Chorioamnionitis is a big word that describes an infection in the tissues surrounding the fetus during pregnancy. It can be serious for both the mother and the baby. In this article, we will break down what chorioamnionitis is, what causes it, its symptoms, how doctors diagnose it, treatments available, and ways to prevent it.
Chorioamnionitis happens when bacteria or other germs infect the tissues around the fetus in the womb. These tissues include the chorion and amnion, which are the membranes that surround the fetus and the amniotic fluid that protects the baby. This infection usually occurs during labor or delivery but can also happen earlier in pregnancy.
Types of Chorioamnionitis:
There are no specific types of chorioamnionitis, but it can be categorized based on the severity and extent of the infection.
Causes of Chorioamnionitis:
- Prolonged labor – When labor lasts too long, it increases the risk of infection.
- Premature rupture of membranes – When the amniotic sac breaks too early, bacteria can enter the womb.
- Multiple vaginal exams during labor – Each vaginal exam increases the risk of introducing bacteria into the womb.
- Group B streptococcus (GBS) infection – This common bacteria can cause chorioamnionitis if it spreads to the womb.
- Sexually transmitted infections (STIs) – Infections like chlamydia and gonorrhea can lead to chorioamnionitis if left untreated.
- Bacterial vaginosis – An imbalance of bacteria in the vagina can increase the risk of chorioamnionitis.
- Weakened immune system – Conditions like HIV/AIDS or undergoing chemotherapy can make the body more susceptible to infections.
- Invasive prenatal procedures – Certain prenatal tests or procedures may introduce bacteria into the womb.
- Fetal monitoring devices – Continuous fetal monitoring during labor may increase the risk of infection.
- Obesity – Being overweight or obese can increase the risk of infections during pregnancy.
- Diabetes – Poorly controlled diabetes can weaken the immune system and increase the risk of infections.
- Anemia – A lack of red blood cells can weaken the body’s defenses against infections.
- Smoking – Smoking during pregnancy can weaken the immune system and increase the risk of infections.
- Poor prenatal care – Lack of regular prenatal check-ups can lead to undetected infections.
- Membrane stripping – A procedure sometimes performed to induce labor can increase the risk of infection.
- Multiple pregnancies – Carrying more than one fetus can increase the risk of complications, including infections.
- Previous history of chorioamnionitis – Women who have had chorioamnionitis in a previous pregnancy are at higher risk in subsequent pregnancies.
- Urinary tract infections (UTIs) – Untreated UTIs can lead to ascending infections, reaching the womb.
- Intrauterine devices (IUDs) – Women with IUDs have a slightly increased risk of chorioamnionitis if they become pregnant.
- Poor hygiene practices – Not maintaining proper hygiene during pregnancy can increase the risk of infections.
Symptoms of Chorioamnionitis:
- Fever – A body temperature above 100.4°F (38°C) is a common symptom of chorioamnionitis.
- Rapid heart rate – Both the mother and the baby may have an increased heart rate.
- Rapid breathing – The mother may experience shortness of breath or increased respiratory rate.
- Foul-smelling amniotic fluid – The amniotic fluid may have a foul odor, often described as smelling like urine or feces.
- Uterine tenderness – The mother may feel pain or tenderness in the abdomen, especially over the uterus.
- Maternal malaise – The mother may feel generally unwell, fatigued, or achy.
- Abdominal pain – The mother may experience abdominal discomfort, cramping, or contractions.
- Vaginal discharge – The mother may notice an increase in vaginal discharge, which may be abnormal in color or consistency.
- Fetal distress – Changes in the baby’s heart rate or movement may indicate fetal distress.
- Chills – The mother may experience chills or shaking as the body tries to fight off the infection.
- Nausea and vomiting – Some women with chorioamnionitis may experience nausea and vomiting.
- Headache – Headaches can occur as a result of the fever and overall illness.
- Flu-like symptoms – Chorioamnionitis can mimic the symptoms of the flu, including body aches and fatigue.
- Decreased fetal movement – The mother may notice a decrease in the baby’s movements.
- Hypotension – Low blood pressure may occur in severe cases of chorioamnionitis.
- Confusion or disorientation – Severe infections can affect mental clarity and cognitive function.
- Jaundice in the newborn – If the baby is born with chorioamnionitis, they may develop jaundice due to liver dysfunction.
- Septicemia – In severe cases, chorioamnionitis can lead to bloodstream infections.
- Sepsis – Chorioamnionitis can progress to sepsis, a life-threatening condition characterized by systemic inflammation and organ dysfunction.
- Organ failure – In the most severe cases, chorioamnionitis can lead to multi-organ failure and death.
Diagnostic Tests for Chorioamnionitis:
- Medical history – The doctor will ask about symptoms, risk factors, and previous pregnancies.
- Physical examination – The doctor will assess vital signs, abdominal tenderness, and other signs of infection.
- Blood tests – Complete blood count (CBC) can show elevated white blood cell count, indicating infection.
- Urine tests – Urinalysis can detect urinary tract infections, which may contribute to chorioamnionitis.
