400 bed level 1 trauma center which just changed the mtp protocol which seems to be working well. Previously, 4 red cells were sent out every 15-20 minutes with platelets, plasma and cryoprecipitate being sent base on lab results. As Scott mentioned above cumbersome and it seem like we couldn't keep up. Now every 15 minutes; 6 red cells, 6 plasmas (usually low titer A) and a platelet pheresis is dispensed. If the patient is an OB then a pooled cryo is also sent.
Part of the MTP start order includes lab orders that can be pulled 6 times during one start order. I don't have any idea how that works or what happens when the 6 orders are used up. But the orders are PT-INR, fibrinogen, platelet , ROTEM and H &H.
The other level 1 trauma center is using whole blood low titer O which they send out 6 units every 15 minutes. Which sounds heck of a luck easier than what we do. But they use a different blood supplier than we do (ours doesn't have low titer O). Also we are AABB accredited and there is some issue with AABB and giving low titer O whole blood to non-O patients.
