Pulmonary Emboli (Amniotic Fluid)
Overview
Plain-Language Overview
A Pulmonary Emboli (Amniotic Fluid) is a rare but serious condition that occurs when amniotic fluid, which surrounds a baby during pregnancy, enters the mother's bloodstream and blocks blood vessels in the lungs. This affects the respiratory system and can cause sudden difficulty breathing, low oxygen levels, and heart problems. The blockage prevents normal blood flow through the lungs, leading to shortness of breath, low blood pressure, and sometimes loss of consciousness. It usually happens during or shortly after childbirth, especially during labor or delivery. This condition requires immediate medical attention because it can rapidly worsen and affect the mother's overall health.
Clinical Definition
Pulmonary Emboli (Amniotic Fluid) is an acute, life-threatening obstetric emergency characterized by the entry of amniotic fluid, fetal cells, and debris into the maternal venous circulation, leading to obstruction of the pulmonary vasculature. The core pathology involves a sudden embolic event causing pulmonary hypertension, right ventricular failure, and systemic hypotension. It typically occurs during labor, delivery, or the immediate postpartum period. The pathophysiology includes an inflammatory response triggered by amniotic fluid components, resulting in disseminated intravascular coagulation (DIC) and severe hypoxemia. Clinically, it presents with respiratory distress, cardiovascular collapse, and coagulopathy. This syndrome is a major cause of maternal mortality worldwide and requires rapid recognition and supportive management.
