Filter by:Background: One third of all ICH patients require intubation and mechanical ventilation and 1/3 of all ventilated patients require tracheostomy (i.e.≈10% of all ICH patients require tracheostomy). As shown previously, predisposing factors for tracheostomy are hematoma volume, hemorrhage location, presence of intraventricular hemorrhage (IVH), and occlusive hydrocephalus as well as presence of COPD (Huttner HB et al 2006 CVD). Sustained restricted vigilance and impaired consciousness after ICH is likely to result in failure of extubation, raise in incidence of ventilator-associated pneumonia, increased amount of sedative drugs and prolonged duration of neurocritical care. Hence an early tracheostomy may be beneficial in terms of reduced duration of mechanical ventilation. Basic hypothesis: Compared to patients with conventional ("late") tracheostomy between day 12 - 14, patients with "early" tracheostomy within 72h after admission will have: - shorter cumulative time of mechanical ventilation - less incidence of ventilator-associated pneumonia - less consumption of sedative drugs - shorter duration of stay in neurocritical care unit Randomization: Consecutive eligible patients are randomly assigned to Either "early" tracheostomy within 72h after hospital admission Or "late" tracheostomy (= control group; undergoing conventional tracheostomy between day 12 - 14 if extubation fails) Both groups receive plastic tracheostomy
The purpose of this study is to find out what effects, good and bad, the medication Albumin has on subjects who have experienced a type of stroke known as an intracerebral hemorrhage (ICH). An ICH is when spontaneous bleeding into the brain occurs due to fragile blood vessels. This research is being done because currently there is no effective treatment for ICH. However, study investigators believe that Albumin, the medication being tested in this study, is safe and may help improve patient recovery from ICH over time. Subjects will be enrolled in the study for a total of 90 days. Following enrollment, subjects will be randomized to receive 3 daily injections of either Albumin or Placebo (liquid with no drug), and will receive 3 brain MRI scans (with and without contrast), as described below. All subjects will be monitored continuously through 96 hours after enrollment (5 days) in the Georgetown ICU. Blood tests and clinical evaluations of neurological status, consisting of questions about subjects' functional abilities and medical history, will occur in the Georgetown ICU once every 24 hours through post-enrollment Day 5. Additionally, subjects will receive daily chest x-rays, and daily EKGs (exams that monitor how your heart is doing by placing electrodes, or small monitors, on your skin in specific locations). Similar clinical evaluations will occur at Day 30 and Day 90. Should subjects be discharged at these time points, day 30 assessments will occur over the phone, and day 90 assessments will occur in-person at Georgetown University Medical Center.
Head 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.
Context: A major lack of organ donors is a serious public health problem. It determines a prolonged delay before a transplant can be performed and thus a significant number of deaths of patients waiting for transplantation. The aim of this project is to reduce the delay of the diagnosis of brain death, and also to improve its diagnosis in the Intensive Care Unit. The diagnosis of brain death is strictly defined by the law and relies either on two consecutive flat electroencephalograms recorded at an interval of four hours, or on the lack of cerebral circulation during a brain angiography performed after suspecting brain death on the clinical exam. However, in usual practice, it is difficult to have all the needed clinical arguments, and their interpretation can be difficult in the pathological context. This may participate in the delay and the lack of patients potentially donors. Pre-study: In a pilot study, fifty subjects with severe cerebral lesions, had a continuous ECG recording. The investigators could find that a decrease in autonomic nervous system activity, as measured through the ECG, was correlated to the transition to brain death assessed by cerebral angiography. The loss of cardiac variability was always observed between two cerebral angiographies, one before and the second after brain death. This study allowed the investigators to calculate the threshold values of sympathetic and parasympathetic activities to confirm brain death.
Study Objective: To analyze if statins are effective in ameliorating perihematomal edema evolution thereby reducing mortality and improving functional outcomes following spontaneous intracerebral hemorrhage (ICH).
Annually, almost 5,000 extremely low birth weight (9 ounces to about 2 lbs) infants born in the US survive with severe bleeding in the brain (intraventricular hemorrhage); this devastating complication of prematurity is associated with many problems, including mental retardation, cerebral palsy, and learning disabilities, that result in profound individual and familial consequences. In addition, lifetime care costs for these severely affected infants born in a single year exceed $3 billion. The huge individual and societal costs underscore the need for developing care strategies that may limit severe bleeding in the brain of these tiny infants. The overall goal of our research is to evaluate disturbances of brain blood flow in these tiny infants in order to predict which of them are at highest risk and to develop better intensive care techniques that will limit severe brain injury. 1. Since most of these infants require ventilators (respirators) to survive, we will investigate how 2 different methods of ventilation affect brain injury. We believe that a new method of ventilation, allowing normal carbon dioxide levels, will normalize brain blood flow and lead to less bleeding in the brain. 2. We will also examine how treatment for low blood pressure in these infants may be associated with brain injury. We believe that most very premature infants with low blood pressure actually do worse if they are treated. We think that by allowing the infants to normalize blood pressure on their own will allow them to stabilize blood flow to the brain leading to less intraventricular hemorrhage. 3. In 10 premature infants with severe brain bleeding, we have developed a simple technique to identify intraventricular hemorrhage before it happens. Apparently, the heart rate of infants who eventually develop severe intraventricular hemorrhage is less variable than infants who do not develop this. We plan to test this method in a large group of infants, to be able to predict which infants are at highest risk of developing intraventricular hemorrhage and who could most benefit from interventions that would reduce disturbances of brain blood flow.
The highest risk for perinatal brain injury occurs among extremely premature infants who weigh less than 1250 grams at birth. Such perinatal brain injury is currently irreversible, associated with neurodevelopmental disability, and without adequate treatment modalities. Research in recent years suggest in both animal and human studies that erythropoietin (Epo) may have significant neuroprotective effects. Given the historical safe medical profile of Epo when used for anemia of prematurity but the likely need for a greater dosage regimen for activation of neuroprotective pathways against neonatal brain injury, we therefore propose this phase II study of high-dose Epo in very low birth weight infants for the prevention and/or attenuation of prematurity-related cerebral hemorrhagic-ischemic injury.
Administration of steroid to the mother in imminent preterm delivery is a known effective practice to decrease the risk of respiratory distress syndrome and intraventricular haemorrhage in preterm infants if given with a week of the preterm delivery. This randomized clinical trial is performed to test the possibility whether the repeat dose of steroid results in further reduction of these diseases in case the mother is in imminent preterm delivery more than a week after the first antenatal steroid treatment.
