Filter by:This study is intended to evaluate the feasibility of using VisAR augmented reality surgical navigation during placement of an external ventricular drain (EVD). The investigators are interested in confirming the design of the VisAR headset is compatible with this bedside procedure.
The proposed study aims to evaluate the CNS penetration of telavancin in a critically ill population using cerebrospinal fluid (CSF) drawn from external ventricular drains (EVDs) in patients who have had spontaneous subarachnoid hemorrhage (SAH). Patients with SAH were chosen as the target population because they frequently require prolonged admission to the intensive care unit and drainage of CSF in order to prevent hydrocephalus. The estimated sample size is 20 subjects. This is a prospective cohort of patients with SAH. Patients will be included if they have a spontaneous SAH, aged 18-65 years old, Hunt-Hess score of 1-4 & has an actively draining ventriculostomy. Subjects will receive telavancin 10mg/kg (maximum 1000mg) every 24 hours for 3 consecutive doses. Serial serum and CSF samples will be obtained. An 8-hour urine collection will be completed on study day 2 in order to define the patient's measured creatinine clearance.
The purpose of this study is to examine the safety and feasibility of using hyperpolarized metabolic MRI to study early brain metabolism changes in subjects presenting with head injury and suspected non-penetrating traumatic brain injury (TBI). This study will also compare HP pyruvate MRI-derived metrics in TBI patients with healthy subjects as well as Subarachnoid hemorrhage (SAH) patients to better understand if metabolic Magnetic resonance imaging scan (MRI) can improve our ability to diagnose a TBI. The FDA is allowing the use of hyperpolarized [1-13C] pyruvate (HP 13C-pyruvate) in this study. Up to 15 patients (5 with TBI, 5 with SAH, and 5 healthy volunteers) may take part in this study at the University of Maryland, Baltimore (UMB).
The goal of this prospective, multicenter, observational, cohort trail is to explore the pattern of brain temperature-brain pressure association in acute brain injury and to clarify its predictive value for prognosis and neurological function 30 days after acute brain injury.
The goal of this pilot randomized trial is to compare the effect of Multiple Electrolytes Injection Ⅱand saline on the occurrence of hyperchloremia within 72h of randomization in patients with aneurysmal subarachnoid hemorrhage(aSAH). A secondary aim was to provide data for the design and power of a large-scale, multicenter, randomized controlled trial.
A study in the use of the Narcotrend depth of anaesthesia monitor to record a) seizures, and b) monitor a level of sedation referred to as 'burst suppression', in sedated patients in the adult and paediatric intensive care. Studies have shown that patients in coma on the intensive care unit may have subclinical in addition to clinical seizures. Subclinical seizures are seizures that do not show any outward signs and may go undetected. The current gold standard of recording seizures in the intensive care unit is by non-invasive, continuous monitoring of the electrical activity of the brain by electroencephalography (cEEG) using cerebral function analysing monitor (CFAM). This is recorded with simultaneous video recording and is performed by Clinical Neurophysiology departments. There has been a steady increase in demand for this service over recent years. Additionally, CFAM / cEEG is labour intensive and expensive. If trends continue, the proportion of hospitals offering CFAM / cEEG will continue to rise, creating increased demand for specialist staff, of which there are a finite number. Depth of anaesthesia monitors are used by anaesthetists to assess the level of anaesthesia in sedated patients using specialised, automated EEG analysis and are now recommended by NICE (DG6) to tailor anaesthetic dose to individual patients. This study aims to investigate the utility of the Narcotrend depth of anaesthesia monitor to monitor for seizures and burst suppression on the adult and paediatric intensive care unit. These monitors are cheaper and more widely available with the scope to be used at every bed space requiring neuro observation on the intensive care unit. The study aims to recruit all patients who are referred for CFAM / cEEG monitoring at Nottingham University Hospitals (NUH) Trust over a 12 month period. These patients will undergo simultaneous recording using CFAM / cEEG and depth of anaesthesia monitoring.
The design of the present study will be a multicenter prospective observational protocol. Approximately 100 patients will be recruited over the 24-month period with Acute Brain Injury (trauma brain injury, intracerebral hemorrhage, subarachnoid hemorrhage, ischemic stroke), who in their acute phase of intensive care unit require placement of a catheter capable of monitoring intracranial pressure (intra parenchymal catheter or external ventricular shunt). In addition to all the intensive care provided by the most recent guidelines, patients will undergo measurement of optic nerve sheath diameter through ultrasonography. At least, three measurements will be performed within the first 3 hours after admission, within the first 24-48 hours, and at each invasive intracranial pressure value greater than 18 cmH2O. Those patients with intracranial pressure values greater than 35 mmHg. At the first intracranial pressure measurement, patients with eyeball disease or trauma will be excluded. Measurements will be performed following the CLOSED bundle. Analysis of the results will include correlation between the invasive pressure values and the mean value of optic nerve sheath diameter measurements in the two projections (sagittal and transverse). In addition, the correlation of the absolute value of invasive pressure detected with the ratio of the optic nerve sheath diameter measurement to the eyeball diameter measured always ultrasound will be sought.
The aim of this study is to increase the effectiveness of clinical monitoring of patients with acute cerebral insufficiency by improving the discriminative ability of the FOUR scale. To study the sensitivity and specificity of the FOUR scale as a clinimetric of chronic disorders of consciousness.
1. The primary aim of this study is to investigate the correlation between the length of ICU stay and a newly developed FIVE score in neuro-intensive care patients. 2. The secondary objectives are to evaluate the impact of the FIVE score on hospital length of stay, Modified Rankin Scale, and mortality, as well as to determine the correlation between the GCS, FOUR, and FIVE scores
An MRI study to examine the relationship between blood pressure and cerebral blood flow in patients with subarachnoidal hemorrhage and suspect or verified vasospasm.
