Preterm premature rupture of membranes (PPROM) describes PROM < 37 weeks gestation.
114
Premature rupture of membranes (PROM), diagnosis
Need to confirm that this is truly amniotic fluid.
Speculum - fluid pooling in posterior fornix.
Nitrazine test - blue (due to elevated pH) determine if this is amniotic fluid - PH > 7.1 means it is positive.
Microscope examination: ferning - take a specimen of the fluid put it on a slide and let it air dry will see "fern pattern" crystallization of the amniotic fluid (crystallization of estrogen and amniotic fluid).
115
Premature rupture of membranes (PROM), treatment
Depends on gestational age:
> 34 weeks – induce labor;
32-34 weeks collect fluid and check for lung maturity – then induce;
< 32 weeks stop contractions and start 2 doses of steroid injection then deliver the baby – give antibiotics.
116
RH incompatibility
Rh negative mother, Rh positive fetus.
1st pregnancy is always unaffected.
Give Rhogam at 28 weeks, within 72 hours of delivery and during any uterine bleeding throughout pregnancy.
Given if Rh negative mother and father Rh positive or unknown. Risk of hydrops fetalis
