What are the main causes of water embolism?

First: during childbirth, after the start of the labor process, the effective rhythmic contractions constantly stretch the cervix, making it shorter, flattened and gradually expanded. At the same time, the separation of the fetal membrane and the uterine wall of the pregnant mother will lead to the rupture of the cervical venule.

Second: when the fetal membrane is naturally or artificially ruptured, amniotic fluid can enter between the decidual tissue and the uterine wall through the ruptured fetal membrane. When the uterus shrinks and baby first appears close to the cervix, the pressure in the amniotic cavity is too high, and it can also enter the circulation of the mother through this way.

Third: in addition, in the process of some invasive examination or treatment, there are also times when amniotic fluid and maternal blood meet, such as amniocentesis, umbilical cord blood puncture, uterine curettage with large gestational age, etc.
