PREMATURE RUPTURE OF
MEMBRANES (PROM)
KABERA René, MD
Resident PGY II- Family and Community Medicine
Obs-Gyn. Dept Ruhengeri Hospital
Feb 2010.
ESSENTIALS OF DIAGNOSIS
• History of a gush of fluid from the vagina or
watery vaginal discharge.
• Demonstration of amniotic fluid leakage from
the cervix.
• ≥1h before the onset of labor.
KABERA René ,MD PGY II FAMCO NUR
General Considerations
• Rupture of the membranes may happen at
any time during pregnancy.
• It becomes a problem if the fetus is preterm
(preterm) .
• >24 Hrs, prolonged premature rupture of
membranes -time between rupture of the membranes and the onset of labor is.

General considerations c’t
• Causes
�Infections .
�Cervix incompetency.
�Hydramnios …
• 10.7 % in all pregnancy.
• 94% mature fetus (>2500 grs) ,5% premature
fetus (1000-2500 grs),immature fetus
0.5%(<1000 grs).

Pathophysiology
• PROM is an important cause of preterm labor, prolapse of the cord, placental abruption, and intrauterine infection.
• In extremely prolonged PROM, the fetus may have an appearance similar to that of Potter's syndrome (eg, extraordinary flexion, wrinkling of the skin).
• If PROM occurs at less than 26 weeks' EGA, it can cause pulmonary hypoplasia and limb positioning defects in the newborn.

Clinical findings
• Symptoms
• The patient usually reports a sudden gush of
fluid or continued leakage.
• Reduced size of the uterus, and increased
prominence of the fetus to palpation.
• Sterile Speculum Examination
• Pooling , Nitrazine test, Ferning.

Lab test
• CBC , CRP, U/S, Amniocentesis for lung
maturation
• Amniotitis : most common germ is
streptococci B-fever ,leukocytosis (>16000
WBC),uterine tenderness, tachycardia ( >100
btm-mother,>160 btm-fetus ),foul smelling amniotic liquid .

Management
• A.Amniotitis :
delivery regardless of gestational age. Broad-
spectrum antibiotics should be started. if no labor
, labor should be induced to expedite delivery.
• B. Term Pregnancy Without Amnionitis:
• Nonintervention is an acceptable initial course of
treatment, but if the patient does not go into
labor within 6-12 hours after PROM, labor should
be induced to minimize the risk of infection.

Management c’t
• C. Preterm Pregnancy Without Amnionitis
Pregnancies beyond 33-34 weeks' EGA can be managed as a term pregnancy because there is no evidence that antibiotics, corticosteroids, or tocolytics improve outcome in these patients.
• Pregnancies prior to 24 weeks' EGA with PROM have extremely low rates of fetal salvage with considerable maternal risk.
Furthermore, at this early gestational age, steroids, tocolytics, and antibiotics have no proven benefit.
KABERA René ,MD PGY II FAMCO NUR
Management c’t
• For pregnancies with PROM between 24 and
32 weeks' EGA.
• Antibiotics.
• Corticosteroids.
• Tocolytics :In the preterm PROM patient should be limited to 48 hours duration.
