Amniotic fluid embolism: despite progress, challenges remain.

Area of Science:

• Obstetrics and Gynecology
• Perinatology
• Critical Care Medicine

Background:

• Amniotic fluid embolism (AFE) is a rare obstetric emergency with high maternal morbidity and mortality.
• Incidence is approximately 7-8 per 100,000 births, making it a significant concern in maternal healthcare.

Purpose of the Study:

• To review the incidence, pathophysiology, risk factors, diagnosis, and management of amniotic fluid embolism (AFE).
• To highlight recent findings and current understanding of AFE's complex clinical presentation and treatment.

Main Methods:

• Literature review of existing studies on amniotic fluid embolism.
• Analysis of pathophysiology, clinical manifestations, diagnostic challenges, and therapeutic strategies.

Main Results:

• AFE involves an individual's response to fetal tissue, potentially mimicking septic shock.
• Clinical presentation includes acute dyspnea, cardiovascular collapse, coagulopathy, and neurological symptoms.
• Current diagnostic markers have limited clinical value due to rapid disease progression.

Conclusions:

• Early diagnosis and intervention are critical for improving maternal and fetal outcomes in AFE.
• Definitive diagnosis remains challenging, relying on clinical suspicion and limited data.
• Novel biomarkers are under investigation but lack sufficient early warning capabilities for real-time impact.
