What is AFE in obstetrics?

Obstetrics. Pathophysiology of the amniotic fluid embolism. An amniotic fluid embolism (AFE) is a very uncommon childbirth ( obstetric) emergency in which amniotic fluid enters the blood stream of the mother to trigger a serious reaction.

How does AFE occur?

The disorder occurs during the last stages of labor when amniotic fluid enters the circulatory system of the mother via tears in the placental membrane or uterine vein rupture. Upon later analysis, fetal cells are found in the maternal circulation. When the fetal cells and amniotic fluid enter the bloodstream, reactions occur that cause severe changes in the mechanisms that affect blood clotting. Disseminated intravascular coagulation occurs and results in serious bleeding. The condition can also develop after elective abortion, amniocentesis, cesarean delivery or trauma. Small lacerations in the lower reproductive tract are associated with AFE.

What is AFE diagnosis?

Diagnosis. AFE is diagnosed when all other causes have been excluded. The presence of fetal squamous cells or other fetal tissues, including meconium, have been found in the maternal circulation after the event. Diagnosis is also based upon the signs and symptoms observed during the birth or procedures.

What age is associated with AFE?

According to one study, induction of labor may double the risk of AFE. However, other studies have refuted this claim. A maternal age of 35 years or older is associated with AFE.

How many times has the complication of a syringe been recorded?

This rare complication has been recorded seventeen times prior to 1950. The complication was originally described in 1926 by J. R. Meyer at the University of Sao Paulo. A 1941 case study of eight autopsies of pregnant women who died suddenly during childbirth by Clarence Lushbaugh and Paul Steiner enabled widespread recognition of the diagnosis within the medical community, and was eventually republished as a landmark paper in the Journal of the American Medical Association.

Why is amniotic fluid embolism a condition?

Amniotic fluid embolism is a condition that occurs because there is systemic reaction similar to that found in an allergic response to amniotic fluid or fetal cells or fetal tissue debris by the pregnant mother.

How to tell if you have amniotic fluid embolism?

Other common initial symptoms include difficulty breathing or shortness of breath (dyspnea), abnormally rapid breathing (tachypnea), low blood pressure (hypotension), an abnormally rapid heartbeat (tachycardia), bluish discoloration of the skin and mucous membranes due to a lack of oxygen (cyanosis) in the blood, and a deficiency in the amount of oxygen reaching the tissues of the body (hypoxia). There may be rapidly high blood pressure in the blood vessels of the lungs (pulmonary hypertension) and sudden narrowing of blood vessels (vasospasm).

What is the diagnosis of amniotic fluid embolism?

A diagnosis of amniotic fluid embolism is based upon identification of characteristic clinical symptoms only. To date, there are no diagnostic assays, imaging studies or pathologic markers that have been validated for the diagnosis of AFE. Prompt diagnosis and early, aggressive advanced life support techniques are essential in assuring the best possible outcomes in amniotic fluid embolism. There is a lack of internal consensus in the medical community as to diagnostic criteria for this disorder, although there have been proposed diagnostic criteria for the research reporting of AFE (Clark SL, 2016). The diagnosis is made by identifying characteristic symptoms and excluding other possible causes of the signs and symptoms (diagnosis of exclusion).

What is AFE in pregnancy?

Amniotic fluid embolism (AFE) is an extremely rare, but life-threatening complication that affects pregnant women shortly before, during, or immediately following labor and childbirth.

What are the complications of amniotic fluid?

Breathing problems, cardiac arrest, and excessive bleeding are some of the life-threatening complications that can occur. Researchers and physicians do not fully understand why amniotic fluid or fetal cells entering the mother’s bloodstream causes this reaction in some women.

Why does amniotic fluid enter the bloodstream?

The amniotic fluid and other material enters the mother’s bloodstream, most likely due to small tears in the lower part of the uterus, the part of the cervix that forms a canal connecting the vagina to the uterus (endocervix), or because of damage or abnormality affecting the placenta.

How many women have a fluid embolism?

Rare disorders often go unrecognized or misdiagnosed, making it difficult to determine their true frequency in the general population. Estimates have ranged from 1 in 8,000 to 1 in 80,000 pregnancies.

Signs

The signs and symptoms of amniotic fluid embolism can sometimes overlap with other childbirth complications, making it difficult to recognize.

Causes

The exact causes of amniotic fluid embolism are still unknown because it is so rare.

Diagnosis

It is hard for doctors to diagnose amniotic fluid embolism because the symptoms are similar to other childbirth-related complications. Additionally, there is no specific test to diagnose the condition, which means that other conditions will need to be ruled out first.

Treatment

If your doctor suspects you could have an amniotic fluid embolism, you’ll need immediate emergency treatment to prevent potentially life-threatening complications.

Complications

Amniotic fluid embolism can cause serious complications for a pregnant person and their baby. These life-threatening complications can include:

Risk Factors

Experts do not know for sure why amniotic fluid embolism happens. Research points to a few factors that might be linked to an increased risk of experiencing the condition.

When does AFE occur?

AFE occurs when the amniotic fluid or fetal material passes the placental barrier, enters the mother's bloodstream and starts moving throughout the circulatory system.

What happens if a baby is deprived of oxygen for too long?

Infant death: If the baby is deprived of oxygen for too long or is not delivered quickly enough, the baby can die during delivery. Sudden cardiac arrest: The effects of AFE can develop so rapidly that the blood clots in the lungs send the mother into cardiac arrest.

How many mothers die from AFE?

The effects of AFE can be devastating. The maternal mortality rate for this condition can be as high as 80%, with 50% of mothers dying within the first hour of symptom onset. For patients that do survive the embolism, the majority of them will experience long-term neurological deficits.

What happens if you have an AFE?

Still, there are several complications that can occur from AFE: Brain injury to mother: The blood clots in the lungs from the embolism can reduce the amount of oxygen traveling to the mother's brain, which can result in permanent brain damage.
