In trauma resuscitation, what is the role of prehospital blood products?

• A. To replace crystalloids entirely
• B. They reduce infection risk
• C. They are never used
• D. They improve initial hemodynamics and oxygen delivery when crystalloids would cause dilutional coagulopathy

Answer: (D)

In trauma resuscitation, the aim is to restore circulating volume while preserving coagulation and oxygen delivery. Using blood products early provides red blood cells to improve oxygen carrying capacity and plasma/platelets to support clotting, which helps maintain hemostasis. Large volumes of crystalloids can dilute coagulation factors and platelets, leading to dilutional coagulopathy and poorer oxygen delivery. Therefore, prehospital blood products best serve to improve initial hemodynamics and oxygen delivery when crystalloids would cause dilutional coagulopathy. They aren’t meant to replace crystalloids entirely, they don’t primarily reduce infection risk, and they’re not never used in trauma resuscitation.
