Filter by:This case-control study aims to investigate the association between B vitamins and gestational hypertension or preeclampsia.
There may be a role for Lisinopril in improving renal protection in post-partum women who had preeclampsia during pregnancy. The aim of this study is to determine whether routine initiation of Lisinopril after delivery, in women who had preeclampsia while they were pregnant, can control high blood pressure and improve kidney function.
According to U.S. Pharmacist® "low-dose aspirin refers to dosages between 81 mg and 325 mg taken every day to prevent heart attacks, strokes, and colon cancer." It has been found through research that low-dose aspirin also decreases the risk of preeclampsia. The American College of Obstetrics and Gynecologists (ACOG) recommends low-dose aspirin (81mg/day) for women at high risk of preeclampsia. However, some researchers report that a dose of aspirin < 100 mg/day does not seem to decrease the risk of preeclampsia. Another trial studying patients who are at a high risk for preterm preeclampsia, reported a reduction in the occurrence of preeclampsia among patients taking aspirin at a dose of 150 mg. The purpose of this pragmatic randomized study is to compare the difference in the effectiveness of two doses of aspirin: 81 mg versus 162 mg in the prevention of preeclampsia in pregnant women who are at a moderate to high risk for developing preeclampsia.
To determine if the use of impedance cardiography can identify appropriate medications for use in treating chronic hypertensive patients to decrease the risk of preeclampsia.
The purpose of this study is to verify if postprandial walks are effective in obese pregnant women, as regards to gestational weight gain and typical diseases of that period, as gestational diabetes and preeclampsia. Perinatal outcomes will be observed, such as macrosomia, shoulder dystocia and fetal death.
Anesthesia for cesarean section has been a great challenge for the anesthesiologist, for mother and fetus are closely related. So the challenge is to anesthetize the mother without interfering with the physiology of the fetus. The spinal block, although safe, are not free of complications if not treated properly, may be responsible for increased fetal morbidity. Among the major side effects, there is hypotension, with potentially serious consequences for the maternal-fetal dyad. Hypotension in pregnant women at low risk may not lead to major damage, but a pregnant woman with low reserves, as is the case of pregnant women with pre-eclampsia, any drop in blood pressure of the mother can bring harm to the welfare of mother and fetus. Based on the above, the purpose of this study is to compare the effects of maternal and perinatal treatment of hypotension with ephedrine or metaraminol in pregnant women with severe preeclampsia undergoing cesarean section under spinal anesthesia. There will be a randomized, double-blind, which will be included pregnant women with severe preeclampsia with indication of cesarean section, gestational age above 34 weeks gestation and only.Will be Excluded women with hemorrhagic syndromes of pregnancy, HELLP syndrome, eclampsia, cardiovascular or cerebrovascular disease, fetal distress and absolute contraindications to spinal anesthesia. All patients are fully informed of the research objectives and will only be included in the study if they agree to participate and sign the Instrument of Consent. The project was designed following the recommendations of Resolution 196/96 of the National Health and the Declaration of Helsinki for research involving human subjects (2000). In addition, the project was submitted to the Ethics Committee in Research of the Institute of Integrative Medicine Professor Fernando Figueira, is approved. The study will be conducted from June 2011 to July 2012. The study variables are: consumption of metaraminol and ephedrine before and after birth, the occurrence of nausea and vomiting, incidence of maternal hypotension, the occurrence of reactive hypertension, occurrence of bradycardia, pH of umbilical cord, Apgar score 5 minutes, need for face mask ventilation and ICU admission.
The involvement of eukaryotic translation initiation factor 4E (eIF4E) in human placental implantation and in the pathological pregnancies: preeclampsia and IUGR.
Severe preeclampsia often presents with uncontrolled hypertension and therefore requires close monitoring of blood pressure and cardiac performance. The purpose of the study is to compare two methods of measuring the performance of the heart in pregnant women: one by ultrasound of the heart, the other by assessing the pulse generated in the blood vessel of the wrist. We hope that the method using pulse analysis will be as effective as ultrasound, which is labour intensive and operator dependant.
Preeclampsia is a hypertensive disorder of pregnancy and a leading cause of fetal and maternal morbidity and mortality. Recent findings indicate preeclampsia is an inflammatory disorder associated with increased expression of COX-2. This study will test the hypothesis that treatment of women with a COX-2 inhibitor, celecoxib, will stop the inflammatory process and reverse symptoms of preeclampsia.
Eclampsia is a major cause of perinatal morbidity and mortality. The pathophysiology is not known but magnetic resonance imaging (MRI) and Doppler data suggest that overperfusion of the cerebral tissues is a major etiologic factor. Hypertensive encephalopathy from overperfusion, and vascular damage from excessive arterial pressure (cerebral barotrauma) are believed to lead to vasogenic and cytotoxic cerebral edema, with resultant neuronal anomalies, seizure activity and cerebral bleeding if left unchecked. Doppler data have shown that cerebral perfusion pressure (CPP) is abnormally increased in severe preeclampsia and that autoregulation of the middle cerebral artery is affected by this condition leading to increased CPP. Magnesium sulfate (MgSO4) is the most widely accepted eclampsia treatment and prophylactic agent, and it has been used in the USA since the 1950's. Despite widespread use, its mechanism of action is unknown. MgSO4 is given intravenously or intramuscularly and requires specialized nursing training and monitoring to minimize toxicity from respiratory and cardiac depression. Labetalol, a combined alpha and beta blocker, has been used for many years to safely treat hypertension in preeclamptic women, and is now known to reduce CPP in women with preeclampsia. In the United Kingdom labetalol was for many years used as the sole agent in treating preeclampsia, and the rate of seizure was no different to that reported in the USA with MgSO4. Since labetalol can be administered orally, is economical, has low toxicity potential, does not require specialized training to administer or monitor, and decreases CPP, it may be an ideal agent for controlling blood pressure (BP) and decreasing the incidence of eclampsia in women with preeclampsia. The current study is a multicenter, randomized, controlled trial to compare the anti-seizure effect of parenteral MgSO4 versus oral labetalol in hypertensive pregnant women who are eligible for MgSO4 therapy. The primary outcome measure is eclampsia, and the secondary outcome measures include blood pressure control, and relevant antenatal, intrapartum, and postnatal maternal and fetal/neonatal parameters including adverse effects and complications. Inclusion criteria are deliberately broad in order to make the study clinically relevant. Hypertensive pregnant women, in whom the decision for delivery has been made, will be enrolled after written, informed consent. Patients will be randomized to receive MgSO4 therapy as given in their institution, versus oral labetalol (200mg/q6 hours), from enrollment in the study until 24 hours post delivery. There will be 4000 patients in each arm of the study and analysis will be by intention-to-treat. The study is powered to show both therapeutic superiority as well as clinical equivalence. This study has the potential to change the way preeclampsia is managed, and will represent a major advance in terms of the availability and safety of prophylactic therapy, especially in developing nations where MgSO4 is underutilized due to cost constraints.
