Filter by:The investigators will conduct a proof-of-concept study to provide preliminary evidence of efficacy of physical exercise dose on ambulatory function in adults undergoing sub-acute stroke rehabilitation.
Study objectives: The main objective of this study is to determine the feasibility of implementing measures in the intensive care unit (ICU), based on a physiological algorithm, to reverse decreases in cerebral oxygen saturation using, near-infrared spectroscopy (NIRS). Methods: Randomization of 50 patients is balanced by experimental group; control and intervention, with an allocation sequence based on a block size of ten, generated with a computer random number generator. In the intervention group ICU Staff will use NIRS to follow a physiologically guided strategy to maintain regional oxygen saturation (rSO2) within 90% of baseline values. In the control group ICU Staff will provide standard of care without the use of NIRS.
Using placebo as control, The purpose of this study is to evaluate the efficacy and safety of methanesulfonic acid cinepazide injection to relieve disabled degree of acute cerebral infarction patients, and explore the best safe and effective dose as well as dose method.
This randomized trial tests the effect of early blood pressure reduction on major disability and death among patients with acute ischemic stroke in china.
The purpose of this study is to determine if systemic cooling to a target temperature of 34 to 35°C, started within 6 hours of symptom onset and maintained for 12 hours, improves functional outcome at 3 months in patients with acute ischaemic stroke.
This is a randomized, placebo-controlled, single-center clinical trial investigating the effectiveness of administrating intravenous Cerebrolysin™ (EVER NEURO Pharma, Austria), a preparation of low-molecular weight neurotrophic peptides and free amino acids, in improving the functional outcome of patients suffering from aneurysmal subarachnoid haemorrhage ( SAH). Cerebrolysin™ is a porcine-derived intravenous formulation composed of multiple lipid-soluble active agents that can cross the blood-brain barrier. It is a registered medication in several countries indicated for stroke and Alzheimer's disease. It contains several low molecular weight neuropeptides and free amino acids that possess neuroprotective and neurotrophic properties. It has been proven to arrest or mitigate several crucial steps along the ischemic cascade in preclinical studies. Cerebrolysin™ has been extensively investigated in patients suffering from Alzheimer's disease, brain trauma and ischemic stroke with promising clinical results. It's use in SAH patients has never been investigated and it is believed that it may play a role in improving clinical outcomes. Consecutive patients aged 18 to 70 years-old diagnosed to have spontaneous subarachnoid hemorrhage secondary to a ruptured intracranial aneurysm will be randomly allocated into one of two study arms: (1) to receive intravenous Cerebrolysin™ in additional to standard of care (intervention group) or (2) to receive usual standard of care alone (control group). Permuted-block randomization will be carried out once the eligibility criteria have been fulfilled using a computer system with an allocation list of random order. Instructions on study arm allocation will be contained in sealed envelopes labeled with sequential study numbers. Patients presenting beyond 96 hours after onset of symptoms or if recruitment and randomization cannot be performed within this time period will be excluded. The reason being that post-SAH arterial vasospasm and delayed cerebral ischemia usually occurs four days after aneurysm rupture and lasts for two weeks i.e. 14 days. Should this complication arise before Cerebrolysin™ is administered there would be significant confounding of trial outcome measures . The timing of intervention is in keeping with several landmark clinical studies that have dealt with neuroprotective agents in subarachnoid hemorrhage. Patients in the intervention group will receive in a daily total dose of 30ml of intravenous Cerebrolysin™. The study medication will be administered in three separate 10ml doses (every eight hours) diluted in 0.9% NaCl saline to a total volume of 100 ml as an intravenous infusion over a time period of 15 minutes. An identical amount of 0.9% sodium chloride (NaCl) saline (100 ml) will be used as placebo for patients allocated to the control study group. The total duration of study medication or placebo administration will be 14 days. Cerebrolysin™ is a clear yellow solution. Since it is susceptible to photo-degeneration the preparation after dilution with 0.9% NaCl saline requires masking with a opaque plastic wrap as well as special photo-protective infusion sets. The dilution of the Cerebrolysin™ solution will be performed by ward nursing staff . Subjects in both trial groups will receive identically wrapped preparations so that both the functional outcomes assessor and patient are blind to the study arm allocation. In addition to general demographic data, clinical data including the admission Glasgow Coma Score, severity grading of SAH, hospital stay as well as the extended Glasgow Outcome Score and modified Rankin Score upon discharge, at three months and six months will be prospectively collected. The functional outcomes assessor will be an occupational therapist unaware of the subject's trial group allocation. Hypothesis: compared to patients receiving standard care for the management of aneurysmal subarachnoid hemorrhage alone (control), the additional administration of intravenous Cerebrolysin™ (intervention) within the acute phase of stroke is safe and improves functional outcome at six months after stroke.
Acute ischemic stroke affects roughly 1 in 50,000 children every year and is one of the top ten causes of death in children. Currently, caregivers lay the affected child flat in hopes of increasing blood flow to the brain and reducing the volume of the brain which is damaged. However, there are currently no techniques to measure brain blood flow at the child's bedside and indicate if this treatment is effective. We will probe brain blood volume, oxygen saturation, and flow with red light to determine the efficacy of this intervention.
This is a Post Marketing Observational Study of cilostazol (Pletaal® SR capsule). As this study is observational in nature to collect the safety data after administrating the Pletaal SR capsule, from baseline to 16 weeks.
This is a 20-week study consisting of a 12-week multicenter, randomized,double-blind adaptive study to compare efficacy and safety of Qizhitongluo Capsule,Naoxintong Capsule and placebo in the recovery phase of ischemic stroke with qi deficiency and blood stasis syndrome, and a 8-week post-treatment safety follow-up.After 312 patients complete 12 weeks of treatment there will be an interim analysis.
The purpose of this study is to determine whether reducing a patients body temperature (mild hypothermia of 33 degrees Centigrade) will significantly reduce the risk of brain injury (notably reperfusion injury and hemorrhagic conversion) in patients that have suffered a significant interruption of blood flow to an area of brain (occlusion of large proximal cerebral artery) and have undergone successful removal of that interruption (revascularization).This will be achieved by comparing patients that have undergone hypothermia to those that have not.
