Filter by:Several studies in healthy volunteers have suggested that the synchronized functional connectivity in the DMN (Deafult-Mode Network) would sustain the mental content at rest, and when required, a switch in the activity between the DMN and other networks involved in specific congnitive functions, would occur. This interaction permit to make the hypothesis, that baseline brain activity is likely to shape our ongoing " stream of consciousness " and could correlate with conscious perception. The investigators hypothesized that DMN connectivity strength would be related to the level of consciousness of brain-damaged patients. The investigators will follow severely brain-injured patient in coma. Clinical examination using standardized behavioural scales: FOUR score (Full Outline of UnResponsivess), Coma Recovery Scale-Revised); and brain imaging assessesments using MRI (functional and anatomical connectivity, cortical thickness) will be performed at: 3 to 30 (visit 1), and 60 (visit 2) days after insult. If patient recover a normal conscious state between 30 and 60 days, an additional clinical and brain imaging assessment will be performed to identify related changes in brain activity (visit 1*) Monitoring of vital parameters will be performed in patients by a senior anaesthesiologist throughout the experiment.
The purpose of this study is to understand mechanisms associated with the development of coma during hepatic failure. As of today, those mechanisms are not understood and it is difficult to intervene and prevent coma development which is often associated with mortality. Understanding the mechanism involved, may allow us to prevent coma and develop new therapies to treat this disease.
The purpose of this study is to evaluate the use of combined clinical-neurological, neurophysiologic, neuroradiological and biochemical markers in prognostication after cardio- and/or respiratory arrest.
Objectives: (1) To check music and voice message influence on vital signs and facial expressions of patients in physiological or induced comas; (2) To connect the existence of patient's responsiveness with the Glasgow Coma Scale or with the Ramsay Sedation Scale. Method: This was a randomized controlled clinical trial with 30 patients, from two Intensive Care Units, being divided in 2 groups (control and experimental). Their relatives recorded a voice message and chose a song according to the patient's preference. The patients were submitted to 3 sessions for 3 consecutive days.
The aim of the proposed study is to determine if specific training in management of general, obstetric, neonatal and pediatric emergencies results in a change in practice of doctors working in emergency departments of public sector hospitals in three districts of Pakistan. The overall goal of the proposed study is to test the ability of a standard course (5-days training) to promote the provision of effective and evidence based practices in public sector hospital settings.
New single use laryngoscope metal blades are available for intubation. This type of blade is safer than the reusable ones concerning the interhuman cross infection risk. No clinical studies have compared the two types of blades in the emergency context. The primary aim of this study is to demonstrate that single use blades are as efficient as the reusable ones concerning intubation conditions.
This study will involve the use of therapeutic hypothermia. This prospective cohort pilot study will evaluate the clinical performance of a new device, the ThermoSuit™ System, to achieve therapeutic hypothermia in comatose patients following resuscitation from cardiac arrest, and the impact of the vasodilator, magnesium sulfate, on cooling performance and hemodynamics in these patients. The study hypothesis is that magnesium sulfate will significantly increase the rate of cooling.
Stroke, traumatic head injury, subarachnoid hemorrhage and cerebral anoxia are main causes of a coma condition implying severe brain damage and thus, poor prognosis. Clinicians are often in need for a tool able to predict the awakening of these patients. Multimodal MRI, associating the traditional morphological sequences with spectroscopy-MRI (MRS) and the diffusion tensor imaging, could provide such a prediction.
The optimal method of clearing the cervical spine in obtunded trauma patients is unclear. Computed tomography (CT) identifies most injuries but may miss ligamentous injuries. Magnetic resonance (MR) imaging has been widely used to exclude ligamentous injuries. We postulate that with the new generation of CT scanners, MR imaging is not needed to rule out significant injuries. Our protocol for clearing the cervical spine in obtunded trauma patients depends on CT alone. We are prospectively following these patients and performing a clinical examination when they are awake to show this is a safe approach.
The purpose of the study is to determine whether familiar vocal stimulation, provided during coma recovery, improves outcomes for persons who are unconscious after severe TBI. The primary hypothesis is that unconscious persons who receive standard rehabilitation (SR) plus a high-dose of Familiar Voice stimulation (FVs) compared to unconscious persons who receive SR plus a sham stimulation (Sham Group) will demonstrate: 1. Significantly more neurobehavioral functioning post-intervention compared to pre-intervention. 2. Using Functional Magnetic Resonance Imaging (fMRI), significantly higher average measures of volumetric activity in the whole brain, middle temporal gyrus bilaterally, primary auditory area, bilateral pre-frontal cortex, hippocampus and/or the cerebellum post-intervention compared to pre-intervention.
