To
comparatively
analyze
maternal
and
fetal
factors
and
quality
markers
of
blood
samples
in
a
public
umbilical
cord
blood
bank.
Method:
This
is
a
cross-sectional
descriptive
study
that
revisited
458
records
of
donations
from
September
2009
to
March
2013
at
the
Hemocentro
de
Santa
Catarina.
The
means
of
markers
were
used
to
define
cutoff
points
for
the
quality
of
cord
blood.
Results:
Most
donations
came
from
women
with
ages
between
18
and
29
years
(62.8%),
gestational
age
≥
40
weeks
(55.2%),
vaginal
delivery
(51.3%),
primiparous
(41.4%),
and
with
male
newborns
(54.4%)
weighing
between
3000
and
3499
g
(41.8%).
The
volume
of
the
dona-
tions
ranged
from
71.6
to
275.2
mL,
the
total
nucleated
cell
count
ranged
from
4.77
×
10
8
to
31.0
×
10
8
cells
and
CD34
+
cells
ranged
from
0.05
to
1.23%.
There
were
statistically
significant
differences
in
the
volume
with
respect
to
gestation
age
>
38
weeks
(
p
-value
=
0.001),
cesarean
section
(
p
-value
<
0.001)
and
birth
weight
>
3500
g
(
p
-value
<
0.001).
The
total
nucleated
cell
count
was
positively
affected
by
cesarean
section
(
p
-value
=
0.022)
and
birth
weight
>
3500
g
(
p
-value
<
0.001).
There
was
no
statistically
significant
difference
between
the
variables
and
the
percentage
of
CD34
+
cells.
Conclusions:
Delivery
route
and
birth
weight
influence
the
volume
of
cord
blood
and
the
total
nucleated
cell
count.
Gestational
age
influences
only
the
volume
of
cord
blood.
