Filter by:The purpose of the study is to help make a lower cost automatic blood pressure monitor device for diagnosis and monitoring of pre-eclampsia in pregnant women, where automatic blood pressure monitoring is limited or not available. The study will compare this low cost device to a commercially available system used for pre-eclamptic women in many United States hospitals that the investigators will be bringing to Malawi as a part of this study. The team hopes to show that this lower cost blood pressure machine works well and can help women with pre-eclampsia. The study also aims to see if this machine is easy for the nurse to use. 70 pregnant women who are either at-risk or diagnosed with pre-eclampsia will be enrolled at University of Texas Health Science Center Houston. Patient arm circumference will be measured with measurement tape. They will be seated upright in a comfortable chair with arm at heart level and an arm blood pressure cuff from either the automatic blood pressure monitor or a manual sphygmomanometer will be placed on the left arm. The cuff will be inflated and then deflated until measurement concludes. Heart rate will be measured with tactile arterial palpation.The process will be repeated for a total of up to nine measurements, alternating between measurements with the automatic blood pressure monitor and the manual sphygmomanometer. There will be a waiting period of 45-60 seconds between each measurement. The results of this study will help researchers understand the performance and usability of this device in Malawi and help decide if any design changes are needed.
There are huge doubts as to how long to keep postpartum magnesium sulfate. Studies demonstrating the usefulness for 24, 12 or 6 hours are of little evidence and do not take into account the use of magnesium sulphate before delivery. Termination of pregnancy is the best option to prevent eclampsia and magnesium sulphate has proven effective, but do not know the minimum effective dose.The investigators believe that if the patient has received less than 8 continuous hours of magnesium sulphate before delivery, maintain magnesium sulfate for 6 hours is as effective as keeping it for 24 hours.
Phase III two arm double-blinded randomised controlled trial to examine the effect of prophylactic low-dose aspirin from the first-trimester of pregnancy in women at increased risk for PET on the incidence and severity of the disease
Pre-eclampsia and eclampsia cause 50,000 deaths annually. While MgSO4 is a widely accepted and relatively inexpensive treatment for these conditions, barriers to delivery via IV injection in low-resource settings pose a large obstacle to reductions in mortality. AutoSyP is a low-cost, low-powered automatic syringe pump that could overcome this barrier to the delivery of MgSO4. We propose to conduct a pilot clinical evaluation of its ability to deliver MgSO4 to women with pre-eclampsia or eclampsia in Malawi. AutoSyP will be the subject of a 2 phase pilot clinical community trial in Malawi. Prior to the start of the study, all nurses will receive a 4-hour training on AutoSyP use to ensure proper procedures are followed. Phase 1 will be an initial validation of the clinical performance of the device delivering only standard IV saline to 10 stable women. The study will continue to Phase 2 where, the device will deliver MgSO4 to up to 40 women presenting with symptoms of pre-eclampsia. 1. Prior to the start of the study, all nurses will receive a 4-hour training on AutoSyP use. 2. Eligible and willing participants will provide informed consent. Then, baseline demographic and relevant medical history information will be collected. 3. In Phase 1, subjects will receive IV saline fluids by the Nurse. In Phase 2, the Nurse will provide loading dose of MgSO4 with the AutoSyP and research staff will monitor and record device performance and treatment specifications. 4. Subsequent maintenance doses of saline or MgSO4 will be administered and observations monitored and recorded for up to 24 hours as clinically indicated. Others may benefit from this study in the future as AutoSyP is a new delivery system is needed to break down the barriers to IV delivery of MgSO4 in low-resource settings. The results of this study will be made available to the Ministry of Health, NHSRC, COMREC, the College of Medicine Library, the Department of Paediatrics, and other partners working in neonatal and child health. Findings will be published in academic journals and conference proceedings in an effort to disseminate results to potential end-users. The research findings of this study will be critical in the evaluation of future interventions.
The research team has developed an automatic blood pressure monitor (Sphygmo) to be used for the monitoring and diagnosis of pre-eclampsia in pregnant women, particularly in low-resource settings where current monitoring is limited. 90 adult volunteers will be enrolled by researchers at Rice University. The participant will be seated in a comfortable chair with arm at heart level. Arm circumference will be measured and a blood pressure cuff will be placed on the arm. The cuff will be inflated and blood pressure measurements will be taken by a commercially available device and by the Sphygmo device. Blood pressure measurements from both devices will be recorded. The participant's blood pressure will be measured up to 9 times with a waiting period of 45-60 seconds between each measurement. The results of this study will be used to optimize the blood pressure detection algorithm and thus further develop the device.

