Signs of Placenta previa (Placenta covers cervix)

Description

In placenta previa the placenta covers the cervix. Generally, the placenta is attached away from the cervix. Sometimes the growth of the uterus causes the placenta to move away from the cervix. Other times bleeding from the placenta can occur and can threaten the life of the fetus and the mother. The disorder is more common in older mothers, mothers with previous cesarean sections and in women with multiple previous childbirths.

Symptoms

Sudden painless vaginal bleeding, often heavy vaginal bleeding (often occurring near the end of the second trimester or beginning of the third trimester), uterine cramping, premature labor.

Tests

A history and physical exam will be performed. A pelvic ultrasound can diagnose placenta previa. Blood tests may be done if vaginal bleeding is involved.

Standard Workup

CBC
BHCG
Ultrasound

Treatment

Treatment depends on various factors including the amount of bleeding and the age of the fetus. Close monitoring in the hospital, transfusions and medications to stop labor are the standard treatment for fetuses less than 36 weeks. Beyond 36 weeks a C-section may be done. Bed rest and pelvic rest are advised for non-bleeding previas.
