Hematologic problems associated with eclampsia can include decreased plasma volume, increased blood viscosity, hemoconcentration, and coagulopathy. Patients with eclampsia require immediate obstetric consultation and admission to a labor and delivery unit capable of providing intensive care until delivery of the neonate. This suggests that closely monitoring patients with these symptoms may provide an early warning for eclampsia. Am J Obstet Gynecol. [Medline]. [Medline]. In addition, rule out hypoglycemia as cause of seizure or result of seizure, and rule out hyperglycemia as a cause of mental status changes. Eclampsia can occur during the antepartum, intrapartum, and postpartum periods. If measured early in the second trimester, an ACR of 35.5 mg/mmol or higher may predict preeclampsia before symptoms arise. Etiologic and Risk Factors for Preeclampsia/Eclampsia, American Association for the Advancement of Science, American College of Obstetricians and Gynecologists, American Federation for Clinical Research, American Gynecological and Obstetrical Society, Association of Professors of Gynecology and Obstetrics, Christian Medical and Dental Associations, American Institute of Ultrasound in Medicine, Recent recommendations suggest that magnesium sulfate be utilized for seizure prophylaxis in severe preeclampsia and for controlling seizures in eclampsia, though magnesium sulfate is not required for preeclampsia without severe features.

She should also be educated on the importance of adequate prenatal care in subsequent pregnancies. [Medline]. IV fluids should be limited to isotonic solutions to replace urine output plus about 700 mL/d to replace insensible losses. It is believed that these changes are due to the interaction between fetal and maternal allografts and result in systemic and local vascular changes. [2]. The study also found a particularly high risk of maternal death at 20-28 weeksâ gestation. 2015 Apr. The Clinical Practice of Emergency Medicine.

Pregnancy-related mortality from preeclampsia and eclampsia. Adequate maternal pain relief for labor and delivery is vital and may be provided with either systemic opioids or epidural anesthesia. von Dadelszen P, Payne B, Li J, et al. Transitory fetal tachycardia may occur following the bradycardia. [Medline]. It has been proven that patients with elevated antiphospholipid plasma levels have a higher incidence of preeclampsia and eclampsia. 2013 Jun. The patient should be stabilized with respect to seizures, oxygenation, and hemodynamic status before the initiation of cesarean delivery. [Full Text]. Follow up 1-2 weeks after delivery to evaluate the patient for BP control and any residual deficits from the eclamptic seizure. What are potential complications of eclampsia? [5] Genetic predisposition, immunology, endocrinology, nutrition, abnormal trophoblastic invasion, coagulation abnormalities, vascular endothelial damage, cardiovascular maladaptation, dietary deficiencies or excess, and infection have been proposed as etiologic factors for preeclampsia/eclampsia. Craici I, Wagner S, Garovic VD. 1996. [5]. [Medline]. Feb 24 2014. Which specialist consultations may be beneficial in the treatment of eclampsia? For the rare patient who continues to have seizure activity while receiving adequate magnesium therapy, seizures may be treated with sodium amobarbital, 250 mg IV over 3-5 minutes. Eclamptic convulsions are life-threatening emergencies and require the proper treatment to decrease maternal morbidity and mortality. Her case should be followed for recognition and treatment of preeclampsia. Hypertens Pregnancy. Phase 1 lasts 15-20 seconds and begins with facial twitching. 1994 Nov 26. The absence of signs or symptoms before seizure include the following: The relation of seizure to delivery is as follows: Although patients with severe preeclampsia are at greater risk for seizures, 25% of patients have symptoms consistent with mild preeclampsia (i.e., preeclampsia without severe features) before the seizures.

This positioning decreases the risk of aspiration and will help to improve uterine blood flow by relieving obstruction of the vena cava by the gravid uterus. Eclampsia can result in central nervous system (CNS) abnormalities such as cerebral overperfusion due to loss of autoregulation, cerebral edema, and cerebral hemorrhage. Ronald M Ramus, MD Professor of Obstetrics and Gynecology, Director, Division of Maternal-Fetal Medicine, Virginia Commonwealth University School of Medicine Showing the wound free of purulent drainage with early signs of healing. [Medline]. When emergent cesarean delivery is indicated, substantiating the absence of coagulopathy before the procedure is important. An IV bolus of hydralazine (5-10 mg over 2 minutes) or labetalol (initial dose 20 mg) is recommended. How is CNS pathology of eclampsia evaluated? What models are used to predict the risk for complications in women with eclampsia? How is maternal pain relief administered during delivery of women with eclampsia? When is labor induced in patients with eclampsia? There exist over 50 years of data and experience using magnesium for this purpose with excellent safety and efficacy. With increasing blood pressure, cerebral autoregulation is impaired resulting in cerebral regions of ischemia as well as microhemorrhage, each of which may initiate a seizure focus. [Medline]. Discussing the risks and educating patients about the possibility of delayed postpartum preeclampsia is important, regardless of whether they develop hypertensive disease prior to discharge. Delayed postpartum preeclampsia and eclampsia: demographics, clinical course, and complications. Seizures usually terminate after the loading dose of magnesium. Long-term Risk of a Seizure Disorder After Eclampsia. What are the central nervous system effects of eclampsia? What are the goals of drug treatment for eclampsia? For recurrent seizures or when magnesium is contraindicated, one may use lorazepam (Ativan; 2-4 mg IV over 2-5 minutes) or diazepam (Valium; 5-10 mg IV slowly) can be used to terminate the seizure. 2011 May 19.

