Posted March 28, 200817 yr comment_7266 At what age do you allow ABO incompatible Apheresis Single Donor Platelets? Presently we use 10 years as the cut off, all children under 10 must receive ABO compatible, if it's not available we wash(!) the Platelet. We don't want to start concentrating and removing the plasma. However, if someone out there has a procedure could you share it?
March 31, 200817 yr comment_7287 HiI'll share an SOP - send me an email and I'll attach it to my reply.
April 2, 200817 yr Author comment_7309 That would be great if you would share your SOP! My email is debra.charland@inova.org
April 2, 200817 yr comment_7321 I would wonder if a certain body weight might be more meaningful. Children, especially sick ones, can have a huge difference in body size (and therefore blood volume)--or is weight too hard to consistently get in a timely fashion? It is recorded in our computer system once it is established.

May 12, 200916 yr comment_13437 We have validated a washed apheresis platelet procedure on our Cobe 2991 Cell Processor, using 0.9% NaCl in the V2 position. The program is BASICALLY as follows:Super out Rate = 100 mL/minAgitate Time = 100 SecSuper Out Volume = 425 mLCycle 1: Spin Time = 10 min, V2Cycle 2: Spin Time = 5 Min, V2Cycle 3: Spin Time = 5 min, change Super Out volume to 550 mLFor the Cycle 1 spin timer, if you have a programmable board, you can just set the time to 10 minutes. If you have the old peg-board and dial model, then you have to set the timer to 5 minuts and start with the auto/manual switch set to "Manual". Set a timer for 5 minutes, then press Start/Spin. When your timer goes off, flip the auto/manual switch back to "Auto", and the program will start.
May 13, 200916 yr comment_13479 Our policy is to use ABO identical or compatible up to and including 16 years of age.......If not abailable, we will either wash or volume reduce. Most techs will choose to wash.
May 13, 200916 yr comment_13497 We make every effort to ABO match or plasma compatible for all of our platelet transfusions. Since we are giving pheresis platelets, giving out of type would be like giving a unit of plasma out of type. Most people would not even consider doing that, but do not hesitate to give out of type platelets.

May 22, 200916 yr comment_13769 Hi Mobea, can you send me a copy of the Platelet Transfusion in Children SOP also? My email is: chengchunkwok@yahoo.comThanks.CK Cheng, MSc, SBB(ASCP), CQA(ASQ)Hong KongMay 22, 2009
