Chorioamnionitis (chor-y-oh-am-nee-oh-NY-tis) is an infection of the placenta and the amniotic fluid. Only a few women get it, but, it is a common cause of preterm labor and delivery.
Chorioamnionitis is most often caused by bacteria commonly found in the vagina. It happens more often when the bag of waters (amniotic sac) is broken for a long time before birth. This lets bacteria in the vagina move up into the uterus.
You are more likely to have this infection if:
Your bag of waters (amniotic sac) breaks long before you actually deliver
You have a long labor
You have frequent vaginal exams during labor
This is your first pregnancy
You have a sexually transmitted infection or other vaginal infection
You use alcohol or tobacco
You have internal fetal monitoring
You get epidural anesthesia during labor
You have group B strep
Symptoms may be a little different for each person. They may include:
Fast heart rate in mother and baby
Sore or painful uterus
A bad smell from the amniotic fluid
The symptoms of chorioamnionitis can seem like other health problems. Always see your healthcare provider for a diagnosis.
Your provider will ask about your past health. He or she will give you a physical exam. He or she may be able to diagnose chorioamnionitis just by your symptoms. You may also need a lab test to check for infection.
Your healthcare provider may suggest a test called amniocentesis, although this test is not routinely done for chorioamnionitis. During this test, your healthcare provider uses a needle to take a small amount of amniotic fluid for testing.
Treatment will depend on your symptoms, age, and general health. It will also depend on how severe the condition is.
Antibiotics are used to treat chorioamnionitis as soon as the infection is found. Your healthcare provider may encourage you to deliver your baby early. This can prevent complications for you and your baby. You may need to keep taking antibiotics after your baby is born.
Chorioamnionitis can cause a dangerous blood infection in the mother called bacteremia. This can cause the baby to be born early. It can also cause serious complications in the newborn. This includes infection (such as pneumonia or meningitis), brain damage, or death.
If your bag of waters breaks early (premature rupture of membranes), antibiotics lowers the chance of chorioamnionitis. It is also helps to limit the number of vaginal exams before and during labor.
If your membranes rupture, tell your healthcare provider right away. Other symptoms that call for urgent care include:
Fast heart rate
Bad-smelling amniotic fluid

You may be given antibiotics if you have premature rupture of the membranes. This can reduce the risk for chorioamnionitis.
