Which management is appropriate for placenta previa in an asymptomatic patient?

• A. Immediate vaginal delivery
• B. No vaginal examination, tocolytics, betamethasone for lung maturity; expectant management if asymptomatic
• C. Bed rest only
• D. Immediate cesarean delivery in all cases

Answer: (B)

When placenta previa is present but the patient is asymptomatic, the safest approach is to avoid manipulating the cervix and to manage expectantly. The placenta over the cervical os makes vaginal examination risky because contact with the os can trigger heavy vaginal bleeding from placental separation. Therefore, no vaginal examination is performed. Tocolytics are not routinely used in this scenario; they are reserved for preterm labor to delay delivery when continuing the pregnancy is beneficial. If contractions or preterm labor occur, tocolysis might be considered, but not as a standard measure for an asymptomatic previa. Betamethasone for fetal lung maturity is given only if preterm delivery is anticipated. If the pregnancy can continue toward term without bleeding, such steroids are not routinely administered. Expectant management means close monitoring and planning for delivery by cesarean when indicated by gestational age, bleeding, or placenta location, rather than attempting vaginal delivery in the presence of placenta previa. This combination—no vaginal exam, no routine tocolysis, steroids only if preterm delivery is likely, and expectant management if asymptomatic—best aligns with safely handling placenta previa in an asymptomatic patient.
