This is a clinical study comparing the physiologic effects of two hypertonic solutions (mannitol, hypertonic saline) with a particular emphasis on changes in cerebral blood flow in patients with intracranial hypertension following serious traumatic brain injury (TBI).
This is a study comparing effects of two hypertonic solutions (mannitol, 6.4% hypertonic saline) on intracranial hypertension, cerebral blood flow, serum/urine osmolarity in patients with increased intracranial pressure caused by traumatic brain injury. The study is conducted during first 72 hours after the injury without any interference with standard medical treatment as performed at the institution. When the hypertonic solution is indicated by caregiver, the study team is informed and performs a set of physiologic bedside measurements including evaluation of cerebral blood flow and changes in plasma and urine osmolarity. The study is noninvasive and the study protocol does not hamper, in any way, standard care of treatment for these patients.

The purpose of this study is to determine whether hypertonic saline is as much effective as mannitol to treat intracranial hypertension after traumatic brain injury and has at least the sa...
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. ...
The purpose of this study is to evaluate the effect of Hypertonic Saline 7.5% vs Mannitol 20% on brain bulk (using a 4 point scale), intracranial pressure (subdural catheter)and the change...
The purpose of this study is to determine if hypertonic saline with and without dextran can improve neurologic outcomes in victims of severe traumatic brain injury (TBI). Injury and lost ...
The purpose of this study is to determine whether mannitol is as effective as hypertonic saline solution in the treatment of elevated intracranial pressure in patients with brain injury.
Hyperosmolar therapy is regarded as the mainstay for treatment of elevated intracranial pressure (ICP) in traumatic brain injury (TBI). This still has been disputed as application of hypertonic saline...
The primary aim of this paper is to investigate the neuroprotective and antiinflammatory effects of mannitol on optic nerve injury after acute traumatic subarachnoid hemorrhage and brain injury in rat...
Examine the prevalence of weight classifications and factors related to obesity/overweight among persons 1 to 25 years following traumatic brain injury (TBI) using the Traumatic Brain Injury Model Sys...
To investigate differences in longitudinal trajectories of ventricle-brain ratio (VBR), a general measure of brain atrophy, between Veterans with and without history of mild traumatic brain injury (mT...
To conduct a review of literature and quantify the effect that traumatic brain injury (TBI) has on oculomotor functions (OM).
Hypertonic sodium chloride solution. A solution having an osmotic pressure greater than that of physiologic salt solution (0.9 g NaCl in 100 ml purified water).
Prolonged unconsciousness from which the individual cannot be aroused, associated with traumatic injuries to the BRAIN. This may be defined as unconsciousness persisting for 6 hours or longer. Coma results from injury to both cerebral hemispheres or the RETICULAR FORMATION of the BRAIN STEM. Contributing mechanisms include DIFFUSE AXONAL INJURY and BRAIN EDEMA. (From J Neurotrauma 1997 Oct;14(10):699-713)
A form of acquired brain injury which occurs when a sudden trauma causes damage to the brain.
Acute and chronic (see also BRAIN INJURIES, CHRONIC) injuries to the brain, including the cerebral hemispheres, CEREBELLUM, and BRAIN STEM. Clinical manifestations depend on the nature of injury. Diffuse trauma to the brain is frequently associated with DIFFUSE AXONAL INJURY or COMA, POST-TRAUMATIC. Localized injuries may be associated with NEUROBEHAVIORAL MANIFESTATIONS; HEMIPARESIS, or other focal neurologic deficits.
Traumatic injuries to the cranium where the integrity of the skull is not compromised and no bone fragments or other objects penetrate the skull and dura mater. This frequently results in mechanical injury being transmitted to intracranial structures which may produce traumatic brain injuries, hemorrhage, or cranial nerve injury. (From Rowland, Merritt's Textbook of Neurology, 9th ed, p417)
Anxiety is caused by stress. It is a natural reaction, and is beneficial in helping us deal with tense situations and pressure. It is deterimental when is becomes an excessive, irrational dread of everyday situations. The most common types of anxiety di...
Of all the types of Dementia, Alzheimer's disease is the most common, affecting around 465,000 people in the UK. Neurons in the brain die, becuase 'plaques' and 'tangles' (mis-folded proteins) form in the brain. People with Al...
