Amniotic fluid embolism, in obstetrics, is a very serious complication. According to statistics, it may occur once in every 2,000 to 3,000 births, and some hospitals count that it may be encountered only once in tens of thousands of births. So, which groups of people are prone to amniotic fluid embolism? The following is an introduction to the people who are prone to amniotic fluid embolism: 1, the use of oxytocin to induce labor and birth pain is very strong maternal: also more likely to occur amniotic fluid embolism. 2, advanced maternal age: that is, the age of more than 35 years old, the higher the chance of occurrence, the older the age, the greater the possibility of occurrence. 3.Patients with early placental abruption: In the process of delivery, if early placental abruption occurs, the possibility of fetal cells, fetal fat or fetal stool in the amniotic fluid entering the maternal blood through the placental vein will increase. 4. Pregnant women whose fetus dies in utero: The longer the fetus dies in utero, the higher the chance of amniotic fluid embolism. 5.When the fetus is in distress, the chance of amniotic fluid embolism is also higher. Because when the fetus is in distress, there is often fetal stool in the amniotic fluid, the labor pains are usually very strong at this time, and amniotic fluid embolism is more likely to occur. 6, the number of births: for example, the third, fourth or even seven or eight births, the more births, the higher the rate of amniotic fluid embolism. Note: Clinically, the following pregnant women are more likely to have amniotic fluid embolism, so you must be especially careful when you encounter this situation.
