Filter by:The objective of this clinical trial is to determine whether rapid local ischemic postconditioning (RL-IPostC) is effective in preventing brain edema and safe in acute ischemic stroke (AIS) patients treated with mechanical thrombectomy. In this trial, researchers will block antegrade cerebral blood flow temporarily by the way of balloon inflation/deflation in AIS patients immediately after revascularization. It makes the ischemic reperfusion brain tissue have a capacity of adaptation through intermittent blood flow restoration. Researchers will evaluate the protective role and safety of different duration of balloon inflation/deflation. The optimal postconditioning intervention dose will be determined for further confirmative investigation.
The purpose of this study is to investigate the clinical improvement measured by the Glasgow Outcome Scale Extended (GOS-E) with ABX-101 compared with Placebo intramuscular injection in participants with moderate to severe TBI.
Purpose of the study：This study aimed to evaluate the clinical significance of serum SUR1, TRPM4 and MMP-9 in the diagnosis of cerebral edema in children with cerebral edema admitted to PICU by comparing them with CT results and perturbation coefficients, so as to provide biological indicators for clinical diagnosis of cerebral edema and provide targets for the treatment of cerebral edema in various diseases.
This phase I trial tests the safety, side effects, and best dose of dexamethasone when given with azeliragon in managing cerebral edema after surgery (post-resection) in patients with glioblastoma. Cerebral edema is a pathological increase in the water mass contained within the brain interstitial space. Dexamethasone is in a class of medications called corticosteroids. It is used to reduce inflammation and lower the body's immune response to help lessen the side effects of chemotherapy drugs. Azeliragon is an oral RAGE inhibitor. Blocking the RAGE pathway at the time of surgery (peri-operatively) may decrease cerebral edema. Giving dexamethasone with azeliragon may help control post-operative cerebral edema in decreasing doses of concurrently administered dexamethasone.
Spontaneous cerebral hemorrhage (SICH) is a hemorrhage caused by the rupture of a blood vessel within the brain parenchyma that is non-traumatic. Its rapid onset and dangerous condition seriously threaten human health; it accounts for about 15% of strokes and 50% of stroke-related mortality. Hunan Province is recognized as one of the high incidence areas of cerebral hemorrhage in the world; according to statistics, the direct economic loss caused by cerebral hemorrhage in Hunan Province is more than 1 billion yuan per year, which should be paid great attention. A 30-day follow-up study of large-volume cerebral hemorrhage (defined as supratentorial hemorrhage greater than 30 ml, infratentorial greater than 5 ml, and thalamus and cerebellum greater than 15 ml) found that the morbidity and mortality rate of ICH with hemorrhage of 30-60 ml was as high as 44-74%, while the morbidity and mortality rate of ICH with hemorrhage of <30 ml was 19% and that of >60 ml was 91%. According to studies, the occurrence of hematoma occupancy and malignant cerebral edema in large-volume cerebral hemorrhage can lead to secondary malignant intracranial pressure elevation and subsequent secondary brain injury, which are the main factors of high morbidity and mortality and poor prognosis in patients with large-volume cerebral hemorrhage. Clinical monitoring and management is the key to treatment, and despite aggressive surgical treatment and anti-brain edema therapy, a large number of patients progress to malignant brain edema disease, leading to poor outcomes. Therefore, this project intends to conduct a multicenter clinical trial of non-invasive monitoring of large volume cerebral hemorrhage on the curtain in the Hunan region to explore the impact of non-invasive brain edema monitoring management based on bioelectrical impedance technology on patient prognosis; and to explore early biomarkers of malignant brain edema through metabolomic analysis and the mechanism of malignant brain edema occurrence through multi-omic analysis to provide data support for the clinical treatment application of malignant brain edema.
Prospective observational study on patients undergoing decompressive craniotomy
In this prospective randomized controlled trial, investigator aim to evaluate the impact of early initiation of CRRT on outcomes in patients with acute liver failure with cerebral edema and hyperammonemia in improving cerebral edema and clinical outcomes. Investigator also aim to evaluate the effects of early initiation of CRRT on systemic hemodynamics (cardiac output and systemic vascular resistive index, extravascular lung water and lung permeability index), endothelial function and coagulation, microcirculation (as assessed by lactate clearance and central venous oxygen saturation), mitochondrial function. Patients with ALF who meet the inclusion and exclusion criteria. Group 1: CRRT initiation within the first 12 hours Group 2: CRRT would be initiated i) In patients with worsening hyperammonemia despite two sessions of plasma-exchange ii) Patients meeting renal indications (hyperkalemia, volume overload, oliguria or metabolic acidosis etc)
This study aims to evaluate brain injuries and brain edema with non-contact DCS-Speckle multi-parameter imager.
This study aims to investigate the inner mechanism during different dehydration therapies such as mannitol injection and hypertonic saline. The investigators used a self-made near infrared spectroscopy (NIRS) instrument to monitor the physiological changes noninvasively including oxyhemoglobin ([HbO2]), deoxy-hemoglobin ([Hb]), the derived change in blood volume ([tHb]) and water concentration on the forehead of brain edema patients.
Brain edema is the main reason for the disability and lethality in traumatic brain injury, which is the most difficult part of emergency rescue. Recently, there is no medical equipment to monitor the early brain edema in clinic. We have found that Electrical impedance tomography (EIT) can perform the real-time and bedside monitoring of brain electrical impedance after single-dose mannitol treatment, which may be a new strategy for the surveillance of brain edema. In this study, we would like to compare the application in traumatic brain edema between EIT and Noninvasive intracranial pressure (ICP) monitoring, including the progress of brain edema, the relationship between impedance and ICP, and the improvement for the patients' prognosis. EIT would probably be a new image strategy for the treatment of traumatic brain injury.
