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).

Condition or disease Intervention/treatment
Preterm Delivery Device: CERVICAL ASPIRATOR 3.2

Layout table for study information
Study Type : Observational
Estimated Enrollment : 530 participants
Observational Model: Cohort
Time Perspective: Prospective
Official Title: Biomechanics Based Prediction of Preterm Delivery
Actual Study Start Date : April 2014
Estimated Primary Completion Date : July 31, 2019
Estimated Study Completion Date : July 31, 2019

Group/Cohort Intervention/treatment
Pregnancy Device: CERVICAL ASPIRATOR 3.2
No intervention is done except for measuring the stiffness of the cervix in pregnant women




Primary Outcome Measures :
  1. Difference in cervical stiffness in women with/without preterm delivery [ Time Frame: Measurements at 20 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.
