Filter by:This study is being conducted to determine what dexmedetomidine does to the body and in turn, what how the body handles the medication. This medication, for the purpose of this trial, is used as a short-term sedative for infants who are immediately post-operative from cardiac surgery and have a breathing tube and are breathing with the assistance of a mechanical ventilator or breathing machine.
The purpose of this study is to determine if children with heart disease where there is only one pumping chamber("ventricle") have proteins (biomarkers") in the blood that can be used to monitor the function of their heart.
Brain problems occur in neonatal open heart surgery with a frequency of 20-70%, seen on neurological examination, brain imaging such as magnetic resonance imaging (MRI), or long term development problems such as learning disorders and hyperactivity syndromes. This study aims to determine if erythropoetin, a natural hormone made in the body, protects the brain from damage when given in high doses before and during neonatal open heart surgery. We will use brain MRI, brain wave tests (EEG), neurological examination, and long term developmental outcome testing to see if erythropoetin is better than salt water injection (placebo) in protecting the brain.
In this study, the investigators will evaluate the effect of sildenafil on exercise tolerance in patients with a single cardiac ventricle who have undergone the Fontan operation. The investigators will also evaluate echocardiographic measures of ventricular function and measure quality of life changes using two validated quality of life measures. The hypothesis is that sildenafil will result in increased exercise tolerance in patients who have had the Fontan operation as compared to placebo.
We believe that how a baby with Hypoplastic Left Heart Syndrome (HLHS)does after a major open heart operation, measured by things like blood pressure, oxygen saturation, heart rate and others, may have an impact on development. Studying how post-operative condition impacts outcomes may help us to protect babies better when they undergo surgery. This study will look at some of the long-term outcomes of children with HLHS, including both mental development and quality of life. We will use information from your child's medical record to see if early oxygen delivery has an impact on later development.
There have been many improvements in the care of children with hypoplastic left heart syndrome (HLHS). This has helped these children survive longer. Because these children now live longer, researchers are recognizing developmental disabilities (the children are behind in their thinking or physical activity) in children with hypoplastic left heart syndrome. The purpose of this research study is to help the investigators learn more about developmental disabilities in children with hypoplastic left heart syndrome. During the time of your child's first surgery for hypoplastic left heart syndrome, a monitor was placed on your child's forehead to measure the oxygen levels in the brain. This monitor is called Near Infrared Spectrometry (NIRS). The researchers involved in this study want to know if oxygen levels in the blood vessels of the brain have any effect on developmental disabilities later in life in children with hypoplastic left heart syndrome. The researchers plan to enroll 60 research subjects.
The objective of this research proposal is to perform an ongoing single institution prospective clinical trial examining the overall clinical outcome of children with single ventricle physiology.
Due to the small size of infants and the use of bypass machines, physicians have difficulty assessing whether the infant's brain and body is getting enough oxygen during heart surgery. This study compares continuous monitoring via the NIRS (Near Infrared Spectroscopy) to the traditional methods of determining oxygen saturation.
This is an exploratory study designed to evaluate the incidence of, and to quantify sleep disordered breathing following stage I Norwood reconstructive surgery. Sleep disordered breathing will be correlated with: 1. Elevations in pulmonary vasculature resistance at the time of Stage II surgery. 2. Risks of death
