How is amniotic fluid embolism detected?
Diagnosis
- Blood tests, including those that evaluate clotting, heart enzymes, electrolytes and blood type, as well as a complete blood count (CBC)
- Electrocardiogram (ECG or EKG) to evaluate your heart’s rhythm.
- Pulse oximetry to check the amount of oxygen in your blood.
- Chest X-ray to look for fluid around your heart.
Which of the following signs and symptoms indicates amniotic fluid embolism?
Sudden shortness of breath. Excess fluid in the lungs (pulmonary edema) Sudden low blood pressure. Sudden failure of the heart to effectively pump blood (cardiovascular collapse)
What diseases differentiate with amniotic fluid embolism?
Differential Diagnoses
- Abruptio Placentae.
- Anaphylaxis.
- Aortic Dissection.
- Aspiration.
- Cholesterol Embolism.
- Myocardial Infarction.
- Pulmonary Embolism (PE)
- Septic Shock.
Does amniotic fluid embolism cause DIC?
An amniotic fluid embolism (AFE) is a rare, lethal syndrome that is commonly associated with disseminated intravascular coagulation (DIC). Anticoagulation therapy is the most important strategy to inhibit excessive activation of the coagulation cascade in patients with AFE and DIC.
How fast does amniotic fluid embolism happen?
Amniotic fluid embolism is thought to occur in labor or within 30 minutes of delivery. There are several signs and phases of amniotic fluid embolism.
Should I worry about amniotic fluid embolism?
An amniotic fluid embolism can cause potentially life-threatening breathing and heart issues, as well as uncontrolled bleeding. It is an often fatal emergency that requires immediate medical care for both the pregnant person and the baby.
When does amniotic fluid embolism occur?
Amniotic fluid embolism is thought to occur in labor or within 30 minutes of delivery.
How do you treat AFE?
Treatment is supportive and includes the following:
- Administer oxygen to maintain normal saturation.
- Initiate cardiopulmonary resuscitation (CPR) if the patient arrests.
- Treat hypotension with crystalloid and blood products.
- Avoid excessive fluid administration.
How common is AFE in pregnancy?
AFE is rare. Though estimates vary, the AFE Foundation reports the condition occurs in only 1 out of every 40,000 deliveries in North America (and 1 in every 53,800 deliveries in Europe). However, it’s a leading cause of death during labor or shortly after birth.
What is the mortality rate of amniotic fluid embolism?
Conclusion: The AFE mortality rate in population-based studies varied from 11% to 44% with the best available evidence supporting an overall mortality rate of 20.4%.
Can AFE be avoided?
AFE can’t be prevented, and it’s challenging for healthcare providers to predict if and when it will occur. If you’ve had AFE and planning to have another baby, it’s recommended that you talk to a high-risk obstetrician first.
How is AFE treated?
Hemodialysis with plasmapheresis and extracorporeal membrane oxygenation (ECMO) with intra-aortic balloon counterpulsation have been described in case reports with successful outcomes in treating AFE patients with cardiovascular collapse. The use of anticoagulation during ECMO may worsen bleeding in patients with AFE.
Can AFE be prevented?
AFE is a negative reaction that occurs when amniotic fluid enters your circulatory system. It can’t be prevented, and the reason why this reaction occurs is unknown.
