Active clinical trials for "Hemorrhage"

The investigators hypothesize that octreotide LAR (Long Acting Release) safely decreases GI bleeding in patients with a left ventricular assist device (LVAD). Patients undergoing implantation of non-pulsatile, continuous-flow LVAD have a higher incidence of gastrointestinal bleeding. This is a significantly associated morbidity and can threaten a patient's life as well as their ability to undergo eventual heart transplantation secondary to both general health/strength and the potential development of antibodies to blood products that would make future transfusions and transplantations more difficult. If this research finds that use of octreotide LAR can decrease the incidence of gastrointestinal bleeding in this patient population, it will revolutionize the manner in which these patients are managed. The finding of reduced GI bleeding would allow the patient to have less exposure to blood products, reduce hospitalizations, and ensure that subsequent transplant planning not be delayed. This would not only be of great benefit to the patient, but would significantly decrease health-care costs through preventive measures. The goal of this project is to study whether the regular administration of monthly octreotide LAR is safe and if it will decrease the incidence of gastrointestinal bleeding in patients undergoing implantation of non-pulsatile, continuous flow left ventricular assist devices (LVAD).

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: 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. 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.

The intention of the study is to investigate whether drainage of cerebral spinal fluid via a lumbar route ("Tuohy-drain") will improve outcome after intracranial aneurysmal subarachnoid hemorrhage (SAH).

The study shall evaluate the volume effect and safety of 6 % hydroxyethyl starch 130/0.4 for restoration and maintenance of hemodynamics during the investigational period in patients undergoing major elective surgery. Up to 50 mL 6% hydroxyethyl starch/kg body weight will be administered from start of surgery until two hours after end of surgery. The study hypothesis is that 6 % hydroxyethyl starch 130/0.4 will have a reliable volume effect and can be safely administered up to the dose limit.

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.

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.

The LAST study is a Norwegian multi site randomised controlled trial that intends to assess the effect of a long term follow up program after stroke. The program consists of a coordinating physiotherapist who will encourage and motivate included patients to perform at least 60 minutes of intensive motor training every week and 30 minutes of physical activity every day for 18 months after inclusion. The primary hypothesis is that patients receiving a long term follow up program after stroke will have better motor function at end of follow up than patients receiving standard care. A total of 390 home dwelling stroke patients living in the municipality of Trondheim, Asker and Bærum will be included at the out-patient clinic at St. Olavs Hospital or Bærum Hospital three months after their stroke. Included patients will be randomised to an intervention group receiving the long term follow up program or to a control group receiving standard care. Motor function, mental health and physical functioning in daily life will be assessed at inclusion and 18 months later. The LAST study is funded by the Norwegian Research Council, the Norwegian University of Science and Technology and the Central Norway Regional Health Authority and will conclude at the end of 2015.

Post-partum hemorrhage (PPH) is a major cause of maternal death worldwide. Oxytocin is the most common uterotonic drug used to prevent and treat PPH in North America, however, there are some limitations to its use. Oxytocin has a very short duration of action, which requires a continuous infusion to achieve sustained uterotonic activity. The Society of Obstetricians and Gynecologists of Canada (SOGC) has recently recommended a single 100mcg dose of carbetocin at elective Cesarean delivery to promote uterine contraction and prevent post partum hemorrhage (PPH), in lieu of the more traditional oxytocin regimens. Carbetocin lasts 4 to 7 times longer than oxytocin, with a similar side effect profile and apparent greater efficacy rate. However, a dose response to determine the minimum effective dose of carbetocin has not yet been published. The investigators hypothesize that the minimum effective dose (ED90) is above 20mcgs and below 80mcgs in women undergoing elective Cesarean delivery.

The purpose of this study is to confirm the superiority of Fibrocaps plus gelatin sponge, as compared to gelatin sponge alone, for achieving hemostasis. The investigational products were used in participants with mild to moderate surgical bleeding during spine, liver, vascular or soft tissue surgery, when control of mild to moderate bleeding by standard surgical techniques is ineffective and/or impractical.

Patients with comorbidities have an increased risk of ulcer re-bleeding, especially within the 14 days after first bleeding event. Three-day high dose esomeprazole infusion can prevent peptic ulcer rebleeding after endoscopic therapy. However, the optimal dose of oral esomeprazole is uncertain, especially for high risky patients. This study is to test whether a double dose of oral esomprazole could reduce peptic ulcer rebleeding for patients with Rockall score ≥ 6. Additionally, the second aim of this prospective study was to identify the selection criteria to predict poor fading and residual major stigmata of recent hemorrhage (SRH) or early recurrent bleeding after successful endoscopic hemostasis and high-dose PPI infusion.
