Oral Antihypertensive Regimens for Management of Hypertension in Pregnancy
Hypertension in PregnancyPreeclampsiaThis is a pragmatic, open-label, randomised control trial of three oral anti-hypertensive regimens for women with severe hypertension in pregnancy. Women presenting with severe hypertension in pregnancy in two hospitals in Nagpur, India will be randomised to one of three oral regimens: nifedipine, labetalol or methyldopa. This trial will compare the efficacy, safety and side effects of these three oral regimens for management of hypertension in pregnant women. The investigators hypothesize that nifedipine treatment of severe hypertensive parturient women is more effective than treatment with labetalol or methyldopa in controlling high blood pressure within six hours.
Hydralazine Versus Labetalol for the Management of Hypertensive Disorders of Pregnancy
HypertensionPregnancy InducedHypertensive crisis (defined as a systolic pressure > 160mmHg or a diastolic pressure > 110mmHg) in patients with a hypertensive disorder of pregnancy is a serious complication with severe and even deadly consequences. The management in this population had been studied, but no consensus has been reached with regards to which treatment is better. Our study will compare two drugs: Hydralazine and Labetalol for the management of hypertensive crisis.
Neonatal Sleep Intervention to Improve Postpartum Hypertension
Pre-EclampsiaGestational Hypertension1 moreThe investigators are conducting a single center, randomized controlled trial testing the impact of a neonatal sleep intervention, the SNOO, on reducing maternal blood pressure (BP) in the postpartum period in women with hypertensive disorders of pregnancy. The SNOO is a responsive bassinet designed to automatically calm and consolidate infants by responding to their cries. Use of the SNOO has been demonstrated to improve infant sleep by 1-2 hours nightly, thus increasing maternal sleep time. The investigators plan for 110 women with pregnancies complicated by gestational hypertension or pre-eclampsia to be randomized 1:1 to either receive and use the SNOO responsive bassinet for their infants, or to receive the usual care of safe sleep education. Women will be followed longitudinally through 6 months postpartum with serial BPs, weights, mood assessments, and subjective and objective sleep assessments. The investigators hypothesize that for women with pregnancies complicated by gestational hypertension or preeclampsia, that poor maternal sleep quality contributes to increased BP in the postpartum period. The investigators further propose that compared to usual care (safe sleep education), an intervention targeted to improve neonatal sleep (the SNOO), and thus maternal sleep, will improve postpartum BP for these women.
Arm and Finger Measurement for Blood Pressure Surveillance
HypertensionPregnancy-InducedAccurate blood pressure (BP) measurement is critical in peripartum care. The cuff and bladder sizes affects the accuracy of BP measurement. Current international BP measurement recommendations are based on mid-arm circumference (MAC). However, evidence have shown the discrepancies between these sizes, leading to inaccuracy of BP measurement. This study will measure arm and finger size of 300 parturients in third trimester to determine whether the MAC, finger measurement or body mass index (BMI) is the best clinical predictor for non-standard cuff sizes for BP measurement.
The CHIPS Trial (Control of Hypertension In Pregnancy Study)
Gestational HypertensionThe investigators do not know which approach to treatment of non-severe high blood pressure in pregnancy is better for women and babies. In the CHIPS Trial, the investigators seek to determine whether 'less tight' control (aiming for a diastolic blood pressure [dBP] of 100 mmHg), compared with 'tight' control (aiming for a diastolic blood pressure [dBP] of 85 mmHg) can decrease the risks of adverse baby outcomes without increasing the risk of problems for the mother.
CHIPS (Control of Hypertension in Pregnancy Study): A Pilot Trial
Transient HypertensionPregnancyPrior to undertaking CHIPS which will be a large and difficult trial, we believe we need to first determine whether clinicians will comply with the interventions of 'less tight' and 'tight' control of dBP, and whether the interventions will result in differences in mean dBP between groups. A pilot will also allow us to confirm the ability of centres to identify eligible women and the willingness of women to join CHIPS.
Fractionated Vs Single Dose Injection for Spinal C-Section in Patients With Pregnancy-Induced Hypertension...
Pregnancy Induced HypertensionThe 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
Hypertensive Disorders of Pregnancy - the Neonatal Burden of Disease
Hypertension in PregnancyAround one in ten women have high blood pressure in pregnancy. This is potentially serious, with risks to the woman and her baby. Whilst maternal deaths from high blood pressure in pregnancy are now rare in the UK, blood pressure problems in pregnancy still cause many stillbirths and early births. Studies have shown that women of Black and Asian backgrounds are more likely to have worse pregnancy outcomes when blood pressure problems in pregnancy develop. This study aims to: i) describe the burden of disease of high blood pressure in pregnancy amongst babies admitted to neonatal units on a national scale. ii) investigate outcomes for babies born to women with high blood pressure in pregnancy admitted to UK neonatal units across maternal ethnic groups. To complete this study, we will use the National Neonatal Research Database, which holds population-level data for all babies admitted to neonatal units (where unwell babies receive care) in the UK. We will look at records of babies admitted to neonatal units in England and Wales between 2012 and 2020. The records will include information on over half a million babies and their mothers. We will assess how many babies admitted to neonatal units were born to women who had high blood pressure in pregnancy. We will report the outcomes of these babies, and how they compare to babies born to women without high blood pressure in pregnancy. We will analyse whether outcomes for babies born to women with high blood pressure in pregnancy varies according to maternal ethnicity, and investigate what may be driving differences we find.
MIRACLE of LIFE Study
Preterm LaborPreterm Birth8 moreThe goal of this observational study is to develop and validate cell-free RNA-based biomarkers for predicting a variety of adverse pregnancy outcomes in a pregnant person population. The main question it aims to answer are: Can cell-free RNA-based biomarkers predict which pregnant people are at greatest risk of developing adverse pregnancy outcomes (e.g., preterm birth, preeclampsia)? What is the performance of such biomarkers when predicting an adverse pregnancy outcome (e.g., sensitivity, specificity, PPV, NPV, TPR)?
Breathing Exercise in Pregnancy-induced Hypertension
Pregnancy Induced HypertensionTo determine the effects of Breathing control vs Alternate nostril breathing on maternal cardiovascular parameters in pregnancy and to determine the effect of breathing control vs Alternate nostril breathing on Fetal Heart rate. Many evidence-based studies show breathing exercises have beneficial and useful effects on the hypertensive population and also have positive effects on pregnancy-induced hypertension.
