Empiric prehospital transfusion bundle for traumatic haemorrhagic shock

Implementation of an Empiric Transfusion Bundle for Out of Hospital Patients With Haemorrhagic Shock: a Prospective Observational Study C-TOP - Coagulation Therapy for Out-of-Hospital Patients

Medical University of Graz · NCT06891131

We will try giving fibrinogen, plasma, and tranexamic acid before hospital arrival to adults with suspected life‑threatening bleeding from trauma to see if outcomes and safety change.

What this trial studies

This is a prospective observational implementation of a prehospital transfusion bundle delivered by the Medical University of Graz emergency doctor response team and the Graz HEMS. Only adults with suspected life‑threatening traumatic bleeding who receive prehospital transfusion and are transported to the resuscitation room at the Medical University of Graz will be included. The bundled intervention follows local SOPs and consists of two units of fibrinogen and plasma plus tranexamic acid at 10–20 mg/kg. The project aims to collect real‑world data on benefits and harms after introducing this change to prehospital routine care.

Who should consider this trial

Good fit: Adults (18 years or older) with confirmed or suspected life‑threatening bleeding from trauma who receive prehospital transfusion and are transported to the Medical University of Graz resuscitation room.

Not a fit: Patients with a recent history of thromboembolic events (within 6 months), known or suspected pregnancy, those who refuse participation, or trauma patients who do not receive prehospital transfusion or are not brought to the Graz resuscitation room are unlikely to benefit from this implemented bundle.

Why it matters

Potential benefit: If successful, earlier delivery of fibrinogen, plasma, and tranexamic acid before hospital arrival could reduce bleeding, lower subsequent transfusion needs, and improve survival or recovery for patients with traumatic haemorrhagic shock.

How similar studies have performed: Components such as tranexamic acid and prehospital plasma have shown benefit or mixed results in prior studies, but combining fibrinogen, plasma, and TXA as a routine prehospital bundle is relatively novel and not yet proven in randomized trials.
