What is anemia?
Anemia is having too few red blood cells. Red blood
cells carry oxygen to the body.
How do the doctors know if
my baby has anemia?
Two laboratory tests, HEMATOCRIT and HEMOGLOBIN,
are used to determine red blood cells in blood. The value for the hematocrit is
usually about three times larger than the hemoglobin.
How do my baby's doctors
know if my baby is making blood?
A blood test called the RETICULOCYTE COUNT measures
the percent of newly made red blood cells.
Why do premature babies get
anemic?
They become anemic because:
-
their red blood cells have a shorter life
than red blood cells of adults. This may be exaggerated if the baby's
blood type is different than the mother's.
-
they make few new red blood cells in the
first few weeks of life
-
blood is taken from the baby to do necessary
laboratory tests. This is the most common reason for premature infants to
need transfusions or treatment for anemia.
How is anemia treated?
-
Anemia is usually treated by transfusions of
red blood cells obtained from the blood bank. This is the only way to
increase the number of red blood cells rapidly.
-
Anemia can also be treated by
erythropoietin.
This is a drug similar to the substance the body normally produces to
increase the number of red blood cells. It works slowly over days to
weeks. It is not useful if the anemia needs to be treated more rapidly.
-
Anemia does not always need to be treated if
it is not severe and if the baby is not sick or having frequent laboratory
tests. Eventually the baby will make more red blood cells.
-
Later, as the baby grows, s/he may need an
additional source of iron. This may be an iron fortified formula, vitamins
with iron, or iron drops. Iron is needed by the body to make red blood
cells.
Can my baby have my blood
for transfusions?
-
women who have recently given birth are not
usually considered for blood donation because they have already lost blood
with the delivery of the baby.
-
blood for a baby must be from someone with a
compatible blood type and it must pass several screens for exposures to
certain viruses. The majority of potential donors are not acceptable for
these reasons. Even if you give blood regularly, your blood may not be
acceptable for your baby.
-
if you are interested in finding out if you,
a friend, or a relative are an acceptable donor, ask your baby's doctor if
the hospital has a directed donor program.
How many blood transfusions
will my baby need?
That depends on how small and how sick your baby
is. Very tiny infants with respiratory problems may require transfusions as
often as once a day. Larger, healthy premature babies may never need a
transfusion.
