Amniotic fluid embolism: diagnosis and management.

Area of Science:

• Obstetrics and Gynecology
• Critical Care Medicine
• Cardiology

Background:

• Amniotic fluid embolism (AFE) is a rare but catastrophic obstetric emergency.
• Prompt diagnosis and management are crucial for maternal and fetal survival.

Purpose of the Study:

• To establish evidence-based guidelines for the diagnosis and management of amniotic fluid embolism.
• To synthesize current evidence using the GRADE methodology.

Main Methods:

• A systematic literature review was conducted across major medical databases (MEDLINE, PubMed, EMBASE, Cochrane Library).
• English-language articles published from 1966 to March 2015 were prioritized, focusing on original research and randomized controlled trials.
• The GRADE system was employed to assess the quality of evidence and strength of recommendations.

Main Results:

• Amniotic fluid embolism should be considered in cases of sudden cardiorespiratory collapse in laboring or recently delivered women.
• No specific laboratory test can confirm or refute AFE; it remains a clinical diagnosis.
• Immediate high-quality cardiopulmonary resuscitation is recommended for cardiac arrest associated with AFE.

Conclusions:

• Immediate delivery (≥23 weeks gestation) is recommended following cardiac arrest due to AFE.
• Management includes adequate oxygenation, ventilation, vasopressors, inotropic agents, and avoidance of excessive fluid administration.
• Early assessment and aggressive management of coagulopathy using massive transfusion protocols are crucial.
