In 521 pregnancies complicated by hypertensive disorders (PHD) and in 200 control cases, we studied the incidence of intrauterine growth retardation (IUGR), depression in the newborns, general morbidity of live newborns requiring admission and perinatal mortality. We also analyzed the relationship between these conditions and the type and severity of hypertension, gestational age, presence of symptoms of the classic EPH triad and of abnormal uric acid values, hemoconcentration, and low urinary estriol values. Perinatal mortality (especially antepartum) was significantly increased in severe pre-eclampsia, chronic hypertension and chronic hypertension with superimposed pregnancy-induced hypertension (PIH); in all the cases with PHD it was three times higher than that of the control group (59% versus 20% and five times higher than the global perinatal mortality of the 25,763 deliveries attended during the same period (12% General morbidity reached 44% in severe pre-eclampsia and 75% in antepartum eclampsia. But the preterminal deliveries were also more frequent in PHD, especially in severe pre-eclampsia-eclampsia. Nevertheless, the perinatal morbidity and mortality in general increased when proteinuria and edema plus proteinuria were associated with hypertension, and the incidence was significantly higher when proteinuria surpassed 100 mg/dl. Morbimortality also increased in the presence of hemoconcentration, hyperuricemia, and low estrioluria.

In a community based study, 110 children with febrile convulsions (FC) were identified prospectively. Pre- and perinatal risk factors were compared with 213 age and sex matched controls sampled from the community. During pregnancy, proteinuria and preeclampsia/eclampsia occurred more often in mothers of cases. Premature birth and bilirubinemia greater than 200 mumol/l were also more common in cases. There were no differences between cases and controls in occurrence of chronic illnesses in mothers, parents age at birth, birth order, and factors occurring during delivery such as type of anesthesia, occurrence of acute or elective cesarean section, use of vacuum extraction, mode of presentation, signs of fetal distress in amnion fluid, umbilical problems, abnormalities of fetal heart rate or duration of delivery. Perinatal asphyxia was uncommon and there was no difference between cases and referents. Occurrence of complications during the first neonatal week did not differ between groups.

The preeclampsia-eclampsia syndrome is a severe complication of the third trimester of pregnancy and represents the first cause of maternal death. It is mainly characterized by: weight increase, proteinuria and hypertension and can evolve with convulsions and maternal death. The etiology still remains unknown although a series of events have been identified, starting with endothelial damage and local vasoconstriction leading to hypertension. These events occur at first locally in the placental district and become generalized. This paper reports experimental and clinical data in order to demonstrate: 1) the presence of a substance that could evoke experimentally the damage present in this syndrome, 2) a mechanism that delivers such a substance to its primary action site, the placenta, and 3) the possibility to inhibit either the substance or the delivery mechanism in order to prevent this disease. Serotonin appears to play an important role in the chain of events leading to preeclampsia. Certain histological aspects, present in pregnant women with this type of hypertension, have been observed in experimental animals after the administration of serotonin. Platelet derived serotonin could be sufficient, in the case of endothelial damage, to determine vasospasm. In a condition of hypercoagulability, such as pregnancy, this situation can trigger a chain of mechanisms ending with renal damage. Low dose aspirin seems a valid therapeutic approach reducing thromboxane concentrations and therefore preventing vasospasm. In this way the pathogenetic sequence culminating in the preeclampsia-eclampsia syndrome is interrupted. Ketanserin inhibits the hypertensive potential of serotonin by selectively acting on S2 serotonin receptors and appears to be an effective treatment in this type of pregnancy induced hypertension.

A case of amphetamine abuse in late pregnancy is reported. The presenting features of convulsions, confusion, agitation with hypertension and proteinuria led to a diagnosis of eclampsia for which a caesarean section was performed. Investigations and differential diagnosis of convulsions in late pregnancy are reviewed. A general urinary drug screen gives results after 24 hr whereas, if amphetamine abuse is suspected, this can be confirmed within three hr if a specific test for urinary amphetamines is performed. The sympathomimetic effects of a single dose of amphetamine are contrasted with the depression of the sympathetic nervous system which occurs after long-term use. Implications for anaesthesia are discussed.

We report the case of a 32-year-old multipara who presented preeclampsia on the fourth day after childbirth without receiving proper treatment that progressed to eclampsia 4 days later. Pregnancy and delivery had been uneventful. The patient presented proteinuria (30 mg/dl), serum total proteins 5.3 g/dl and serum albumin 3.3 g/dl. Blood pressure was controlled with methyldopa, 500 mg at six-hour intervals by intravenous route. The patient presented hypoxemia secondary to bilateral pleural effusion and aspirative pneumonia requiring mechanical ventilation and invasive hemodynamic monitoring. Treatment with cefotaxime, 1 g at six-hour intervals by intravenous route and clindamycin, 600 mg at six-hour intervals by intravenous route was initiated. Sedation was maintained with thiopental sodium, 3 mg/kg/hour in continuous infusion. At dismission, the patient was completely recovered from her clinical picture and needed no antihypertensive therapy. Physiopathologic features and the aforementioned complications are discussed with particular reference to differential diagnosis.

