I see discussions about the 30 min or 10 degree dilemma, but not this particular issue. I'm not talking about if the unit has been spiked, this it is definitely discarded. If the unit is issued to the floor and returns say 15 mintues later, the unit is 11 degrees, we change expiration to 4 hours from dispense and quaranteen the unit for only that patient. Floor can re-request the unit as long and the transfusion can be completed within the 4 hour time frame from original dispense. The unit never goes back to the general inventory. They have 4 hours to complete the transfusion.
