Filter by:The purpose of this study is to test the feasibility of a trial on induced hypertension to improve neurological outcome in patients with subarachnoid haemorrhage that developed the serious complication "delayed cerebral ischemia", and to assess whether induced hypertension results in improved cerebral blood flow (CBF) as measured by means of perfusion-CT.
The purpose of this study is to determine if certain seizure medications raise levels of cholesterol and other blood components which could increase the risk of heart attacks and strokes.
This is a prospective, randomized, double-blinded, placebo controlled pilot safety study that will enroll a total of twenty subjects. Subjects will be adults (30-75) who have sustained a SAH secondary to cerebral aneurysm rupture and who present with minimal neurological symptoms. All subjects will have a Hemoglobin less than or equal to 12 g/dL within 24 hours prior to study entry and undergo operative aneurismal clipping. Subjects will be randomized into two groups, ten subjects receiving the drug and ten subjects receiving the placebo. The subjects will receive three intravenous injections of study drug or placebo, once before undergoing operative aneurysmal clipping (study Day 1) and again for two additional days (study Day 2 and study Day 3). There are 3 phases to this trial: Screening Phase - patients will present with Subarachnoid hemorrhage (SAH) and prepped for surgery within 36 hours Treatment Phase - first pre-operative dose before surgery (Study Day 1), post-operative (Study Days 2 and 3) Follow-up Phase- Study Day 4 through discharge, 6-7 week follow-up Primary Objective: To determine the safety of administering intravenous doses of Procrit® once daily for three consecutive days to patients with aneurysmal SAH before and after vascular clipping by comparing the incidence of thrombotic events, hemoglobin and 6-7 week mortality between the Procrit® and placebo groups. Secondary Objectives: To determine if administration of Procrit® prior to aneurysm clipping reduces the incidence of vasospasm following a SAH event treated by vascular clipping. To determine if Procrit® administration prior to aneurysm clipping in patients with Aneurysmal SAH will improve neurological assessment scores in the post-SAH/post-clipping time period. To determine the feasibility of organizing a larger, randomized study to explore the neuroprotective effect of Procrit® in patients with Aneurysmal SubArachnoid Hemorrhage (SAH) when Procrit® is administered prior to surgical clipping of the aneurysm. It is hypothesized that Procrit will provide a significant level of neuroprotection in the brain after an SAH event as a result of reduced cell death, as well as a reduced amount of vasospasm activity and delayed cerebral ischemia which can occur as a result of SAH. These factors may contribute to improved neurological functioning scores when compared to the placebo treated patients.
The objective of this study is to determine whether acetaminophen (APAP), N-acetylcysteine (NAC), and APAP in combination with NAC will inhibit lipid peroxidation in aneurysmal subarachnoid hemorrhage (aSAH), utilizing F2-IsoPs as biomarkers for lipid peroxidation.
The purpose of this study is to investigate if brain oxygen levels, levels of a specific protein in the cerebrospinal fluid and blood (Cleaved-tau protein), and brain blood flow can predict spasm of brain blood vessels after bleeding in the brain from a ruptured aneurysm.
Critically ill patients are generally exposed to an increased oxidative stress, which is proportional to the severity of their condition. Endogenous antioxidant (AOX) defenses are depleted particularly in those patients with intense inflammatory response. The hypothesis tested is that early I:V: administration of a combination of AOX micronutrient supplements (Se, Zn, Vit C, Vit E, Vit B1) would improve clinical outcome in selected critically ill patients, by reinforcing the endogenous AOX defenses and reducing organ failure.
The purpose of this study is to test whether treatment with a drug called Simvastatin prevents and improves outcome in patients who have Subarachnoid bleeding. Simvastatin is currently approved for the treatment of high cholesterol levels.
Does the use of ultrasound facilitate a lumbar puncture by reducing the number of difficult and traumatic lumbar punctures?
The purpose of this study is to evaluate the tolerability and safety of 25 percent human albumin therapy in patients with subarachnoid hemorrhage.
