Blood Transfusion (cont.)
Autologous Blood (using your own blood)
Pre-operative donation - donating your own blood before
surgery. The blood bank draws your blood and stores it until you need it
during or after surgery. This option is only for non-emergency (elective)
surgery. It has the advantage of eliminating or minimizing the need for
someone else's blood during and after surgery. The disadvantage is that
it requires advanced planning which may delay surgery. Some medical
conditions may prevent the pre-operative donation of blood
products.
Intra-operative autologous transfusion - recycling your blood
during surgery. Blood lost during surgery is filtered, and put
back into your body during surgery. This can be done in emergency and
elective surgeries. It has the advantage of eliminating or minimizing
the need for someone else's blood during surgery. Large amounts of blood can
be recycled. This process cannot be used if
cancer or infection is
present.
Post-operative autologous transfusion - recycling your blood
after surgery. Blood lost after surgery is collected, filtered
and returned to your body. This can be done in emergency and
elective surgeries. It has the advantage of eliminating or minimizing
the need for someone else's blood during surgery. This process can't be used
in patients where cancer or infection is present.
Hemodilution - donating your own blood during surgery.
Immediately before surgery, some of your blood is taken and
replaced with IV fluids. After surgery, your blood is filtered and returned
to you. This is done only for elective surgeries. This process dilutes your
own blood so you lose less concentrated blood during surgery. It has the
advantage of eliminating or minimizing the need for someone else's blood
during surgery. The disadvantage of this process is that only a
limited amount of blood can be removed, and certain medical conditions may prevent
hemodilution.
Apheresis - donating you own platelets and plasma. Before
surgery, your platelets and plasma, which help stop bleeding,
are withdrawn, filtered and returned to you when you need it later.
This can be done only for elective surgeries. This process may eliminate
the need for donor platelets and plasma, especially in high blood-loss
procedures. The disadvantage of this process is that some medical
conditions may prevent apheresis, and in actual practice it has limited
applications.
