I have a quick question: Is there a limit to how many times a unit of rbc's can be sent via pneumatic tube? I sent a unit to the floor. The nurse called me within 5 minutes and apparently the IV had infiltrated and she couldn't hang the blood. I had her send it back to me as it had not been spiked. The temp was fine and I put it back in the fridge. I could not find any documentation in our procedures about it and looked on the net etc.. My gut feeling was that I would err on the side of caution and when they requested it again the nurse had no problem with coming to the lab to pick it up (we are in a different building than the hospital). Most of my coworkers thought I was crazy (not disputing that) so I wanted to check with you fine folks! Haven't been online in a while and miss all of the talk! Hello to Malcolm Needs! (I am sure he is still about)!
