Summary

Prevention of preterm birth (PTB) is a key factor for a positive short-term and long-term outcome of the newborn children as mortality and morbidity are inversely related to gestational age at delivery. Consequently every week of prolonged pregnancy will have a tremendous effect concerning the outcome of the new-borns, subsequently for their parents and society as well.

The proposed RCT aims to evaluate the impact of a preventive pessary treatment on the prevention of preterm birth in women with a singleton pregnancy who are at high risk of spontaneous preterm birth (sPTB) due to a history of at least one previous preterm delivery and/or a history of previous cervical surgery. In accordance with the results by "van´t Hooft et al. 2016" an approximately 20% higher percentage of children's long-term survival without neurodevelopmental disability is expected for the pessary group in comparison with usual management (=control group) on basis of a reduction of prematurity \< 34 week of gestation (WoG).

The primary outcome measure for the effect of the pessary treatment in comparison to expectant management will be the children's long-term survival (3yrs) without neurodevelopmental disability. Secondary endpoints assess the impact of a preventive pessary placement on the prevention of preterm birth and its resulting risk on mortality and morbidity for the neonates.

Conditions

Interventions

DEVICE

cervical pessary

Intervention: Device: Cervical pessary: After Having excluded a vaginal infection insertion of the cervical pessary (silicone ring) directly after enrollment. After insertion verification of correct fit of the cervical pessary by transvaginal ultrasound. Removal of the pessary at 37+0 weeks of gestation, or before if any unexpected event occurs. Except for the insertion of the pessary the obstetrical management during the remainder of the pregnancy will be usual management.

OTHER

Control-Group

Intervention: Other: expectant management: expectant management is usual care; interventions only in terms of a tertiary prevention of PTB according to guidelines for premature rupture of membranes, premature labour or other pregnancy complications
