【摘要】 目的研究先兆早产孕妇宫颈长度对早产的预测价值,为鉴别真假早产,减少滥用药物提供依据。方法选择126例诊断先兆早产胎膜完整的孕妇进行宫颈长度的超声测量,追踪其妊娠结局;同时对100例正常单胎孕妇,分别于24周、28周、32周测量其宫颈管长度,观察正常孕妇不同孕周的宫颈变化。结果①正常单胎孕妇宫颈随着孕周的进展宫颈长度缩短,但无统计学差异;经产妇与初产妇宫颈长度无显著性差异。②126例先兆早产孕妇中发生早产的57例为早产组,未发生早产的69例为非早产组,早产组宫颈长度均明显短于非早产组,两者有显著性差异(P<0.01)。③以宫颈长度<30mm为界值,预测126例先兆早产孕妇发生早产的敏感性为98.2%,特异性为56.5%,阳性预测值为65.1%,阴性预测值为97.5%。结论经阴道超声检测宫颈长度,当其<30mm时早产发生率较高。

【Abstract】 Objective To determine the predictive value of cervical length(CL) in pregnant women with preterm labor and then to raise the possible of intervention study. Methods Transvaginal sonography were performed in 100 normal single pregnant women in 24,28 and 32 weeks of gestation and 126 women with preterm labor and intact membranes.Pregnant outcomes were recorded. Results ①There is no significant change in cervical length between the normal primipara or multipara.②Fifty-seven preterm deliveries occurred among the 126 pregnant women with threatened preterm labor.The cervical length by sonography of preterm deliveries was significantly shorter than the women of pregnancy at term (P<0.01).③ A cervical length of 30mm as the limit to predict the preterm delivery among women with the threatened preterm labor has 98.2% of sensitivity,56.5% of specificity,65.1% of positive predictive value and 97.5% of negative predictive value. Conclusion Cervical length by transvaginal sonography can be used to predict preterm delivery among the women with threatened preterm labor.When the cervical length is less than 30mm ,it indicates a high risk of preterm delivery,and intensive management is required.
