Amniotic Fluid Embolism
Amniotic fluid embolism occurs when some amniotic fluid (the fluid that surrounds the fetus in the uterus) that contains cells or tissue from the fetus enters the woman’s bloodstream and causes a serious reaction in the woman. This reaction can damage the lungs and heart and cause excessive bleeding.
Amniotic fluid embolism is very rare.
Risk is increased when
The fluid or tissue can cause a serious reaction in the woman. She may have a rapid heart rate, an irregular heart rhythm, low blood pressure, and difficulty breathing. She may stop breathing (respiratory failure), or her heart may stop (cardiac arrest). About 13 to 44% of women with amniotic fluid embolism die.
Disseminated intravascular coagulation is a common complication. In this disorder, small blood clots develop throughout the bloodstream, resulting in massive loss of blood. Emergency care is required.
Prompt diagnosis and treatment of amniotic fluid embolism are essential. Doctors diagnose this problem based on symptoms, particularly when a woman has the following three symptoms:
Women may be given a transfusion of blood and blood components. Injection of a blood clotting factor (which helps blood clot) may be lifesaving. Women may require assistance with breathing or drugs to help the heart contract.
