An 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 hair, enters the maternal bloodstream.

An amniotic fluid embolism is most likely to occur during childbirth or immediately afterward.

An amniotic fluid embolism is difficult to diagnose. If your doctor suspects you might have an amniotic fluid embolism, you'll need immediate treatment to prevent potentially life-threatening complications.
