Prevalence of Trephined Syndrome After Decompressive Craniectomy

Decompressive craniectomy is frequently used to treat increased intracranial pressure or an intracranial mass effect. Trephined Syndrome describes a neurological deterioration, which is attributed to a large craniectomy. The symptomatology is varied but includes headache, aggravation of a hemisyndrome or cognitive disorders, often has an orthostatic component and improves or disappears with cranioplasty. The incidence of Trephined Syndrome has been reported between 7% and 26%. ...

Cerebral Oxymetry in Traumatic Brain Injury

Vasopressor for current treatment protocols for acute traumatic brain injury can lead to vasoconstriction and thus cerebral hypoperfusion that can be detected with cerebral oxymetry as a drop in SCO2.

Multimodal Monitoring of Cerebral Autoregulation After Pediatric Brain Injury

Various methods have been studied to evaluate autoregulation. However, there is currently no universally accepted technique to assess integrity of the cerebral autoregulation neurovascular system. In the last decade, significant progress has been achieved in developing methods to assess cerebral autoregulation by quantifying cross-correlation between spontaneous oscillations in CBF or oxygenation and similar oscillations in arterial blood pressure. In this study the inve...

Allogenic Cord Blood Transfusion in Patients With Cerebral Palsy

Cerebral palsy is a disorder of movement and posture resulted from a non-progressive lesion or injury of the immature brain. It is a leading cause of childhood onset disability. Many experimental animal studies have revealed that umbilical cord blood is useful to repair neurological injury in brain. On the basis of many experimental studies, umbilical cord blood is suggested as a potential therapy for cerebral palsy.

Avoiding Hypotension in Preterm Neonates

Objectives Firstly to examine in preterm neonates, whether it is possible to reduce number of hypotensive episodes and use of catecholamines by applying cerebral/peripheral near infrared spectroscopy in combination with predefined interventions and secondly to explore the potential impact on cerebral injury and mortality. Hypothesis By using predefined interventions for changes in cerebral/peripheral oxygenation ratio investigators will reduce hypotensive episodes and use of c...

Hyperventilation in Patients With Traumatic Brain Injury

Elevated intracranial pressure is a dangerous and potentially fatal complication after traumatic brain injury. Hyperventilation is a medical intervention to reduce elevated intracranial pressure by inducing cerebral vasoconstriction, which might be associated to cerebral ischemia and hypoxia. The main hypothesis is that a moderate degree of hyperventilation is sufficient to reduce the intracranial pressure without inducing cerebral ischemia.

Non-invasive Clinical Imaging of Cerebral Metabolism Following Brain Injury Using 13C Magnetic Resonance Spectroscopy.

Despite the decline in fatal traumatic brain injury (TBI) incidence in recent years, TBI morbidity remains a public health challenge and is the leading cause of disability in the United States To combat these effects, new research is needed to identify mechanisms of injury that will lead to potential targets for therapeutic interventions that improve neurological outcome. One promising area of research is the cerebral metabolic dysfunction following TBI. Studies of post-traumat...

Discrete Hypothermia in the Management of Traumatic Brain Injury

The primary goal of this project is to demonstrate the feasibility and clinical benefits of a new rapid treatment for secondary treatment for secondary brain injury called Discrete Cerebral Hypothermia System by CoolSystems, Inc., Berkley, CA. This device induced hypothermia in the adult brain without significant whole body hypothermia. Discrete Cerebral Hypothermia System holds a great potential for protecting the brain from the devastating secondary complications of trauma wi...

Positron Emission Tomography (PET) in Evaluating Cerebral Glucose Metabolism and Functional Change for Patients With Spinal Cord Injury

Background: Spinal cord injury (SCI) results in dysfunction of motor and sensory system and the hormonal secretion. Not only the change of peripheral hormonal organs, the central neurotransmitters were also affected. We consider there are some changes in cerebral physiology, anatomy or function after SCI. Objective: Use PET imaging to investigate the brain functional difference among the SCI and control group.

Diffusion-Tensor Magnetic Resonance Imaging (MRI) and the Evaluation of Perinatal Brain Injury

The researchers' objective is to use diffusion-tensor imaging (DTI) to evaluate infants diagnosed with cerebral white matter injury during the neonatal period and identify antenatal risk factors, electronic fetal heart rate monitoring abnormalities, and umbilical arterial gas results that are associated with cerebral white matter injury. The researchers' hypothesis is that this new imaging technique will help us better understand how these devastating injuries occur.

Frontal Bone Window in ICUF (FBW-ICU)

Transcranial doppler (TCD) is an established tool for monitoring flows in intracranial cerebral arteries. Its use is recommanded in the last guidelines on traumatic brain injury. The temporal bone window (TBW) is limited in evaluating flow in the anterior cerebral arteries (ACA) because of an unfavorable insonation angle. Thereby TCD could be unfit to detect a segmental lesion on the anterior cerebral arteries (ACA). The frontal bone window (FBW) is a promising approach in eva...

Remote Ischemic Conditioning Paired With Endovascular Treatment for Acute Ischemic Stroke

Ischemic stroke, which is due to the occlusion of a cerebral blood vessel, comprises nearly 90% of all strokes. Currently, reperfusion of the salvageable tissue via thrombolytic drug or endovascular treatment is the most effective strategy to reduce brain damage. However, after recanalizing the occluded vessels, subsequent reperfusion injury is inevitable. It may not only weaken the therapeutic effects of timely reperfusion but also impede patients' recovery. Moreover, thousand...

To study the reactivity of the mu rhythm during action and action-observation by EEG in children with unilateral cerebral injury.

Neurologic Injury Following Aortic Arch Replacement

Investigators are seeking to learn how well different cooling temperatures along with different blood flow pathways to the brain reduce the risk of injury to the brain in participants planning to undergo elective aortic arch and hemiarch surgery. Participants will be randomized to receive a cerebral protection strategy of either: deep hypothermic circulatory arrest and retrograde cerebral perfusion (DHCA+RCP) or moderate hypothermic circulatory arrest and unilateral selective a...

Cerebral Desaturation in Traumatic Brain Injury

We will determine the incidence and magnitude of cerebral desaturation in TBI. Adult patients (18 years and older) admitted to the Surgical/Trauma Intensive Care Unit (ICU) at the Health Sciences Center with a severe TBI will have cerebral oximetry monitoring instituted within 12 hours of admission and continuing for 72 hours after placement. Decreases in regional cerebral oxygenation will be correlated with ICU hemodynamic parameters including mean arterial pressure, intracran...

Neuroimaging and Neuromonitoring in Critically Ill Children With Sepsis

In critically ill children with severe sepsis, neurophysiologic derangements often proceed undetected and can lead to irreversible brain injury causing neurocognitive and behavioral deficits. The etiology of these impairments is unclear, however, it is likely that some of this neural injury is preventable. The overarching goal for this study is to show that acute acquired structural and microstructural brain injury occurs in critically ill children with severe sepsis, and that ...

A Pilot Study- Monitoring Cerebral Blood Flow in Neonates With Congenital Heart Defects

Congenital heart defects have an incidence of 9/1000 live births. Infants with congenital heart defects such as Transposition of Great Arteries / Hypoplastic Left Heart are at risk for brain injury because of concomitant brain malformations. Previous studies of cerebral MRI in infants with congenital heart defects showed that in 20-40% of cases there was preoperative brain injury and post operative with the same incidence. These findings are strongly associated with early and l...
