Hi Mabel, welcome to the Pacific Northwest! I might be able to help you. Our blood supplier is 4 hours away and they have worked with us as our NICU was implemented. Our NICU is not the highest level...I think we are level 2 at the moment. We transfuse very few infants at this point but when we do we order what PSBC calls an assigned aliquot...they dedicate one AS-5 unit, leukoreduced unit to the infant then divide into 8 pedi packs. When they ship they irradiate the number of packs we request. Our neonatologist [OHSU based] will use an irradiated AS=5 unit for up to 28 days. They know how to manage the potassium problem clinically so are not concerned...if it is a small volume transfusion..most are. We would never give out of group plasma for platelets ...if we didn't have plasma compatible platelets we can get from across the river. The only thing you could do is as you have said...medical decision at the bedside unless the problem was known before delivery and you had some time. We keep AB FFP from same donor and AB cryo. Chartmed filters are great. We don't have a sterile docker....for us it isn't practical at this point because we have so few transfusions, the maintenance, QC, training would not be worth it..I wouldn't be able to keep everyone competent on its use. Using the pedi packs precludes the need for that at the moment. When volume increases it will be more practical.
