Platelet Transfusions


------------------------------------------------------------------------------

QUESTION:  I have a friend in the hospital who is getting transfusions, that
are not whole blood, but only some cells called "platelets".  Shouldn't he be
getting all the benefit that a real transfusion might give?

------------------------------------------------------------------------------

ANSWER:  The blood is an extremely complex substance, made up of many
components that serve different functions in maintaining the health of the
body.  Platelets are just one of these components, along with plasma, red
blood cells and white blood cells.  Individuals require transfusions of
any of these substances or a combination when symptoms indicate a drop in
the substance's normal level or to promote recovery from trauma or
surgery.
     When the problem is reduced clotting, platelets may be the answer.
Platelets enable the blood to coagulate, or clot.  Platelet disorders can be
either congenital or acquired; the result of either is prolonged bleeding
time, which can be life-endangering.  In addition, some drugs-- such as
aspirin, antidepressants or antibiotics like penicillin--can interfere with
the platelets' normal functioning .  The effect of these medications varies
from individual to individual.
     When excessive bleeding becomes life threatening, and the lack of
sufficient working platelets seem to be the cause of the problem, physicians
choose to replace only the blood element necessary to correct the condition,
in this case just platelets.  The rest of the blood elements and components
can then be used to help another needy patient, for example one who may profit
from receiving a transfusion of red cells.  All of this helps make our limited
blood reserves go further, to help all the patients we can.
