ClassificationClassification Type I or low lying: The placenta encroaches the lower
segment of the uterus but does not infringe on the cervical os
Type II or marginal: The placenta touches, but does not cover, the top of the cervix.
Type III or partial: The placenta partially covers the top of the cervix
Type IV or complete: The placenta completely covers the top of the cervix

DiagnosisDiagnosis DO NOT DIAGNOSE via vaginal exam!
(Exception-”double setup”) Ultrasound is the easiest, most reliable
way to diagnose (95-98+% accuracy) False positive- ultrasound with distended bladder Transvaginal or transperineal often superior to
transabdominal methods

MigrationMigration Clinically important bleeding is not likely before
24-26 weeks gestation The clinically important diagnosis of placenta previa
is therefore a late second or early third trimester diagnosis
Migration is a misnomer- the placental attachment does not change, the relative growth of the lower segment does

InterventionIntervention Although mothers used to be treated in the hospital
from the first bleeding episode until birth, it is now considered safe to treat placenta praevia on an outpatient basis if the fetus is at less than 30 weeks of gestation, and neither the mother nor the fetus are in distress.
Bedrest probably indicated Antenatal testing probably indicated

considered Consideration for RHIG in rh negative patients with
bleeding Episodic AFS testing with bleeding events Vigilance regarding fetal growth Follow up ultrasound if indicated

Conservative measuresConservative measures If the bleeding is not life threatening or, if initially
severe but begins to settle, then there is a place for conservative measures
If the fetus is still preterm and the bleeding is under control, a policy of conservative management should be followed, at least until fetal maturity is achieved.

DeliveryDelivery
Delivery should depend upon type of previa
– Complete previa = c/section
– Low lying = (probable attempted vaginaldelivery
– Marginal/partial = (it depends!)
Consider “double setup” for uncertain cases

DeliveryDelivery Immediate delivery of the fetus may be indicated if
the fetus is mature If the fetus or mother are in distress. Blood volume replacement (to maintain blood
pressure) and blood plasma replacement (to maintain fibrinogen levels) may be necessary in a bleeding episode