During a 12-year period, 254 cases of eclampsia were managed at this center. Eighty patients (32%) did not have edema, 58 (23%) had "relative hypertension," and 49 (19%) did not have proteinuria at the time of convulsions. Eclampsia developed at less than or equal to 20 weeks in 6 patients and beyond 48 hours post partum in 40 (16%). Convulsions developed in 33 while they were receiving standard doses of magnesium sulfate for preeclampsia during or after birth, and subsequent seizures developed in 36 (14%) after magnesium sulfate therapy was started. There was one maternal death (0.4%) and morbidity was frequent (acute renal failure, 4.7%; pulmonary edema, 4.3%; cardiorespiratory arrest, 3.1%; and aspiration, 2%. The use of multiple drug therapy was associated with significant maternal and neonatal complications. The total perinatal mortality was 11.8%, with the majority of them related to either abruptio placentae or extreme prematurity. These findings emphasize the need for intensive monitoring of women with preeclampsia throughout hospitalization and underscore the importance of maternal stabilization before and during transfer.

Dextran 40 was used in the management of hypovolemia and hemoconcentration in patients with hypertensive disease induced by pregnancy; 50 cases were randomly selected from a total of 150 patients from the Intensive Care Unit for Adults. The obstetrical profile, and perinatal profile, were determined. Hemodynamic and laboratory parameter, were statistically analyzed, before administration of Dextran 40 and at 2, 4, 6 and 8 hours after, and were compared. Eighty eight per cent of the selected cases corresponded to severe pre-eclampsia, and 12% to eclampsia; the age of the patients was 24 years; the number of gestations was 2.1 and they were at 32.6 weeks of gestation, average; eighty four percent were pregnant, and 16% were in puerperium at the moment of starting infusion; ninety per cent of the patients underwent cesarean section, and 10% were attended of a delivery. The products weighed 2,696 g; Apgar of 7.1 and 8.4 at fetal one and five minutes respectively, in average; there was one fetal death (2.4%), and one mortinate (2.4%); morbidity was 12%, and 85% of the products evolutionated satisfactorily. There were no maternal deaths. There was an statistically significant decrease is of BP after two hours, and a decrease of heart beat after four hours from starting infusion; as well as an increase in central venous pressure and diuresis, both after two hours from starting infusion of Dextran 40. There was a quantitative diminution of edema and proteinuria; as well as a quantitative diminution of hemoglobin, hematocrit, and fibrinogen after eight hours from starting infusion.(ABSTRACT TRUNCATED AT 250 WORDS)

A prospective study conducted between January, 1985 and September, 1987 involved 60 pregnant women who had previously suffered from hypertension in pregnancy with or without foetal and maternal complications. Thirty women received aspirin 250 mg every other day and dipyridamole 300 mg per day, starting from the 3rd month of pregnancy (group I); 30 women were examined regularly from the onset of pregnancy and received the conventional symptomatic treatment of complications that occurred (group II). Women in these two groups were similar in age, parity and previous obstetrical complications. Twenty-five women of group I had a perfectly normal pregnancy, as against 5 women of group II (P less than 0.001). Hypertension and/or proteinuria were observed in 5 women of group I and 15 of group II (NS). The 13 severe complications recorded (foetal death, eclampsia, retroplacental haematoma) occurred exclusively in women of group II. The duration of pregnancy and weight of the newborn were significantly greater in group I than in group II. Thus, antiplatelets appear to have an uncertain preventive effect on hypertension of pregnancy and a much more obvious prophylactic effect on major foetal and maternal complications.

The outcome is described for 106 patients with severe hypertension in pregnancy requiring delivery between 26 and 34 weeks. Management was with methyldopa, hydralazine when required and delivery by caesarean section when indicated. Most patients were delivered for cardiotocographic fetal distress or unstable maternal blood pressure. Eighty-five babies (80%) survived and were well at follow-up at 1 year; the perinatal mortality was 123/1000 total births. One patient had postpartum eclampsia, one had pulmonary oedema and one had transient renal failure, but all mothers left hospital well. Stepwise logistic regression analysis showed that the primary positive factor for survival of a healthy baby was gestational age, which was strongly correlated with birthweight. The need for caesarean section as an emergency, hypotension after parenteral hydralazine, intrauterine growth retardation, and severe proteinuria were adverse factors. Intraventricular haemorrhage had a major adverse effect on neonatal survival; it was predisposed to by prolonged maternal hypertension and by low gestational age.

EPH-gestosis (pre-eclampsia-eclampsia) characterized by edema, proteinuria and hypertension occurs primarily in the nullipara, usually after the 20th gestational week. As in normal pregnancy there is striking change in both renal blood flow and glomerular filtration rate a slight increase in urinary protein secretion is not considered abnormal until it exceeds 300 mg/day. Abnormal proteinuria commonly accompanies pre-eclampsia and may be minimal, moderate or severe (even exceeding greater than 25 g/l). Proteinuria was typed mainly of nonselective glomerular origin by using the SDS-disc-electrophoresis. Additionally the clearance ratio of IgG to transferrin in all patients with abnormal proteinuria was evaluated. In none of the patients studied the ratio was less than 0.1 (highly selective). As severe proteinuria is associated with fetal growth retardation, preterm deliveries and prenatal mortality the quantitation and typing of early proteinuria is essential for considering patients who are at risk for developing EPH-gestosis.
