Active clinical trials for "Hemorrhage"

The objective of this non-interventional Post Authorisation Safety Surveillance (PASS) study is to observe the clinical safety performance of EVICEL when used as suture support for haemostasis in vascular surgery.

This study is performed to compare the efficacy and safety of EBL, propranolol, and EBL combined with propranolol in patients with medium or large varices.

Purpose of the present research project is to study a new in-vivo test for abnormal platelet function and to study the effect of certain drugs on clinical bleeding. This is a randomized clinical trial of a new in-vivo test of platelet function known as the bleeding volume test(BVT)which relies on an on-line measurement system. This trial will assess the sensitivity and specificity of the new BVT by studying the effects of aspirin which is known to affect platelet function in-vivo. This is not a clinical trial of drugs. This is a clinical trial of a novel in-vivo on-line laboratory test. The BVT measures the total volume of blood in the discrete blotches of blood on the blotter paper during the BT test and thus the BVT gleans valuable additional information from the bleeding time test (BTT)procedure. We hypothesize that the BV test will be a more accurate, specific and sensitive test for diagnosing platelet function abnormalities and for detecting a person's bleeding tendency compared to the BTT, and commercially available in-vitro platelet function tests.

This study will begin to define these critical determinants for patients undergoing procedures in the hybrid interventional cardiology/cardiac surgery suite. In future studies, the data obtained from this study will be used to prospectively stratify patients in terms of bleeding verses thrombotic risk to design studies to optimize anticoagulation and anti-platelet therapies in the hybrid setting.

The purpose of this study is to assess whether adherence to NVUGIB guidelines is improved with implementation of a national, tailored multifaceted intervention. Outcomes include adherence rates to two key endoscopic and pharmacological therapy guidelines together (primary), or adherence to these individually as well as to other recommendations (secondary). Patient outcomes and economic data are also assessed (tertiary).

The goal of this observational study is to develop and validate a predictive score of 1-year outcomes in subarachnoid hemorrhage (SAH) patients receiving aneurism coiling. Using our database filled up prospectively, the investigators plan to collect clinical, biological and radiological admission characteristics of coiled SAH cases and their 1-year Rankin outcome score during 5 years (2003-2007). The investigators plan to confirm our score in a validation cohort (from 2008 to 2009).

The rFVIIa (Novoseven) has been tested in traumatic hemorrhage but its efficiency has not been proven yet in this context. A national register has been set up in France identifying the patients which received rFVIIa. Those patients had persistent and active bleeding after severe trauma despite surgery and/or interventional radiology embolization. The aim of this present study is to report the first clinical results in those situations of patients treated with rFVIIa.

The overall aim of this project is to prospectively determine whether MRI can improve the conventional neuroradiological evaluation (CT with or without cerebral angiography) of patients with a spontaneous ICH or IVH. The study design will also allow us to identify the added benefit of specific MR sequences and repeat MRI in the chronic stage, thereby allowing us to prospectively determine their value in a consecutive series of patients. This information should have a major impact on the management of these patients by providing data on the diagnostic yield of routine MRI in patients presenting with a wide variety of causes for ICH or IVH. These data will help guide the diagnostic evaluation and the management of brain hemorrhage patients in the future.

The hypothesis of this study is that the antifibrinolytic drugs aprotinin and tranexamic acid equally influence bleeding tendency and transfusion requirement in patients undergoing first time cardiac procedures with a low risk of increased postoperative bleeding.Only patients undergoing first time CABG or first time aortic valve replacement are included in this study.
