Management of Preterm Prelabor Rupture of Membranes
Initial Assessment and Classification
- The American College of Obstetricians and Gynecologists defines preterm prelabor rupture of membranes (PPROM) as membrane rupture before labor that occurs before 37 weeks of gestation 2
Management Algorithm Based on Gestational Age
- For patients with previable and periviable PPROM, the American College of Obstetricians and Gynecologists recommends individualized counseling about maternal and fetal risks of both abortion care and expectant management 1
- Expectant management is associated with higher maternal morbidity (60.2%) compared to abortion care (33.0%) in patients with PPROM 3
- Common complications of expectant management include intraamniotic infection (38.0% with expectant management vs 13.0% with abortion care) and postpartum hemorrhage (23.1% vs 11.0%) 3
- Only 16% of patients with expectant management avoid maternal morbidity and have an infant who survives to discharge 4
- For patients choosing abortion care, procedural abortion (D&E) may have fewer complications than medication abortion (induction of labor) 5
- Complications are more frequent after induction of labor than after D&E (hemorrhage >500cc: 28.3% vs 9.1%; infection: 23.9% vs 1.3%) 5
- For patients choosing expectant management, antibiotics can be considered after PPROM at 20 0/7 to 23 6/7 weeks 1
- Monitor closely for signs of intraamniotic infection, which may present without maternal fever 5
- Serial amnioinfusions and amniopatch are considered investigational and should only be used in clinical trial settings 1, 6
Monitoring and Management
- Antibiotics are recommended for patients choosing expectant management at 24 0/7 to 33 6/7 weeks 1
- Antenatal corticosteroids and magnesium sulfate are not recommended until the time when neonatal resuscitation would be considered appropriate 1
- Cerclage management after PPROM requires shared decision-making regarding removal or retention 1, 2
- Regular assessment for signs of intraamniotic infection (maternal temperature ≥38°C, maternal tachycardia, purulent cervical discharge, fetal tachycardia, uterine tenderness) is necessary during expectant management 5
- Clinical diagnosis of infection should not be delayed due to absence of maternal fever 5
- Delaying intervention when signs of infection are present can lead to serious maternal complications including sepsis and death 1
- Clinical symptoms of infection may be less overt at earlier gestational ages 5
- In pregnancies following previable or periviable PPROM, follow guidelines for management of pregnant persons with a previous spontaneous preterm birth 1
