Plain English Summary
Background and study aims
Preterm premature rupture of membranes (PPROM) is a condition where a pregnant woman’s waters break very early in the pregnancy (i.e., before 37 weeks). The amniotic fluid, which surrounds and protects the fetus in the womb, leaks out through the vagina. If PPROM occurs, there is an increased risk of premature delivery and its associated complications, including death of the premature infant. The aim of this study is to find out whether intervention for PPROM can improve outcomes.
Who can participate?
Pregnant women with preterm premature rupture of membranes
What does the study involve?
Participants are randomly allocated to either undergo amnioinfusion (putting fluid back into the womb) or expectant management (watch and wait). The treatment takes place in hospital as an outpatient, although sometimes admission to hospital may be necessary. In the amnioinfusion group, amniotic fluid is replaced weekly until 34 weeks if needed. In the expectant management group, the pregnancy is monitored by weekly scans but no fluid is replaced. The short-term outcomes to be assessed are the number of infant deaths before hospital discharge and infant breathing difficulties, defined as needing oxygen at 28 days after delivery. We test the surviving infants’ lung function and development up to two years of age.

Amnio infusion in preterm premature rupture of membranes (AMIPROM study)
Acronym
AMIPROM
Study hypothesis
The aim of this project is to study whether intervention for premature rupture of membranes (PROM) improves the outcome for babies. The study will compare the neonatal, maternal and pregnancy outcomes in pregnancies with very early PROM managed expectantly or managed with serial amnioinfusions.
