Filter by:Intracerebral hemorrhage (ICH) results from the rupture of small vessels damaged by chronic hypertension, amyloid angiopathy or other disease. Currently, ICH has been a devastating type of stroke that lacking effective therapy. Remote ischemic conditioning (RIC), a systematically protective strategy, has been found to have neuroprotective effects by in patients with ischemic stroke. In addition, animal studies show that RIC is safe in ICH model and it could accelerate the absorption of hematoma. In a previous clinical study (RICH-1), RIC have been found to be safe and well-tolerated in patients with ICH. Therefore, the investigators plan to undertake this study to further evaluate the safety and efficacy of RIC in patients with ICH. The investigators hypothesize that treatment with RIC will accelerate the absorption of hematoma and improve patients' functional outcomes. Results of this study can potentially bring into account new means to improve the outcomes of ICH patients.
Comparative Study Between Oxytocin Versus Tranexamic Acid and Ethamsylate, Pre-operative Administration.
Prophylactic tranexamic acid has shown been shown to reduce maternal mortality from postpartum hemorrhage with no adverse effects, but has not been studied to reduce bleeding complications with dilation and evacuation (D&E). We propose a randomized, double-blinded, placebo-controlled pilot study to determine whether routine use of intravenous (IV) tranexamic acid will decrease the need for interventions to control bleeding at the time of D&E at 16 to 24 weeks gestation.
Nimodipine reduces the risk of poor outcome and delayed cerebral ischemia in patients suffering aneurysmal subarachnoid haemorrhage (SAH), but its mode of action is unknown. Its beneficial effect is assumed to be due its neuroprotective effects by reducing intracellular calcium and thereby cellular apoptosis, but higher concentrations might induce marked systemic hypotension, thereby inducing cerebral ischemia. Since several dosing regimes and routes of administration with inconclusive superiority exist and since the target site concentration of nimodipine - the unbound drug concentrations beyond the blood-brain barrier - is still not known, it is reasonable to measure nimodipine concentrations within the blood, cerebrospinal fluid (CSF) and interstitial brain tissue following oral, intra-venous and intra-arterial administration and correlate intra-arterial nimodipine administration to measures of cerebral metabolism and oxygenation. Therefore, the investigators propose to investigate in 30 patients suffering severe aneurysmal SAH and requiring cerebral microdialysis for cerebral neurochemical monitoring: - the ability of nimodipine to penetrate into the brain of neurointensive care patients by comparing exposure in brain, CSF and plasma, dependent on the route of administration (i.e. oral, intra-venous, and intra-arterial) and dosing intra-venously (0.5 - 2mg/h) - the impact of orally, intra-venously, and intra-arterially delivered nimodipine on cerebral metabolism, i.e. lactate/pyruvate ratio, pbtO2 and transcranial doppler flow velocities - the effect of oral and intra-venous nimodipine on systemic hemodynamic and cardiac parameters, using continuous Pulse Contour Cardiac Output (PiCCO) monitoring - the penetration properties of ethanol - as an excipient of nimodipine infusion - into the brain by comparing exposure in brain, CSF and plasma and quantifying the neuronal exposure to alcohol dependent on blood levels
To evaluate the safety and effectiveness of the Lava LES for the embolic treatment of arterial hemorrhage in the peripheral vasculature.
Rationale: The rapidly increasing number of elderly (≥ 65 years old) with traumatic brain injury (TBI) is accompanied by substantial medical and economic consequences. An intracranial hematoma, specifically an acute subdural hematoma (ASDH), is the most common injury in elderly with TBI. The surgical versus conservative treatment of this patient group remains an important clinical and moral dilemma, since it is in most cases unclear which treatment leads to a better outcome for the patient. Current guidelines are not based on high-quality evidence and compliance is low, allowing for large treatment variation in both Belgium and the Netherlands for patients with a traumatic ASDH. In addition, elderly are underrepresented in scientific TBI literature and are therefore not included in current guidelines or prognostic models, leading to major uncertainty in (neurosurgical) decision-making for this group. As participants in two large TBI research projects (CENTER-TBI, Net-QuRe), the investigators observe that the uncertainty regarding treatment of elderly with a traumatic ASDH will not be solved by the current ongoing studies. Therefore, they recognize the necessity of undertaking a prospective, randomized, multicenter trial on the (cost-)effectiveness of early surgical hematoma evacuation versus a conservative treatment in elderly with a traumatic ASDH. Objective: To compare the (cost-)effectiveness of early surgical hematoma evacuation versus a conservative treatment in elderly patients with a traumatic ASDH. Study design: A prospective, pragmatic, multicenter, randomized controlled trial (RCT). Study population: Patients ≥ 65 years with at first presentation a GCS ≥ 9 and a traumatic ASDH >10 mm or a traumatic ASDH <10 mm and a midline shift >5 mm, or a GCS < 9 with a traumatic ASDH <10 mm and a midline shift <5 mm without extracranial explanations for the comatose state, for whom clinical equipoise exists regarding the preferred treatment. Intervention: Patients are randomized to either early surgical hematoma evacuation (A) or conservative management on the ICU or the ward (B). In case of neurological deterioration during conservative management, delayed surgery can be performed. The exact neurosurgical technique will be left to the discretion of the surgeons. Main study parameters/endpoints: Functional outcome after 1 year, expressed by the rating on the Extended Glasgow Outcome Scale (GOS-E) Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Both treatment strategies are already used in current clinical practice as standard medical care. Therefore, there are no extra risks for patients participating in the study compared to patients outside the study. Study participation adds a minimal burden of three follow-up evaluations by visit in the first year (at 3, 6 and 12 months) and subsequent yearly evaluations by phone or postal until five years after the injury. Future elderly patients with a traumatic ASDH will benefit mostly from this study's results.
Phase IV multi-center, US-centric, open-label, safety study enrolling participants with Hemophilia A or B with inhibitors12 years of age and older, who are either on long term prophylactic treatment (e.g., emicizumab) at risk of experiencing a breakthrough bleeding event (BE), or who are not on prophylactic treatment who may need to control a BE.
Primary pontine hemorrhage (PPH) is not common but is the most catastrophic subtype of intracerebral hemorrhage, with acute mortality between 30% and 60%. For severe PPH, defined as Glasgow Coma score (GCS) <8 and hematoma volume≥5ml, the mortality rate is as high as 80-100%. Guidelines from the American Heart Association and European Stroke Organization do not make definite specifications. More than a century after Finkelnburg first explored the brainstem for hematoma, however, plenty of researches have shown surgery can save lives and improve the prognosis for selective patients and can be an effective and safe treatment. This study is proposed to validate the safety of surgical treatment in severe primary pontine hemorrhage.
Postpartum hemorrhage continues to be the leading cause of maternal morbidity and mortality worldwide. Successful management of postpartum hemorrhage requires not only administration of the right medicine, but also a rapid and coordinated response from a multi-professional team. A prerequisite for this is that the individuals are well trained, which the investigators believe can be improved by video debriefing of real-life events. The purpose of this study is to improve obstetric teams management of postpartum hemorrhage using video recordings of real-life events in post event debriefings. Cameras are placed in the ceiling of all delivery rooms to record obstetric teams' management of postpartum hemorrhage. Video recording requires informed consent from all participants. After an event, the team will review their own performance on video in a debriefing session to improve future performance.
This study is a two-stage, pivotal, prospective, non-randomized, multi-center, within patient comparison of the SENSE device and the standard diagnostic test, head CT scan in patients with a diagnosis of primary spontaneous ICH or traumatic intracranial bleeding for the detection and monitoring of intracranial hemorrhages.
