Hypertension Of Preeclampsia

Preeclampsia is a pregnancy complication characterized by the development of hypertension and proteinuria in the second half of pregnancy. There is currently no definitive cause, however, it is thought to result from disturbed development of the placenta, leading to endothelial dysfunction and systemic inflammation. Syncytiotrophoblast extracellular vesicles (STBEVs) are produced when the syncytial placental surface is shed into the maternal circulation. We hypothesized that this would cause vascular endothelial cell dysfunction via activation of the multi-ligand lectin-like oxidized low-density lipoprotein scavenger receptor (LOX-1). This could then initiate a cascade of events. One of the effects of LOX-1 activation is the production of reactive

During pregnancy women experience an increased appetite and cravings, or distaste of other food types (Niebyl, 2010). It is theorised that NV in pregnancy occurs due to evolutionary change, it’s advantageous to pregnant women by avoiding food which may contain microorganisms or unsafe toxins. The relationship between hCG and NVP are linked into protection of the vital development and formation of the embryo in the early to second trimester of pregnancy by avoiding potentially harmful foods (Lee & Saha, 2011).

(2) Therefore, for medics to effectively manage the eclamptic patient, they should understand key signals and, ideally, the patient’s past medical history. Based on data analysis of patients considered to be “at risk” for developing eclampsia, those with “prior pre-eclampsia, chronic hypertension (HTN), pre-gestational diabetes, assisted reproductive technology, and BMI >30 were most strongly associated with a high rate of pre-eclampsia.” (4) Lastly, women at both extremes of childbearing age (young and old) are more likely to develop pre-eclampsia than other parous women. These are key factors to consider when initially evaluating a patient at greater than 20 weeks gestation with BP of over 140/90. (2)

Preeclampsia, HELLP syndrome and eclampsia are part of a spectrum of hypertensive disorders specific to pregnancy, which are a leading cause of maternal and fetal morbidity worldwide (Lowdermilk, Perry, Cashion, & Alden, 2015). The root cause of preeclampsia is the placenta: in a healthy pregnancy, the muscular components of the uterine spiral arteries are replaced by cytotrophoblastic tissue from the fetus which then erodes the myometrium, causing the arteries to widen and lose their vasoconstrictive properties (Gilbert, 2010). This increases the diameters of the uterine spiral arteries to 4 to 6 times their nonpregnant size, allowing increased blood volume to flow to the placenta. In preeclampsia cytotrophoblastic tissue fails to widen the maternal spiral arteries, and the pressure in the maternal vascular system increases and defective placentation (defined as decreased tissue perfusion in the placenta) occurs. Ischemia in the placenta triggers the release of antiendothelial factors that are toxic to endothelial cells, leading to endothelial cell dysfunction. Because endothelial cells line all the blood vessels, this leads to multiorgan system involvement. Destruction of endothelial cells in the blood vessels causes decreased production of vasodilators such as prostacyclin and nitric oxide. Preeclampsia affects 2 to 7 percent of first time mothers, and is most common in mothers younger than 19 or older than 40 (Lowdermilk, Perry, Cashion, & Alden, 2015).

Pre-eclampsia is a condition that only pregnant women develop. It is when the placenta doesn’t work in the way it should. In the womb, an infant survives because of the placenta. It provides the infant with much needed nutrients and oxygenation. The condition makes the placenta only give nutrients to the brain and heart, and depletes the needed nutrients to the rest of the infant’s organs (First Candle). This results in the infant’s demise. The most common signs that a woman has developed it is high blood pressure and high levels of the electrolyte protein in her urine. In addition to those symptoms, the mother’s hands, feet and legs will exhibit signs of swelling. Pre-eclampsia develops into eclampsia when it is undiagnosed. There is no cure for pre-eclampsia and that is why it is so dangerous. Usually when a woman is diagnosed with the

When a woman is pregnant, any risk to herself or her baby is a significant problem. How many women suffer from Preeclampsia? Out of five to ten women. A woman who had a normal blood pressure before pregnancy can develop high blood pressure and excess proteins in her urine after the first twenty weeks of pregnancy. When this occurs a woman is told she has a disease named preeclampsia, which puts her baby and herself at risk. Preeclampsia grows unexpectedly after twenty weeks, with a high increase in blood pressure, excess proteins in her urine, extreme headaches, nausea, dizziness, sudden weight gain as sudden symptoms as sudden signs of sickness.

