Amniotic fluid embolism occurs when amniotic fluid enters the maternal circulation, often leading to fatal complications for the mother, such as pulmonary artery blockages and disseminated intravascular coagulation (DIC). Symptoms may include respiratory distress, chest pain, and fetal distress, requiring immediate emergency interventions like oxygen administration and potential intubation. Key risk factors are advanced maternal age and placental issues, and the condition can result in severe outcomes such as maternal and infant death.
