Trauma is the leading cause of death in people 44 years of age or younger. After major trauma, such as following high-speed motor vehicle collision, bleeding coupled with clotting defects is responsible for most of deaths in the first hours of hospital admission. Of note, these bleeding-related deaths are potentially preventable. Accordingly, the initial in-hospital management of severely injured patients focuses on stopping bleeding, replacing blood loss and correcting clotting defects. Recently, animal and human research demonstrated that one of the major clotting defects following injury and bleeding is the drop in blood levels of fibrinogen (a clotting factor), which is detected on hospital admission in severely injured patients. These low fibrinogen levels are associated with increased blood transfusion and death. However, in North America, the standard of care for replacing low fibrinogen requires the use of cryoprecipitate, which is a frozen blood product with long preparation time, and similarly to other blood products, carries the risk of viral transmission and transfusion complications. Alternately, many Europeans countries where cryoprecipitate has been withdrawn from the market due to safety concerns, use fibrinogen concentrate. Fibrinogen concentrate undergoes pathogen inactivation, which is a process to eliminate the risk of transmitting viruses, bacteria and parasites, is likely a safer and faster alternative to cryoprecipitate. In Canada, fibrinogen concentrate is licensed for congenital low fibrinogen only. Although preliminary data suggest that fibrinogen supplementation in trauma is associated with reduced bleeding, blood transfusion, and death, the feasibility, safety and efficacy of early fibrinogen replacement remains unknown. We proposed to conduct a feasibility randomized trial to evaluate the use of early fibrinogen concentrate against placebo in injured patients at our trauma centre. A pilot trial is necessary to demonstrate the feasibility of rapidly preparing, delivering, and infusing fibrinogen concentrate as an early therapy to prevent excessive bleeding in trauma. This feasibility trial will provide preliminary safety and clinical outcome data to inform the design of larger trials; which ultimately aims to prevent bleeding-related deaths in the trauma population.
Anti-inflammatory tablets (non-steroidal anti-inflammatory drugs) continue to be used commonly worldwide to relieve pain caused by arthritis. Likewise, aspirin is used by many patients in order to prevent blood clots. Despite their desired benefits, these medicines can cause internal bleeding from the digestive system. The source of this bleeding can be obvious (overt), or obscure and thought to come from the small intestine. Obscure bleeding can show as anemia due to lack of iron in the blood. Small intestine ulcers are now easily diagnosed using an endoscope the size of a big pill (video capsule endoscopy). Small bowel ulcers are not related to stomach acid and therefore do not heal using remedies usually taken to stop acid formation. A different drug, misoprostol, consists of a chemical (prostaglandin) that is usually lacking in patients using aspirin or anti-inflammatory drugs. Misoprostol is licenced to heal stomach and duodenal ulcers in patients using these drugs. Our hypothesis is that misoprostol might be effective in healing small bowel ulcers as suggested by pilot studies; however, such works only included small numbers of patients, did not include control groups and both patients and investigators knew the nature of the tablets used. To test this hypothesis, we propose to compare misoprostol to a dummy tablet. The numbers of subjects to be studied have been calculated using established statistical methods
Although endoscopic colonic polypectomy has been an established procedure for two decades, the risk of bleeding is still higher after resecting of pedunculated polyps, because of the presence of a large artery in the stalk. Preventive methods such as endoloop and epinephrine injection have been proposed in the management of postpolypectomy bleeding in large colonic polyps. For prophylactic clip, there was no randomized controlled study assessing the efficacy in the prevention of postpolypectomy bleeding for the large pedunculated polyps. So the investigators designed a randomized controlled trial to confirm the efficacy of application of prophylactic clip in the prevention of postpolypectomy bleeding in large polyps.
A new topical hemostatic agent composed of a specifically-formulated porous collagen matrix, coated on one side with a thin protein bonding layer (known as NHS-PEG) has been reported to be extremely effective, in addition to traditional means, in terminating bleeding during cardiac operations with control rates as high as 97,5%. The investigators compared such hemostatic agent (Hemopatch; Baxter Inc, Deerfield, IL) with traditional optimized hemostasis routine. Following sample size calculation, in a prospective randomized study design, 100 patients will be treated with Hemopatch and 100 patients will receive traditional optimized hemostasis routine (comparison group). To make the two cohorts as comparable as possible enrollment will be restricted to moderately bleeding vascular anastomosis of Dacron grafts to ascending aorta or moderately bleeding transversal aortotomy. Study endpoints are the following: rate of successful intraoperative hemostasis (identified by cessation of bleeding in less than 3 minutes from application) and time required for hemostasis; overall postoperative bleeding; rate of transfusion of blood products; rate of surgical revision for bleeding; postoperative morbidity; and intensive care unit stay.
The investigators compare the effectiveness and adverse effects of I.V carbetocin versus oxytocin & ergometrine I.V for prevention of postpartum haemorrhage following cesarean section.
The goal of this study is to use contrast enhanced ultrasound to determine the degree to which flow is reduced during application of a junctional tourniquet (JT). Contrast enhanced ultrasound is performed to quantify thigh and calf perfusion at baseline and during application of the JT
This Phase 1 study consists of 2 parts. Part 1 will be an open-label, randomized, 2 treatment, 2-way crossover study. Part 2 will be a double-blind (Sponsor unblinded), randomized, placebo controlled, sequential descending prothrombin complex concentrate dose, 2 sequence, 2 period crossover study. In both parts of the study, the assessor of BD and BV will remain blinded. In Part 2 of the study, both the subject and the clinic staff involved in study conduct will be blinded (with the exception of the pharmacist or nurse who prepares the blinded individual treatments from open-label supplies). The study programmer and statistician will also be blinded to treatment assignment. The Sponsor will remain unblinded for both parts of the study.
In this multicenter project, we will introduce AWARE (electronic interface) Using a cloud-based technology . The goal of this project is to improve compliance with best practice through the use of a new acute care interface with built-in tools for error prevention, practice surveillance and reporting (ProCCESs AWARE - Patient Centered Cloud-based Electronic System: Ambient Warning and Response Evaluation).The goal of this project is to develop and test a novel acute care interface with built-in tools for error prevention, practice surveillance, decision support and reporting (ProCCESs AWARE - Patient Centered Cloud-based Electronic System: Ambient Warning and Response Evaluation). In preliminary studies, these novel informatics supports built on an advanced understanding of cognitive and organizational ergonomics, have significantly decreased the cognitive load of bedside providers and reduced medical errors. Using a cloud-based technology, AWARE will be uniformly available on either mobile or fixed computing devices and applied in a standardized manner in medical and surgical ICUs of five geographically diverse acute care hospitals predominantly serving Medicare and Medicaid patients. The impact of ProCCESs AWARE on processes of care and outcomes in study ICUs; expected to enroll more than 10,000 critically ill patients during the study period.
