Active clinical trials for "Hemorrhage"

Vasospasm is a common complication after rupture of intracranial aneurysms causing devastating neurologic deficits and death. Vasospasm has been directly associated with the amount of subarachnoid blood inside the basal cisterns. Prior literature has attempted to refine treatment of ruptured intracranial aneurysms but does not have clear guidelines on the optimal method to drain subarachnoid blood. Two methods, extraventricular drain (EVD) and lumbar drain (LD) have been compared retrospectively yet remain controversial as to which method is optimal in reducing subarachnoid blood and preventing vasospasm. This study would be a prospective randomized trial in which patients would be assigned to EVD or LD and observed to see if one method of intervention is associated with preventing clinical vasospasm, decreasing subarachnoid blood, shortening overall ICU stay, and reducing the need for a permanent ventriculoperitoneal shunt. The conclusions of this study may identify an optimal treatment modality to benefit all future patients with ruptured intracranial aneurysms.

This early phase I trial studies how well tranexamic acid works in reducing the loss of blood in patients with pelvic tumors undergoing hemipelvectomy surgery. Tranexamic acid decreases blood loss by stabilizing clots and preventing clot lysis in patients undergoing surgery.

The study purpose is to investigate the hypothesis that in adults with SAH, early neuromuscular electrical stimulation (NMES) and high protein supplementation (HPRO) will improve muscle mass, metabolic and inflammatory biomarker profiles, compared to SAH controls receiving standard of care interventions for nutrition and mobilization. The investigators will accomplish this by studying the effects of a high protein (HPRO) nutritional treatment as well as NMES intervention have upon muscle wasting and motor strength acutely after SAH. This will be addressed in a prospective trial of SAH patients receiving HRPO with NMES as compared to age and severity-matched SAH patients undergoing standard of care interventions for nutrition and mobilization. Additionally, the study will investigate the impact HPRO and NMES interventions have upon inflammatory cytokines and markers of energy balance. Results of this study will establish evidence for precision nutrition plus early exercise to mitigate the catabolic and inflammatory state produced by SAH to improve muscle, metabolic, and health recovery outcomes.

Aneurysmal subarachnoid hemorrhage (SAH) is a form of stroke in which secondary neurological deterioration is an important cause of mortality and morbidity. These secondary changes, so called delayed cerebral ischemia (DCI), are caused by lysis of erythrocytes which can react to form iron, an toxic substance to the brain. Iron chelators remove the excess of iron and are standard care in iron-overloaded patients. Deferoxamine (DFO) an chelator has not been evaluated in SAH patients. This study evaluates the safety of deferoxamine in SAH patients.

This study evaluates the safety and efficacy of 24-hour vs 72-hour octreotide infusion after variceal banding in cirrhotic patients with bleeding esophageal varices.

Upper gastrointestinal hemorrhage (UGIH) is common urgency condition.The estimate mortality rate about 7 percent from peptic ulcers disease(PUD). A proton pump inhibitors (PPIs) intravenous infusion are standard treatment for high risk ulcer bleeding. Vonoprazan,subclass of potassium-competitive acid blockers (P-CABs), have beneficial effects including rapid, long-lasting and strong acid suppression.The investigators design a randomized-controlled trial comparison between 72 hours of intravenous PPIs infusion and oral vonoprazan in high risk ulcer UGIH after achieve endoscopic hemostasis. Outcome measurement are re-bleeding rate in 30 days as primary and re-bleeding rate in 3 days, 30 days mortality, rate of angioembolisation, unit of blood transfusion, hospital cost and length of stay as secondary outcome.

This is a single-site, single-arm, open-label pilot study assessing the safety, feasibility, and efficacy of non-invasive vagus nerve stimulation (nVNS), gammaCore, for the acute treatment of aneurysmal subarachnoid hemorrhage (SAH) subjects in a neurocritical care setting. 25 patients will be enrolled, all treated with an active device. The primary efficacy outcomes are reduced aneurysm rupture rate, reduced seizure and seizure-spectrum activity, minimized hemorrhage grades, and increased survival.

