Active clinical trials for "Hemorrhage"

Secondary brain ischaemia (SBI) usually develops after aneurysmal subarachnoid haemorrhage (SAH) and severe traumatic brain injury (TBI). The current management strategies are based on intracranial pressure-targeted therapy (ICP-targeted) with cerebral microdialysis monitoring (modified Lund concept) or cerebral perfusion pressure-targeted therapy (CPP-targeted). We present a randomised controlled study to compare the two management strategies. The hypotheses of the study were: SBI developed after aneurysmal SAH and severe TBI share the same crucial characteristics and any treatment applied will essentially treat the same underlying pathophysiology. ICP-targeted therapy with cerebral microdialysis monitoring according to the modified Lund concept is superior to CPP-targeted therapy in managing comatose patients with SBI after aneurysmal SAH and severe TBI. Sixty comatose operated patients with SBI following aneurysmal SAH and severe TBI were randomized into ICP-targeted therapy with cerebral microdialysis monitoring and CPP-targeted therapy groups. Mortality rates in both groups were calculated and biochemical signs of cerebral ischaemia were analysed using cerebral microdialysis. Outcome for cerebral microdialysis was measured as poor outcome (Glasgow Outcome Scale score 1, 2 and 3) or good outcome (Glasgow Outcome Scale score 4 and 5).

When patients suffer a subarachnoid hemorrhage (bleeding around the brain), they often develop hydrocephalus. This is an enlargement of the fluid-filled spaces (ventricles) in the brain. Standard-of-care treatment includes placing an external ventricular drain (EVD) to drain off fluid. Eventually the EVD is weaned with the goal of removing it. Occasionally a patient does not tolerate this and a permanent surgery needs to be done to internalize a shunt. Though this is done commonly and routinely throughout the world, there are no good studies to address how to optimally set the EVD level and how fast to wean it. Most set the EVD to a level of around 15 mmHg. The investigators hypothesize that setting the EVD lower (which will allow higher volume Cerebrospinal Fluid (CSF) drainage through the EVD) will improve perfusion at the level of the microcirculation in the brain, and result in improved neurologic outcomes.

The purpose of this study is to determine whether transjugular intrahepatic portosystemic shunt (TIPS) with 10-mm covered stent is associated with lower shunt dysfunction in comparing TIPS with 8-mm covered stent in cirrhotic patients with at least one episode of variceal bleeding.

Our primary goal is to study temporal trends in the incidence rate, causes, treatment, and outcome of stroke among a large biracial metropolitan population of 1,349,351, of whom 215,611 (15%) are black (2000 Census). Such data are critical for the planning, intervention, and evaluation of public health efforts to decrease the mortality and morbidity due to stroke in the United States. We have completed this goal for 1993-94, 1999, 2005, 2010 and 2015. We are in the process of collecting this data for 2020. In the 2020 study period we will also be ascertaining 3 year recurrence rates for all incident stroke events.

In unselected cirrhotic patients with bleeding esophageal varices to compare the influence on mortality rate, duration of life, quality of life, and economic costs of treatment of: Emergency portacaval shunt, and Emergency and long-term endoscopic sclerotherapy.

The study is single centered; prospective, parallel arm randomized controlled trial.The patients will be who presented to Institute of Liver & Biliary Sciences with esophageal variceal bleeding or develop esophageal bleeding during hospital stay. All patients will be managed with continuous non-invasive cardiac and hemodynamic monitoring including cardiac rhythm, pulse rate, blood pressure, and oxygen saturation. Hemoglobin (Hb) will checked every 6 h for the initial 48 h and then every 12 h till discharge. Likewise, serum creatinine will checked daily. Packed red blood cells will be transfused to maintain target Hb of ⩾8 g/dl. Patients will be started on IV Proton Pump Inhibitor, with bolus dose of terlipressin (2mg) followed by Endoscopic variceal ligation. All patients will received prophylactic antibiotics; antibiotics will be stopped if there will no other indication to continue. After confirmation of EVB (Esophageal Variceal Bleeding) and successful initial hemostasis with emergency EVBL (Endoscopic Variceal Band ligation), patients will be randomly assigned into Group -A (Bolus terlipressin at 2mg every 4hourly) and Group-B (Continuous infusion of terlipressin @ 4mg/24hour initially) therapy for esophageal varices . They will then undergo HVPG (Hepatic Venous Pressure Gradient) measurement at baseline, 12hours and 24hours. Patient in continuous group will titrate dose. accordingly to HVPG (Hepatic Venous Pressure Gradient) measurement at 12 and 24 hours. At 24 hours patient will be directed to receive either TIPS (Transjugular Intrahepatic Portosystemic Shunt) or will continue Terlipressin for 48 hours.

The risk of bleeding is important during transsphenoidal surgery. This study aims to find if the ventilation mode, controlled pressure and controlled volume, modifies the risk of bleeding.

It remains still unclear whether topical tranexamic acid has an added value besides the administration of intravenously tranexamic acid. We hypothesize that the addition of topical tranexamic acid, besides intravenous administration of tranexamic acid, results in a 25% reduction of post-operative blood loss after cardiac surgery. The aim of this study is to determine whether the application of topical tranexamic acid reduces the 12 hours postoperative blood loss by 25% in patient scheduled for cardiac surgery on cardiopulmonary bypass, whereby intravenous tranexamic acid is administrated. Just before sternal closure, 250 subjects receives pericardial lavage with 2 gr tranexamic acid in 200 ml normothermic saline solution (NaCl 0.9%), 250 subjects receives pericardial lavage with 200 ml normothermic saline solution without TA and 250 subjects (control group) receives no pericardial lavage. The main study parameter is 12 hours post-operative blood loss and is assessed by 12 hours post-operative chest tube production.

The primary purpose of this study is to get explorative information about IV high single dose infusion of iron isomaltoside 1000 compared to RBC transfusion in the treatment of severe PP-IDA evaluated as physical fatigue

Introduction: Gastrointestinal (GI) bleeding arising from malignant tumors is increasingly recognized as a result of oncological advances and improved detection methods, and stems from local vessel damage and tumor invasion with associated derangements in the hemostatic system(1, 2). Although conventional endoscopic hemostasis methods improve outcomes in UGIB due to peptic ulcers and other non-variceal benign bleeding lesions of the upper, and perhaps the lower GI tract, data on their use in hemorrhagic, upper or lower gastrointestinal neoplasms are scarce and associated with varying success in initial hemostasis and high rebleeding rates(3-7). Other recognized single or multimodality treatment approaches include radiation therapy, interventional angiography, and surgery. All exhibit disappointing rebleeding rates, and in the case of emergency surgery, high mortality(4, 8-11). Challenges associated with bleeding tumors include hematological derangements such as thrombocytopenia, disseminated intravascular coagulation, and neutropenia, as well as the endoscopic manipulation of friable, diffusely bleeding surfaces when attempting hemostasis(2, 12, 13). The recent advent of TC-325 (HemosprayTM) to Canada, Europe and Asia - referred henceforth as TC-325 - may provide a highly adapted novel endoscopic hemostatic therapeutic alternative for this refractory clinical entity, with promising uncontrolled observations having just been published by our group(13) and others(14). More robust controlled evaluative data are now needed. We propose to study the use of TC-325 in upper and lower malignant GI bleeding compared to contemporary standard of care, and more specifically seeks funding for a pilot study to inform a subsequent peer-review application for a larger, more definitive randomized clinical trial (RCT).
