Preterm Labor Prediction by Cervical Contour in Ultrasound
Recruitment status was: Recruiting
Cervical length is a already known predictor for preterm labor. In this study the investigators want to examining the hypothesis that cervical curvature is also a predictor for preterm labor and that moderate transducer pressure influence cervical length.
study population: 200 consecutive pregnant women between 14-34w, visiting in the ultrasound unit ether for routine screening or because of preterm labor.
During their examination cervical length and curvature measurements will be taken. Another measurement will be taken after applying moderate cervical pressure.
The investigators will compere cervical contour and pressure influence between groups and according to cervical length Demographic data will be taken at the time of recruitment and pregnancy outcome measures in a later telephone interview.
|Study Design:||Observational Model: Case Control|
- cervical curvature [ Time Frame: 12 months ]
|Study Start Date:||August 2013|
|Estimated Primary Completion Date:||August 2014 (Final data collection date for primary outcome measure)|
pregnant women with signs of preterm labor: uterine contractions or cervical shortening
pregnant women with no signs or symptoms of preterm labor
