Active clinical trials for "Hemorrhage"

The aim of this study is to develop a coagulation algorithm based on Quantra POCT for the treatment of coagulopathic cardiac surgery patients.

To evaluate the performance of the Viz ICH VOLUME algorithm.

Some patients undergoing cardiac surgery develop excessive postoperative bleeding. Cardiopulmonary bypass causes platelet dysfunction. Several studies have documented the ability of desmopressin to reduce hemorrhage in a variety of congenital and acquired platelet disorders. In this study the investigators will investigate wether desmopressin reduces postoperative microvascular bleeding. The investigators will investigate wether desmopressin reduces platelet activation as measured by plasma concentration of neutrophil activating peptid 2 and by flow cytometry. The primary endpoint of the study will, however, be total postoperative bleeding and need for transfusions of blood components after surgery. The need for transfusions will be registered during the whole hospital stay. Patient with excessive postoperative bleeding (more than 250 ml for one hour, or more than 150ml for two hours during the first four hours) will be randomized into two groups and given either desmopressin or placebo (0,9% sodium chloride) as an intravenous infusion. Blood samples for plasma concentration measurements will be drawn before infusion of desmopressin/placebo, immediately after the infusion and 20 hours postoperatively. Postoperative bleeding will be registered for 16 hours. The need for any transfusions of blood products will be registered for the whole hospital stay.

Randomized controlled trial assessing the benefit of cesarean wound drainage in pregnant women at increased risk of hemorrhage. The pregnant women at increased risk of hemorrhage were randomised in two groups. In one group 2 wound drainages were placed during the cesarean section, in the other group none. Outcome measures were difference between preoperative and postoperative hemoglobin, postoperative fever, cumulative opiate dose adjusted to body weight, length of stay and operation time. It is postulated that the pregnant women with increased risk of hemorrhage do not profit from the routine placement of wound drainages. Trial with surgical intervention

We aim to investiagte whether very low dose self management of oral anticoagulation is superior to low dose oral anticoagulation in order to prevent bleeding events in patients undergoing mechanuical heart valve replacement.

The incidence of bleeding after metabolic surgery seems to increase. The administration of a drug (tranexamic acid) that can reduce bleeding could possibly also reduce bleeding after metabolic surgery. Objective: This study aims to determine whether administration of tranexamic acid before surgery can reduce postoperative bleeding in patients undergoing gastric bypass.

Comparison between Carbetocin and Oxytocin as prophylaxis against Primary Postpartum Hemorrhage.

Double lumen endotracheal tubes (DLT) are wildly used to maintain independent lung ventilation during thoracic surgery. Our aim is to assess whether the DLT bronchial cuff inflated or not is associated with tube displacement and bronchial mucosal injury while changing position.

Researchers sought to see how oxytocin versus, sublingual misoprostol affected estimated and measured blood loss during vaginal delivery in women who had blood loss >300 ml .

The purpose of this project is to quantify normal and abnormal skin blood flow regionally in different areas of the body(face, extremities, over burns and wounds) at baseline and over time in response to treatment or environmental changes, such as temperature, light and pressure.
