Obcast on PPROM

Educate yourself a little more about ‘Premature rupture of membrane during pregnancy’ as described by Dr. Smita Gutgutia, Sr. Consultant Obs & Gynae, Laparoscopic Surgeon in this chapter.

Have a refreshing weekend, be informed and stay healthy!

This is a brief video on premature rupture of membranes, or the leakage of amniotic fluid before labor.

Leakage of amniotic fluid before labor
Overview
Risk factors and causes
Diagnosis
Management
Chorio-
amnionitis

PROM = premature rupture of membranes
Amniotic sac rupture / fluid spillage more than one hour before onset of labor
Labor = regular contractions + cervical change
PPROM = preterm premature rupture of membranes
Amniotic sac rupture before 37 weeks
Prolonged rupture of membranes
Amniotic sac rupture for longer than 18 hours before delivery

“Gush of fluid” vs steady leakage of fluid
Note color and consistency of fluid
Thick vs watery
Clear, cloudy, meconium, blood-tinged

Chorio-
amnionitis

Vaginal or cervical infections: UTIs, STIs, bacterial vaginosis
Smoking or drug use during pregnancy
PROM or preterm deliveries in previous pregnancies
Nutritional deficiencies; underweight mothers
Polyhydramnios (too much amniotic fluid)
Multiple gestation
Cervical insufficiency (short or prematurely dilated cervix)
Invasive procedures (amniocentesis, cerclage, etc)

Pathophysiology:
Weak fetal membranes
Infections (sometimes subclinical)
Genetics

Three classic tests
Pooling: Collection of fluid in the vagina (posterior fornix)
Nitrazine: Neutral fluid turns nitrazine paper blue; vaginal fluid usually acidic. Amniotic fluid is mildly acidic → blue nitrazine paper
False positives: blood, semen, infections, antiseptics, lubricant
Ferning: Dry amniotic fluid on glass slide has crystallization pattern called arborization that resembles fern plant on light microscopy

Ultrasound can detect low levels of fluid (low residual fluid levels)
Other new tests detect chemicals or proteins in amniotic fluid

Management
Chorio-
amnionitis
Previable
24 weeks
Watchful waiting; no tocolytics, steroids, MgSO4, or abx
Induction of labor to end pregnancy
Preterm
24-33 weeks
Tocolytics to prevent labor; steroids twice 24 hrs apart for lung maturity; MgSO4 as tocolytic while lungs mature; abx for GBS prevention
Amnioinfusion to replace lost fluid is controversial
Late preterm
34-36 weeks
Induce labor; abx for GBS prevention
Term
37 weeks
Induce labor; abx for GBS prevention

Definition: infection of chorion, amnion, and/or amniotic fluid surrounding fetus
Diagnosis:
Signs and symptoms: fever, rupture of membranes, leakage of fluid, uterine tenderness, elevated maternal heart rate ( 100 bpm), elevated fetal heart rate (160 bpm)
Fever: exclude maternal URI and UTI
Labs: increased white count ( 15,000 cells/mm³)
Treat with ampicillin, gentamicin, and clindamycin
Induce delivery
Covers gram negatives and anaerobes
Afebrile for 24 hours
