http://emedicine.medscape.com/article/253068-overview Background Amniotic fluid embolism (AFE) is a rare obstetric emergency in which it is postulated that amniotic fluid, fetal cells, hair, or other debris enter the maternal circulation, causing cardiorespiratory collapse. In 1941, Steiner and Luschbaugh described AFE for the first time after they found fetal debris in the pulmonary circulation of women who died during labor. Current data from the National Amniotic Fluid Embolus Registry suggest that the process is more similar to anaphylaxis than to embolism, and the term *anaphylactoid syndrome of pregnancy* has been suggested because fetal tissue or amniotic fluid components are not universally found in women who present with signs and symptoms attributable to AFE.1<javascript:showcontent('active','references');> <javascript:showcontent('active','references');> The diagnosis of AFE has traditionally been made at autopsy when fetal squamous cells are found in the maternal pulmonary circulation; however, fetal squamous cells are commonly found in the circulation of laboring patients who do not develop the syndrome. In a patient who is critically ill, a sample obtained by aspiration of the distal port of a pulmonary artery catheter that contains fetal squamous cells is considered suggestive of but not diagnostic of AFE syndrome.2<javascript:showcontent('active','references');> <javascript:showcontent('active','references');>The diagnosis is essentially one of exclusion based on clinical presentation. Other causes of hemodynamic instability should not be neglected. For related information on pregnancy, see Medscape's Pregnancy<http://www.medscape.com/resource/pregnancy>Resource Center. Pathophysiology The pathophysiology of AFE is poorly understood. Based on the original description, it was theorized that amniotic fluid and fetal cells enter the maternal circulation, possibly triggering an anaphylactic reaction to fetal antigens. However, fetal material is not always found in the maternal circulation in patients with AFE, and material of fetal origin is often found in women who do not develop AFE. Benson et al3 <javascript:showcontent('active','references');> <javascript:showcontent('active','references');>tested 2 hypotheses concerning the pathophysiology of AFE: (1) Clinical symptoms result from mast cell degranulation with the release of histamine and tryptase, or (2) Clinical symptoms result from activation of the complement pathway. Nine women with AFE were compared with 22 women with normal labors. Serum from patients with AFE was collected within 14 hours of symptom onset and frozen. Urine was collected within 12-24 hours after symptom onset. Control patients had complement levels measured on admission, during labor, and the day after delivery. Six of the 9 women with AFE died, and all 9 required blood transfusions for disseminated intravascular coagulation (DIC). Seven women had no evidence of mast cell degranulation (ie, either urinary histamine or serum tryptase). Compared with postpartum control patients, complement levels in the AFE group were severely depressed. C3 in the AFE group was 44 compared with 117.2 in the postpartum group. C4 was 10.7 in the AFE group versus 29.4 in the postpartum group. These differences were statistically significant. This suggests that complement activation may play an important role in the pathophysiology of AFE. Farrar and Gherman4 <javascript:showcontent('active','references');> <javascript:showcontent('active','references');>reported the case of a 40-year-old multipara in active labor with acute onset of facial erythema, seizures, hypoxia, cardiac arrest, DIC, and ultimately death. Fetal squames and fibrin thrombi were found in the pulmonary tree at autopsy. Blood drawn 2 hours after symptom onset had a serum tryptase level of 4.7 ng/mL (normal <1 ng/mL). A case reported by Marcus et al5<javascript:showcontent('active','references');> <javascript:showcontent('active','references');>, in which AFE developed after a spontaneous rupture of membranes, demonstrated no increase in mast cells or degranulation in lung tissue as shown by Giemsa staining. Serum tryptase levels were 11.4 ng/mL (normal <11.4 ng/mL). The initiating event is poorly understood. However, usually during labor or other procedure, amniotic fluid and debris, or some as yet unidentified substance, enters the maternal circulation; this may trigger a massive anaphylactic reaction, activation of the complement cascade, or both. Progression usually occurs in 2 phases. In phase I, pulmonary artery vasospasm with pulmonary hypertension and elevated right ventricular pressure cause hypoxia. Hypoxia causes myocardial capillary damage and pulmonary capillary damage, left heart failure, and acute respiratory distress syndrome. Women who survive these events may enter phase II. This is a hemorrhagic phase characterized by massive hemorrhage with uterine atony and DIC; however, fatal consumptive coagulopathy may be the initial presentation. Frequency United States Incidence of AFE is estimated at 1 case per 8,000-30,000 pregnancies. The true incidence is unknown because of inaccurate diagnoses