The Trauma patients are assigned MR# when they arrive and banded. Usually the request is for what we call a R-Pack(resuscitation) which includes 6 O red cells, 4 A liquid plasma and a platelet pheresis. Either a OR runner or ED Tech comes to pick up the blood product bringing a ADT label which has the patient's MR# , Doe name, and generic dob. The blood is issued in millennium documenting location, reason, transporter's employee number. The same log for issuing regular old blood products is use which has the patient's identifier, the two Techs issuing(reader and listener), the transporter's number(or full name) and the number of each product that is issued.
There is also a refrigerator between the 2 trauma bays that has 4 O+ red cells and 2 liquid plasmas. The nurses have to scan their badges(employee id) and enter the Patient's MR# to get access. There is a huge computer screen in the BB that shows that the refrigerator has been opened and we can see what got removed, who removed it and who it went to. However, I don't recommend this feature it is a pain in the behind ):
