Active clinical trials for "Hemorrhage"

The REACH trial is a prospective multicenter double-blind randomized placebo-controlled trial with blinded end-point adjudication. Participants are randomized (1:1) to receive either sodium aescinate or matching placebo (0.9% saline). The primary outcome is the absolute volume of PHE evaluated based on brain CT image on day 14 after ICH.

Objective: Mid-trimester preterm premature rupture of membranes (PPROM), defined as rupture of fetal mem-branes prior to 28 weeks' gestation (WG), complicates approximately 0.4-0.7% of all pregnancies and associated with very high neonatal mortality and morbidity. Antibiotics have limited success to prevent bacteremia, chorioamnionitis and fetal inflammation because of reduced placental transport. The repetitive amnioinfusion doesn't work because of immediately fluid lost after the intervention). The continuous amnioinfusion with Amnion Flush Solution through the perinatal port system in patients with classic PPROM prolonged the PPROM-to-delivery interval to 49 days in average by flush out of bacteria and inflammatory components from the amniotic cavity. Aim: This multicenter trial tests the effect of continuous amnioinfusion on the neonatal survival without major morbidities, like severe bronchopulmonary dysplasia, intraventricular hemorrhage, cystic periventricular leukomalacia and necrotizing enterocolitis. Design: randomized multicenter controlled trial; two-arm parallel design. Control group: 34 PPROM patients between 22/0 (20/0) -26/0 WG treating with antibiotics and corticosteroids in according to DGGG guide-lines. In interventional group (n=34) the standard PPROM therapy will be complemented by "Amnion -Flush" method with the amnioinfusion of artificial amniotic fluid (Amnion Flush Solution, Serumwerk AG, Germany, 2400 ml/d). Subjects: Patients with classic PPROM between 22/0-26/0 WG. Expected outcome:The investigators expect significant reduction of neonatal mortality and morbidity in the "Amnion-Flush" group.

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

Spontaneous intracerebral hemorrhage(SICH) is the most lethal and disabling stroke. Timely and accurate assessment of patient prognosis could facilitate clinical decision making and stratified management of patients and is important for improving patient clinical prognosis. However, current studies on the prediction of prognosis of patients with SICH are limited and only include a single variable, with less precise results and inconvenient clinical application, which may lead to delays in effective patient treatment. Our group's previous studies on SICH showed that hematoma heterogeneity and the degree of contrast extravasation within the hematoma are closely related to the clinical outcome of patients, but they are difficult to describe quantitatively based on imaging signs. Based on this, we propose to use radiomics to quantitatively extract hematoma features from NCCT and CTA images, combine them with patients' clinical information and laboratory tests, study their relationship with the prognosis of cerebral hemorrhage, and use artificial intelligence to establish a rapid and accurate prognostic prediction model for patients with SICH, which is of great significance to guide clinical individualized treatment.

In this prospective study, the investigators aim to investigate the effect of the following three factors on the development of vasospasm and patient outcome: (1.) the role of anemia; (2.) the role of plasma fibrinolytic activity; (3.) the role of vitamin D. The investigators include patients admitted to the Neurosurgical Intensive Care Unit of the Clinical Center of the University of Debrecen with the diagnosis of subarachnoid hemorrhage (SAH). Patients are treated according to international guidelines. As part of the study protocol the following investigations are performed: • Hemoglobin level measurement: on the day of admission and day 3-4-7 and 14 after hemorrhage •Modified clot lysis assay (mCLA): on the day of admission and day 7 after hemorrhage •25-hydroxy vitamin-D level measurement: on the day of admission •Transcranial color-coded duplex sonography (detecting vasospasm): on daily basis. •30 day follow-up: mortality, Glasgow Outcome Scale (GOS), Karnofsky score, Barthel score •90 day follow-up: mortality, Glasgow Outcome Scale , Karnofsky score, Barthel score. Laboratory test results are correlated with (a) the development of vasospasm; (b) with 30 and 90 day outcome. Perspectives of the planned study: Considering the currently available therapeutic range for patients with SAH, results of the present study may provide a basis for designing further randomized, prospective trials to investigate the effect of treating anemia, anticoagulation and vitamin-D supplementation.

Up to this day, little is known whether the extent of brain damage in patients with SAH correlates with the degree neurogenic myocardial injury and neurogenic lung injury. This is a prospective observational study designed to asses relationship between catecholamine surge and development of myocardial and lung injury in subarachnoid haemorrhage patients.

Acute bleeding is one of the most frequent intraoperative adverse events and is burdened with a significant morbidity and mortality rate. The only available treatment for severe exsanguination is homologous transfusion, but this is itself complicated by side effects. Nevertheless, systems exist allowing the recovery, treatment and intraoperative reinjection of lost blood, thus limiting transfusions.

This registry will capture real-world clinical use patterns and associated clinical outcomes with the use of CytoSorb for the removal of antithrombotic agents.

This is a three-year pre- and post- interventional study to assess the effectiveness of collaborative quality improvement interventions on reducing mortality and severe intracranial hemorrhage (ICH) for neonates receiving extracorporeal life support (ECLS) in China.

The objective of this study is to evaluate the hemostatic capacity of two types of collagen hemostatic sponges in nail surgery. It is a randomized triple-blind clinical trial with two experimental groups (medium porosity collagen and high porosity collagen) and control group ( non collagen).
