Platelets
are tiny, copuscular elements in the
blood that are critical to the control
of bleeding. Many patients develop platelet
shortages from illness, and others do
as a result of chemotherapy, radiation
or cardiac surgery. In order to treat
all these groups, it is necessary to
provide "platelet transfusions."
Years ago, the only way to collect
enough platelets for a transfusion was
to take blood donations from many donors,
separate the platelets from the other
blood cells, and combine the platelets
into one transfusion.Today, "blood
cell separators" allow collection
of enough platelets for transfusion
from a single donor. In a process called
"apheresis," blood is drawn
from the donor into an instrument that
separates the blood into separate portions
by centrifugation. Platelets can be
recovered, while the rest of the blood
is returned to the donor.
Though the procedure takes somewhat
more time than whole blood donation,
it is a simple, safe process. Because
the body starts replenishing platelets
immediately after donation, a donor's
platelets are completely replenished
within about 48 hours. This means that
those so-inclined can donate platelets
up to two dozen times per year.(At QueensBloodDonor,
an individual may donate again after
72 hours.)
