Active clinical trials for "Hemorrhage"

This is a single-blinded, randomized clinical trial to determine if the Layperson Audiovisual Assist tourniquet's (LAVA TQ) ability to occlude arterial blood flow is non-inferior to that of the Combat Application Tourniquet (CAT).

Primary arthroplasties are frequent interventions that can present hemorrhagic complications: postoperative hematoma, deglobulization justifying monitoring blood tests and blood transfusion if necessary. The attitude regarding the drainage of the surgical site supposed to limit these events differs from one surgeon to another, even in the same team. Its use is common practice; for some, systematic. For others, depending on intraoperative findings or the patient's condition. For others, the drain is never laid. Faced with the divergence of data from the literature on the benefit of the placement of a drain for intra and postoperative bleeding in knee arthroplasty, the lack of randomized prospective studies on large series of patients, and in a desire to homogenization and standardization of the operating procedure of our surgeons, investigators decided to conduct this prospective interventional, comparative and randomized study.

General anesthetic induced neurotoxicity has received considerable attention in the past decade from various pre-clinical studies in rodents and non-human primates. Which demonstrated that exposure to general anesthetic agents for a longer duration can induce neuronal cell death that can lead to adverse neurodevelopmental outcomes. The neuroapoptosis and impairment of neurodevelopmental processes has been postulated as the underlying mechanism, but the molecular mechanisms was not completely understood. Various hypothesis has been proposed they are- Antagonistic effect on N-methyl-D-aspartate receptors and agonistic effect on gamma-aminobutyric acid type A receptors; mitochondrial perturbations and activation of reactive oxygen species and dysregulation of intracellular calcium homeostasis. They trigger neuroapoptosis and cell death through the activation of caspases.3 Caspases, a group of cysteine proteases, plays an important role in regulation and execution of apoptosis. Caspase-3 is most important since it is activated by many cell death signals and cleaves a variety of important cellular proteins.4 Various anesthetic agents like isoflurane, halothane, sevoflurane, nitrous oxide and propofol causes neurotoxicity by activation of caspase-3. Which has been proven from various animal studies western blot analysis, immunohistochemical analysis and flow cytometric analysis.3, 5-9 Though it is documented that exposure to general anesthetics causes neurotoxicity during active brain growth in animals, there is no evidence of such effects in adult humans.10 and it is difficult to separate the effects of anesthetics from surgical impact and other factors associated with diseases.11 The patients with aneurysmal subarachnoid hemorrhage (SAH) have variable degree of neurological insults and it is possible, based on the evidence from animal models that administration of general anesthetics could add to the neuronal insults.

It is a multicenter randomized, double-blind and placebo-controlled trial. Totally 6500 women to delivery by cesarean section will be recruited in this study. In addition to routinely oxytocin, the women in study group will receive TXA 1 g in 2 minutes after they delivered their babies, and those in control group will receive placebo. The incidence of postpartum hemorrhage, the amount of bleeding, as well as the side effects will be observed.

The bio-markers substudy of EsICH is designed to recruit patients with acute (first 8h) spontaneous intracerebral hemorrhage and assess a series of biological parameters (CBC, glucose, cholesterol, LDL cholesterol, triglycerides) and point-of-care bio-markers (cTnI, hsCRP, D-Dimer) in order to predict the functional outcome of these patients and to determine their input for early risk stratification and prognosis.

The purpose of the study is to evaluate the efficacy of Rifaximin in the treatment of cirrhotic gastroesophageal variceal bleeding.

To date there are no available data on the utility of the endoscopic mucosal resection (EMR) defect in stratifying the risk of immediate or delayed adverse outcomes, particularly clinically significant post EMR bleeding (CSPEB). The investigators aimed to analyse the data to determine if any of these EMR defect features allow us to estimate the risk of CSPEB. This will help endoscopists to identify defects with a high risk of adverse outcomes and may translate into improved patient outcomes.

Intracerebral hemorrhage [ICH] is the most feared sub-type of stroke, associated with a high mortality rate up to 50% and thus leaving large proportions of patients in functionally dependent states. In recent years randomized trials have failed to provide an effective intervention to improve functional outcome in ICH. Therefore, evidence regarding acute therapeutic interventions as well as secondary treatment approaches is still limited. The present monocentric longitudinal study on spontaneous ICH patients is based on a prospective institutional stroke registry including all hemorrhagic stroke patients treated at a German University Hospital, Department of Neurology, over a 10 year time frame (2006-2015). The main aim of this investigation, besides analyses of epidemiological aspects, will be (i) to identify possible treatment targets influencing functional outcome, and (ii) to evaluate existing therapeutic strategies in ICH care.

HeadSense (HS)-1000 device, a proprietary non-invasive brain monitor, is expected to safely and accurately monitor physiological signs of the brain with minimal discomfort to patients, providing information about normal or abnormal brain-related conditions and providing decision-making support for physicians. The investigators hypothesize that the HS-1000 is capable of detecting vasospasm using the raw acoustic data derived from the noninvasive procedure.

The aim of this study is to compare the effect of low dose of Tranexamic acid (1gm) and Ethamsylate (1gm) after prophylactic oxytocin administration versus placebo with prophylactic oxytocin given in the 2 minutes after child delivery in patient undergoing LSCS at high risk for post partum hemorrhage
