BACKGROUND: The acute coagulopathy of trauma is often accompanied by hyperfibrinolysis. TXA can reverse this phenomenon, and, when given early, decreases mortality from bleeding. Establishing IV access can be difficult in trauma and IO access is often preferred for drug administration. Currently, there is no data on the efficacy of IO administered TXA. Our objectives were to compare serum concentrations of tranexamic acid (TXA) when given IV and intraosseous (IO) and to compare the efficacy of IO administered TXA to IV at reversing hyperfibrinolysis METHODS: Using a porcine hemorrhage and ischemia-reperfusion (IR) model, 18 swine underwent hemorrhagic shock followed by a tissue plasminogen activator (tPA) infusion to induce hyperfibrinolysis...

The in vitro haemostatic functions of fresh whole blood (FWB) are well preserved after cold storage. This study aimed to determine whether platelets derived from FWB and stored whole blood (SWB) contribute to clot formation in tissue injury after transfusion into coagulopathic rats with polytrauma/haemorrhage (T/H). The rats were resuscitated 1 h after trauma with FWB or SWB collected from green fluorescence protein (GFP) transgenic rats. After transfusion, a liver incision was made and the tissue was collected 10 min after injury to identify GFP(+) platelets by immunohistochemistry...

Trauma patients with uncontrolled hemorrhage encountering coagulopathy are often associated with poor outcome. Recently, the concept of damage control interventional radiology, which focuses on "speedy stoppage of bleeding" by interventional radiology among trauma patients with hemodynamic instability and acute traumatic coagulopathy, was proposed as an alternative to damage control surgery. N-butyl cyanoacrylate (NBCA) has been used as a liquid embolic agent in various non-traumatic situations, where it has been shown to have a high technical success rate and low recurrent bleeding rate, especially in patients with coagulopathy...

BACKGROUND: Rapidly resolving acute subdural hematomas (RRASDHs) have been described in case reports and case series but are still poorly understood. We hypothesized that a cohort analysis would confirm previously reported predictors of RRASDH including coagulopathy, additional intracranial hemorrhage, and low-density band on imaging. We also hypothesized that rapid resolution would be associated with improved trauma outcomes. METHODS: We reviewed all nonoperative acute subdural hematomas (ASDHs) treated at our center from 2011 to 2015...

PURPOSE OF REVIEW: The aim of this study was to discuss the recent developments in trauma-induced coagulopathy and the evolvement of goal-directed therapy. RECENT FINDINGS: Mortality from major trauma continues to be a worldwide problem, and massive haemorrhage remains a major cause in 40% of potentially preventable trauma deaths. Development of trauma-induced coagulopathy challenges 25-35% of the patients further increasing trauma mortality. The pathophysiology of coagulopathy in trauma reflects at least two distinct mechanisms: Acute traumatic coagulopathy, consisting of endogenous heparinization, activation of the protein C pathway, hyperfibrinolysis and platelet dysfunction, and resuscitation associated coagulopathy...

Worldwide, hemorrhagic shock in major trauma remains a major potentially preventable cause of death. Controlling bleeding and subsequent coagulopathy is a big challenge. Immediate assessment of unidentified bleeding sources is essential in blunt trauma patients with hemorrhagic shock. Chest/pelvic X-ray in conjunction with ultrasonography have been established classically as initial diagnostic imaging modalities to identify the major sources of internal bleeding including intra-thoracic, intra-abdominal, or retroperitoneal hemorrhage related to pelvic fracture...

PURPOSE OF REVIEW: Damage control surgery (DCS) represents a staged surgical approach to the treatment of critically injured trauma patients. Originally described in the context of hepatic trauma and postinjury-induced coagulopathy, the indications for DCS have expanded to the management of extra abdominal trauma and to the management of nontraumatic acute abdominal emergencies. Despite being an accepted treatment algorithm, DCS is based on a limited evidence with current concerns of the variability in practice indications, rates and adverse outcomes in poorly selected patient cohorts...

BACKGROUND: Damage control surgery (DCS) was a major paradigm change in the management of critically ill trauma patients and has gradually expanded in the general surgery arena, but data in this setting are still scarce. The study aim was to evaluate outcomes of DCS in patients with general surgery emergencies. METHODS: Between 2005 and 2015, 164 patients (104 men, age 66) underwent DCS for non-traumatic abdominal emergencies. The decision to perform DCS was triggered by the presence of at least one trauma DCS criterion: hypotension (<70 mmHg), hypothermia (<35 °C), acidosis (pH < 7...

Recognition of the acute coagulopathy of trauma and the limits of reconstituting whole blood with conventional blood components has led to a radical change in the way trauma patients with severe injuries are resuscitated. Massive transfusion protocols (MTP) have evolved toward the administration of conventional blood components in fixed ratios. Administration of a 1:1:1 unit ratio of fresh frozen plasma to whole-blood-derived platelets to packed red blood cells is now the most common strategy and the stated goal of directors of >80% of the level I trauma centers in the United States...

