The storage and transport of blood products is a complicated issue. Packed Red Blood Cells (PRBCs) can be frozen for up to 10 years, but require several hours to thaw and warm to the point you can use them. Not very efficient if you need them for trauma care. They will not be able to identify the soldier until they arrive at the medical facility. That is if the soldier it transported to the one medical facility that has THIER blood. The PRBCs can't be carried by the soldier or the unit medic. They have to be used within a short timeframe after thawing and when warmed, can't be refrozen. PRBCs that have been at administration temp must be completely infused within four hours. After that, some vicious little nasties can grow in the blood and do bad things to the patient. New techniques are being developed, like freeze dried PRBCs, but the survivability of the red blood cells is 70-75%, depending on which study you read. Thawed PRBCs is 100%. The shelf life of refrigerated PRBCs is about 45 days. The theory is good and would work for continued care of the patient, but they have to keep some O-Negavie blood (Universal donor) blood on hand for emergent care.

Good information SGT Tim Soyars It doesn't sound as great an idea since you explained about blood. So, there's no way it could be used in the bush?

Not as expensive of the lives of our troops. But, I do understand. It's expensive and takes time.
