Management of Preterm Prelabor Rupture of Membranes (PPROM)

Initial Assessment and Management

The American College of Obstetricians and Gynecologists recommends that all patients with PPROM receive individualized counseling about maternal and fetal risks, be offered abortion care regardless of gestational age, and if expectant management is chosen, receive antibiotics at ≥24 weeks gestation with antenatal corticosteroids and magnesium sulfate reserved only when neonatal resuscitation would be pursued 1
Assessment for signs of infection, including maternal fever, uterine tenderness, fetal tachycardia, and purulent or malodorous vaginal discharge, is crucial in patients with PPROM 2, 3
Gestational age determination is critical for all subsequent management decisions in PPROM 1

For previable PPROM (<20 weeks), the American College of Obstetricians and Gynecologists recommends offering abortion care as the primary option due to extremely high maternal risks and minimal chance of fetal survival 1, 3
For periviable PPROM (20 0/7 to 23 6/7 weeks), abortion care remains a strongly recommended option given poor neonatal outcomes and maternal infection risks 1, 3
For PPROM at ≥24 weeks, strongly recommend antibiotics (GRADE 1B) and prepare for potential delivery with appropriate interventions 1, 2

Administer a 7-day course of antibiotics, starting with IV ampicillin plus erythromycin for 48 hours, followed by oral amoxicillin plus erythromycin for 5 additional days 2, 3
Azithromycin may replace erythromycin if unavailable 3
Avoid using amoxicillin-clavulanic acid due to increased risk of neonatal necrotizing enterocolitis 2, 3

Administer betamethasone only when gestational age is ≥24 weeks, delivery is anticipated within 7 days, and the healthcare team and patient agree that neonatal resuscitation and intensive care would be pursued 1, 5
Dosing consists of two 12 mg intramuscular doses of betamethasone 24 hours apart 5

Administer magnesium sulfate when delivery is anticipated before 32 weeks and neonatal resuscitation is planned to decrease cerebral palsy incidence in preterm infants 3

Daily temperature monitoring by the patient and weekly outpatient assessment of maternal vital signs, fetal heart rate, physical examination, and laboratory evaluation for leukocytosis are recommended 4, 2