Preeclampsia the disease of the first pregnancies. Preeclampsia has several potential adverse outcomes for a pregnant woman and the neonate. Preeclampsia can occur anywhere after the 20th week of pregnancy. Cunningham (2010) described preeclampsia as a continuum of worsening disease. Each case of preeclampsia varies in symptoms and severity depending on the health of the pregnant woman, and usually resolves after delivery within 2-3 weeks. “Healthcare indicators are shown to be useful to assess, monitor, and improve quality of care” (Wollersheim et al., 2007). Recognizing characteristics of preeclampsia can save maternal and fetal lives.

The mother could have preeclampsia and may even die while giving birth. Preeclampsia is a pregnancy complication characterized by high blood pressure and signs of damage to another organ system, usually the kidneys. Preeclampsia usually begins after 20 weeks of pregnancy in a woman whose blood pressure had been normal. Even the slightest rise in her blood pressure may be a sign of preeclampsia. (http://www.mayoclinic.org/diseases-conditions/preeclampsia/basics/definition/con-20031644) Symptoms of preeclampsia include excess protein in the urine, severe headaches, blurred vision, abdominal pain, nausea or vomiting, or shortness of breath. Sudden weight gain and swelling more than a normal pregnancy, typically in the hands and face, often accompanies preeclampsia. (http://www.mayoclinic.org/diseases-conditions/preeclampsia/basics/symptoms/con-20031644) Preeclampsia may be hereditary, but it is not said in stone whether it is or not due to both limited testing and research on the disorder. (http://healthresearchfunding.org/preeclampsia-hereditary/) Her baby may have breathing problems, cerebral palsy, developmental delays, problems with sight, hearing problems, and feeding difficulties.

Preeclampsia is the new onset of hypertension and either proteinuria or end-organ dysfunction after 20 weeks of gestation in a previously normotensive woman. Although most women develop signs of the preeclampsia in late pregnancy with gradual worsening until delivery, a few studies have reported delayed or new-onset postpartum preeclampsia in patients with no antecedent diagnosis of hypertensive disease in the current pregnancy (). Postpartum preeclampsia is defined as the presence of hypertension and proteinuria, occurring up to 4-6 weeks after delivery (yancey, filetti). While the pathophysiology of preeclampsia involves abnormal placental vasculature and altered maternal systemic endothelial function (gilbert, beckmann), postpartum preeclampsia

Preeclampsia is a hypertensive disorder; however, the actual cause of the disease is unknown. Because this condition begins at conception, it is believed that the placenta plays an important role in causing preeclampsia. In women without preeclampsia, the spiral arteries in the placenta remodel to allow sufficient oxygen and blood flow to the fetus. In preeclamptic women, the remodeling of the spiral arteries does not take place, resulting in narrow

This normally appears around 20 weeks of gestation in a pregnancy, and is shown in women who has a history of high blood pressure or family members with a history of it, diabetes, kidney diseases, ovarian cysts, autoimmune disorder, organ transplants, in-vitro fertilization, and multiple gestations (Preeclampsia Foundation, 2013). Also being over the age of 35, being anemic, obesity, and even this being a first pregnancy is all risk factors of preeclampsia (Perry, Hockenberry, Lowdermilk, & Wilson, 2010).

Mrs. Livingston needs to maintain a systolic blood pressure less than 150 mmHg, and a diastolic pressure less than 100 mmHg to prevent the risk of preeclampsia during pregnancy (Carson & Chen, 2014, p.129). For this reason, labetalol and methyldopa are the first-line drugs for pregnant women with hypertension (Carson & Chem, 2014, p. 130). For Mrs. Livingston, labetalol will replace lisinopril to control her blood pressure. Furthermore, she will tolerate labetalol better than methyldopa because of the latter’s side effects of fatigue and drug-induced lupus

The risk factors of gestational hypertension developed into preeclampsia are having past history of preeclampsia, first pregnancy, a family history of preeclampsia and some preexisting medical conditions1. Preexisting medical conditions like diabetes that related to renal or vascular disease which lead to high blood pressure and chronic kidney disease (CKD) which causes low glomerular filtration rate and subsequently lead to hypertension may develop preeclampsia. Moreover, pregnant women with twin pregnancies and maternal age may also contribute to preeclampsia3.
