Do platelet transfusions require the same compatibility requirements of blood transfusions?My son is a 7 week old male. When he was 4 days old he needed a platelet transfusion. His blood type is O- and the donor was B+. From what I understand, an O- blood type can only receive O- donor blood. But what about platelet transfusions? His chart labeled the transfusion " Pheresed Platelets." He was in the NICU during this time and I don't really remember why he needed a platelet transfusion. He had two blood transfusions because his hemoglobin was 3.7 at birth but I don't see any tests results for platelets in his chart until the day after his platelet transfusion so I'm not sure if they were low before. I can bring this question up at his next doctor's appointment but I just wanted to get a sense first if it's normal/ok to give platelet transfusions from a B+ donor to an O- recipient.If we call platelet transfusion day Day 1 then his platelet levels were as follows:-Day 2: 58-Day 4: 40 and later 43-Day 5: 46-Day 6: 49-Day 9: 127They eventually got up into the 200s and most recently was in the 500s. We are working with hematology right now but I just thought I'd share the results in case it's pertinent.

Nope.It is preferred but not as big as a concern
3 year old male with unilateral swollen cervical lymph node, urgent?About 5 days ago I noticed that a lymph node on the right side of my sons neck was quite enlarged. When I palpate, it doesnt seem to hurt him, it is not mobile and feels more rubbery/hard. I would estimate it is 2-3cm across. He had Impetigo 2-3 weeks ago but it has been resolved for a week and he didnt have swollen lymph nodes at the time. He does not have any symptoms of illness currently and there is no one in the home sick. He is eating well, no recent weight loss. Is this something that should be evaluated within the next few days or is it fair to watch for 2-3 weeks to see if the lymph node goes back to the usual size? My son is 30 pounds, has controlled epilepsy and takes Keppra. He was followed by hematology for 1 year previously due to unexplained neutropenia. Has not had blood work in 8 months.
It likely won't return to its previous size, but will likely shrink down near that on the next few months (not weeks), if it doesn't or your concerned then make a non-urgent appointment with his doctor
