for optimal patient care|Latest 2025 Revised Update
with complete solution.
What is the definition of PROM? - answer-Spontaneous rupture of membranes
prior to the onset of labor
What is the definition of PPROM? - answer-Membrane rupture prior to the
onset of labor and prior to 37 0/7 weeks gestation
What is the definition of prolonged PROM? - answer-ruptured membrane
duration > 24 hours
What is the definition of latency? - answer-interval between rupture of
membranes and onset of labor
Why does ROM normally occur? - answer-- Contractions can lead to ROM due
to increased intra-amniotic pressure
- Membrane rupture at the internal cervical os more likely with advancing
dilatation due to lack of anchoring to supportive decidua and decreasing
membrane stretch
What are the possible causes of PROM? - answer-Poor nutrition
Previous PROM
Multiple gestation
, Polyhydramnios
Cigarette smoking
Previous cervical surgery
Unknown cause
What is the prognosis for expectant management with PROM? - answer-50% in
labor within 12 hrs
70% within 24 hrs
85% within 48 hrs
95% within 72 hrs
What are the maternal risks with PROM? - answer-Intrauterine infection (9%;
↑ 24% with ROM > 24 hrs)
Endometritis (2-13%)
Abruption (4-12%)
Length of labor/hospitalization
? Induction and increase in Cesarean rate?
What are the fetal risks with PROM? - answer-Umbilical cord
compression/prolapse
Infection
When is expectant management of PROM reasonable? - answer-Term,
uncomplicated pregnancy
