AI summary — for doctors, generated from the abstract only
This comprehensive review highlights that amniotic fluid embolism remains difficult to diagnose due to nonspecific early symptoms and a lack of definitive diagnostic protocols, contributing to its status as a leading cause of maternal mortality.
What was studied
A literature review (using PubMed and other sources) synthesizing historical perspectives, pathophysiology, diagnosis, and management of amniotic fluid embolism (AFE), aiming to improve awareness, early recognition, and understanding of outcomes including potential long-term complications in affected infants.
Key findings
- AFE is described as one of the leading causes of maternal mortality and morbidity.
- Misdiagnosis is noted as prevalent due to a lack of definitive diagnostic protocols for AFE.
- The review states that while new diagnostic methods are available, further study is needed to confirm their sensitivity.
- Not reported in the abstract: specific incidence rates, mortality percentages, or diagnostic test performance statistics.
Clinical relevance
The findings suggest that clinicians should maintain a high index of suspicion for AFE given its nonspecific early presentation, as prompt recognition and intervention are associated with better maternal and fetal outcomes, according to the review.
Who should care
Limitations
As a narrative literature review, the abstract does not report a systematic methodology for study selection or quality assessment, and the authors explicitly state further research is needed to understand AFE's mechanism and presentation.
Amniotic fluid embolism remains a diagnostic challenge with no definitive protocol, so early clinical suspicion and prompt intervention are critical to improving outcomes.

Abstract
Importance
Amniotic fluid embolism is a serious complication of pregnancy where fetal cells, amniotic fluid, and debris enter the maternal circulation, leading to cardiovascular collapse, respiratory issues, and disseminated intravascular coagulation, which can cause acute hemorrhage. Although the exact cause of this embolization is unknown, it frequently occurs in healthy women during pregnancy, after obstetric procedures, or within 48 hours after delivery. Early symptoms of amniotic fluid embolism are often nonspecific, potentially leading to misdiagnosis and increased maternal mortality and morbidity.
Objective
The goal of this review is to synthesize the current literature on early diagnosis methods, increase awareness and understanding of AFE, and ultimately improve outcomes for mothers and their babies. The importance of early recognition and intervention is also highlighted, as well as the potential for long-term complications such as cognitive disabilities in affected infants.
Evidence acquisition
We conducted a literature review and highlighted articles that pertained to the historical perspectives of the disease, its pathophysiology, diagnosis, and management. Sources, including PubMed, were used as search engines, and applicable articles were cited as references.
Results
AFE is one of the leading causes of maternal mortality and morbidity, as misdiagnosis is prevalent due to a lack of definitive diagnostic protocols for AFE. While new diagnostic methods are available, further study is needed to ensure that disease sensitivity is accurate.
Conclusions and relevance
Further research is needed to understand the mechanism and presentation of AFE, as prompt intervention is associated with positive maternal and fetal outcomes.
