Filter by:The aim of this study is to determine if early angiographic embolization can forestall recurrent bleeding in selected high risk ulcers after their initial endoscopic control; to validate prospectively the investigators proposed in selecting high risk ulcers for recurrent bleeding in spite of maximal endoscopic control and profound acid suppression using high dose intravenous infusion of proton pump inhibitor; to characterize the nature of bleeding arteries in severely bleeding peptic ulcers and determine the efficacy of angiographic embolization in the prevention of recurrent bleeding and to establish safety profile of angiographic embolization as an early elective treatment to bleeding peptic ulcers.
Our primary objective is to compare two treatment options for prevention of seizures following a subarachnoid hemorrhage and determine if a short-course regimen of levetiracetam is as efficacious in the prevention of in-hospital seizures when compared to an extended course.
Current evidence regarding the efficacy and safety of perioperative administration of tranexamic acid for antifibrinolysis does not suffice to support its use in major spinal surgery. OBJECTIVES: To evaluate the effectiveness of tranexamic acid for decreasing transfusion requirements and bleeding in this patient population. To evaluate the safety of this antifibrinolytic agent in the intraoperative and mid-term postoperative period. METHODS: Multicenter, randomized, double-blind, placebo-controlled clinical trial with parallel groups. The main outcome measure is intraoperative and postoperative transfusion requirements; blood loss and safety will also be evaluated. Previous results in other types of surgery suggest that tranexamic acid reduces transfusion requirements and blood loss. Hence, the hypothesis of this study is that tranexamic acid will significantly reduce blood loss in comparison to a placebo in major spine surgery.
Peptic ulcer bleeding is a common disorder. Despite optimal endoscopic and medical treatment, there is a high risk of rebleeding and high mortality. In this study the investigators examine whether combined endoscopic haemostasis and angiographic embolization resolves in a better outcome than the traditional use of endoscopic haemostasis alone. The study is a randomised controlled trail.
In Patients with minor head injury measurement of protein S100 will be introduced to the emergency departement as another tool to rule out intracerebral bleeding.
Postpartum haemorrhage (PPH) remains the major cause of maternal mortality in France. The most efficient treatment of severe PPH is sulprostone which is associated with cardiac complications. The objective of this study was to assess the efficacy and the safety of intrarectal misoprostol for curative postpartum haemorrhage treatment. We conducted a multicenter double blind randomized placebo control trial between June 2004 and December 2007, among consenting women with postpartum haemorrhage and failure to oxytocin treatment. Our main criteria of judgement was quantification of blood loss and the use of sulprostone between the two groups using either misoprostol intrarectal tablets (5X200mg ) or placebo in similar opaque introducer.
This study examines early antiepileptic treatment with valproic acid for acute cerebral hemorrhage against a placebo group immediately post event to evaluate the outcome of these patients regarding seizures and neurological outcome.
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.
Previous studies showed that combination of endoscopic therapy with vasoconstrictor is better than either vasoconstrictor or endoscopic therapy alone in achieving the successful hemostatsis of acute variceal bleeding. The rationale of using vasoconstrictor is to enhance the efficacy of hemostasis by endoscopic therapy. Nowadays, endoscopic variceal ligation (EVL) has replaced endoscopic injection sclerotherapy (EIS) as the endoscopic treatment of choice in the arresting of acute esophageal variceal hemorrhage. EVL alone can achieve hemotasis up to 97% even in cases of active variceal hemorrhage. However, early rebleeding due to ligation-induced ulcer may be encountered. It appears that prevention of esophageal ulcers and bleeding by a proton pump inhibitor may be more logical than using a vasoconstrictor after cessation of bleeding by EVL.
In remote preconditioning, ischemia in one organ protects distant organs from ischemic insults. e.g. brief induced limb ischemia protects the brain from an otherwise more severe stroke. The objective of this study is to determine if remote ischemic preconditioning can be safely and effectively instituted in patients with subarachnoid hemorrhage, who are at high risk for developing disabling cerebral ischemia. The investigators will also preliminarily assess if there is evidence for neuroprotection. This will be a Phase 1b study. Additional objectives are: 1. to determine if remote ischemic preconditioning can be safely and effectively instituted in patients with subarachnoid hemorrhage, who are at high risk for developing disabling cerebral ischemia. 2. analogously to a dose-escalation study the investigators propose to study the safety and tolerability of increasing durations of limb ischemia until a target time of 10 minutes of limb ischemia has been reached.
