Active clinical trials for "Hemorrhage"

The aim of this study is to evaluate the efficacy of tranexamic acid in reducing blood loss during and after elective C.S. The Research Question Is Tranexamic acid effective in reducing blood loss during and after elective Caesarean section? The Research Hypothesis The TXA could be able to reduce blood loss during and after elective Caesarean section. The null hypothesis will therefore state that: There will be no difference between TXA and placebo in reducing blood loss during and after elective Caesarean section.

Protamine is used after Cardiopulmonary Bypass (CPB) to reverse the anticoagulant effects of heparin and restore coagulation. Convincing evidence from in-vitro and in-vivo studies suggest that an overdose of protamine has anticoagulant effects which might lead to bleeding complications. Heparin levels usually decrease during cardiac surgery with CPB. Therefore, a protamine regimen based on the initial heparin dose before CPB might lead to overdose of protamine. In contrast, a protamine regimen based on the actual heparin concentration may avoid this condition. The investigators compare both regimens of protamine dosing in patients undergoing complex surgery with CPB and assess its effect on the amount of protamine given, markers of the coagulation system, utilization of blood products and perioperative blood loss.

Non-invasive monitoring to measure changes in blood volume.

The study aims at comparing the roles of carbetocin and oxytocin in the prevention of atonic PPH in women undergoing CS for placenta previa. 200 women will be randomly divided into 2 equal groups using computer generated random numbers, Group 1 will receive Carbetocin 100 µgm (Pabal® Ferring, UK) and group 2 will receive oxytocin 5IU (Syntocinon®, Novartis, Switzerland).

This study is determining the clinical outcomes, based on neurological testing, for the parafascicular minimally invasive clot evacuation technique. We will collect data from the time of surgery up until 90 days post procedure. We will also be looking at financial data as well. H(0): there is no economic benefit to the system with early surgical intervention for ICH Alternative Hypothesis:H(1) Assuming clinical equipoise, i.e., no benefit in clinical outcome with early surgical intervention (null hypotheses) H(0) is correct), the ability to accelerate the patients care from the entry point to the exit point will result in a significant economic advantage to the system through cost reduction.

The purpose of this study is to test the safety and effectiveness of a whole own (autologous) umbilical cord blood transfusion in the first 5 days after birth if the baby is born premature <34 weeks and developed anemia of prematurity.

The 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors, known as statins, have recently been demonstrated to improve endothelial function. Additionally, numerous studies have shown statins as having antiinflammatory and cell-signaling effects together with a selective up-regulation of the eNOS activity. These findings are of potential benefit for the prevention of cerebral vasospasm after a aneurysmal subarachnoid hemorrhage. Indeed, one of the possible mechanisms for this vasospasm is the eNOS depletion or even increase of eNOS expression after the hemorrhage. The purpose of this study is to observe the immediate effect of statins after aneurysmal subarachnoid hemorrhage (aSAH) in cerebral vasospasm and outcome at one year.

This study is being conducted to collect data on the management of major bleeding events occurring in patients with atrial fibrillation taking dabigatran etexilate.

The purpose of this study is to examine the impact of cranioplasty on cerebral hemodynamic and blood flow as prognostic factor in patients receiving decompressive craniectomy for Head injuries, Subarachnoid haemorrhage, intra-cerebral haemorrhage, cerebral dural sinus thrombosis, malignant middle cerebral artery stroke.

Even if most patients in palliative care units presented with well-recognized risks factors of venous thromboembolism (VTE) (eg: active cancer, bed rest, previous history of venous thrombosis), the incidence of VTE in palliative setting is unknown. By consequence, the efficacy and safety of antithrombotic prophylaxis in such a population is not established. Indeed, patients admitted in palliative care units were not included in trials evaluating the potential effect of antithrombotic drugs in regard to their poor prognosis at short term. In addition, the main role of prophylaxis is to prevent sudden death from pulmonary emboli and is thus a life prolonging therapy which is viewed as counterintuitive to palliative care philosophy and inappropriate on grounds of futility. Nevertheless, the current use of Low Molecular Weight Heparin in palliative care units seems to increase particularly in patients with advanced malignancy. The identification of high hemorrhagic risks in palliative care patients could help the decision of antithrombotic prophylaxis initiation. For this, the investigators conducted a multicenter prospective longitudinal study.
