NCT03976063

Brief Summary

The purpose of this study is to assess whether short-term (48 hr) tocolysis reduces perinatal morti-morbidity in cases of PPROM at 22 to 33 completed weeks' gestation.

Outcome Measures

Primary Outcomes (1)

  • Perinatal morti-morbidity

    Composite outcome including fetal death, neonatal death and/or neonatal severe morbidity (mechanical ventilation ≥ 48 hrs, severe bronchopulmonary dysplasia, severe intraventricular hemorrhage, cystic periventricular leucomalacia, neonatal early-onset sepsis, necrotizing enterocolitis, retinopathy of prematurity).

    Up to discharge from hospital, with a maximum of 24 weeks after birth.

Secondary Outcomes (25)

  • Prolongation of gestation

    Up to 20 weeks after PPROM (i.e. up to the maximum duration of a normal pregnancy)

  • Prolongation of gestation

    Up to 20 weeks after PPROM (i.e. up to the maximum duration of a normal pregnancy)

  • Prolongation of gestation

    Up to 20 weeks after PPROM (i.e. up to the maximum duration of a normal pregnancy)

  • Prolongation of gestation

    Up to 20 weeks after PPROM (i.e. up to the maximum duration of a normal pregnancy)

  • Prolongation of gestation

    Up to 20 weeks after PPROM (i.e. up to the maximum duration of a normal pregnancy)

  • +20 more secondary outcomes
