Filter by:In this study we will investigate whether tranexamic acid given as an intravenous bolus injection before start of surgery, followed by a continuous infusion during surgery reduces, perioperative hemostatic activation, and postoperative bleeding and the need for transfusions of blood components in elderly patients undergoing combined aortic valve replacement and coronary artery bypass surgery. Tranexamic acid will be compared with placebo (0.9% sodium chloride) in a randomized and double-blind study design. The study hypothesis is that tranexamic acid will reduce hemostatic activation and postoperative hemorrhage and the need for blood component transfusions in this group of patients.
CRASH 2 is a large pragmatic randomised placebo controlled trial of the effects of the early administration of the antifibrinolytic agent tranexamic acid on death, vascular events and transfusion requirements. Adults with trauma who are within 8 hours of injury and have either significant haemorrhage, or who are considered to be at risk of significant haemorrhage, are eligible if the responsible doctor is for any reason substantially uncertain whether or not to use an antifibrinolytic agent. Numbered drug or placebo packs will be available in each participating emergency department. Randomisation will involve calling a 24-hour freecall randomisation service. The call should last only a minute or two and at the end of it the randomisation service will specify which numbered treatment pack to use. For hospitals where telephone randomisation is not feasible, randomisation will be by taking the next consecutively numbered treatment pack. No extra tests are required but a short form must be completed one month later or on discharge or on death (whichever occurs first).
High intravenous dosage of Proton Pump Inhibitors is not better than standard dosage in bleeding peptic ulcers successfully treated by endoscopic therapy
The aim of this clinical research project is to evaluate the use of the recombinant human activated factor VII (rhFVIIa), given as a salvage therapy, in women with a dramatic postpartum hemorrhage still ongoing after all the currently available medical and surgical treatments. We are going to compare its early use, before elective surgery or arterial embolization, to its late use, after embolization or surgery, before salvage hysterectomy.
Late vitreous hemorrhage in postvitrectomized diabetic eyes may be due to fibrovascular tuft formation in sclerotomy sites. Cryotherapy of sclerotomy sites may prevent bleeding by regressing the fibrovascular tuft. This study will detect the safety and efficacy of cryotherapy of sclerotomy sites for prevention of late vitreous hemorrhage in vitrectomized diabetic eyes.
The purpose of this study is to determine whether 24 hours of Terlipressin is as effective as 72 hours of Terlipressin in preventing re-bleed once esophageal variceal bleed has been controlled with endoscopic therapy (variceal band ligation or sclerotherapy) in low to moderate risk variceal bleed patients and hence can save cost and may decrease length of hospital stay especially in the I.C.U or high dependency units.
The purpose of this study is to compare the effect of Esomeparzole with Placebo in the Prevention of Recurrent Ulcer Bleeding in Patients Receiving a COX-2 Inhibitor
The purpose of this study is to determine whether rosuvastatin is effective in the management of acute phase of intracerebral hemorrhage and if it impact outcome by NIHSS.
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.
To investigate if self-inserted vaginal misoprostol prior to outpatient hysteroscopy will lead to satisfactory cervical ripening, compared to placebo.
