Chorioamnionitis is an infection. It occurs in the membranes that surround the fetus. These membranes are called the chorion and the amnion. It is also an infection of the amniotic fluid. This fluid surrounds the fetus and protects it.
Chorioamnionitis can be a very serious condition. It requires special care from the doctor. A pregnant woman will need to deliver her baby right away. This is for the health of both the mother and the baby.
Bacterial infections usually cause this condition. Infection may begin in the mother’s genital tract. Bacteria then move up from the vagina, through the cervix, and into the fetal membranes. It then moves into the amniotic sac and its fluid. There it can then pass to the fetus. Many types of bacteria may cause this infection.
Chorioamnionitis is more common in young women. Other factors that can increase your chance of developing chorioamnionitis include:
Symptoms may include:
Your doctor will ask about your symptoms and medical history. A physical exam will be done. Your bodily fluid may need to be tested. This can be done with blood tests or amniocentesis.
The fetal heart rate will be monitored. The heart rate will increase if the mother has an infection.
The baby will need to be delivered. A
may be needed if:
Antibiotics will be delivered by IV into the mother's veins. The baby will get antibiotics if there is an infection present after birth.
