Filter by:Massively bleeding trauma patients have higher odds of mortality, increased hospital length of stay, and increased need for transfusion if they become hypothermic. Hypothermia is independently associated with mortality in traumatically injured patients due to its negative physiologic effects on hemostasis, cardiorespiratory and renal function. Current warming strategies increase the logistical difficulty of transferring patients (which is frequent during the initial hours of trauma care) or must be changed at frequent intervals. Prehospital, military, and intraoperative studies have suggested chemical warming blankets as a pragmatic strategy to manage hypothermia. A recent pilot study (manuscript under review) at our institution demonstrated the feasibility of using the Ready-Heat® (TechTrade LLC, Orlando, FL, USA) chemical heating blanket in the initial phases of hospital care in bleeding trauma patients requiring a mass hemorrhage protocol (MHP). These self-warming blankets provide warmth over 8 hours at up to 40 degrees Celsius, carrying the advantage of portability with no continuous electric power requirement. Furthermore, the Ready-Heat blanket may be more effective than current strategies for rewarming patients at high risk of developing hypothermia. STAYWARM-2 will be the first randomized controlled trial performed in-hospital to evaluate a self-warming blanket to address hypothermia in massively bleeding trauma patients within the initial hours of hospital arrival. This study will help to determine the efficacy and feasibility of using chemical heating blankets for hypothermia in the early hours of hospital care. This has potential to reduce the overall workload of direct care clinicians, freeing them for other patient care duties. Additionally, the intervention may achieve enhanced thermoregulation compared to current strategies, improving patient care and comfort, and avoiding the clinical complications related to hypothermia. Findings from this preliminary study may provide data for a future grant to launch a larger randomized controlled trial in the prehospital/in-hospital trauma setting to optimize the care of patients at risk of developing hypothermia.
This study is designed to evaluate the effect of early albumin transfusion within massive transfusion protocol on fluid balance and reduced requirement of transfusion.
Since the 2000s, many prognostic scores were developed to predict traumatic haemorrhage. Most of these studies were retrospectives based on registers. Due to missing data on death due to bleeding, these studies chose to predict the massive transfusion risk as a surrogate of haemorrhagic death. These scores include clinical parameters (vital signs), laboratory values (Haemoglobin, lactate, Base excess) and/or imaging (CT or ultrasound) values. The scores showing best performance are the Trauma Associated Severe Haemorrhage (TASH) score, developed and validated on the German register (DGU-Register) and the ABC score developed and validated in the United States of America. However, the majority of these scores cannot be applied at the trauma scene due to the unavailability of laboratory and imaging values. Therefore, their clinical utility remains unclear. To overcome the need for diagnostic tests, authors have developed and recently validated a clinical prognostic score in identifying trauma patients with, or at risk of, significant haemorrhage based on predicted probabilities of death due to bleeding: BATT score. This score was developed from an international cohort using data from 271 Trauma Centres in 41 countries on 5 continents and uses first clinical parameters at initial assessment. The BATT score predicts death due to bleeding and has been validated on a large population in England and Wales. It could also predict massive transfusion, as a surrogate of haemorrhagic death, earlier at the trauma scene. Its feasibility and external validation would make its clinical utility superior to other scores while identifying a greater number of patients requiring early management. Our study is an external validation of pre-existing prognostic scores of traumatic haemorrhages (TASH , ABC and BATT score) at different times of care (Scene of Injury, admission at the trauma room) in order to assess their overall performance, discrimination and calibration in the prediction of massive transfusion, and haemorrhagic death. The objective of the study is to assess a comparison of score performances (Overall performance, discrimination and calibration). Due to the study population (STR), which is partly integrated into the German DGU-Register, the investigators expect good transportability of the TASH score to the Swiss Trauma Registry in terms of overall performance, discrimination and calibration. The ABC score should show lowers results in terms of discrimination due to its validation on small cohorts exclusively in North America. The new BATT score predicting death due to bleeding has been validated on a large English cohort of more than 100,000 patients. It identifies all patients with haemorrhage and not only patients who have received a massive transfusion subject to survival bias. In this context, the BATT score provides good discrimination with only simple physiological variables available at the trauma scene. In case of its external validation on the STR as part of our study, its feasibility would make its clinical utility superior to other pre-existing scores, while identifying a greater number of patients requiring early management. Its application would activate a massive transfusion plan directly at the trauma scene and save precious time.
