摘　　要：目的探讨经阴道超声测量宫颈长度与宫颈内口宽度对早产预测的价值。方法选择在辽阳市第三人民医院进行产前检查的无任何严重合并症或并发症的单胎头位初产妇198例,在孕25～35周时利用阴道超声检测宫颈长度及宫颈内口的宽度,并观察回访其妊娠结局。结果早产15例(占7.5%),足月产183例(占92.42%),当宫颈内口长度不断的缩短及宫颈内口宽度的逐步增加时,早产的发生率也在随之增加。结论用经阴超声检测孕期宫颈长度与宫颈内口的宽度,能有效的对先兆早产的孕妇进行预测,是一种安全、有效、快速,且可重复使用的检测方法。Objective The thesis discussed the predictive value of cervical length and width in preterm delivery by using transvaginal ultrasonic measurement. Methods 198 cases of primipara with single head position and no serious comorbidity or complication were undergone prenatal diagnosis in our hospital;At the time of 25-35 gestational weeks,transvaginal ultrasonic measurement was carried out on the cervical length and width, and the pregnancy outcome was observed and returned visit. Results Preterm delivery was 15 cases （accounting for 7.5%）, term delivery was 183 cases（accounting for 92.42%）.When the cervical length gradually decreased and the cervical width gradually increased,the rate of preterm delivery increased with the changes of the cervical length and width. Conclusion The transvaginal ultrasonic measurement of cervical length and width in pregnancy will effectively predict the threatened premature labors,so as to improve the diagnostic accuracy of preterm delivery.Therefore,it will be a safe,effective,rapid and reusable test method.
