Filter by:Coagulopathy after cardiopulmonary bypass (CPB) is associated with increased morbidity and mortality. Clot formation and clot stability are important factors in coagulation and hemostasis. As such platelet dysfunction and impaired thrombin generation play a central role in bleeding after cardiac surgery. The primary objective of this study is to evaluate the relationship between point-of-care determined platelet function and thrombin generation and postoperative bleeding in infants and young children undergoing cardiac surgery with cardiopulmonary bypass adjusting for clinically important confounding factors.
The goal of the study is to determine whether the use of Human Fibrinogen Concentrate (RiaSTAP) will decrease blood loss and the need for component blood therapy in neonates and infants undergoing cardiopulmonary bypass.
The aim of this study is to evaluate early clotting disorders through thromboelastogram and anticoagulant proteins levels (maybe also endothelial markers) and liver function by indocyanine green clearance after major liver resection and search for a potential relationship between them.
A prospective study intended to examine the effect of topical Voltaren-Ophtha 0.1% eye drops after cataract surgery on INR levels (international normalized ratio) in patients taking warfarin.
This prospective, randomized, multicenter study is performed to determine whether prothrombin complex concentrates confers any benefits over fresh frozen plasma in adult neurological patients with coagulation disorders (PT value less than 60%).
The World Federation of Hemophilia (WFH) is conducting the pilot phase of an international, observational, World Bleeding Disorders Registry (WBDR). This pilot phase will assess the feasibility of conducting an expanded WBDR to more centres with a more comprehensive case report form, around the world.
The purpose of this study is to demonstrate the feasibility and effectiveness of anticoagulation self-monitoring coupled with an educational intervention in a minority underserved population.
With the advent of measures to try to decrease the incidence of transfusion-related acute lung injury (TRALI), the Blood Bank industry is attempting to avoid collection of plasma from female donors who have been pregnant in order to reduce the transfusion of plasma that may contain HLA antibodies. This has led to a decrease in the number of donors available for the production of fresh frozen plasma (FFP). Per Blood Bank regulatory standards in the United States, FFP must be frozen within 8 hours of collection. Plasma that is frozen within 24 hours of collection is called FP24, and it is produced when whole blood cannot be processed within the 8-hour time period for the generation of FFP. Studies of coagulation factors in FFP and FP24 have shown that coagulation factor activities are adequate to maintain hemostasis in both products. Many hospitals are using FFP and FP24 interchangeably in adults, and occasional hospitals are using these products interchangeably in neonates. However, studies concerning the use of FP24 in neonates have not been performed. The investigators propose a single center prospective pilot study comparing the clinical efficacy of FFP vs. FP24 in 50 nonsurgical neonates and babies up to age 6 months requiring plasma for an International Normalization Ratio (INR) of 1.5 or more. This protocol describes a pilot study to compare the use of FFP with FP24 in nonsurgical neonates. Use of plasma in these cases is mostly for patients with perinatal hypoxia or necrotizing enterocolitis and an INR of 1.5 or more. Transfusion of plasma (10 to 15 ml/kg) is performed for these patients approximately every 8, 12, or 24 hours, as deemed indicated by the patient's clinicians, and monitored with prothrombin time (PT), partial thromboplastin time (PTT), and INR.
- Haemorrhage in severe trauma is a significant cause of mortality and is potentially the most preventable cause of death in trauma patients - Trauma Induced Coagulopathy (TIC) is a complex coagulopathy associated with severe trauma - Hypo/dysfibrinogenaemia plays an important role in TIC - Early replacement of fibrinogen may improve outcomes - Fibrinogen replacement is potentially inadequate in standard fixed ratio Major Haemorrhage Protocols (MHP) utilising Plasma and/or Cryoprecipitate - The majority of centres utilise cryoprecipitate for additional fibrinogen supplementation as part of a MHP - Cryoprecipitate administration is often delayed (between 60 - 120 minutes) in a fixed ratio MHP - It is clear early intervention in severe traumatic haemorrhage is associated with improved outcomes - CRASH 2 and PROPPR studies - Increasing interest in the use of Fibrinogen Concentrate (FC) in severe bleeding but not supported by high level evidence - Benefits of FC - viral inactivation, known dose, easily reconstituted, can be administered quickly in high dose and stored at room temperature in the trauma resuscitation bay - No previous studies comparing FC and Cryoprecipitate in bleeding trauma patients - Fibrinogen supplementation will be guided by an accepted ROTEM targeted treatment algorithm - It will be a pilot, multi-centre randomised controlled trial comparing FC to Cryoprecipitate (current standard practise in fibrinogen supplementation) - Hypothesis: Fibrinogen replacement in severe traumatic haemorrhage can be achieved quicker with a more predictable dose response using Fibrinogen Concentrate compared to Cryoprecipitate - It is imperative that robust and clinically relevant trials are performed to investigate fibrinogen supplementation in trauma before widespread adoption makes performing such studies unfeasible
In severe bleeding due to trauma, a decrease in coagulation factors maintains and promotes bleeding. The plasma allows, through its contribution of coagulation factors, early prevention or correction of this post-trauma induced coagulopathy. This study aims to measure the effectiveness of pre-hospital FLYP administration in case of traumatic hemorrhagic shock, in the occurrence or the treatment of a post traumatic induced coagulopathy. Study Design This is a randomized controlled multicenter open label study in two parallel groups. Eligibility criteria : adult, victim of a hemorrhagic shock of traumatic origin with [systolic blood pressure <70 mmHg] or Shock Index >1.1 The patients will receive either FLYP either the usual treatment as given in the recommendations for best practice. The primary endpoint is the International Normalized Ratio (INR) at hospital admission. The study must confirm the link between causality of early administration of plasma in improving post-traumatic coagulopathy. The study must show safe usage in out-of-hospital situations and the ability of medical staff to meet the requirements of the health authorities in terms of product use as well as in terms of traceability of the victims and the treatment they received.
