BACKGROUND
Identification of pregnant women presenting with threatened preterm labor who are destined to deliver prematurely would greatly assist planning their management.
OBJECTIVES
The purpose of the study was to evaluate the ultrasonographic measurement of cervical length as a prognostic factor for predicting preterm birth in cases of threatened preterm labor.
METHODS
The study included 104 women with singleton pregnancies who presented with threatened preterm labor at 24-36 weeks of gestation. Cervical length at presentation was evaluated by transvaginal ultrasonography. Other potential prognostic factors, such as previous history of preterm labor, smoking, parity and administration of tocolytics were assessed. All women were observed for preterm delivery within 7 days of presentation.
RESULTS
The only significant predictor of preterm delivery was cervical length assessed by ultrasound (p<0.000001, odds ratio 93.3, 95% Cl 10.4-837.1).
CONCLUSIONS
Cervical length assessed by transvaginal ultrasonography in women presenting with threatened preterm labor is a powerful predictive tool for progression to preterm delivery.
背景
识别有早产先兆的孕妇中注定会早产的情况，将极大地有助于规划她们的治疗方案。
目的
本研究的目的是评估宫颈长度的超声测量作为预测早产先兆病例早产的一个预后因素。
方法
本研究纳入了104名单胎妊娠孕妇，她们在妊娠24至36周时出现早产先兆。通过经阴道超声评估就诊时的宫颈长度。评估其他潜在的预后因素，如早产史、吸烟、产次和使用宫缩抑制剂情况。所有妇女在就诊后7天内观察是否早产。
结果
早产的唯一显著预测因素是超声评估的宫颈长度（p<0.000001，优势比93.3，95%可信区间10.4 - 837.1）。
结论
经阴道超声评估的宫颈长度是有早产先兆的妇女进展为早产的有力预测工具。
