Our traumas are assigned MR#s before they are arrived and given a doe name, it is usually a name of a car (Mercedes, Doe). The sex is usually known and the dob is the same for all patients (100 yrs old). The computer system we use (Cerner Millennium) allows us the dispense the units with a exception flag telling us the unit isn't crossmatched ,do we want to override and why (we pick emergency). A transfusion tag is generated but the area which usually states compatible says uncrossmatched and across the blank area of the tag which usually has special attributes(irradiated) there is a statement saying "emergency dispensed, uncrossmatched.
