  1. If the patient is bleeding out, chances are a transfusion reaction wouldn't even be noticed. Temperature, pulse/resp rates, etc are going to be all over the place in such an event, they might not even be making observations. I'd make sure that they know it's only to be used in exceptional circumstances, though. We have a massive transfusion protocol, and sometimes it seems they just activate it because it's easier than ordering blood products the usual way.
  2. Surely you should have enough O Neg blood for both of them? If you get a sample taken as soon as they arrive in hospital, and do a rapid group, you should only be giving a couple of O Negs anyway, and then switching to group specific.
  3. Does this mean we should be deferring ASD donors? After all, if plasmapheresis gets rid of the causative agent, then plasma donation must carry said agent...
  4. We have a "luggage label" tag with historical typings on the donor the unit came from, but if we actually need to care about the phenotype, we repeat it on a segment from that unit - just in case there's been a transcription error somewhere. It doesn't happen often, but more often than anyone likes.
  5. The only time we've ever run low on O Neg blood here, was when a patient was actually O Neg. That time we had to switch to O Pos while the patient was still hosing, and switched back once they got him/her (can't remember which) under control. In all other cases, at most the first 6 units were O Neg emergency blood, because we always demand a sample, and do a rapid (tube) forward group so we can start issuing group specific blood as soon as possible. And yeah, I don't think we have enough anti-D in stock to act as a chaser for even one unit of red cells if it's 500 IU/4 mLs...
  6. Sounds like a bad idea to me... donors might lie, or just not know. For example, a woman who lost her baby in the first few months might have formed antibodies, but if you ask her, even if she knew, she might not think it counts as having been pregnant. And unlikely as it seems, some people might be confused about whether they were given blood or not.
  7. Opaque ziplock bag, white for platelets and cryoprecipitate, green for FFP, and red for red cells.
  8. What's all this about giving O Pos to male patients? What if they start making anti-D and have a delayed transfusion reaction? Lucky for me I'm Rh(D) positive, but still... I demand that we men should have equal rights to O neg emergency blood! Edit: that being said, yeah, we only issue group specific blood if we have done a group on a current sample, otherwise we give O neg. To both genders
  9. Here in New Zealand, we would discard a unit if the antibody is strong enough. I don't work in that section of the blood service, so don't quote me, but from what I can find out, if the donor's sample is still reactive when diluted 1:50, then that's considered strong enough to discard. I guess the dilution is supposed to replicate the effect of packing the cells and taking the plasma off. So short answer to the OP is: sometimes
  10. We in New Zealand also require a new specimen before we'll change the details. We frequently have such changes, and get notified of them, and we put a comment in the computer system about the new name, but if we have to issue blood, then it always has the same details as the sample.
  11. The anti-A,B we use claims to be monoclonal, according to the bottle.
  12. I don't trust tube IAT very much any more, it seems like it's the test you do if you want a negative result I think that this patient might have been in danger of HTR if the prewarmed tube method had been used for Xmatch.
  13. We call it group checking, and we use instant spin tube technique. We test O units with anti-A,B, and all the other types with anti-A and anti-B, and additonally all Rh(D) negative units with anti-D. Weak D testing is not considered necessary. We didn't do any of that until we started electronic issuing, though, before that we did an instant spin crossmatch before all issues, and that was considered sufficient.
  14. No, but if it's a clinically significant antibody we continue to crossmatch antigen negative units. If it's something stoopid like anti-Le(a) we don't do either.
