Filter by:INTRODUCTION: Most studies on analgesia in pregnant women in labor mainly evaluate the effect of anesthetics on pain, mentioning hypotension as a side effect without investigating its impact on fetal well-being. The objective of the present study is to evaluate the efficacy of the use of low doses of local anesthetic (LA) to prevent hemodynamic alterations that manifest as a loss of fetal well-being. METHODOLOGY/DESIGN: It is a randomized clinical trial. Patients will be pregnant women in labor (dilation period) who want epidural anesthesia (EA), who will randomly receive 0.125% levobupivacaine (Group L) versus 0.2% ropivacaine (Group R). In both groups, controls of hemodynamic parameters and their relationship with changes in fetal heart rate (FHR) and cardiotocographic recording (RCTG) will be carried out during the first 60 minutes after the administration of the local anesthetic via the epidural route. In case of hypotension and/or subsequent FHR and RCTG alterations, they will also be recorded. The follow-up period will extend from the moment the patient enters the delivery room and requests epidural anesthesia until the moment the patient is discharged from the delivery room. The percentage of patients with hemodynamic alterations will be evaluated as a primary result, as well as the percentage of patients whose hemodynamic alterations are related to changes in FHR and RCTG, when using low doses of LA. In the following will also be evaluated in relation to analgesia, the onset time, level reached and degree of satisfaction; and various intra and postpartum side effects. DISCUSSION: Both groups of pregnant women in labor will be studied in order to obtain data on the potential impact of the use of low doses of local anesthetic via the epidural route on hemodynamic parameters and the state of well-being of the fetus.
In cases diagnosed as idiopathic polyhydramnios and healthy pregnancy between 24-40 weeks (total number of cases (100-120)), prospective fetal echocardiography will be performed to evaluate MPI and EFT.
In one of the most severe congenital heart defects, hypoplastic left heart syndrome (HLHS), the left ventricle is underdeveloped and the prognosis is worse than in most other heart defects. The underdevelopment can occur gradually during fetal growth caused by a narrowing of the aortic valve. At some international centers, such fetuses are treated with a balloon dilation of the narrowed valve, but there is no scientifically sound evidence that this treatment is effective. The aim of this study is: 1/ to evaluate whether balloon dilation during the fetal period of a narrowed aortic valve can reduce the risk of the left ventricle becoming underdeveloped and the baby being born with a so-called univentricular heart (HLHS); 2/ to investigate whether such treatment improves the prognosis for this group of children with a very complex and severe heart defect and 3/ to also describe side effects and risks in fetuses and mothers of the fetal procedure.
The study aims to assess the presence of fetal cardiac remodeling and dysfunction in singleton pregnancies conceived by assisted reproductive technology (Biopsied and Non-Biopsied ICSI) as compared with those conceived spontaneously (SC).
The aim of this clinical prospective study is to investigate the value of fetal cardiac magnetic resonance imaging using a new Doppler ultrasound based gating method for the detection of congenital heart desease.
Each year world-wide, 2.5 million fetuses die unexpectedly in the last half of pregnancy, 25,000 in the United States, making fetal demise ten-times more common than Sudden Infant Death Syndrome. This study will apply a novel type of non-invasive monitoring, called fetal magnetocardiography (fMCG) used thus far to successfully evaluate fetal arrhythmias, in order to discover potential hidden electrophysiologic abnormalities that could lead to fetal demise in five high-risk pregnancy conditions associated with fetal demise.
To assess whether the aCQM-Strain ultrasound method allows a good analysis of fetal cardiac function. Establish normality parameters and compare it with fetuses with risk factors of cardiac dysfunction.
