Amniotic fluid embolism: a report of four probable cases
Canadian Anaesthetists' Society Journal
|May 1, 1986
Summary
Amniotic fluid embolism (AFE) outcomes depend on insult severity and gestation, not solely on management. Early labor AFE cases had poor outcomes, while second-trimester D&C cases recovered fully.
Area of Science:
- Obstetrics and Gynecology
- Critical Care Medicine
- Hematology
Background:
- Amniotic fluid embolism (AFE) is a rare but catastrophic obstetric emergency.
- Understanding AFE's presentation and prognosis is crucial for timely intervention.
Observation:
- Reviewed four probable AFE cases: two during early labor, two during second-trimester dilatation and curettage (D&C).
- Early labor AFE cases resulted in non-recovery or severe neurological damage.
- Second-trimester D&C AFE cases, despite delayed disseminated intravascular coagulation (DIC), achieved full recovery.
Findings:
- Outcome correlated with insult severity and gestational age, not AFE management.
- Disseminated intravascular coagulation (DIC) occurred in all cases, manifesting earlier in labor-associated AFE.
- Unexplained collapse during second-trimester D&C warrants suspicion for AFE.
Implications:
- AFE can occur during seemingly uncomplicated labor or second-trimester D&C.
- Prompt transfer to specialized centers is vital for patients with suspected AFE and DIC post-D&C.
- Gestational age and insult severity are key prognostic indicators in AFE management.

01:25Pleural Effusion I: Introduction
Pleural effusion is an abnormal fluid accumulation in the pleural cavity, a narrow space between the lungs and the chest wall. It is not a disease per se but rather a symptom or indication of an underlying disease. In normal circumstances, this space contains a small amount of fluid (5 to 15 mL), a lubricant facilitating the non-frictional movement of the pleural surfaces.
There are two main types of pleural effusion: transudative and exudative. They are differentiated using Light's criteria,...

01:29Pulmonary Embolism I: Introduction
Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...
01:29Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care
Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...
01:18Viral Meningitis
Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...
01:19Cerebral Edema l: Introduction
Cerebral edema is a pathological increase in brain water content that disrupts intracranial pressure regulation and impairs neurological function. Because the cranial vault is rigid, even modest increases in tissue volume can compromise cerebral perfusion, distort neural structures, and initiate secondary injury. Cerebral edema develops through four principal mechanisms: vasogenic, cytotoxic, interstitial, and ionic.Vasogenic EdemaVasogenic edema arises from disruption of the blood–brain...
01:22Cerebral Edema ll: Pathophysiology
Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this barrier loses...
