Filter by:Background: Trauma is the leading cause of death in young adults worldwide and the most common causes of mortality are haemorrhage and brain injury. About 40% of trauma related deaths are due to massive haemorrhage and approximately 30% of trauma patients have an associated trauma induced coagulopathy. In order to improve outcome, the optimal care for the bleeding patient need to be further understood. Aim: The overall aim of this project is to evaluate characteristics and outcomes in patients receiving blood transfusion in the early phase after major trauma at a Level 1 trauma center in Sweden. The specific aims are: i) To describe outcome, characteristics and effects on the coagulation system in patients receiving early blood transfusion compared to those not receiving transfusion in the early phase. ii) To describe outcome, characteristics and effects on the coagulation system in patients receiving prehospital blood transfusion compared to patients where transfusion is initiated in the trauma unit. iii) To describe the effect from concurrent treatment with procoagulant drugs and intravenous fluids on outcome, characteristics and effects on the coagulation system in patients receiving blood transfusion after major trauma. Method: This is an observational study of trauma patients admitted to the Trauma Unit at the Karolinska University Hospital Solna, Stockholm, Sweden. Data from patients receiving blood transfusion (erythrocytes, plasma or whole blood) in the early phase of the resuscitation will be collected. All patients receiving transfusion within two hours from arrival will be included. Data on trauma details, injuries, physiological parameters, coagulations tests and treatment will be collected prospectively and from existing registries. The control group will consist of patients not receiving transfusion during the first two hours of care.
Trauma is a leading cause of death among people younger than 44 years. Five million people worldwide die from trauma annually. Uncontrolled haemorrhage causing traumatic-haemorrhagic shock (THS) is the leading cause of potentially preventable deaths from severe trauma. Uncorrected hypervolaemia and prolonged shock cause severe tissue hypoperfusion, vital organ ischemia and subsequently acidosis. In up to one third of trauma patients, laboratory findings suggest traumatic induced coagulopathy, which is further triggered by loss or dilution of coagulation factors. These patients have a significantly increased morbidity and mortality compared to patients with similar injury patterns without coagulopathy. Minimizing the time to surgical control of haemorrhage is key in order to improve outcome. However, immediate and goal directed volume and coagulation resuscitation including use of blood transfusion is crucial to enable survival until definitive hospital care. The primary objective of this study will be to evaluate feasibility of prehospital administration of 1 unit of human plasma and 1 unit of red blood cells, and explore association of early prehospital transfusion with early outcomes in patients presenting with THS, severe bleeding or peri-arrest state who are matching indication criteria and are transported by Helicopter Emergency Medical Service. Results of clinical examinations and laboratory variables in a group of patients receiving prehospital transfusion will be compared to matched population of patients treated before blood has been available on board. Secondary aim of the study is to detect any potential logistical and/or organisational adverse effects, incl. cost-effectiveness, in a regional trauma system with prehospital times (time of injury to trauma centre) ranging from 45 to 75 minutes.
The purpose of this research is to determine whether giving severely injured adults a drug called tranexamic acid (TXA) as soon as possible after injury will improve their chances of survival and their level of recovery at six months. After severe injury, a person may have uncontrolled bleeding that places them at high risk of bleeding to death. Coagulation (the formation of blood clots) is an important process in the body that helps to control blood loss. Up to a quarter of people that are severely injured have a condition called acute traumatic coagulopathy. This condition affects coagulation and results in the break down of blood clots (fibrinolysis) that can lead to increased blood loss and an increased risk of dying. TXA is an anti-fibrinolytic drug that might help to reduce the effects of acute traumatic coagulopathy by preventing blood clots from breaking down and helping to control bleeding. In Australia, TXA is approved for use by the Therapeutic Goods Administration (TGA) to reduce blood loss or the need for blood transfusion in patients undergoing surgery (i.e. cardiac surgery, knee or hip arthroplasty). Recent evidence from a large clinical trial (CRASH-2) showed early treatment with TXA reduced the risk of death in severely injured patients, however the majority of patients involved in the study were injured in countries where prehospital care is limited and rapid access to lifesaving treatments is limited compared to that available in countries like Australia and New Zealand. It is unclear whether TXA will reduce the risk of death to the same degree when it is given alongside other lifesaving treatments that are available to patients soon after injury in these countries. The hypothesis is that TXA given early to injured patients who are at risk of acute traumatic coagulopathy and who are treated in countries with systems providing advanced trauma care reduces mortality and improves recovery at 6-months after injury.
The purpose of the study is to evaluate the efficacy of the University of Rochester Medical Center's current Massive Transfusion Protocol. Upon arrival of trauma level one designated patients the treating team evaluates the patient's injuries. If the patient is initiated under the facilities Massive Transfusion Protocol and meets other inclusion and exclusion criteria the patient will be enrolled in the study. Study procedures include collection of a blood sample following the transfusion of each shipment, through shipment 5, of blood products outlined in the current Massive Transfusion Protocol. Each blood sample will be run on a Thromboelastograph to evaluate the patient's hematostatic state through resuscitation. One final blood sample will be collected 24 hours following the discontinuation of the Massive Transfusion Protocol and also ran on the thromboelastograph. Due to the critical need for medical intervention, consent procedure will be waived at time of enrollment. An authorized representative for the patient will be identified and approached to obtain consent for use of data collected.
The purpose of this study is to compare rapid thrombelastography (r-TEG) with conventional coagulation testing for diagnosing and treating coagulation abnormalities in severely injured patients who are likely to require transfusion therapy.