Injury is the leading cause of death for people between the ages of 1-44. This is especially true in trauma patients who have bleeding complications. Acute trauma coagulopathy (ATC) is associated with high transfusion requirements, longer ICU stays, and a greater incidence of multi-organ dysfunction. The cause of coagulopathy is multi-factorial. One major driver is acquired fibrinogen deficiency (hypofibrinogenemia). Fibrinogen is critical in clot formation and enhances platelet aggregation. Due to the body's limited reserve, it is the first clotting factor to fall to critical levels during life-threatening bleeding. This can impair coagulation and increases bleeding complications. There are two primary options available for fibrinogen supplementation: - Cryoprecipitate- North American standard - Fibrinogen Concentrate (FC)- European standard Consumption of coagulation factors, including fibrinogen, is another important component of ATC. To replenish these depleted coagulation factors and improve thrombin generation, two therapies are available: - Frozen Plasma (FP)- North American standard - Prothrombin Complex Concentrate (PCC)- European standard Strategies for hemorrhage and coagulopathy treatment have changed significantly over the last decade. Prompt hemorrhage control, along with targeted coagulation factor replacement, are emerging as key components of trauma care. Currently, the initiation of a massive hemorrhage protocol (MHP) results in red blood cells (RBCs) and FP transfusions in a 1:1 or 2:1 ratio. Clotting factors are replaced via FP administration. Fibrinogen supplementation is administration after lab verification or at the clinician's discretion. MHP continues until the rate of hemorrhage is under control. FC and PCC have several important advantages over cryoprecipitate and FP but there is a scarcity of data regarding their efficacy and safety of their use in hemorrhaging trauma patients. The FiiRST-2 study aims to understand if early use of FC and PCC in trauma patients at risk of massive hemorrhage will lead to superior patient outcomes. This trial will also provide safety data on early administration of FC and PCC as a first-line hemostatic therapy in trauma care, and its impact on hemostatic and other clinical endpoints.
Obstetric Hemorrhage continues to be the first cause of maternal morbidity and mortality around the world especially in middle to low income countriesThe blood components are high value resources; however, its use has been shown to be a risk factor of known complications. The aim of the study is to compare two algorithms of coagulation management in massive obstetric hemorrhage Methods A randomized prospective trial single center two arms study in patients with severe obstetric hemorrhage (PPH > 1000) 2 different transfusion protocols one guided by thromboelastometry and hemostatic drugs (protrombine complex concentrate and fibrinogen concentrate) and the second guided by standard coagulation test and hemocomponents. Sample is calculated to known variance, Analyses are intention-to-treat without imputation, with outcomes will be performed between groups using mixed-effects two level regression models. For binary outcomes, a logistic model will be used and results presented as adjusted odds ratios (ORs) alongside 95% confidence intervals (CIs). Count data will be analysed using Poisson multilevel or negative binomial models. Primary Outcome Parameter: Compare between the two protocols: Number of allogeneic blood products transfused intra-op, within 24h after screening and in-hospital (RBC, Platelets and FFP; separate and overall) Secondary Outcome Parameter: Analysis of mortality, lenth of stay admission to the ICU, hysterectomy surgical reintervencion, Transfuse associated circulatory overload, Transfusion associated Acute lung injury, health associated infection will be measured as secondary outcome.
Trauma is the leading cause of death in young people. Trauma-induced coagulopathy (TIC) encompasses several aspects of traumatic bleeding. Monitoring of coagulopathy comprises use of Point-of-Care (POC) methods, such as thromboelastography (TEG) or Thromboelastometry (ROTEM) and conventional laboratory assays (platelet count, fibrinogen level, and PT or INR). POC tests are thought to have a better performance on mortality and bleeding control than conventional tests. The aim of this study is to compare POC and conventional assays with plasma consumption as a primary outcome and 28 days mortality as a secondary one.
