This is a randomized controlled trial to estimate the efficacy of low dose aspirin for preventing preeclampsia in women identified as high risk. The investigators hypothesize that the risk of preeclampsia in women identified by a first trimester multiparameter predictive model to be at high risk will be significantly reduced by initiating low dose aspirin early in pregnancy.
The investigators examined whether there was a difference in the occurrence of ST depressions after injection of five or ten units of oxytocin, in preeclamptic patients delivered by caesarean section (CS) under regional anesthesia.
This study will compare blood vessel and hormone differences between women who have a history of a pregnancy complicated by preeclampsia or high blood pressure, and women who have a history of uncomplicated pregnancy in the last 10 years. The investigators hypothesize that postpartum women with history of preeclampsia will have altered blood vessel function and abnormal hormone levels compared with postpartum women with history of uncomplicated pregnancy. This study will take place over the course of 2 weeks. Each subject will be assessed on a fixed low-salt diet and a fixed high-salt diet. Subjects will have 2 non-invasive blood vessel imaging tests and fasting blood draws.
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.
This is a non-inferiority, prospective study of the relationship between the 24-hour urine protein collection and spot protein:creatinine ratio in the diagnosis of preeclampsia involving a sample of 18-45 year-old pregnant women attending the new Obstetrics orientation. The investigators will follow all participants who consent to be part of this study throughout their entire pregnancy. Those who get evaluated for preeclampsia will then have a P:C ratio anytime their Primary Obstetrics provider orders a standard of care 24-hour urine collection (standard of care). Those participants who are not evaluated for preeclampsia during their pregnancy will be dropped from the study. Participants evaluated for preeclampsia during the prenatal period will be asked to provide a random spot clean-catch urine sample at intervals of approximately 0 and 24 hours following the initiation of the 24-hour urine collection. The patient's demographic and clinical data, as well as the spot protein:creatinine ratio and 24-hour urine protein will be collected and analyzed at the conclusion of the study period.
The purpose of this study is to investigate the acute and chronic effect of consumption of flavanol-rich chocolate on endothelium function in pregnant women at high risk for preeclampsia.
Preeclampsia is a syndrome that occurs in approximately 3% to 8% of pregnancies and is associated with considerable maternal and neonatal morbidity and mortality. Except for termination of the pregnancy, effective treatments/preventative measures for preeclampsia are lacking. Although prolongation of pregnancy benefits the fetus, it is detrimental to the mother, and is associated with hypertension, proteinuria, and symptoms that suggest kidney, brain, liver and cardiovascular system involvement. Placental soluble fms-like tyrosine kinase 1 (sFlt-1) is elevated in women with preeclampsia, with levels that fall after delivery. sFlt-1 is a variant of the vascular endothelial growth factor (VEGF) receptor Flt-1, and in the circulation, acts as a potent VEGF and placental growth factor (PlGF) antagonist. Given that sFlt-1 levels are elevated in preeclampsia, we are investigating if removal of sFlt-1 from the plasma of women with preeclampsia can improve maternal and fetal outcomes. Short-term extracorporeal apheresis with the LIPOSORBER LA-15 System will be the primary intervention using methods that have been previously applied in pregnant women with familial hypercholesterolemia.
This is a Multicenter, randomized, open‐label, parallel groups study to test the hypothesis that prophylactic low molecular weight heparin (LMWH) (enoxaparin) initiated before 14 weeks of gestation could improve maternal and perinatal outcome in women at high risk for developing placental‐mediated pregnancy complications.
The purpose of this study is to assess the predictive role of serum inflammatory markers in pregnant women who subsequently develop preeclampsia.
