Amniotic fluid embolism

Amniotic fluid embolism means that during delivery, the contents of amniotic fluid such as fetal fat, keratinized epithelial cells, meconium, and hairs enter the maternal blood circulation, forming emboli to block pulmonary blood vessels, resulting in maternal shock, bleeding, and diffuse intravascular coagulation DIC) and a series of severe symptoms. Sudden onset, dangerous illness and high mortality. The cause is mostly uterine contraction or rigidity, high intrauterine pressure, shortly after the rupture or rupture of the fetal membrane, amniotic fluid caused by the lacerated endometrial vein into the mother's blood circulation. Sudden emergence of unexplained dyspnea, cyanosis, shock, massive uterine bleeding, etc. during delivery should be suspected as the disease. Treatment includes anti-allergy, oxygen supply, relief of pulmonary hypertension, blood volume supplementation, anti-shock, and correction of DIC. If the fetus is not delivered, the delivery should end immediately. Amniotic fluid embolism is urgent, dangerous, and more than a short time after the onset of death. Avoiding evoking factors, timely diagnosis, and early rescue and treatment is the key to rescue survival.
