Amniotic fluid embolism is more frequent in normal labor than in cesarean section, with 70% occurring during normal labor via vaginal delivery and 19% occurring during cesarean section. In normal labor, amniotic fluid suddenly ruptures due to overly strong contractions, and amniotic fluid may be squeezed into the broken microvessels and enter the mother’s blood circulation, resulting in amniotic fluid embolism; in cesarean section, the amniotic fluid is broken under human manipulation, and the amniotic cavity will have less tension, so the incidence of amniotic fluid embolism is comparatively lower. Amniotic fluid embolism has certain high-risk factors, and its incidence is very high, including advanced age, multiple pregnancies, menstruation, excessive amniotic fluid, improper use of contractions during labor, too strong contractions, too frequent contractions, and improper manual rupture of membranes, etc. Therefore, it is important to learn from the experience of preventing high-risk factors, such as not exceeding the 35th year of age in an age-appropriate pregnancy. In addition, pay attention to the fetus during pregnancy not to be too large, not too much amniotic fluid, in labor and delivery to pay attention to the contractions not to be too frequent, if one’s contractions are too frequent or too strong, must promptly reflect with the doctor, the use of uterine contraction inhibitors static suppression of contractions, to prevent the occurrence of amniotic fluid embolism.
