In this small propensity matching study looking at prehospital blood transfusion vs. emergency department blood transfusion in trauma patients aged 0-17 these authors found a better 24 and in-hospital mortality for patients who received prehospital blood transfusion compared to those receiving blood on arrival to the emergency department.
“The number needed to transfuse in the prehospital setting to save 1 child's life was 5 (95% CI, 3-10).”
