Active clinical trials for "Hypoxia, Brain"

To compare the influence of two surgical anesthetic techniques, hypothermia with circulatory arrest or hypothermia with low-flow bypass perfusion, on neurologic functioning in infants undergoing heart surgery.

To assess the benefits of a new method of cardiopulmonary resuscitation, SC-V CPR (simultaneous compression and ventilation CPR) in terms of short and long-term survival and lessened cerebral dysfunction.

This research is being done to find out the safety of the investigational study drug, Clonidine Hydrochloride ( CLON). , in infants who are undergoing whole body cooling for the treatment of hypoxic ischemic encephalopathy (HIE). The only known and effective treatment for HIE is therapeutic hypothermia or whole body cooling for72 hours. During the cooling process, babies get agitated, shiver and are uncomfortable. To treat these side effects morphine is frequently used. CLON is very effective in decreasing shivering in adults and children. Furthermore, in some preclinical studies, clonidine has been shown to be neuroprotective (safe for the brain in models of brain injury)..This is a Phase I-II to determine if low dose CLON will reduce the incidence of shivering and whether it has short term cardiovascular safety. In this Phase I-II study, the investigators will determine the (i) the maximum tolerated dose of CLON during cooling for HIE, (ii) the effects of CLON on heart rate, blood pressure, core body temperature and cerebral autoregulation (ability to maintain constant blood flow to the brain) and (iii) association between blood levels and changes in the above parameters. In this study the investigators hope to find ways to improve sedation, shivering and agitation in newborn infants with HIE on the cooling protocol. Our ultimate goal is determine the potential neuro-protective properties of clonidine in newborn babies with HIE.

This study examines the potential benefits of a home stimulation program to treat infants who have suffered from brain asphyxiation (lack of oxygen). The program involves one year of stimulatory activities. Progress will be evaluated through neurological and behavioral exams.

Several projects in high altitude research in environments with a low oxygen partial pressure (hypobaric hypoxia) leading to hypoxemia showed, that cerebral perfusion and cerebral performance could be improved by adding C02 (cabon dioxide). The investigators hypothesize that adding 5% C02 to 02 (Oxygen) also under normobaric conditions increases the time until a significant cerebral hyopxia is measured by near infrared spectroscopy (NIRS) compared to the administration of 95% 02. lf this hypothesis proves to be true, this approach might be used in situations in which individuals are prone to cerebral hypoxia. In bariatric surgery, patients that experience an apnea phase are more prone to (cerebral) hypoxia due to the fact, that they have a higher body mass index (BMI) leading to a reduced functional residual capacity (FRC), which serves as the oxygen reserve in the body.

The aim of this study to evaluate the patients who underwent controlled hypotensive anesthesia under standardized depth of anesthesia; preoperative and postoperative blood HIF 1a, TAS, TOS measurement and cerebral perfusion evaluation with NIRS and to investigate tissue hypoxia secondary to hypotensive anesthesia and the changes of the mediators at the tissue level and which blood pressure parameters are related.

Studying the effect of passive versus Blanket roll III modality of therapeutic hypothermia (TH)on myocardial function of asphyxiated neonates through using tissue Doppler (TD).

Using the brain and the heart as index organs, perioperative interventions to optimize cerebral oxygen saturation and cardiac contractility in high-risk patients undergoing cardiac surgery should have a beneficial systemic effect for enhancing global tissue perfusion and improve outcomes.

The goal of this trial is to study, in three well-defined clinical situations responsible for cerebral hypoxia, the concentrations of biomarkers of thrombo-inflammation compared to a population of patients without cerebral hypoxia, and to study in patients with cerebral hypoxia the association between these concentrations and the clinical evolution.

Admission into a pediatric intensive care unit (PICU) is a highly stressful experience for child and family. High levels of stress can negatively impact outcomes, yet non-pharmacological interventions to decrease stress in the PICU are severely lacking. This is a prospective, single-arm feasibility trial that will explore the feasibility and acceptability of a music therapy intervention to decrease stress in the PICU among families of children receiving invasive or noninvasive mechanical ventilation. Objectives: The aims of this study are to: 1) Assess the feasibility of implementing a music therapy intervention in the PICU among children receiving invasive or non-invasive mechanical ventilation; 2) Determine the acceptability of the music therapy intervention in the ICU among caregivers, patients, and pediatric and cardiac ICU staff; 3) Explore the variability in child and caregiver stress outcomes throughout ICU admission. Hypothesis: The music therapy intervention will be feasible, as determined by recruitment, retention, protocol adherence, and data collection rates, and will be acceptable to participants and to PICU staff. Sample: This study will recruit 20 families that include children aged 2 months - 17 years old admitted with an expected length of ICU stay greater than 72 hours. Of these 20 families, the investigators will specifically recruit 10 families whose child is admitted for a hypoxic brain injury. Eligible children are receiving either noninvasive mechanical ventilation (i.e., continuous or bilevel positive airway pressure), invasive mechanical ventilation, or have an established tracheostomy tube and with escalated support settings. One primary caregiver will be enrolled along with the child admitted into the ICU.
