Active clinical trials for "Hemorrhage"

This is a prospective cohort study investigating cardiac function and cardiac biomarkers in patients with acute Aneurysmal Subarachnoid Haemorrhage (aSAH). The aims of the study are to document the incidence of myocardial dysfunction,to find the predictive factors of myocardial dysfunction, describe heart rate variability and to assess the impact of all cardiac problems on morbidity and mortality.

Cardiac dysfunction can occur in aneurysmal subarachnoid haemorrhage and might impact patient's neurologic outcome Condition Aneurysmal subarachnoid haemorrhage World Neurosurgeon Federation Score ≥ III

The risk of bleeding after polypectomy of large colorectal polyps in patients taking aspirin is uncertain. This is a randomized, multi-center, placebo-controlled, double-blind study to compare the risk of significant bleeding after endoscopic polypectomy of large (>=10mm) colorectal polyps in patients continuing or discontinuing on daily acetylsalicylic acid (ASA) use. Eligible patients will be randomly assigned in a 1:1 ratio to a group taking 75mg daily ASA or placebo 7 days before and 14 days following polypectomy. The primary endpoint of the study is bleeding within 30 days from colorectal polypectomy. The secondary endpoints are composite cardiovascular events occurring between the date of randomization and 30 days after polypectomy.

To identify the underlying causes of macular haemorrhages in patients with high myopia In the eyes found to have macular haemorrhages secondary to choroidal neovascularisation, we hope to identify the risk factors for the development of choroidal neovascularisation in high myopia To study the functional outcome of these eyes as assessed by visual acuity To study the morphological outcome of these eyes by clinical assessment (and fundal photography) and fluorescein angiography

Despite experts' recommendations, the consumption of Fresh frozen plasma (FFP) is very heterogeneous among French cardiac surgery centers. This probably reflects heterogeneous practices that are not characterized and whose outcomes on morbidity and mortality are not documented. The principal objective of the study is to describe transfusional strategies of FFP in patients undergoing cardiac surgery. The other objectives are: to assess the conformity of FFP transfusion or lack of transfusion to current French authorities' recommendations, to describe the post-operative mortality and morbidity and to assess the prognostic role of FFP on mortality and morbidity. Prognostic analyses will take into account other prognostic factors of mortality and morbidity. 1500 patients undergoing cardiac surgery and presenting with a serious bleeding (or transfused with FFP without bleeding) will be included in the study.

This study evaluates the validity of an intravascular continuous glucose monitoring microdialysis probe, and compares the values to routinely inserted cerebral glucose microdialysis to evaluate the hypothesised relationship between intracranial and intravascular glucose levels.

Intrauterine contraceptive device is one of the most efficient and reversible methods of birth control with low cost and long duration of use However, in the first year after insertion, between 5 and 15% of women will have their Intrauterine contraceptive device removed because of irregular uterine bleeding which have been attributed to the effect of contact between the device and the endometrium and even the pressure on the uterine muscle . The disharmonious relationship between the Intrauterine contraceptive device and the uterus is the cause of most of the bleeding complaints, so bleeding is related to improper position rather than the contraceptive method itself which should be excluded before abandoning the Intrauterine contraceptive device for any other method of birth control

Coagulation dysfunction is frequent in septic patients and it is associated with an increase risk of mortality. During sepsis platelets number usually decreases and their function is reduced and this mechanism is sustained by an inflammatory induced coagulopathy. Some recent studies evaluated the possibility to use viscoelastic whole blood tests of the haemostasis, such as thromboelastography (TEG), which analyze all blood components and their interactions during clot formation and dissolution and might be useful for assessing bleeding risk in septic patients. Maximun amplitude (MA) is one of the variables obtained from TEG analysis and it expresses the strength of the clot and the efficacy of platelet function. A low level of MA describes a lower strength of the clot determined by a lower number or a reduced function of platelet. The aim of the present study is to evaluate whether a lower level of MA and a pattern of hypocoagulability might be associated with an increased risk of bleeding and need of transfusion in patients with sepsis. We want to conduct a prospective multicenter observational study, enrolling 100 consecutive adults patients with sepsis. We will exclude patients under 18 years old of age, chronic use of oral anticoagulant and anti platelet treatment, hematologic malignancy, congenital bleeding disorders, oral contraceptives, lack of consent. Primary end point To evaluate whether a lower level of MA might be associated with an increased risk of bleeding. Secondary end points: to evaluate whether a different level of MA correlates with the biomarker of the severity of sepsis such as presepsin, with the biomarker of the severity of infection and whether a pattern of hypocoagulability might be associated with a risk of mortality. All enrolled patients will undergo a blood sample at admission (T0), after 72 hours (T1) and after 7 days (T2) and all the following parameters will be measured: Platelet count, APTT, PT, INR, fibrinogen, procalcitonin and presepsin . Additionally, all viscoelastic parameters (reaction time (R), clot formation speed (K), angle (alpha) and maximum amplitude (MA)) will be performed at bedside, at T0, T1, T2: Outcome measurements: Intensive Care Unit Length of Stay and mortality at 28 days and at 90 days.

The purpose of this study is to evaluate the predictive value of serum adiponectin levels in aneurysmal subarachnoid hemorrhage patients.

The primary aim of the study is to investigate the relationships among FVIII, t-PA/PAI-1, MMP-9 levels, and intracranial hemorrhage after thrombolysis with alteplase using a combined analysis.
