The aim of this study was to compare haemodynamic changes, total dose of ephedrin requirement, and level of sensory blockade between fractionated dose and single dose spinal anesthesia injection in obstetric patients with pregnancy-induced hypertension who underwent Caesarean section
Introduction Maternal and neonatal mortality continue to be to be prominent public health issues in sub Saharan Africa including Ghana, with slow progress made towards attainment of Millennium Development Goals (MDG) 4 & 5. Studies have identified poor quality of maternal and child healthcare as a major challenge to the prevention of neonatal and maternal deaths. Effective interventions are required to make significant inroads in these areas. Objective To evaluate the effect of a SMS text messaging intervention to support clinical decision making by frontline health care professionals on neonatal and maternal mortality. Methods We propose to conduct a randomized controlled trial in the Eastern region of Ghana, involving 8 intervention and 8 control districts. The intervention consists of text messaging of standard protocols for maternal and neonatal care to front line health care providers in the region. A total of 17,040 pregnant women who are receiving care (including antenatal, delivery and post-natal) at any of the hospitals in the selected districts in the region will be monitored through monthly aggregate data on outcome measures such as neonatal and maternal deaths from eclampsia, postpartum haemorrhage, puerperal sepsis, birth asphyxia, low birth weight and neonatal sepsis. Cord sepsis will also be included as neonatal sepsis for this study. Also, a quality of care assessment in four sampled districts to measure adherence to the safe motherhood protocol will be conducted. Stata software package.55 and MLwiN software version 2.2456 will be employed in data analysis. Descriptive analysis will be carried out to explore baseline characteristics of study groups while logistic regression will be applied to evaluate the effect of the intervention. A two-tailed statistical significant level of 0.05 will be used. Expected outcome We hypothesize that the intervention will improve both maternal and neonatal service delivery and health outcomes in the intervention areas.
The aim of this feasibility study is to test recruitment of participants into Phase 1 of the study and then the re-recruitment and retention of participants in Phase 2 of the study. The investigators will also be assessing the acceptability of recruitment strategy and data collection to participants. The effect of pre-pregnancy factors (biophysical, genetic, socioeconomic, behavioural and psychological) on obstetric, cardiovascular, socioeconomic, behavioural and psychological outcomes will all be examined.
The initial trial examined if fish oil supplementation during pregnancy could reduce the risk of pregnancy induced hypertension, intrauterine growth retardation, and preterm birth in pregnancies that were at increased risk of these complications. The study was designed as a multi-centre clinical trial based in 19 hospitals in seven countries in Europe.
This is an open labeled dose escalation safety study of vitamin B3-amide dietary supplementation in pregnant women with hypertensive complications of pregnancy. The investigators will enroll 5 pregnant women at 24-36 weeks' gestation with the diagnosis of hypertensive complications of pregnancy. If the woman is anticipated to remain undelivered for 48 hours after diagnosis she will receive vitamin B3-amide, 500 mg/day in a single daily dose, continuing for two weeks or until delivery, which ever occurs first. Maternal blood will be collected at baseline and 2 times per week to measure maternal LFTs and study markers (nicotinamide metabolites, sFlt-1-Soluble fms-like tyrosine kinase-1 and PlGF). The objective of this dose escalation safety study is to determine the safety of vitamin B3 amide dietary supplementation during expectant management of hypertensive complications of pregnancy.
Hypothesis:Sleep Disorders are very common during pregnancy but the their exact role in causation of pregnancy related disorders is yet to be determined. OSA can complicate pregnancy given the risk factors of weight gain, upper displacement of the diaphragm, and hormonal-induced hyperaemia of the nasopharyngeal passages. SDB confers the risk of hypertensive disorders of pregnancy and is associated with adverse maternal and foetal outcomes. The study would involve pregnant females which would be prospectively followed in pregnancy and post partum to know the prevalence of sleep disorders in pregnancy. Diagnosis of sleep disorders would be confirmed by overnight polysomnography and ambulatory blood pressure monitoring. Pregnancy outcomes, both maternal and fetal would be recorded and its relation with sleep disorders in pregnancy would be analysed.
Hypertensive disorders of pregnancy (HDP) are with 50.000 deaths every year one of the major causes of maternal mortality worldwide, especially in low and middle income countries. This trial aims to determine whether a daily dose of combined low-dose aspirin, calcium, vitamin D3, folic acid and vitamin B12 in pregnancy reduces the incidence of pregnancy-induced hypertension in women at risk. Secondary and tertiary objectives include other maternal and neonatal outcomes.
Preliminary data from the investigator's lab identified novel patterns of differential DNA methylation in genes regulating cardiovascular and metabolic function in blood from women during the first trimester of pregnancy who were destined to develop preeclampsia (PE) in the third trimester. Further, common patterns of differential DNA methylation were found in the common genes from placental tissue at time of birth in the same women after diagnosis with PE, suggesting that the epigenomic patterns that predict pregnancy-induced hypertension may also underlie the development of chronic hypertension years after. It is unknown whether aberrant DNA methylation in pregnancy-induced hypertension is the mechanism by which chronic hypertension develops in these women remote from pregnancy nor is it known if hypertension remote from PE is as responsive to therapeutic treatment of hypertension compared to women who develop hypertension without history of PE. The investigators plan to objectively test the central hypothesis and attain the objective of this project
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.
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.