Here, we present the case of a patient with the findings of an early intracardiac thrombus and a pulmonary embolus after major trauma. A large clot was identified extending from the inferior vena cava into the right atrium and ventricle in the setting of preserved right ventricular function. Post-traumatic intracardiac thrombus is extremely rare and no comparable cases have previously been described in the absence of a congenital heart defect and obvious myocardial injury. Best practice afterpost-traumatic intracardiac thrombus is not well established but we found that early inferior vena cava filter placement and treatment with therapeutic coagulation resulted in clinical improvement, resolution of the thrombus and no further emboli...

Trauma-induced coagulopathy is a primary factor in many trauma-related fatalities. Management hinges upon rapid diagnosis of coagulation abnormalities and immediate administration of appropriate hemostatic agents. Use of crystalloids and packed red blood cells has traditionally been the core of trauma resuscitation, but current massive transfusion protocols include combination therapy with fresh frozen plasma and predefined ratios of platelets to packed red blood cells, limiting crystalloid administration. Hemostatic agents such as tranexamic acid, prothrombin complex concentrate, fibrinogen concentrate, and, in cases of refractory bleeding, recombinant activated factor VIIa may also be warranted...

BACKGROUND: Identifying trauma patients that need emergent blood product transfusion is crucial. The Trauma Induced Coagulopathy Clinical Score (TICCS) is an easy-to-measure score developed to meet this medical need. We hypothesized that TICCS would assist in identifying patients that need a transfusion in a large cohort of severe trauma patients from the TraumaRegister DGU(®) (TR-DGU). MATERIALS AND METHODS: A total of 33,385 severe trauma patients were extracted from the TR-DGU for retrospective analysis...

BACKGROUND: Trauma-induced coagulopathy (TIC) is a common feature after severe trauma. Detection of TIC is based upon classic coagulation tests including international normalized ratio (INR) value. Point-of-care (POC) devices have been developed to rapidly measure INR at the bedside on whole blood. The aim of the study was to test the precision of the Coagucheck® XS Pro device for INR measurement at hospital admission after severe trauma. METHODS: We conducted a prospective observational study in a French level I trauma center...

OBJECTIVE The goal of this study was to identify factors that contribute to the formation of acute spinal epidural hematoma (SEH) by correlating etiology, age, site, clinical status, and treatment with immediate results and long-term outcomes. METHODS The authors reviewed their series of 15 patients who had been treated for SEH between 1996 and 2012. In addition, the authors reviewed the relevant international literature from 1869 (when SEH was first described) to 2012, collecting a total of 1010 cases. Statistical analysis was performed in 959 (95%) cases that were considered valid for assessing the incidence of age, sex, site, and clinical status at admission, correlating each of these parameters with the treatment results...

The authors present the case of a 46-year-old woman who was admitted to their institution after suffering acute intratumoral hemorrhage. There was no history and evidence of neoplasms, trauma, seizures and coagulopathy in the patient. Surgery was performed for evacuation of the hematoma and tumor excision after brain CT scan. Post operative results her neurologic function recovered completely. The pathology reports revealed angioblastic meningioma. The key to make an early and accurate diagnosis is good radiological examination, and definitive surgery can bring a more favorable outcome, lowering the morbidity and mortality rate...

BACKGROUND: The use of anticoagulants or antiplatelet medications has become increasingly common and is a well-established risk factor for worsening of hemorrhages in trauma patients. The current study addresses the need to investigate the efficacy of point-of-care tests (POC) as an adjunct to conventional coagulation testing in traumatic brain injury (TBI) patients. METHODS: A retrospective review of 190 TBI patients >18 years of age who underwent both conventional and POC testing as part of their admission coagulopathy workup was conducted...

The emergency management of acute severe bleeding in trauma patients has changed significantly in recent years. In particular, greater attention is now being devoted to a prompt assessment of coagulation alterations, which allows for immediate haemostatic resuscitation procedures when necessary. The importance of an early trauma-induced coagulopathy (TIC) diagnosis has led physicians to increase the efforts to better understand the pathophysiological alterations observed in the haemostatic system after traumatic injuries...

BACKGROUND: The fresh frozen plasma (FFP) transfusion threshold and timing for traumatic brain injury (TBI)-associated coagulopathy are controversial. Thus, a multicenter retrospective study was conducted to determine whether or not FFP transfusion is associated with poor outcomes after severe TBI. METHODS: Data from decompressive craniotomy after blunt force trauma that took place between December 2013 and June 2016 were collected in a multicenter chart. The primary outcomes were mortality and survival, as well as worse outcomes (defined as a Glasgow Outcome Scale [GOS] score ≤3) and better outcomes (GOS score ≥4)...
