![]() Because amniotic fluid embolisms are rare, it's difficult to identify risk factors. ![]() It's estimated that there are between one and 12 cases of amniotic fluid embolism for every 100,000 deliveries. ![]() It's not clear why in some mothers this leads to amniotic fluid embolism. However, amniotic fluid embolisms are rare - and it's likely that some amniotic fluid commonly enters the mother's bloodstream during delivery without causing problems. This can result in a serious blood-clotting disorder known as disseminated intravascular coagulation. When this breakdown happens, the immune system responds by releasing products that cause an inflammatory reaction, which activates abnormal clotting in the mother's lungs and blood vessels. A likely cause is a breakdown in the placental barrier, such as from trauma. Fetal distress, such as a slow heart rate, or other fetal heart rate abnormalitiesĪmniotic fluid embolism occurs when amniotic fluid or fetal material enters the mother's bloodstream.Rapid heart rate or disturbances in the rhythm of the heart rate.Altered mental status, such as anxiety or a sense of doom.Bleeding from the uterus, cesarean incision or intravenous (IV) sites.Life-threatening problems with blood clotting (disseminated intravascular coagulopathy).Sudden failure of the heart to effectively pump blood (cardiovascular collapse).Excess fluid in the lungs (pulmonary edema).SymptomsĪmniotic fluid embolism might develop suddenly and rapidly. If your doctor suspects you might have one, you'll need immediate treatment to prevent potentially life-threatening complications. Amniotic fluid embolism is most likely to occur during delivery or in the immediate postpartum period.Īmniotic fluid embolism is difficult to diagnose. Amniotic fluid embolism is a rare but serious condition that occurs when amniotic fluid - the fluid that surrounds a baby in the uterus during pregnancy - or fetal material, such as fetal cells, enters the mother's bloodstream.
