Filter by:Acute brain injury due to aneurysmal subarachnoid haemorrhage (SAH) or traumatic brain injury (TBI) is a condition with a high mortality, and surviving patients often have permanent disabilities. Multimodal neuromonitoring of intracranial pressure, brain tissue oxygen tension (PbtO2), and brain energy metabolism (measured with microdialysis (MD)) may help individualise the treatment of this patient group to protect the brain and potentially improve outcomes. However, there is still a significant lack of knowledge regarding the advantages and disadvantages of this type of monitoring. The present study consists of four substudies with the overall aim of examining which factors are most influential for regulating commonly measured intracerebral parameters such as oxygenation, glucose, and lactate. Additionally, the influence of these of parameters on functional outcome and mortality will be explored. The individual studies are detailed below:
This is a study of adult patients with a severe and sudden brain injury who have a drain placed in their brain to measure pressure. The purpose of the study is to monitor the pressure in the brain using a monitor placed on the forehead, and compare this to a drain placed in the brain.
In this study, we investigated the clinical variability in paroxysmal sympathetic hyperactivity in patients with acute brain injury and examined the prognostic value of the Paroxysmal Sympathetic Hyperactivity Assessment Measure (PSH-AM) in relation to Doppler ultrasound assessment of volume status, right heart function, and pulmonary edema. Thirty patients with ABI were prospectively enrolled. A correlation analysis between the PSH-AM score and related clinical indicators was performed using Pearson's or Spearman's correlation coefficient. Receiver operating characteristic curves were used to assess the prediction of the 6-month Glasgow Outcome Scale Extended score for neurorehabilitation prognosis.
Early prediction of outcomes after acute brain injury (ABI) remains a major unsolved problem. Presently, physicians make predictions using clinical examination, traditional scoring systems, and statistical models. In this study, we will use a novel technique, "SeeMe," to objectively assess the level of consciousness in patients suffering from comas following ABI. SeeMe is a program that quantifies total facial motion over time and compares the response after a spoken command (i.e. "open your eyes") to a pre-stimulus baseline.
The primary object of the study is to further characterize safety and feasibility of low-field bedside MRI in pediatric and neonatal ECMO patients. To perform imaging assessments of an early-stage magnetic resonance imaging (MRI) system on patients using low field magnetic strength. Collect qualitative data from the image assessments to optimize device performance using a low field magnetic resonance imaging device in a simulated use environment; Collect qualitative data from the image assessments using a high field magnetic resonance imaging, computed tomography and ultrasound devices. Generate anonymized image data for post-acquisition evaluation, performance measuring and planning for subsequent study size
The purpose of this research is to determine the effectiveness of using the Dynavision D2 to improve left neglect in adults with brain injury, and improve performance of ADLs/IADLs. This study will use a randomized control trial at Providence Care Hospital in Kingston Ontario, with clients admitted to the Stroke and ABI services who have been identified through the Catherine Bergego Scale (CBS) as having moderate to severe left neglect. Individuals will be randomly assigned to the control arm, where they will get the usual 60 minutes of OT treatment daily or the intervention arm, which is 30 minutes of their usual OT treatment and a 30 minute session of the Dynavision for 10 sessions for short stay inpatients (~ 3 weeks) and 20 sessions for clients with longer 5-6 week stay. The CBS will be used to measure change in neglect severity at three time points: baseline, following 10 sessions and following 20 sessions, for those that stay for longer.
This is an observational study of patients with severe acute brain injury, which aims to characterize the development of hyperglycaemia and hyperlactataemia and the influence of these markers on clinical outcome. Additionally, in a subgroup of patients undergoing advanced multimodal neuromonitoring on either clinical or research indication, the relationship between hyperglycaemia and brain glucose levels as well as systemic and microdialysis lactate will be examined.
This study aims to assess the feasibility of assessing acute brain injury using a portable low field MRI in patients on ECMO.
Despite almost universal usage of supplemental oxygen therapy in patients presenting in the emergency department with traumatic brain injury (TBI), optimal oxygen levels are unclear. The investigators propose a pilot multi-center randomized controlled trial to test the hypothesis that maintaining intermediate normal as opposed to high normal oxygen levels in patients presenting in the emergency department with TBI is feasible, and to obtain preliminary data on the efficacy of the two approaches to oxygen therapy. The aim is that the investigators produce pilot data, which could inform the design of potential subsequent larger clinical trials.
The study will provide information on cognitive impairment and Health related quality of life in patients surviving 12 months after acute brain injury, generate a hypothesis of useful variables to predict cognitive impairment or low levels of HRQoL, and potentially inform interventions for the prevention and treatment of cognitive impairment following neuro-ICU stay.