The study also aims to see if this machine is easy for the nurse to use. 20 women who are either at-risk or diagnosed with pre-eclampsia will be enrolled at Queen Elizabeth Central Hospital. First, a nurse will fit the test device cuff on one arm of the subject and the commercially available cuff on the opposite arm. A trained research assistant and the nurse will record the blood pressure measurements and document any alarm indications made by each device. Blood pressure measurements will continue until monitoring is no longer clinically prescribed. The results of this study will help researchers understand the performance and usability of this device in Malawi and help decide if any design changes are needed.
Obesity is a growing problem in East London and every other woman who enters pregnancy is obese or overweight. In addition to obesity, other metabolic risk factors such as raised lipids, high blood pressure and diabetes increase pregnancy related complications such as preeclampsia and long term problems such as heart diseases, stroke and death. Preeclampsia, presenting as hypertension and proteinuria is a leading cause of maternal and fetal mortality and morbidity. Interventions that reduce cardiovascular events by modifying risk factors also have the potential to reduce the risk of preeclampsia. The investigators work funded by the National Institute of Health Research (NIHR) in the UK showed that dietary interventions in obese pregnant women may reduce the risk of preeclampsia. The investigators propose to show that pregnant women with metabolic risk factors derive the most benefit from a simple, targeted intervention based on Mediterranean dietary pattern to reduce the risk of maternal and fetal complications . Women with the risk factors (1230 women) will be randomly allocated to dietary intervention or usual antenatal dietary advice and the risk of maternal and fetal complications will be evaluated. The remaining eligible women who are consented for lipid tests, but do not have metabolic risk factors, will be followed up for outcome data only. Diet based interventions, especially those based on a Mediterranean dietary pattern has a potential to reduce the risk of preeclampsia. In the investigators study, pregnant mothers with risk factors will be randomly allocated to either a dietary invention or usual antenatal care and they will assess their composite maternal (pre-eclampsia or gestational diabetes) and fetal (stillbirth, small for gestational age or admission to neonatal intensive care unit) outcomes. The investigators will tailor the intervention to suit the individual needs of the mother and provide nuts and olive oil to improve compliance. The study will be undertaken across the three maternity units at Barts Health NHS Trust, which delivers 17,000 women/year and two other maternity units in England. The study is supported by the office of the Mayor of Tower Hamlets which will facilitate the involvement of grassroots workers to promote recruitment and uptake of the intervention.
Introduction: Pre-eclampsia is a multifactorial syndrome which occurs in hypertension and proteinuria in pregnant women over 20 weeks gestation. It is the leading cause of maternal complications such as pulmonary edema, which occurs in about 3% of severe preeclamptic having as one of the causes volume overload. Anesthetic procedures are frequent in this population, with replacement with crystalloid of the duct during cesarean section under spinal anesthesia for combat hypotension and hypovolemia manifested by oliguria. However, as water therapy have antagonistic effects on cardiopulmonary and renal systems is no doubt as to the benefits compared to conventional or restrictive pattern of fluid therapy on renal function. Objective: To compare the renal function of patients with severe preeclampsia who received restrictive fluid therapy during caesarean section, as well as evaluating the use of cystatin C and Neutrophil gelatinase-associated lipocalin (NGAL) as a predictor of renal damage in this population. Hypothesis: Intraoperative fluid restriction did not influence renal function of patients with severe preeclampsia undergoing cesarean section under spinal anesthesia.
Acid/base imbalances are not well understood in pre-eclamptics, and better tools are needed to allow a thorough and meaningful evaluation. Disorders of electrolytes and albumin are common findings [13, 14], and the impact of such disorders on acid-base homeostasis has increasingly been acknowledged [4, 15]. The purpose of this prospective case-control study is to evaluate acid-base status in 100 women with mild or severe pre-eclampsia and 25 healthy controls by applying the Stewart Fencl's physicochemical acid-base model. We hypothesize that several simultaneous, and possibly offsetting, metabolic acid-base disorders will be identified and quantified, and that these may be useful to guide clinicians in their medical management and indication for delivery. Intermediate and long-term goals are to evaluate the ability of the Stewart Fencl's physicochemical acid-base model to guide fluid management and predict maternal and neonatal outcomes.
We aim to compare carbetocin with misoprostol for the prevention of postpartum hemorrhage in patients with severe preeclampsia. The primary outcome is postpartum haemorrhage (blood loss of ≥ 500 ml) while our Secondary outcomes include use of additional uterotonics, need for blood transfusion, maternal adverse drug reaction, maternal complications and maternal death
