Active clinical trials for "Hemorrhage"

Protective ventilation (association of a tidal volume < 8 ml/kg with a positive end expiratory pressure) is poorly used in severe brain-injured patients. Moreover, a systematic approach to extubation may decrease the rate of extubation failure and enhance outcomes of brain-injured patients. We hypothesized that medical education and implementation of an evidence-base care bundle associating protective ventilation and systemic approach to extubation can reduce the duration of mechanical ventilation in brain-injured patients.

To clarify whether amnesia after treatment of anterior communicating aneurysm (ACoA)is related to infarcts caused by occlusion or damage of the perforating artery of the ACoA, we used 3.0-T 3D high resolution MR imaging to identify and localize infarcts in patients with amnesia following treatment of ACoA aneurysm.

The purpose of this study is to compare the profile of microRNA in cerebrospinal fluid from patients suffering subarachnoid hemorrhage with and without delayed cerebral ischemia.

The purpose of the study is to investigate whether platelet indices from automated haematology equipment, whole blood impedance aggregometry and a standardized bleeding questionnaire predict bleeding in admitted patients with thrombocytopenia of various causes.

This study aims to characterize the diagnostic performance of immunological testing of occult gastrointestinal bleeding in stool in the population aged over 75 years with iron deficiency anemia. As secondary objectives, the study aims to: determine a threshold of positivity optimizing the immunoassay performance for the study population, in accordance with the probabilities of error (false positives, false negatives) and weights (defined by expert consensus) allocated to these errors. Assess the benefit of a double measure of bleeding (two stools) by immunoassay compared to a single measure.

The Cerebral Amyloid angiopathy (CAA) is the leading cause of cortical hemorrhage after 65 years. The presence of cerebral infarction is also reported anatomically in the AAC. MRI studies of these infarcts are rare. They are described as punctate, cortical silent. Frequency and pathophysiology is poorly understood. The investigators put the question of a link with hemorrhagic lesions of the AAC.

Major obstetric haemorrhage (MOH) remains a cause of significant maternal morbidity and mortality worldwide. By identifying women with a higher a priori risk of major haemorrhage during their pregnancy or early during postpartum haemorrhage extra measures to prevent MOH can be taken. In this study the investigators aim to identify haemostatic parameters that during the course of haemorrhage are responsible for the on-going towards major bleeding. By doing this, cut-off points can be defined for future interventions aiming to stop this bleeding process in an early stage. Traditional coagulation parameters are currently not useful for clinical decision making, because of long turn around times. Therefore the added value of available coagulation 'point of care' tests will be evaluated during obstetric haemorrhage.These Point-of-Care (POC) tests could lead to a goal-directed haemostatic therapy for obstetric haemorrhage. A cohort of 9.500 pregnant women will be followed during their pregnancy and delivery. From all women a bleeding score will be obtained during their pregnancy by means of a validated questionnaire. The predictive value of this bleeding score for the occurrence of major obstetric haemorrhage will be evaluated. If postpartum haemorrhage develops (blood loss) > 1000 cc, blood samples will be drawn for conventional haemostatic parameters and ROTEM profiles. The pathway between minor bleeding and major bleeding will be elucidated. Interchangeability and comparability of conventional haemostatic parameters and ROTEM profiles will also be evaluated. The overall goal of the investigators is becoming more able to predict major obstetric haemorrhage in an early stage of postpartum haemorrhage and define thresholds for goal-directed hemostatic therapies.

Dydrogesterone is a retroprogesterone with a molecular structure similar to natural progesterone. As a C-21 steroid, it has a high affinity for progesterone receptors, a low antigonadotropic activity and antiestrogenic activity, but almost no estrogenic or androgenic activity. Dydrogesterone (Duphaston©) is indicated for dysfunctional bleeding. In this study, women suffering from menorrhagia and who are treated with dydrogesterone will be observed for impact on QoL with the reduction in severity of bleeding.

Use of risk scoring systems in the assessment of patients presenting with upper gastrointestinal haemorrhage is increasing. Comparative studies have intended to identify the system of choice, but the majority of these are characterized by retrospective designs, small sample sizes, low rate of severe bleeding, or low mortality. The main aim of this study was to identify the optimal scoring system.

The goal of the present study is to investigate the clinical outcomes of patients with gastrointestinal bleeding originating from the small intestine following diagnostic investigation with single balloon enteroscopy. We hypothesize that single balloon enteroscopy can arrive at a diagnosis and provide therapeutics in a majority of patients with gastrointestinal bleeding originating in the small intestine.
