Filter by:The goal of this clinical trial is to learn about the impact of CPAP on the maternal and infant outcomes of women with obstructive sleep apnea syndrome. The main questions aim to answer are: [question 1]Explore the impact of different CPAP treatment times on the maternal and infant outcomes of pregnant women with combined OSAS; [question 2]Explore the effects of CPAP on placental weight and birth weight/placental weight ratio in OSAS pregnant women. The CPAP treatment group received standardized CPAP treatment and routine prenatal care, while the non CPAP treatment group and non OSAS group only received routine prenatal care.
The purpose of this study is observe outcomes before and after a change in clinical practice in the threshold for management of severe hypertension in pregnancy and the post-partum period. Outcomes will be observed for 10 months under the current (traditional) clinical blood pressure threshold for acute treatment of hypertension, which is >= 160 millimeters of mercury (mmHg) systolic blood pressure (SBP). This will be followed by one month of education about rationale for the new SBP threshold of >= 180 mmHg and change of clinical guidelines. Then, there will be 10 months of observation after adopting the updated clinical threshold for acute antihypertensive treatment (>= 180 SBP).
The purpose of this study is to test a new approach to blood pressure management in postpartum preeclampsia. There will be two groups of patients in this early stage single center trial. Both groups of study participants (observational and interventional) will be treated with standard blood pressure medications while undergoing continuous non-invasive blood pressure and near infrared spectroscopy (NIRS) monitoring for 24 hours. The interventional group will have personalized blood pressure targets according to results of NIRS monitoring which will be updated in real time.
The purpose of this investigator-initiated randomized control trial is to determine whether oral Nifedipine versus oral Labetalol is superior in controlling high blood pressures in the postpartum period.
- Preeclampsia (PE) affects ~5% of pregnancies. Although improved obstetrical care has significantly diminished associated maternal mortality, PE remains a leading cause of maternal morbidity and mortality in the world. - Term PE accounts for 70% of all PE and a large proportion of maternal-fetal morbidity related with this condition. Prediction and prevention of term PE remains unsolved. - Previously proposed approaches are based on combined screening and/or prophylactic drugs, but these policies are unlikely to be implementable in many world settings. - Recent evidence shows that sFlt1-PlGF ratio at 35-37w predicts term PE with 80% detection rate. - Likewise, recent studies demonstrate that induction of labor (IOL) from 37w is safe. - The investigators hypothesize that a single-step universal screening for term PE based on sFlt1/PlGF ratio at 35-37w followed by IOL from 37w would reduce the prevalence of term PE without increasing cesarean section rates or adverse neonatal outcomes. - The investigators propose a randomized clinical trial to evaluate the impact of a screening of term PE with sFlt-1/PlGF ratio in asymptomatic nulliparous women at 35-37w. Women will be assigned to revealed (sFlt-1/PlGF known to clinicians) versus concealed (unknown) arms. A cutoff of >90th centile will be used to define high risk of PE and offer IOL from 37w. - If successful, the results of this trial will provide evidence to support a simple universal screening strategy reducing the prevalence of term PE, which could be applicable in most healthcare settings and have enormous implications on perinatal outcomes and public health policies worldwide.
