Biomechanics Based Prediction of Preterm Delivery

Completed

• Conditions: Preterm Delivery

• Registration Number: NCT02037334
• Lead Sponsor: David Scheiner

Brief Summary

Quantitative information on the biomechanical properties of the ecto-cervix in mid-pregnancy will be compared between women with term vs. preterm delivery. We aim to demonstrate that biomechanical data (ASP and CCI) might complement morphological data (CL) to improve prediction of preterm delivery. It is expected that women with preterm delivery will show stronger weakening of cervical tissue. Aspiration (ASP) and cervical CCI (cervical consistency index) measurements are performed at mid-pregnancy: detection at this time point is useful for therapy and biomechanical modifications are already significant so to enable differentiation by biomechanical measurements (ASP and CCI).

Primary Outcome Measures

Name	Time	Method
Difference in cervical stiffness in women with/without preterm delivery	Measurements between 18+0/7 and 22+0/7 weeks of pregnancy and postpartum	The biomechanical measurements and morphological data obtained at mid-pregnancy are compared between women with/without preterm delivery and are expected to significantly differ. The diagnostic power for preterm delivery of aspiration, CCI and the other factors will be determined.
