What is Placenta Previa?
Placenta previa is a condition characterized by the placenta being situated lower in the uterus than usual, sometimes even covering part or all of the cervix. This condition occurs in approximately 1 in 200 pregnancies. There are four types of placenta previa:
- Grade 1: The placenta is positioned low within the uterus.
- Grade 2: Marginal previa, where the placenta is near the cervix but not obstructing it.
- Grade 3: Partial previa, where the placenta covers part of the cervical opening.
- Grade 4: Complete previa, where the placenta fully covers the cervical opening.
Common symptoms include sudden, bright red vaginal bleeding during the latter half of pregnancy and contractions. The frequency of bleeding can vary; it may stop and then return later, often intensifying as the due date approaches.
What Causes Placenta Previa?
The exact cause of placenta previa remains unclear, but certain factors can increase the risk. According to the Mayo Clinic, these include:
- Previous pregnancies
- Uterine scars from surgeries like C-sections
- Having placenta previa in a prior pregnancy
- Carrying multiple fetuses
- Being over the age of 35
- Non-white race
- Smoking or cocaine use
Diagnosis typically occurs via ultrasound, either during routine check-ups or after episodes of bleeding.
Complications of Placenta Previa
Potential complications from placenta previa can affect both the mother and baby. The most significant risks include:
- Severe bleeding during labor or delivery
- Preterm birth, potentially necessitating an emergency C-section if bleeding is critical
If an early delivery is needed, it can pose risks to the baby, particularly if essential organs like the lungs have not fully developed.
Managing Placenta Previa
In some cases, the placenta may shift as the pregnancy progresses, resolving the condition. If not, the primary goal is to maintain the pregnancy until full term, with delivery typically via C-section. Management strategies may include:
- Activity reduction
- Bed rest
- Pelvic rest (no sexual intercourse, tampons, or douching)
- Blood transfusions if necessary
- Medications to delay labor
- Steroid shots to aid in fetal lung development
In severe cases, tocolytic medications may be used to prevent contractions. It’s crucial to avoid activities that could exacerbate the condition, such as heavy lifting or using vaginal products.
Precautions with Placenta Previa
If you have placenta previa, it’s vital to avoid certain activities:
- Refrain from vaginal intercourse after the 28-week mark.
- Avoid using tampons or douches.
- If spotting occurs, use pads and contact your doctor immediately.
- Avoid over-the-counter medications without doctor approval.
- Steer clear of heavy lifting.
Always keep your doctor informed if bleeding occurs again.