Supportive care for eclamptic convulsions includes the following: Close monitoring (invasive, if clinically indicated). Regional anesthesia is contraindicated in the presence of coagulopathy or severe thrombocytopenia (< 50,000 platelets/µL). [6] HELLP syndrome is a severe form of preeclampsia and involves hemolytic anemia, elevated liver function tests (LFTs), and low platelet count. In developed countries, many reported cases have been classified as unpreventable. Typically, emergent cesarean delivery is not indicated for this postseizure transient bradycardia; it spontaneously resolves. 309(6966):1395-400. [Medline]. [Medline].

What are the cautions for the use of spinal anesthesia in patients with eclampsia? If the patient has preexisting hypertension, she should have good control before conception and throughout her pregnancy. Once the seizure is controlled and the patient has regained consciousness, the patientâs general medical condition should be assessed to identify any other causes for seizures. This compensates for the respiratory and lactic acidosis that develops during the apneic phase. 1995 Jul 27. There is also a fetal manifestation of preeclampsia involving fetal growth restriction, reduced amniotic fluid, and abnormal fetal oxygenation. Cadden KA, Walsh SW. Neutrophils, but not lymphocytes or monocytes, infiltrate maternal systemic vasculature in women with preeclampsia. A study by Vadillo-Ortega et al suggests that in a high-risk population (eg, previous pregnancy complicated by preeclampsia, preeclampsia in a first-degree relative), supplementation during pregnancy with a special food (eg, bars) containing L-arginine and antioxidant vitamins may reduce the risk of preeclampsia. Irrespective of gestational age, a prolonged induction with clinically significant worsening of maternal cardiovascular, hematologic, renal, hepatic, and/or neural status is generally an indication for cesarean delivery when the anticipated delivery time is remote. Cesarean delivery may be necessary for obstetric indications or a deteriorating maternal condition. How are uric acid levels affected by eclampsia? Several autopsy findings support this model and consistently reveal swelling and fibrinoid necrosis of vessel walls. When is cesarean delivery considered in patients with eclampsia? This website also contains material copyrighted by 3rd parties. Seizures in the first trimester or well into the postpartum period probably are due to CNS pathology and warrant full evaluation, including computed tomography (CT) scanning of the head, lumbar puncture (if clinical evidence of meningitis or concern for hemorrhage exists), determination of electrolyte levels, and urine or serum toxicologic screening.

Uric acid levels may be mildly to markedly increased. [22] Alternatively, lorazepam or diazepam may be administered (as described above) for status epilepticus. Obstet Gynecol. [2] Imbalanced prostanoid production and increased plasma antiphospholipids have also been implicated in eclampsia. General anesthesia in women with eclampsia increases the risk of aspiration, and airway edema may make intubation difficult.

When initially evaluating a patient with eclampsia, become familiar with the level of care that the medical center can offer the patient, as eclampsia clearly poses a risk of considerable maternal and neonatal morbidity and mortality. Obstet Gynecol. (They also performed more poorly on the Hospital Anxiety and Depression Scale.) 208(6):468.e1-6. What is the role of magnesium sulfate in the treatment of eclampsia? It is believed that in eclampsia there is abnormal cerebral blood flow in the setting of extreme hypertension. However, they scored similarly to the control subjects with regard to attention, executive functioning, visual perception, and working and long-term memory. DIC is rare, unless there is an associated abruption. [Medline]. 2009 Feb. 104(2):90-4. [Full Text]. The maternal mortality rate is as high as 14% in developing countries. Care must be taken not to decrease the BP too drastically; an excessive decrease can cause inadequate uteroplacental perfusion and fetal compromise. [Medline]. Vigil-De Gracia P. Maternal deaths due to eclampsia and HELLP syndrome. Pulmonary capillary wedge pressure (PCWP) may vary from low to elevated. How is preeclampsia differentiated from eclampsia? Preeclampsia can quickly develop into eclampsia. [2] However, whether this is due to the antiphospholipids themselves or to some other underlying process is not clear.

Studies have shown that low-dose aspirin in women at high risk for preeclampsia can contribute to a decreased risk of preeclampsia, a reduction in preterm delivery rates, and a reduction in fetal death rates, without increasing the risk of placental abruption. Preeclampsia and future cardiovascular risk: formal risk factor or failed stress test?. Obstet Gynecol. If the fetal heart tracing does not improve following a seizure, further evaluation should be undertaken. It also can produce significant increases in systemic and cerebral pressures during intubation and extubation.

The interval from the onset of the seizure to the fall in the fetal heart rate is typically 5 minutes or less. The natural progression of the disease is from symptomatic severe preeclampsia (differentiated from preeclampsia by specific vital signs, symptoms, and laboratory abnormalities) to seizures. [1] : Cell adhesion molecules (ie, P-selectin, vascular endothelial adhesion molecule-1 [VCAM-1], Intercellular adhesion molecule-1 [ICAM-1]), In addition, it is believed that antiangiogenic factors, such as placental protein fms-like tyrosine kinase 1 (sFlt-1) and activin A, antagonize vascular endothelial growth factor (VEGF). 30(3 Suppl 1):S16-23.
