Filter by:Study Design: Single-center, not-randomized, open-label, two-arms controlled pilot clinical trial. Health Condition: Patients with severe trauma with a need for transfusion and categorized as priority 0 or 1 according to the Catalan Health Service (CatSalut) Polytrauma Code (PPT)
It is reported that high mobility group box 1 (HMGB1), a non-histone nuclear protein, can serve as an alarmin with damage associated molecular patterns to activate immune responses in the early stages of hemorrhagic shock (HS). However, the origin of HMGB1 and how it is released following HS is poorly understood. In this study, we teased out this mechanism. We try to record the concentration of serum HMGB1 protein following HS in clinical patients.
In this study, we will explore the feasibility of a randomized controlled trial that will compare high protein dose from ICU day 6 to 14 with moderate protein intake.
Despite advances in trauma resuscitation, a paucity of therapeutic interventions are available early enough to reduce the downstream morbidity and mortality attributable to hemorrhage, shock and coagulopathy. Due to the time sensitive nature of the treatment of hemorrhage, the ideal resuscitation intervention would entail use of a blood product containing all essential hemostatic components, closest to time of injury, where prevention or reversal of the devastating downstream consequences of shock and coagulopathy can occur. This proposal will characterized the efficacy of whole blood resuscitation initiated in the prehospital setting to patients in hemorrhagic shock which represents this ideal intervention post-injury. These results will have great potential to dramatically change the way trauma resuscitation occurs today.
The California Prehospital Antifibrinolytic Therapy (Cal-PAT) study seeks to evaluate the safety and efficacy of Tranexamic Acid (TXA) use in the civilian prehospital and in hospital setting in cases of traumatic hemorrhagic shock.
In shock patients, fluid resuscitation, infusion of vasopressors and transfusion are guided on hemodynamic macrovascular parameters. Analysis of sublingual microcirculation in shock patients is predictive of mortality and organ dysfunction. To optimize the quality of the resuscitation in shock patients, it could be useful to have an assessment of sublingual microcirculation in addition to the macrovascular parameters usually assessed by the nurses. But, this requires to have a monitor of sublingual microcirculation easy to use and to analyze at the bedside. The primary outcome of the present study is to test the ability of visual analysis of sublingual microcirculation by nurses to predict needs for fluid challenge, vasopressors or transfusion in patients in shock. After ICU admission and study inclusion, the nurses in charge of the patient will perform a set of measurements of macrocirculatory and microcirculatory parameters every 4 h during the first three days after ICU admission and before and after every hemodynamic therapeutic intervention, such as fluid challenge, transfusion of red blood cells or change in catecholamine rate. The secondary outcomes are to test 1/ to test the ability of visual analysis of sublingual microcirculation to predict organ dysfunction (SOFA score), and 2/ to evaluate the relationship between hemodynamic macrovascular and microvascular parameters. Intensive care patients in shock who need sedation, mechanical ventilation and invasive hemodynamic monitoring (Pulse Contour Cardiac Output (PiCCO 2 device)) will be included. In addition, patients will be included only when patients will obviously stay more than 24 hours in the ICU.
The LITES Network is an operational trauma center consortium which has the expertise, track record and confirmed capabilities to conduct prospective, multicenter, injury care and outcomes research of relevance to the Department of Defense (DoD). Hemorrhage and Traumatic Brain Injury (TBI) are responsible for the largest proportion of all trauma-related deaths. It is the poly-trauma patient who suffers both hemorrhagic shock and traumatic brain injury where a paucity of evidence exists to direct treatment, limiting the development of beneficial trauma practice guidelines. The use of Whole Blood (WB) for early trauma resuscitation has been touted as the 'essential next step' in the evolution of trauma resuscitation. Despite its historical and more recent use, little is known regarding WB's benefit relative to the 'current practice' ratio-based blood component therapy in the acutely bleeding patient, and even less is known regarding its effects in patients with TBI. AIM#1: Evaluate patient centered outcomes associated with early whole blood resuscitation practice as compared to component resuscitation in poly-trauma patients with hemorrhagic shock and further characterize outcome benefits in those with traumatic brain injury. AIM#2: Characterize blood pressure and resuscitation endpoints during the acute resuscitation phase of care and the associated/attributable outcomes for traumatic brain injury in patients with hemorrhagic shock. General Hypothesis #1: Whole blood resuscitation will be associated with improved mortality and resuscitation outcomes in poly-trauma patients and long term neurological outcome in those patients with traumatic brain injury as compared to those resuscitated with component therapy. General Hypothesis #2: Differences in prehospital and acute phase resuscitation systolic blood pressure will be associated with differential outcomes in patients with traumatic brain injury at discharge and at 6 months. Study Design: The LITES network will perform a multicenter, prospective, observational cohort study over a 4 year period to determine the impact of whole blood resuscitation in trauma patients with hemorrhagic shock at risk of large volume resuscitation with and without TBI. Early whole blood resuscitation will be compared to standard component resuscitation. The study will also further characterize blood pressure and resuscitation endpoints in poly-trauma patients with traumatic brain injury. Six Trauma sites with appropriate characteristics will be selected from 12 LITES Network sites across the country. Study Setting: The study will be performed utilizing busy level I trauma centers within the LITES Network located across the country, at sites where either whole blood has currently been incorporated into standard of care or where component blood transfusion is being utilized for patients in hemorrhagic shock at risk for large volume resuscitation. Study Population: The study will focus on patients who suffer blunt or penetrating injury, transported to a SWAT participating LITES trauma center with evidence of hemorrhagic shock at risk of large volume blood resuscitation.
Hemorrhagic shock is a pathologic state in which intravascular volume and oxygen delivery are impaired. During circulatory failure associated with hypovolemia and low cardiac output, redistribution of blood flow caused by increased vasoconstriction results in decreased perfusion of the skin. Skin temperature and capillary refill time has been advocated as a measure of peripheral perfusion.
In this study the impact of two CE marked and FDA approved sternal needles in comparison to intravenous access on the flow-rate of autologous reinfusion of whole blood and the possible hemolysis of red cells post-transfusion in a population of healthy military officers is investigated.
The purpose of this study is to demonstrate safety, effectiveness and benefit-risk profile of ResQFoam for the inhospital treatment of exsanguinating, intraabdominal haemorrhage due to trauma in patients where emergent laparotomy is required.
