Официальное название

Early and Precise Application and Evaluation of Tranexamic Acid in Patients With Traumatic Bleeding Based on Dynamic Monitoring of Thromboelastography

Обзор

Trauma is an important global public health problem and is the leading cause of death in people under 40 years old. Studies have shown that early prehospital administration of TXA 1 g intravenously followed by a continuous infusion of 1 g tranexamic acid (TXA) over 8 hours ( 1+1 regimen) is effective in reducing mortality in trauma patients, but there is a residual risk of death. This clinical study utilized real-time dynamic monitoring of coagulation fibrinolytic status in trauma patients using thromboelastography (TEG) to assess the need for a second or even multiple administrations of TXA (1+X regimen) in addition to the administration of 1 g of TXA intravenously and to compare the two mortality rates, thus guiding the early and precise use of TXA in trauma patients to potentially reduce mortality in trauma patients while decreasing thromboembolic risk. The present study is an optimization and addition to the TXA 1+1 regimen. Currently, no relevant studies have been reported. This study has important clinical significance for standardizing the early and precise use of TXA in trauma patients and improving the effectiveness and safety of TXA.

Подробное описание

Trauma, an important global public health problem, is the leading cause of death in people under 40 years of age. Post-traumatic hemorrhage deaths account for approximately half of the 4.6 million injury deaths worldwide each year . Their early deaths are due to severe hemorrhage and later to traumatic brain injury or secondary multi-organ dysfunction. Although resuscitation protocols for post-traumatic hemorrhage have improved over the past decade, shifting from massive rehydration aimed at perfusion to "damage control resuscitation" that prioritizes correction of early coagulation abnormalities, current transfusion therapies are still unable to correct coagulation during sustained bleeding. In recent years, the hemostatic drug therapy represented by Tranexamic Acid (TXA) has incorporated antifibrinolytic drugs into the global trauma practice guidelines . Overseas studies have shown that the use of TXA within 3 h after trauma can reduce the mortality rate due to trauma bleeding \[5,6\], but domestic clinical studies in this area are less reported, which is worthy of in-depth study.

The use of TEG for real-time dynamic monitoring of coagulation and fibrinolytic status in trauma patients to guide the early and precise application of TXA may be effective in reducing the mortality rate of severely traumatized patients, as well as reducing the occurrence of thromboembolism. Since the half-life of tranexamic acid is 1.8h , the present study is to use TEG to monitor the coagulation fibrinolytic status of traumatized patients in real time, and to assess the need for secondary or even multiple administrations of TXA (up to three times) (i.e., the 1+X regimen) after two half-life periods of TXA are about to be metabolized on the basis of the intravenous injection of 1g of TXA and to compare the two mortality rates, so that the early and precise use of TXA in traumatized patients can be guided, which may be effective in reducing the occurrence of thromboembolism. patients to guide the early and precise use of TXA in trauma patients, potentially reducing mortality in trauma patients while reducing the risk of thromboembolism. The present study is an optimization and addition to the TXA 1+1 regimen. Currently, there are no relevant literature reports and no references in relevant clinical trial registry websites. This study is clinically important for standardizing the early and precise use of TXA in trauma patients and improving the effectiveness and safety of TXA.

Вмешательства

Препарат Tranexamic acid (TXA) injection
All enrolled patients with acute trauma were given 1 g tranexamic acid (TXA) within 3 h after trauma, which was infused intravenously within 10 min, and randomized into groups. After admission, the first laboratory examination was conducted for both groups. The 1+1 control group continued to infuse 1g TXA within 8 h.

After admission, the first laboratory examination was conducted for both groups. the 1+x study group was subjected to thromboelastography (TEG) without TXA for the time being, and the coagulation and fibrinolytic status of the patients was judged according to the results of TEG (LY30, EPL value), and the patients diagnose
