Hypovitaminosis D in Neurocritical Patients
Craniocerebral TraumaIntracranial Aneurysm8 moreVitamin D has been shown to impact prognosis in a variety of retrospective and randomized clinical trials within an intensive care unit (ICU) environment. Despite these findings, there have been no studies examining the impact of hypovitaminosis D in specialized neurocritical care units (NCCU). Given the often significant differences in the management of patients in NCCU and more generalized intensive care units there is a need for further inquiries into the impact of low vitamin D levels in this specific environment. This study proposes a randomized, double-blinded, placebo-controlled, single center evaluation of vitamin D supplementation in the emergent NCCU patient population. The primary outcome will involve length-of-stay for emergent neurocritical care patients. Various secondary outcomes, including in-hospital mortality, ICU length-of-stay, Glasgow Outcome Score on discharge, complications and quality-of-life metrics. Patients will be followed for 6 months post-discharge.
Hyperventilation in Patients With Traumatic Brain Injury
Head Injury TraumaHyperventilationElevated intracranial pressure is a dangerous and potentially fatal complication after traumatic brain injury. Hyperventilation is a medical intervention to reduce elevated intracranial pressure by inducing cerebral vasoconstriction, which might be associated to cerebral ischemia and hypoxia. The main hypothesis is that a moderate degree of hyperventilation is sufficient to reduce the intracranial pressure without inducing cerebral ischemia.

Study of Povidone Iodine to Reduce Pulmonary Infection in Head Trauma and Cerebral Hemorrhage in...
Ventilator Associated PneumoniaHead trauma and severe cerebral hemorrhage are major risk factors for development of ventilator-associated pneumonia. In a previous open labelled, single center study the investigators showed that repeated oropharyngeal decontamination with povidone-iodine may be an effective strategy to decrease the prevalence of ventilator-associated pneumonia in patients with head trauma. The present study aims to confirm these results in a multicenter, double blind study including patients suffering from head trauma or cerebral hemorrhage.
Phase III Double Blind Trial of Valproate Sodium for Prophylaxis of Post Traumatic Seizures
Post-Traumatic Seizure DisorderHead InjuriesOBJECTIVES: I. Determine whether treating head injured patients with valproate sodium will reduce the risk of developing seizures as a result of the head injury. II. Determine the safety of valproate, the appropriate dose, and the effect valproate may have on the recovery of the brain's ability to compute numbers, solve problems, remember information, and control the movement of limbs after head injury.
Bispectral Index Value Changes During Induction and Surgical Decompression in Head Injury Patients...
Traumatic Brain InjuryThis study was conducted in two parts: This first part was designed to determine thiopentone dose requirement for induction of anaesthesia with and without the use of Bispectral Index monitoring - Participant and Care Provider in appropriate study arm blinded. As a secondary outcome, Bispectral index monitoring was used to observe changes in neuronal function in intraoperative period as well as haemodynamic changes intraoperatively - Participant and Care Provider blinded.
Pilot Study Assessing the Feasibility of Treating Foot Drop With the Neurostep™ System.
StrokeCraniocerebral TraumaThis pilot feasibility study is assessing the safety and technical performance of the Neurostep™ System for the restoration of independent gait in subjects with gait disorder (i.e. foot drop) secondary to a CNS lesion (e.g. stroke).
Effect of Joint Mobilization on Alpha Motoneuron Reflex Excitability
Muscle SpasticitySpinal Cord Injury2 moreObjective: To determine the effect of ankle joint mobilization on the alpha motoneuron reflex excitability of the soleus muscle in people with spasticity. Subjects and Methods: A controlled clinical trial with crossover design and simple masking was conducted in 24 randomized subjects to initiate the control or experimental group. Traction and rhythmic oscillation were applied for five minutes to the ankle joint. Alpha motoneuron reflex excitability was assessed by measuring H wave amplitude (Hoffmann reflex - H reflex), stimulating the tibial nerve at the level of the popliteal fossa and recording in the soleus muscle. In each subject 12 measurements were taken: basal rate, during and after mobilization. Changes in alpha motoneuron reflex excitability were calculated in relation to basal measurement. For each measurement a hypothesis test was performed (Student t test). Results: In groups of patients with brain injury (BI) and incomplete spinal cord injury (ISCI), a significant difference was found between measurements of both studies, concerning variation in alpha motoneuron reflex excitability during the application of joint mobilization techniques, with a decrease in the experimental group and an increase in the control group. In contrast, no significant differences were found after mobilization therapy. Patients with complete spinal cord injury (CSCI) showed no significant differences in any measurements. Conclusion: We demonstrate the effectiveness of passive movement in the decrease of muscle tone during the mobilization maneuver in patients with BI or ISCI, but no residual effect after completion of the trial. This research project showed no evidence regarding spasticity reduction in complete spinal cord injuries. This suggests that therapeutic interventions to decrease muscle tone, based on the passive exercise and stimulation of proprioceptors should be reconsidered.
Magnesium Sulfate For Brain Injury
Brain InjuriesHead Injury1 moreThe purpose of the study is to determine whether magnesium sulfate, given within 8 hours of a moderate or severe traumatic brain injury improves survival, decreases the number of people developing seizures, improves the survivors' mental and psychological functioning, including the ability to return to daily life, live independently, and return to work or school.
Exercise in Patients With Post-Concussion Symptoms
Craniocerebral TraumaHead Injury4 morePhysical activity and exercise have traditionally not been much of a focus in treatment of postconcussion symptoms and posttraumatic headache. On the contrary, patients have often got advice to rest until they were free from symptoms. This approach, however, is challenged, and complete rest should probably be discouraged after the first 24-72 hours. Moderate aerobic exercise has been found promising in the early phase after sports-related concussion, and in the treatment of patients with headache. This study is an open pilot-study of guided, home-based exercise in a clinical sample with postconcussion symptoms and posttraumatic headache after mixed-mechanism mild traumatic brain injury and minimal head injuries. The study will result in data about the feasibility and possible effects of exercise as treatment for prolonged postconcussion symptoms and posttraumatic headache.
