In brief — the direct answer
Preterm Prelabor Rupture of Membranes (PPROM) is a condition where the amniotic sac—the water-filled bag around the baby—ruptures before 37 weeks of pregnancy. This is often described as the 'water breaking early.' Once the membranes are ruptured, the protective seal around the baby is gone, increasing the risk of infection (chorioamnionitis) and usually leading to premature birth. At the MFM Unit, we focus on a 'watchful waiting' approach, using medication to mature the baby's lungs and prevent infection while monitoring you closely in the hospital.
What is Preterm Prelabor Rupture of Membranes (PPROM)?
PPROM means that the membranes break before labour and before 37 completed weeks. Management depends on gestation, infection, bleeding, labour, the baby’s condition and family preferences. Continuing pregnancy may benefit maturity when clinically appropriate, but is not safe in every case. There is no single target week that applies to all PPROM pregnancies.
Who is at risk?
PPROM can happen unexpectedly, but factors include:
- Previous PPROM: In a prior pregnancy.
- Infection: Silent infections in the vagina or cervix.
- Cervical Weakness: A cervix that has shortened or opened early.
- Multiple Pregnancy: Twins or triplets putting more pressure on the membranes.
- Smoking: A known risk factor for membrane weakness.
How we diagnose it
Confirming PPROM involves a gentle assessment:
- Clinical Check: A sterile speculum exam to look for 'pooling' of fluid in the vagina.
- Biochemical Tests: Using swabs (like Actim Prom or Amnisure) that detect specific proteins found only in amniotic fluid.
- Ultrasound: Checking the level of fluid remaining around the baby (AFI).
What does management involve?
Hospital assessment confirms whether membranes have ruptured and checks for infection and other complications. Depending on gestation and the applicable guideline, care can include a prescribed antibiotic course, corticosteroids when early birth is anticipated, and magnesium sulphate for fetal neuroprotection when eligible. Drug choice, duration and timing are protocol-specific. Delivery is considered for infection, significant bleeding, labour, fetal compromise or other indications; later-gestation timing should be discussed individually.
What are the outcomes?
Outcome depends strongly on gestation at rupture, remaining fluid, infection, latency and the baby’s condition. Monitoring and treatment reduce selected risks but cannot guarantee prevention of infection, early birth or lung complications. Very early PPROM requires specialist counselling about maternal risks, neonatal possibilities and the available care options.
When to see a subspecialist
If you feel a 'gush' or a 'constant trickle' of fluid from your vagina, you must seek medical attention immediately. Do not wait for contractions to start.
Our team, led by Dr. Leanne Bricker, provides expert high-risk obstetric care for PPROM. We offer a safe and supportive hospital environment where you and your baby can be monitored by specialists until the safest time for delivery.
