Filter by:To explore the cerebral protective effect of midazolam in patients with traumatic brain injury, we will collect blood samples from patients treated with or without midazolam when the patient is admitted to ICU, 24 h, 48 h and 72 h after the admission before the use of midazolam for patients in group N1, and before the patient is treated with midazolam, 24 h， 48 h, 72 h after the use of midazolam for patients in group N2. Parameters of cerebral metabolism and inflammatory response will be obtained from the blood samples or the cerebrospinal fluid. With the aforementioned parameters, the relationship between clinical outcome and cerebral metabolism and inflammatory response will be detected with statistical method.
Management of intracranial hypertension (ICH) in patients with severe traumatic brain injury (sTBI) is crucial to their survival and optimal recovery. The evidence-based Guidelines for the Management of Severe Traumatic Brain Injury, 3rd Edition recommends use of intracranial pressure (ICP) monitors to assess ICH and guide intervention. Unfortunately, only a small percentage of the world has the resources and capability to routinely monitor ICP. The objective of this proposal is to create and test guidelines for the treatment of severe TBI in the absence of ICP monitoring.
To test the safety and feasibility of a new treatment for adolescents who are slow to recover from a sport-related concussion, the investigators are conducting a randomised controlled trial comparing treatment as usual with an active rehabilitation program that involves sub-symptom threshold cardiac exertion, sport-specific coordination activities, and positive visualisation techniques.
Traumatic Brain Injury (TBI) is a common injury in combat, terrorist attacks and sports such as football and hockey. Unnecessary delays in the diagnosis and treatment of brain damage in patients who can benefit from evacuation procedures can lead to worse brain injury, worse outcome and, sometimes, unnecessary death. However, there is no reliable and sensitive method for diagnosis of TBI severity in the field. In this study we will examine the feasibility of using this a multifocal chromatic pupillometer for monitoring TBI, by examining the pupillary response to multifocal chromatic stimuli in intracranial pressure (ICP)-monitored severe TBI patients. As control, normal subjects will be tested for pupillary responses using this device.
1. Background: Preliminary studies have suggested that valproate acid (VPA) may promote neuron survival, inhibit apoptosis, decrease the neuron function deficit in cerebral ischemia, and promote the brain functional recovery after traumatic brain injury (TBI). Besides, in the guide of prevention and treatment of epilepsy in 2007, VPA was one of the antiepileptic drugs which were suggested to prevent early epilepsy after TBI (less than 7 days). 2. Objectives: Our main objective was to evaluate whether VPA could protect brain and improve recovery of brain function after severe TBI. The secondary objective was to explore whether VPA could prevent late epilepsy after severe TBI (more than 7 days). 3. Methods: We would enroll 160 patients who were in a vegetative or minimally conscious state 4 to 16 weeks after TBI and who were receiving inpatient rehabilitation. Patients were randomly assigned to receive VPA or placebo for 4 weeks and were followed for 2 weeks after the treatment was discontinued. The rate of functional recovery on the Disability Rating Scale (DRS; range, 0 to 29, with higher scores indicating greater disability) was compared over the 4 weeks of treatment (primary outcome) and during the 2-week washout period with the use of mixed-effects regression models.
Severe traumatic brain injury with increased intracranial pressure can lead to decreased cerebral blood flow. Low cerebral blood flow is responsible for secondary lesions, leading to bad prognosis. It is not yet established whether increasing cardiac output in these patients can lead to an increase in cerebral blood flow, although there are some arguments in favor of this hypothesis. The aim of this study is to demonstrate that increasing cardiac output will improve cerebral blood flow in patients with severe traumatic injury and high cerebral pressure.
The purpose of this study is to collect and compare information from cranial ultrasounds, magnetic resonance imaging scans, neurological exam and neuropsychological assessments of children. The investigators hope that the information collected in this study will help with early screening, diagnosis and treatment of brain injury in newborns as well as identify a connection between MR imaging (MRI-magnetic resonance imaging, MRS-magnetic resonance spectroscopy) and neurodevelopmental outcome.
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.
The main objective of this study is to describe differential cognitive processing of various stimuli by a population of control subjects and a population of patients with selective cognitive deficits or altered states of consciousness by using dedicated ERP paradigms and high-density EEG picked up system.
Mild traumatic brain injury (mTBI) is a prevalent and costly public health problem with disabling consequences. More than one million civilians with mTBI are treated in US hospitals and emergency departments each year (Faul, et al., 2010). While the exact number is debated, approximately 10-15% of individuals with mTBI will experience prolonged and disabling post-concussive symptoms (Stranjalis, et al., 2008; Ruff and Weyer Jamora, 2009), and 34% will experience a psychiatric illness in the first year after injury (Fann, et al., 2004). In addition, at least 188,270 military service members sustained a TBI from 2000 to mid August 2010, and nearly 77% of these injuries were mild (Defense and Veterans Brain Injury Center, 2010). Many individuals require treatment for resulting mTBI symptoms. The proposed study builds on preliminary research conducted by the investigators to develop and test the effectiveness of a social work delivered education and reassurance intervention for adults with mTBI (SWIFT-Acute) against usual care. The proposed study will assess acceptability and obtain preliminary effectiveness data for an enhanced social work assessment and intervention for adults with mTBI (SWIFT) discharged from the Emergency Department (ED). SWIFT includes early education, reassurance, coping strategies, resources and a brief alcohol use intervention in the ED plus follow up telephone counseling, needs assessment and case management referral to necessary services. The intervention targets cognitive, physical, psychiatric and functional outcomes; specifically, post-concussive symptoms, depression, anxiety, posttraumatic stress disorder, alcohol use, community functioning and successful linkage to community resources. It is hypothesized that SWIFT will be acceptable to patients and that participants in the SWIFT group will report superior outcomes on measures of post-concussive symptoms, depression and anxiety, alcohol use and community functioning and will report increased successful linkages to needed resources when compared to the SWIFT-Acute group. The specific aims of the study are: 1. Implement an innovative social work intervention for adults with mTBI (SWIFT). 2. Assess acceptability of SWIFT using qualitative interviews with participants. 3. Assess preliminary effectiveness of SWIFT compared to SWIFT-Acute alone on reduction or prevention of post-concussive symptoms, depression, anxiety, posttraumatic stress disorder (PTSD) symptoms, and alcohol use, and on improvement of community functioning and successful linkage to community resources. 80 participants will be randomized to receive SWIFT or SWIFT-Acute. Preliminary intervention effectiveness will be assessed using standard measures of post-concussive symptoms, the primary outcome, depression, anxiety, PTSD, alcohol use, and community functioning. A structured survey will be used to assess linkage to community resources.
