Abstract

ObjectiveTo characterize the viscoelastic properties of cervical mucus plugs (CMPs) shed during labor at term. DesignExperimental research. SettingDepartment of Obstetrics and Gynecology, Aarhus University Hospital, Denmark. Population/SampleSpontaneously shed CMPs from 18 healthy women in active labor. MethodsViscoelastic properties of CMPs were investigated with a dynamic oscillatory rheometer using frequency and stress sweep experiments within the linear viscoelastic region. Main outcome measuresThe rheological variables obtained were as follows: elastic modulus (G), viscous modulus (G) and tan delta (G/G). Random-effects regression was used for statistical analysis. ResultsAll CMPs showed solid-like viscoelastic behavior. This was substantiated by the elastic modulus which was three to four times greater than the viscous modulus and by tan delta, which was
