To study the effect of lignocaine nebulization on attenuation of the pressor response during induction and emergence of anesthesia in patients with severe pre-eclampsia
Preeclampsia is a significant medical condition occurring in 3-8% of pregnancies and impacts deleteriously both maternal and fetal health. An important discovery has been made by Dr Craig D Scoville showing that early Tdap vaccinations in pregnancy can reduce the incidence of preeclampsia by more than 50%. A prospective clinical research trial is proposed and urgently needed to validate this finding and thereby make a significant contribution in reducing the incidence of this common and severe complication of pregnancy.
This study aims to evaluate the feasibility of implementing a clinical model for precision screening of early pre-eclampsia into the current prenatal screening service at Sunnybrook Health Sciences Center (SHSC).
To determine if low dose aspirin reduces the incidence of hypertensive disorders of pregnancy (gestational hypertension, preeclampsia, eclampsia, and HELLP syndrome) in pregnant women with stage 1 hypertension and elevated blood pressure.
This is a randomized double blind placebo controlled trial comparing Nifedipine 30mg XL to placebo in 110 patients after decision has been made to proceed with induction of labor for the diagnosis of preeclampsia with severe features.
Introduction: The placenta is the organ that permits the maternal-fetal exchange of the oxygen and nutrients. The development of its vascular network occurs in the first trimester. Any deficit during this important angiogenesis procedure can lead to the dysfunction of the placental vasculature, which can potentially cause pathologies including preeclampsia (PE) and intrauterine growth restriction (IUGR). PE concerns 3% of the pregnancy in France. It can occur at any gestational age and leads to serious complications such as eclampsia, the HELLP syndrome or the retro-placental hematoma. IUGR does not only lead to the morbidity and fetal and neonatal mortality, but also has a predisposition for certain pathologies in the adulthood. Many groups have studied the placenta vasculature at the microscopic (histological) scale. However, recent studies show that in addition to the damage at the microvasculature level, the macroscopic placental vessel architecture is also altered. Nonetheless, the origin and the etiology of this phenomenon remains unknown. Since it is difficult to apply in-vivo imaging techniques on pregnant women due to the restriction of usage of contrast agent. Alternatively, ex-vivo MR angiography (MRA) techniques have been developed by our team and others to visualize the entire placental vasculature in a faster way (as compared to corrosion casting). Up to now, only the study of the healthy placenta is done and published. The analysis of the pathological placental vasculature (i.e. PE and IUGR cases) at different gestational age and its comparison to the physiological ones have not been conducted, which will potentially enable a better understanding of the placental vasculature pathology. Objectives: the main objective of this study is to compare the vasculature architecture of the normal and pathological placentas (with possible alteration in the placental vasculature). Methods and analysis: This is a monocentric, prospective, controlled but not randomized study. The investigators expect to include 110 women in Nancy. The pregnant women will be recruited when they arrived at the maternity hospital for delivery, for both the physiological and potential pathological cases. The notice of this study will be given. If no opposition is given by the subject, the placenta may be collected. This study will not collect the patient consent but only the opposition declaration will be collected.
Introduction: Vanadium important pollutants produced from anthropogenic activities, has been suggested to be embryotoxic and fetotoxic in a lot of studies. Magnesium sulfate therapy is used very common to prevent seizures in women with preeclampsia. However, the causes of preeclampsia are little known and heavy metals merit further investigation. The investigators will be tested whether late - onset preeclampsia (LOPE) was associated with exposure to these metals. Methods: This study was designed to determine maternal plasma/urine/hair magnesium and vanadium concentrations in women with LOPE (n=70) compared to those of normotensive pregnant women (n=70) and to those of normotensive-healthy non-pregnant women (n=70). These metals concentrations will be measured using inductively coupled plasma-mass spectrometry were compared.
Background: Preeclampsia is one of the leading causes of maternal and perinatal morbidity and mortality worldwide, and it affects 3% to 8% of all pregnancies. Maternal and perinatal morbidity and mortality resulting from preeclampsia are due to its complications. Clinical prediction of complications associated with preeclampsia may facilitate initiation of timely management to reduce or avert adverse outcomes associated with the condition. Studies on current biomarkers (proteinuria or uric acid) have shown poor performance in the prediction of adverse pregnancy outcomes in preeclamptic women. Placental growth factor (PlGF) is an angiogenic growth factor that is exclusively produced by the trophoblast. Circulating levels of placental growth factor have been reported to be reduced in women with preeclampsia. Therefore there is a need to evaluate the predictive performance on adverse pregnancy outcomes of this pregnancy specific biomaker among preeclamptic women. Aim: To determine the predictive accuracy of maternal serum PlGF level for adverse pregnancy outcomes in preeclamptic women. Materials and Method: It is a prospective cohort study that will be conducted on 110 women that will be admitted for preeclampsia in the Federal Teaching Hospital and Saint Patrick Mile 4 Hospital Abakaliki. On admission women who will give informed consent will have their blood sample collected. The sample will be analysed using Enzyme linked Immunosorbent Assay technique to determine the level of PlGF (pg/ml). All the study participants will be followed up until delivery. The socio-demographic characteristics and maternal and perinatal adverse outcomes will be entered into a proforma. Data will be entered and analyzed using SPSS version 22.0. Strength and limitation: The strength of the study is that a single biomaker, PlGF, will be assayed and the test will be performed once, which is cost-saving. The limitation of this study is that there would not be long term follow up of participants after hospital discharge and so complications that will occur after discharge will not be assessed. Conclusion: Considering the contribution of preeclampsia to maternal morbidity and mortality in Abakaliki and poor predictive performance of available biochemical markers on adverse pregnancy outcomes among preeclamptic women, there is need to conduct this study so as to ascertain the utility of PlGF in predicting adverse outcome among preeclamptic women in Abakaliki.
Preeclampsia is a multifocal syndrome reported in 2-8 % of pregnancies. It is diagnosed in the second half of pregnancy by two separate measurements of systolic blood pressure ≥140 mmHg and/or a diastolic blood pressure ≥ 90 mmHg in the same arm and proteinuria >300 mg in 24 h urine collection. The risk for serious complications such as pulmonary edema, cerebrovascular accidents, coagulopathy, and hemorrhage is 10 to 30 fold higher among parturients with severe preeclampsia. Severe preeclampsia is defined by one or more of the following clinical features: severe hypertension (systolic arterial pressure 160 mmHg and/or diastolic arterial pressure 110 mmHg on more than one occasion at least 4 h apart while the patient is on bed rest, renal dysfunction (serum creatinine >1.1mg/dl or doubling of serum creatinine in the absence of another renal disease, platelet count less than <100,000 mm3, acute pulmonary edema, epigastric pain not responding to medical treatment, new-onset cerebral and visual manifestation, hemolysis, elevated liver enzymes and low platelet count syndrome (HELLP syndrome)