- Amniocentesis – This test involves taking a sample of amniotic fluid to check for signs of infection.
- Fetal monitoring – Continuous monitoring of the baby’s heart rate can indicate fetal distress.
- Ultrasound – Ultrasound imaging can help visualize the fetus and assess amniotic fluid levels.
- C-reactive protein (CRP) – Elevated CRP levels in the blood may indicate inflammation due to infection.
- Procalcitonin – Elevated levels of procalcitonin can indicate bacterial infection.
- Maternal temperature – Monitoring the mother’s temperature regularly can help detect fever, a common sign of infection.
- Fetal blood sampling – In rare cases, fetal blood may be sampled to assess fetal well-being and detect infection.
- Cultures – Cultures of blood, urine, or amniotic fluid can identify the specific bacteria causing the infection.
- Non-stress test – This test monitors the baby’s heart rate in response to movement, indicating fetal well-being.
- Biophysical profile – A combination of ultrasound and fetal heart rate monitoring to assess fetal well-being.
- Magnetic resonance imaging (MRI) – MRI can provide detailed images of the womb and surrounding tissues.
Treatments for Chorioamnionitis:
Treating chorioamnionitis aims to eliminate infection, reduce maternal and fetal complications, and promote a safe delivery. Non-pharmacological treatments may include:
- Intravenous Fluids: Hydration is crucial during labor, especially if fever and dehydration occur.
- Antibiotics: Broad-spectrum antibiotics are usually administered intravenously to treat the infection and prevent complications.
- Oxygen Therapy: Supplemental oxygen may be provided to the mother if respiratory distress occurs.
- Fetal Monitoring: Continuous fetal heart rate monitoring helps assess fetal well-being and detect signs of distress.
- Intravenous Analgesia: Pain relief medications may be administered to manage discomfort during labor.
- Maternal Rest: Encouraging the mother to rest and conserve energy can support the labor process.
- Temperature Regulation: Cooling measures, such as damp cloths or fans, may help reduce fever and discomfort.
- Uterine Massage: Gentle massage of the uterus can help promote uterine contractions and progress labor.
- Emptying the Bladder: Catheterization may be necessary to ensure the bladder is empty, reducing pressure on the uterus.
- Positioning: Changing positions frequently can help relieve pain and promote optimal fetal positioning.
Drugs Used in the Treatment of Chorioamnionitis:
Several drugs may be used to manage chorioamnionitis and its complications:
- Antibiotics: Commonly prescribed antibiotics include ampicillin, gentamicin, and clindamycin.
- Tocolytics: These medications may be used to inhibit uterine contractions and delay delivery in preterm labor cases.
- Analgesics: Pain relief medications such as acetaminophen or ibuprofen may be given to alleviate discomfort.
- Antipyretics: Drugs like acetaminophen or ibuprofen can help reduce fever in infected individuals.
- Antiemetics: These medications may be used to control nausea and vomiting associated with chorioamnionitis.
- Intravenous Fluids: Solutions containing electrolytes and glucose help maintain hydration and electrolyte balance.
- Oxytocin: In some cases, synthetic oxytocin may be administered to induce or augment labor.
- Magnesium Sulfate: This medication is sometimes used to prevent or manage seizures in cases of severe preeclampsia or eclampsia.
- Steroids: Corticosteroids like betamethasone may be given to accelerate fetal lung maturity in preterm labor.
- Antihypertensives: Medications to lower blood pressure may be necessary in cases of severe hypertension or preeclampsia.
Surgeries for Chorioamnionitis:
In severe cases or when complications arise, surgical interventions may be required:
- Cesarean Section: If vaginal delivery poses risks to the mother or baby, a cesarean section may be performed to expedite delivery and reduce complications.
- Manual Removal of Placenta: In cases of retained placenta or placental fragments, manual extraction may be necessary to prevent infection.
- Exploratory Laparotomy: Rarely, surgical exploration of the abdomen may be required if there are concerns about maternal or fetal well-being.
Preventive Measures for Chorioamnionitis:
While chorioamnionitis cannot always be prevented, certain measures may reduce the risk:
- Prenatal Care: Regular prenatal check-ups allow healthcare providers to monitor for signs of infection and provide appropriate interventions.
- Hygiene Practices: Maintaining good personal hygiene, including regular handwashing, can help prevent the spread of infection.
- Avoiding Risky Behaviors: Practices such as smoking, drug use, and unprotected sex increase the risk of infection and should be avoided during pregnancy.
- Screening and Treatment of Infections: Screening for infections such as group B streptococcus during pregnancy allows for early detection and treatment, reducing the risk of chorioamnionitis.
- Prompt Treatment of Urinary Tract Infections: Treating urinary tract infections promptly can prevent ascending infections that may lead to chorioamnionitis.
- Preventing Premature Rupture of Membranes: Avoiding activities that increase the risk of premature rupture of membranes, such as heavy lifting or trauma, can help prevent infection.
- Healthy Lifestyle Choices: Eating a balanced diet, staying physically active, and maintaining a healthy weight can support overall maternal and fetal health.
