Amniotic fluid embolism, amniotic fluid embolism is a very serious complication in obstetrics. There is no way to predict amniotic fluid embolism in advance, which may occur in full-term normal delivery, cesarean section, or in induced labor; 3, post-partum infection, induced labor surgery process, if the aseptic operation is not very strict, it may lead to maternal intrauterine infection.
