简要总结
A prospective, randomized controlled trial of fibrinogen concentrate (FC) plus standard of care versus standard of care alone in adult trauma patients with major bleeding or presumed major bleeding is developed to evaluate the efficacy and safety of prehospital administration of FC in trauma patients with suspected hypofibrinogenemia and active bleeding or presumed to be bleeding.
The main endpoints are:
- Plasma fibrinogen levels in the first blood sample drawn at the patient's arrival at the trauma room and/or similar emergency bay dedicated to trauma and reanimation above the critical threshold of 2.0 g/l. As fibrinogen decreases early in trauma, its deficiency predicts massive bleeding and death.
- Administration feasibility of FC within the prehospital setting.
Patients will be randomly assigned to receive either standard trauma care or standard trauma care plus administration of FC.

Pre-hospital Administration of Fibrinogen Concentrate in Patients with Suspected Trauma-Induced Coagulopathy (PAF-TIC)
Keywords: Trauma, Coagulopathy, Trauma induced coagulopathy, Fibrinogen, Clot
Introduction Trauma is a leading cause of morbidity and mortality worldwide, with hemorrhage being one of the primary preventable factors contributing to trauma-related deaths. The management of trauma induced coagulopathy (TIC) is a critical aspect of the resuscitation of severely injured patients. Fibrinogen, a key factor in the coagulation cascade, is often rapidly depleted in cases of severe trauma, leading to compromised clot formation and stability. The use of fibrinogen concentrate (FC) in the pre-hospital setting has emerged as a potential intervention to address this issue and improve patient outcomes.
Recent studies have explored the feasibility, efficacy, and safety of administering FC in both prehospital and emergency departments . A randomized feasibility trial demonstrated that early infusion of FC is attainable and can increase plasma fibrinogen concentration during trauma resuscitation, suggesting that larger trials are justified. Similarly, a prospective, randomized, placebo-controlled trial found that prehospital administration of FC improved blood clot stability and protected against early fibrinogen depletion. These findings are supported by a systematic review, which, despite methodological limitations, indicated that FC administration may reduce the need for blood product transfusion.
In a recently published Australian prehospital study, significant coagulopathy was found to develop in 36% of patients transported to trauma centers and could be found in some patients as early as within 30 minutes of injury. Low fibrinogen was the commonest coagulopathy found among trauma patients and was linked to higher in-hospital mortality rates and an increased need for blood transfusions.

研究组 & 干预措施
Standard trauma care
Determined by national guidelines on trauma, elaborated by the National Institute of Medical Emergency and taught to prehospital physicians and nurses at the time of enrollment in prehospital teams to ensure consistency in the treatment of trauma patients nationwide .
干预措施: Standard trauma care (Drug)
Standard trauma care plus administration of fibrinogen concentrate (FC).
The patients assigned to the intervention arm will receive the administration of a fixed dose of 4g fibrinogen, as per previous studies.
干预措施: Fibrinogen concentrate (Drug)
结局指标
主要结局
Plasma fibrinogen levels
时间窗: First 30 minutes on hospital arrival
Plasma fibrinogen levels in the first blood sample drawn at the patient's arrival at the trauma room and/or similar emergency bay dedicated to trauma and reanimation above the critical threshold of 2.0 g/l. As fibrinogen decreases early in trauma, its deficiency predicts massive bleeding and death.
Administration feasibility
时间窗: Prehospital setting
Proportion of Patients Successfully Administered Fibrinogen Concentrate within 60 Minutes Post-Injury. This assessment aims to measure the proportion of eligible trauma patients who receive fibrinogen concentrate (FC) within 60 minutes of their injury. Feasibility will be determined by rigorously evaluating the time it takes to administer the treatment, adherence to the protocol, and any operational challenges encountered. Data will be meticulously compiled to calculate the average time it takes to administer the treatment, the rate of successful protocol adherence, and to identify common barriers to timely FC administration.
次要结局
- Mortality(Day 7 and day 28)
- ICU Length of Stay(Up to 90 days)
- Multiple Organ Failure(Up to 90 days)
- Change of fibrinogen levels(Day 1)
- Change of clot stability upon arrival(First 30 minutes on hospital arrival)
- Clot Formation(Up to 90 days)
- Clot Stability(Up to 90 days)
- Incidence of Thromboembolic events(Up to 7 days after hospital admission)
