摘要
目的探讨阴道超声监测妊娠期子宫颈对早产的预测价值。方法纳入研究的孕妇133例,其中33例有先兆早产症状,于妊娠16~36周经超声测量宫颈长度,并随访其妊娠结局。结果(1)阴道指诊Bishop评分和阴道B超两种方法用于测量宫颈长度,以阴道B超为优。(2)孕28周后宫颈长度与孕周呈负相关。宫颈长度缩短,发生早产的危险性增加。(3)宫颈长度≤30mm、宫颈漏斗形成预测早产的敏感性为100%,特异性为86.9%。结论以阴道B超检测妊娠期宫颈变化是一种客观、有效、可重复的预测早产的方法。
Objective To observe the changes of cervix in the normal pregancy using ultrasound and to predict preterm delivery.Methods Ultrasonography was performed in 100 normal single nuttiparous pregnant women between 16 and 36 weeks of gestation and 33 women with threatened preterm labor were observed the changes of the cervical length and the presence of funneling.Results(1)Compare to use transvaginal Bishops and transvaginal sonography,the latter was the best.(2)After 28 weeks the cervix length was contact with p...
