We currently use Saf-T-Vue 6 temperature monitoring devices on all packed cells which go into validated coolers to be transported to the ED during a trauma or massive transfusion. We apply the devices on two O-Neg and 2 O-Pos stored units (for a regular trauma), but activate them when the unit is issued. The devices can remain on the unit indefinitely as long as the indicator is white, but if the indicator turns red at any time, then the unit must be discarded. For those of you who have a Massive Transfusion Protocol, do you apply temperature monitoring devices on all of the packed cells going out in coolers? At times, when we get a bad MT, we may be issuing packages containing 6 red cells, 6 FFP and 1 plt so fast that sometimes the techs do not get the stickers on the red cell units in time. I am trying to avoid placing devices on all the Oneg and many of the Opos units ahead of time, which would mean buying many boxes of Saf-T-Vue stickers. How have you dealt with this issue during a Massive Transfusion?
