of intracervical mouth was measured and the cervical Bishop scores were obtained. Result The cervical length, width of cervical canals and cervical Bishop scores were significantly correlated（P〈 0.05）; when the cervical length was less than 30mm, the sensibility, Specificity, positive predictive value and negative predictive value within 3 days of delivery was 0.80, 0.87, 0.88 and 0.80. According to the multiple - factor analysis, the prediction of cervical maturity and delivery time through transvaginal ultrasonography measurement of cervical length was significantly better than other indicators. Conclusion The transvaginal ultrasonography measurement of cervical length is applicable to predict the antepartal cervical maturity for fullterm nulliparous women. It is worthy of clinical promotion.
