I was all set to bank my own blood but could not put it together in the time available. Doctors then said it was probably not necessary as they salvage my own blood.
Just to confirm what Lyn mentioned, it seems to be standard procedure at most hospitals. At our hospital the cardiovascular perfusion equipment (heart/lung bypass pump) is owned and operated by a private person and his account shows the salvaging of blood and the use of the autotransfusion cell washing device. It seems to be part and parcel of the bypass pump equipment....
BUT I had such a platelet problem in the ICU that I still needed 2 units from the general bloodbank. Not very happy about having received foreign blood but at that stage had no choice, in fact I was still totally sedated and was only told afterwards.
Did you get just platelets? IF so for the most part, even IF you donated blood, you would still have needed other people's platelets. The amount of platelets from 1 unit of blood, is such a small amount, they usually give bags of "pooled platelets",that are (i forget the exact number now) all the platelets from 6-10 donor units of blood. So even if they took the platelets from your blood it would have been a small amount of the platelets you got.
There is another kind of platelets call single donor platelet, but that is quite involved process, where they take blood out of a donor into a machine that removes the platelets only and replace the rest of your blood. This way you get all the platelets from 1 donor. The problem w/ single donor platelets and why you can't donate that for yourself, is they have a very short shelf life and have to be thrown out after 5 days. It takes your body about 2 weeks to replace that many platelets, and You certainly don't want to go into heart surgery with very low platelets.
