Cesarean section is more likely to cause amniotic fluid embolism than normal delivery. The sudden entry of amniotic fluid into the mother’s blood circulation during delivery can cause a series of critical symptoms, leading to anaphylactic shock, diffuse intravascular coagulation, renal failure and other symptoms in the mother. The delivery of a fetus by cesarean section requires incision of the belly and uterus of the pregnant woman, and the incision will be more, and the blood vessels at the incision will cause dissection, and the amniotic fluid may enter the blood vessels through the dissection and cause amniotic fluid embolism. If the baby is delivered by normal delivery, there will be fewer incisions in the vaginal delivery, and the chance of amniotic fluid entering the blood vessels and causing embolism will be smaller.
