Eclampsia is the most serious manifestation of a toxaemic encephalopathy which may also have nonconvulsive manifestations, such as headache, visual disorders or retinal or cortical origin, confusion or disturbances of consciousness. Some authors consider eclampsia as being only one particular aspect of hypertensive encephalopathy. However, recent studies have drawn attention to the importance of angiospasm which might not be a pure reaction to hypertension but might result from a relative deficiency in vascular prostacyclin. These physiopathological factors, to which must sometimes be added disseminated intravascular coagulation, account for computerized tomographic and neuropathological findings showing cerebral oedema and, in complicated cases, ischaemic or haemorrhagic lesions. Medical treatment must rapidly control the convulsive attacks as well as the arterial hypertension. Magnesium sulfate is not much used outside the United States where it is now strongly controverted. The obstetrical management depends on the time when eclampsia occurs and on the efficacy of the medical treatment.

From the pre-natal follow-up it was remarkable that cases have been admitted relatively late. Hints to a possible development of preeclampsia could be seen from patients history or the routine check up, for example the registration of edema, fetal growth retardation and oligohydramnios. For early diagnosis of preeclampsia we recommend: Calculation of mean arterial blood pressure or its non-invasive measurement; determination of hematocrit, uric acid and total plasma protein (in particular hemorheologic measurements). Hypomagnesemia in preeclampsia, as described by some authors, was also seen in our cases. The complex symptomatology of preeclampsia could be attributed to a generalised disturbance of microcirculation, which leads to definite reactions of the organs concerned. The microcirculatory failure is caused by vasoconstriction, hemoconcentration, hyperviscosity and hypercoagulation (up to DIC and consumption coagulopathy). The resulting symptoms and syndromes can be: EPH, HELLP, hemolytic-uremic Syndrome, hepato-renal Syndrome, thrombocyte and antithrombin III deficiency etc. The drug of choice for treatment of preeclampsia is magnesium sulfate. Its application is based on long-term clinical experience and new aspects on the physiologic and pharmacologic role of magnesium. The recommendations of the German High Blood Pressure League to use calcium antagonists as a basis in the treatment of high blood pressure can be fulfilled particularly in pregnancy by the physiologic calcium antagonist Mg++. Magnesium sulfate should be given in a dosage of 24-72 g daily. The dose should also be made dependent from urinary output. Further treatment patterns of preeclampsia should be adjusted according to each case. The present results also support our hypothesis that magnesium deficiency (besides predisposing factors) could be responsible for the development of preeclampsia (present model shown in detail). Consequently, the early and long-term substitution of magnesium in pregnancy could help reduce preeclampsia.