and inconsistent reporting of nonfatal cases. International Incidence is similar to that of the United States. Mortality/Morbidity - Maternal mortality approaches 80%. - Mortality was 61% in the US national registry, which listed 46 cases. - AFE is the cause of 5-10% of maternal mortality in the United States. - Of patients with AFE, 50% die within the first hour of onset of symptoms. Of survivors of the initial cardiorespiratory phase, 50% develop a coagulopathy. - A population-based study using the California Office of Statewide Planning and Development database reviewed 1,094,248 deliveries over a 2-year period. Of 53 cases of AFE, 14 patients (26.4%) died and 35 patients (66%) developed DIC.6 <javascript:showcontent('active','references');> <javascript:showcontent('active','references');> - The United Kingdom AFE registry reports a mortality of 37%. Of those who survived AFE, 7% were neurologically impaired.7<javascript:showcontent('active','references');> <javascript:showcontent('active','references');> - Survival is uncommon, although the prognosis is improved with early recognition and prompt resuscitation. Most women who survive have permanent neurologic impairment. Neonatal survival was 79% in the US registry and 78% in the UK registry. Race No racial or ethnic predilection exists. Sex AFE only occurs in women. Age Advanced maternal age may be a risk factor. No relationship to age has been found in the National Amniotic Fluid Embolus Registry; however, at least one study has noted an increased incidence in women aged 30 years and older.8<javascript:showcontent('active','references');> <javascript:showcontent('active','references');> Clinical History Amniotic fluid embolism (AFE) usually occurs during labor but has occurred during abortion, after abdominal trauma, and during amnioinfusion. A woman in the late stages of labor becomes acutely dyspneic with hypotension; she may experience seizures quickly followed by cardiac arrest. Massive DIC-associated hemorrhage follows and then death. Most patients die within an hour of onset. Currently no definitive diagnostic test exists. The United States and United Kingdom AFE registries recommend the following 4 criteria, all of which must be present to make the diagnosis of AFE.7<javascript:showcontent('active','references');> ,1 <javascript:showcontent('active','references');>,9<javascript:showcontent('active','references');> <javascript:showcontent('active','references');> 1. Acute hypotension or cardiac arrest 2. Acute hypoxia 3. Coagulopathy or severe hemorrhage in the absence of other explanations 4. All of these occurring during labor, cesarean delivery<https://mail.google.com/article/263424-overview>, dilation and evacuation, or within 30 minutes postpartum with no other explanation of findings Physical In case reports, patients are described as developing acute shortness of breath, sometimes with a cough, followed by severe hypotension. The following signs and symptoms are indicative of possible AFE: - Hypotension: Blood pressure may drop significantly with loss of diastolic measurement. - Dyspnea: Labored breathing and tachypnea may occur. - Seizure: Tonic clonic seizures are seen in 50% of patients. - Cough: This is usually a manifestation of dyspnea. - Cyanosis: As hypoxia/hypoxemia progresses, circumoral and peripheral cyanosis and changes in mucous membranes may manifest. - Fetal bradycardia: In response to the hypoxic insult, fetal heart rate may drop to less than 110 beats per minute (bpm). If this drop lasts for 10 minutes or more, it is a bradycardia. A rate of 60 bpm or less over 3-5 minutes may indicate a terminal bradycardia. - Pulmonary edema: This is usually identified on chest radiograph. - Cardiac arrest - Uterine atony: Uterine atony usually results in excessive bleeding after delivery. Failure of the uterus to become firm with bimanual massage is diagnostic. - Coagulopathy or severe hemorrhage in absence of other explanation (DIC occurs in 83% of patients.)9<javascript:showcontent('active','references');> <javascript:showcontent('active','references');> - Altered mental status/confusion/agitation Causes AFE is considered an unpredictable and unpreventable event with an unknown cause. In the national registry, 41% of patients had a history of allergies. Reported risk factors for development of AFE include multiparity, advanced maternal age, male fetus, and trauma. In a retrospective review of a 12-year period encompassing 180 cases of AFE, of which 24 were fatal, medical induction of labor increased the risk of AFE.10<javascript:showcontent('active','references');> <javascript:showcontent('active','references');>In the same study, AFE was positively associated with multiparity, cesarean section or operative vaginal delivery, abruption, placenta previa, and cervical laceration or uterine rupture. 2010/9/15 Dwi Chahya <d...@sumitronics.co.id> > Mom & Dad, > > Pagi ini dapat cerita dari temen, sodaranya bis ngelahirin sempet koma & > terus akhirnya meninggal di lebaran ke-2. > > Usianya 42 thn, kehamilannya yg ke-3 ini gak disengaja, cos masih dalam > keadaan KB Spiral. > > Jadi tau2 pas periksa sudah hamil 4 bln.
