Is there a risk of amniotic fluid embolism during vaginal delivery?

Generally, vaginal delivery carries a risk of amniotic fluid embolism. The detailed analysis is as follows:

Amniotic fluid embolism is a rare but severe complication that occurs during pregnancy or the process of childbirth. It refers to the entry of substances from the amniotic fluid into the maternal circulatory system, causing pulmonary vascular obstruction, which in turn leads to symptoms such as difficulty breathing, hypotension, and central nervous system dysfunction. There is a certain risk of this condition during vaginal delivery. Excessively strong uterine contractions and the labor process itself may increase the risk of amniotic fluid embolism. For example, contractions that are too frequent or too intense may increase the chance of amniotic fluid entering the maternal bloodstream. If a woman has previously experienced amniotic fluid embolism, her risk of recurrence in subsequent deliveries increases. In multiple pregnancies, the greater number of fetuses increases the likelihood of amniotic fluid components entering the maternal circulation. Polyhydramnios (excessive amniotic fluid) or increased infectious materials in the amniotic fluid may also elevate the risk of amniotic fluid embolism.

During vaginal delivery, it is important to closely monitor for potential complications, assess the mother's risk factors, and take appropriate measures when necessary to ensure the safety of both mother and baby.
