PPROM — Preterm Prelabor Rupture of Membranes

Water breaks before 37 weeks. Management balances risks of prematurity against risks of infection, and depends heavily on gestational age.

What it is

PPROM complicates about 3% of pregnancies but causes a third of preterm births. Standard care usually includes hospital admission, antibiotics (to prolong latency), corticosteroids for lung maturation, and magnesium sulfate for neuroprotection under 32 weeks. Timing of delivery depends on gestational age, infection signs, and fetal status.

Current evidence

ACOG Practice Bulletin 217 and SMFM guidance recommend latency antibiotics (7-day course), antenatal steroids at 24–34 weeks (and up to 36+6), and magnesium sulfate for neuroprotection under 32 weeks.

Where the evidence is clear · where people may choose differently

For most topics, guidelines from ACOG, WHO, and other major bodies broadly agree on the core safety points (when to act in an emergency, informed-consent standards, monitoring baselines). Where reasonable people — and even guidelines — differ tends to be around thresholds (when to start or stop something), preferences (comfort, environment, support), and values (how you weigh small risks against benefits). Use the questions below to explore those pieces with your care team.

Questions to ask your care team

  • ?What is the NICU level here and would we transfer?
  • ?What's the plan for antibiotics, steroids, and magnesium?
  • ?What signs would prompt earlier delivery?
  • ?What can I do about mental health while admitted?

Universal questions (works for any decision)

A short BRAIN-style set you can bring to any conversation about interventions, monitoring, or care decisions.

  • ?Why are you recommending this now — is it urgent, routine, or optional?
  • ?What happens if we wait an hour (or longer) before deciding?
  • ?What signs would tell us this is working — or that we need to change course?
  • ?What are the alternatives, including doing nothing?
  • ?What would you recommend if this were your family?
  • ?What would change your recommendation?