Spontaneous intracerebral haemorrhage (sICH) is the deadliest stroke subtype yearly affecting over 6000 patients in the Netherlands. Treatment options are very limited. Inflammation plays a vital role in the development of sICH-related secondary brain injury (SBI). Within 4 hours after sICH onset, blood components and thrombin induce the release of cytokines and other inflammatory molecules, with subsequent microglial activation, blood brain barrier (BBB) damage and the formation of perihaematomal oedema (PHO). Among the released cytokines, interleukin 1 beta (IL-1β) has a pivotal role. Recombinant human interleukin-1 receptor antagonist (IL-1Ra, anakinra) effectively antagonizes IL-1β through competitive binding to the IL-1 receptor. Anakinra is available for treatment of rheumatoid arthritis, other inflammatory diseases and has been studied in acute sepsis. We hypothesize that anakinra safely reduces SBI after sICH, and that its effect is dose-dependent. Objective: To determine the effect of high-dose versus low-dose anakinra compared to standard medical management on oedema extension distance (OED) determined with MRI on day 7±1. Second, to study the safety profile of anakinra. Furthermore, to assess its effect on 1) serum inflammatory markers IL-1β, IL-6, hsCRP, neutrophil and total white blood cell counts at day 1, 3 and 7 compared to baseline; 2) DCE-MRI measurement of BBB transfer constant (Ktrans) on day 7±1, and; 3) to estimate an effect on functional outcome in patients with sICH. Study design: Multicentre, prospective, randomized, three-armed (1:1:1) trial with open label treatment and blinded end-point assessment (PROBE design) . Study population: 75 patients with supratentorial sICH admitted within 8 hours after symptom onset. Intervention: Patients will receive anakinra in either a high dose (loading dose 500mg i.v., followed by infusion with 2mg/kg/h over 3 days; n=25) or in a low dose (loading dose 100mg s.c.., followed by subcutaneous administration of 100mg twice a day for 3 days; n=25), started within 8 hours of symptom onset. The control group (n=25) will receive standard medical management. Main study parameters/endpoints: Primary objective is to test whether anakinra reduces subacute perihaematomal oedema after sICH, measured as OED on MRI at day 7±1.

This is a multicentre, prospective, randomised, double-blinded, group-sequential, parallel-group, adaptive design, phase 3 study to demonstrate the haemostatic efficacy and safety of four-factor prothrombin complex concentrate, OCTAPLEX, in patients with acute major bleeding on DOAC therapy with factor Xa inhibitor. Patients will be randomised 1:1 to either of two study groups: low-dose vs. high-dose OCTAPLEX.

An intertrochanteric (ITF) trochanteric fracture of the femur is an exclusively extra capsular fracture in which the fracture line extends from the greater trochanter to the lesser trochanter. Its incidence has increased significantly over the past decades and is expected to double in the next 25 years, with an important global economic impact . It affects women in the seventh and eighth decades of life, an age group older than femoral neck fractures. For this reason, the mortality of intertrochanteric fractures is twice that of the femoral neck. The treatment is surgical, in which the objective is the stable internal fixation and the patient's early ambulation. Functional outcomes and treatment mortality are related including factors perioperative anemia and blood loss.Even so, even with these precautions, blood loss in this surgical procedure appears to be greater than expected, with blood loss of the order of 2100ml. Blood loss management and the inherent risks of anemia can be circumvented with blood transfusion. However, blood transfusion is not without risks and complications, such as hypersensitivity and hemolytic reactions, cardiac overload, infectious diseases. Homologous transfusions are associated with prolonged hospital stay, increased costs and increased patient morbidity and mortality. So, alternatives have been used to avoid the use of blood such as saline solutions, use of erythropoietin and antifibrinolytic agents . Tranexamic acid (TXA) is a drug that interferes with fibrinolysis, in use for more than 50 years in surgery, particularly in cardiac surgery. Only recently, TXA has sparked interest in orthopedic surgeries. Studies have shown the effectiveness and safety of TXA at FIT, but presented different forms of administration (intravenous, topical, infiltrative) . Despite promising results to contain bleeding in elective orthopedic surgery and fractures, in daily practice, TXA is not very popular, especially in fractures, and has not been used routinely by all doctors. Studies have not been found in the literature about the topical use of TXA compared to intravenous use in FIT.
