When you have preeclampsia, your blood pressure is elevated (higher than 140/90 mmHg), and you may have high levels of Some practitioners withhold magnesium sulfate if BP is stable and/or mildly elevated and if the laboratory values for LFTs and platelets are mildly abnormal and/or stable. WebPreeclampsia is a condition marked by high blood pressure in pregnant women. Intensive monitoring in women who are at increased risk for developing preeclampsia, when identified by a predictive test, may lower the incidence of adverse outcome for the mother and the neonate. Increased uric acid is a marker of sodium reabsorption which occurs due to reduced renal blood flow and Angiotensin II. These clinical studies, however, do not delineate whether preeclampsia is a cause or a marker for longterm vascular disease. Although randomized trials in women with gestational hypertension and preeclampsia demonstrate the safety of outpatient management with frequent maternal and fetal evaluations, most of the patients in these studies had mild gestational hypertension. The use of lowmolecular weight heparin in women with thrombophilia who have a history of adverse outcome has been investigated. What is the role of hypertension in the pathogenesis of preeclampsia?

Risk factors for preeclampsia are as follows BJOG. A history of gestational hypertension or preeclampsia should strongly raise clinical suspicion. HELLP syndrome (hemolysis, elevated liver enzymes, low platelet count) may complicate severe preeclampsia. Early onset pre-eclampsia arises owing to defective placentation, whilst late onset pre-eclampsia may center around interactions between normal senescence of the placenta and a maternal genetic predisposition to cardiovascular and metabolic disease. The causes, placental and maternal, vary among individuals. Why should fluid input be carefully measured in preeclampsia? Other physicians feel that even patients with gestational hypertension should receive magnesium, as a small percentage of these patients may either have preeclampsia or may develop it.
