Introduction
In general, amniotic fluid embolism can occur during vaginal delivery. Amniotic fluid embolism refers to a series of severe obstetric complications caused by the sudden entry of amniotic fluid into the maternal bloodstream during labor, leading to acute pulmonary embolism, anaphylactic shock, disseminated intravascular coagulation, renal failure, and other related conditions. During vaginal delivery, once the fetal membranes rupture, amniotic fluid may enter the maternal bloodstream.
In general, amniotic fluid embolism can occur during vaginal delivery. The specific analysis is as follows:
Amniotic fluid embolism refers to a series of severe obstetric complications caused by the sudden entry of amniotic fluid into the maternal bloodstream during labor, including acute pulmonary embolism, anaphylactic shock, disseminated intravascular coagulation, renal failure, and others. During vaginal delivery, once the fetal membranes rupture, amniotic fluid may enter the maternal bloodstream, thereby causing amniotic fluid embolism. For example, when uterine contractions are excessively strong, the pressure within the amniotic cavity increases, which may allow amniotic fluid to more easily enter the maternal circulation through blood vessels between the uterine wall and fetal membranes or through blood sinuses at the edge of the placenta. Due to the high risk of amniotic fluid embolism, immediate emergency treatment measures must be taken once symptoms appear.
Pregnant women should focus on maintaining emotional stability and avoid strenuous activity and excessive fatigue. Additionally, they should closely monitor physical changes and promptly communicate with their doctors if any unusual sensations or symptoms occur, to ensure safety and smooth progression during pregnancy and delivery.
