Filter by:This study intends to adopt the method of multi-center prospective randomized controlled study. The aim of this study is to obtain localized excision values through a preeclampsia screening model established in early pregnancy, and to evaluate the efficacy of low-dose aspirin intervention for preeclampsia prevention in pregnant women at high risk of screening.
The purpose of this study is to investigate the suitable infusion dose of phenylephrine for prophylaxis against postspinal anesthesia hypotension in parturients with preeclampsia undergoing cesarean section.
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.
Recent sutdies indicate that the existence of corpus lutein in the ovary is a key point to prevent preeclampsia, and patients undergoing FET with hormone replaced cycle have no corpus lutein and the absence of corpus lutein significantly increases the risk of preeclampsia in these patients. We aim to conduct a single center randomized trial study to compare the preeclampsia rate between the natural cycle and the hormone replaced cycle in patients undergoing FET.
The primary outcome will be the effect of rosuvastatin on the resolution of biochemical features associated with severe PE (↑CRP and IL6). .
1. To measure the level of expression of MXRA5 and ANXA4 genes in preeclampsia (PE). 2. To detect the effect of heavy metals (lead (Pb) and arsenic (AR)) on these two genes in the pathology of PE. 3. To explore the association of the previous two genes with the heavy metals in link with Phosphoinositide 3-kinases/Protein Kinase B (PI3K/AKT) pathway. 4. To detect Syndecan-1 by immunohistochemical antibodies. 5. To define the role of extracellular matrix remodelling in PE.
Neuraxial anesthesia has been associated with delayed brainstem conduction and decreasing afferent sensory transmission, thereby modifying reticulo-thalamo-cortical mechanisms regulating arousal. The state of entropy measured by EEG-monitors has detected sedative effects associated with neuraxial anaesthesia in healthy volunteers, as well as during caesarean delivery. Entropy is a measure of the irregularity or disorder of a brains activity - sedation leading to a decrease of irregularity or disorder in the EEG.The aim of this pilot study is to prospectively assess the effect of spinal anaesthesia in healthy and preeclamptic parturients on brain activity. Decreased epileptiform activity in patients with preeclampsia would suggest that early neuraxial analgesia in labouring preeclamptic patients is beneficial, and may protect against neurological complications.
100 women with severe preeclanpsia received Magnesium sulfate 6 grams intravenous over 20 minutes as a loading dose. Resistance index [RI], pulsatility index [PI] and systolic/diastolic [S/D] ratio of the umbilical artery, uterine aryery and fetal middle cerebral artery before and repeated 20 minutes after intravenous administration of 6 grams of magnesium sulphate (loading dose) over 20 minutes . fetal breathing movements and fetal gross movements are counted within 20 minutes, before and after intravenous administration of 6 grams of magnesium sulphate (loading dose) over 20 minutes
Pre-eclampsia seems to be associated with a four to five times increase risk of later microalbuminuria and CKD which might suggest a possible direct renal damage from pre-eclampsia
The investigators seek to describe the composition, architecture, and electrical conduction properties of the human uterine myometrial artery and their impact on vascular reactivity upon exposure to hypertensive stress. Non-pregnant women and pregnant women with and without hypertensive complications will be studied to evaluate the influence of these states on the myometrial arteries. Vascular over-reactivity and disruption of the normal pregnancy-associated physiologic changes of relaxed vascular tone possess the potential for non-compensated blood flow to the uterus and placenta that is insufficient to meet the metabolic demands of a growing placenta. With an understanding of these changes, the research team will be able to propose basic mechanistic changes of pathologic myogenic tone that may ultimately be investigated as potentially modifiable processes to reduce the development and/or severity of these pregnancy complications (gestational hypertension, preeclampsia, eclampsia, small for gestational age, intrauterine growth restriction and intrauterine fetal demise. ).
