Prehospital blood for non-traumatic haemorrhage

Prehospital Blood Transfusion for Medical Causes of Hemorrhage: A Case Series
Prehospital Emergency Care · Added 1 September 2026

Retrospective observational study of prehospital whole blood for non-traumatic haemorrhagic shock across two US systems — GI bleeding (49%) and unspecified shock (43%) were the main indications, vitals improved (HR 102→96, SBP 83→106)

Study type

Case series

Design

Retrospective observational study across two fire-based EMS systems

Participants

47 patients given prehospital blood for non-traumatic haemorrhagic shock

Main finding

Of 163 transfusions, 50 (30.7%) were non-traumatic; GI bleeding 49%, unspecified shock 43%; mean HR fell 102→96, SBP rose 83→106 mmHg, shock index 1.34→1.01

Caveat

Small case series without outcome or control data; US fire-based systems

Bottom line

Hypothesis-generating

Learning goal

Weigh the role of prehospital blood transfusion for non-traumatic haemorrhage against traditional fluid resuscitation.

  This Swedish registry of 2,193 trauma patients (353 penetrating) found penetrating trauma patients were younger (median 34 vs 49 years), more often male (78% vs 66%), more frequently in shock on arrival (5.9% vs 2.2%), and more likely to require emergency surgery (53% vs 30%) and early blood transfusion (20% vs 4.5%).
