Filter by:The purpose of this study is to demonstrate proof of clinical concept that application of the Intrathoracic Pressure Regulator (ITPR) will result in an increase in Cerebral Perfusion Pressure (CPP) and a decrease in Intracranial Perfusion Pressure (ICP) in patients with head injury and elevated ICP, and to determine the optimal ventilation tidal volume (TV).
Intracranial hypertension (ICH) is a mortality risk factor in severe traumatic brain injury (TBI), in purulent meningitis, in hepatic encephalopathy and in Reye's syndrome. It is also a risk factor for severe neurologic sequelae in survivors. Intracranial pressure (ICP) monitoring is likely to guide therapeutics, and certain research on adults or on children, suggest that IH therapeutic approach, for instance for bacterial meningitis, would improve the prognosis. Two monitoring techniques are currently recommended. They are reference methods for ICP measure : - monitoring with intraventricular catheter, - intra-parenchymal monitoring using optical fiber catheter. Non invasive methods have been suggested, including ultrasound measurement of optic nerve sheath diameter (ONSD) which is the most interesting one. The ONSD measured ultrasonically is correlated with ICP level in adults with severe TBI. A diameter over 5,9 mm predicts ICH within the first 24 hours. In children, ONSD average values have been worked out, and an ONSD increase is found in children suffering from hydrocephalus with IH and in children with TBI. ICH precocious detection is fundamental in children sensitive to ICH because their cerebral development is not finished yet. Difficulties met for ICP monitoring implementation in infants and its invasive nature are often disliked by clinicians. A non-invasive exam is then essential to allow a better care of children with ICH in intensive care unit.
Hemodynamic instability occurs frequently during dialysis treatment and still remains as significant cause of patient mobility and mortality. Postoperative hemodynamic optimization has been proved to reduce morbidity in high-risk patients. Intracranial pressure increased can lead to further structural and functional impairment owing to its deleterious effect on the compromised microcirculation and metabolism. This study was to compare the intra-cerebral pressure (ICP) and hemodynamic parameters between the sustained low-efficiency dialysis (SLED) and continuous veno-venous hemofiltration (CVVH) in post- brain tramatic patients.
The purpose of this project is to determine during moderate rise of intracranial pressure (ICP) in awake patient, the change in autonomic function and its influence on cerebral and systemic haemodynamics.
There is statistically significant correlation between invasive measures of intracranial pressure (ICP) and non-invasive, real-time, continuous physiologic waveform data algorithms to predict ICP. Furthermore, characteristics within this physiologic waveform data will allow modeling for trend prediction of derived ICP information. Specific aims: 1. Develop models to estimate ICP and cerebral perfusion pressure (CPP) after traumatic brain injury in humans. 2. Predict and anticipate changes in ICP for preemptive management purposes. 3. Analyze characteristics of changes in ICP after treatment failure. 4. Analyze data to predict/anticipate confounding physiologic factors that affect ICP and its treatment. 5. Test the resulting models in real time.
Idiopathic Intracranial Hypertension (IIH) is a disease that affects mainly young people, and is associated with headache and loss of vision. The medical and surgical management of IIH is problematic and many patients are not treated effectively. Some cases of IIH are associated with severe stenosis of the large veins of the brain and various researchers have recently reported significant improvement in patients with IIH after the narrow veins of the brain were treated with a stent. Our project aims to evaluate the safety and long-term efficacy of venous sinus stenting in patients with severe IIH refractory to medical management.
Osmotic therapy is a mainstay in the treatment of intracranial hypertension after traumatic brain injury.This study proposes to compare two hypertonic saline agents in patients with traumatic brain injury.
The purpose of this study is to discover a mathematic equation to express the intracranial pressure-volume (P-V) curve and a single indicator to reflect the status of the curve.
This study examines the role of osmotic agents in controlling brain swelling in brain injured individuals. Two osmotic agents -- mannitol and hypertonic saline -- are in common use, and they will be compared in the context of a randomized clinical trial. The goal is to determine if these agent differ in their ability to control episodes of brain swelling.
The study goal is to compare the management of increased intra-cranial pressure (ICP) using 3% hypertonic saline vs. mannitol (given in same osmolar loads). Primary hypothesis: 1. Hypertonic saline will be non-inferior to mannitol in decreasing elevated ICP. Secondary hypotheses: 1. Hypertonic saline therapy will result with fewer complications than mannitol 2. ICP reduction duration will be longer using hypertonic saline when compared with mannitol
