Depending on the
specific chemotherapy
authority used,
multiple myeloma
cases may
find that they're
listed to
suffer an autologous stem
cell transplant (stem
cells taken from the
case and
returned to the
same case-no
alternate parties are
involved.) The Arkansas Treatment is one
similar authority that combines chemotherapy with an autologous stem
cell transplant. To
collect stem
cells from one's
blood sluice, a
central venous catheter
generally needs to
be fitted in the jugular
tone at the
base of the
neck. This
composition describes the
details of this
procedure from a
case's
point of
view.
One might
anticipate that to
collect particular blood cells, they would
take blood out of one arm through an IV and
return it to the
other arm through another IV. That,
still, isn't
generally the case. The
process is
generally fulfilled by
fitting a
central venous catheter at the
base of the
neck into the jugular
tone. It sounds
much less
reasonable or
affable, but it turns out to
be a
fairly simple procedure.
Central venous catheters
have a plastic
base (at their
center), with several
plastic tubes coming out the
top of the
base which
end with lumens to which IV
lines can
fluently be connected. From the
bottom of the
base, one
larger straight plastic
tube extends
about 6 to 8
elevation to a
smooth phased tip.
Near examination shows a
hole at the tip and one or two
holes around the
circumference of the
tube about an
inch back of the tip. The
hole at the tip is
connected to one or
further lumens and the circumferential
holes are
connected to one or
further other lumens. A
typical catheter
fitted into a
case's
neck generally has three lumens-two
large and one
small.
The
design of the catheter allows one lumen to
be used to
draw blood out of the
tone, another lumen to
return blood to the
tone, and a third remains
free to
administer specifics if
needed.
Insertion of the catheter calls for the
phased tube to
be fitted through the
skin at the
base of the
neck and into the jugular
tone. The
tube also travels down (
outside) the
tone so the tip is
deposited in the
large tone right above the
entrance to the
heart. The insertion is
performed by a
croaker in an operating
suite at the
sanitarium.
The
typical process proceeds as follows After
arriving at the
collection room, the
case lies down in the
bed and the
bed is
wheeled to the operating
room where the
patient slides off the
bed and onto the operating
table.
Also, the nursing
staff begins
medications for the
procedure. The
croaker who'll
be fitting the catheter will
question the
case to
make sure both of them are at the
right place and that he's
performing the
proper procedure.
The operating
suite will
generally be equipped with several computer
observers above so the
croaker can
see, as he inserts the catheter, that he has
deposited its
business end at the
proper position at the
entrance to the
heart. The
case will
generally be given a nasal cannula with oxygen for breathing and a
blood pressure cuff will
be fastened to their arm to
allow dimension of
blood pressure during the
procedure.
Also the
case will
be covered with
wastes-the
only exposed area will
be the
area incontinently girding the
point where the catheter will
be fitted. When all
medications are
ready,
specifics are
generally administered to
make the
case relaxed (and
constantly sleepy). A
original anesthetic is
used to
numb the insertion
point. One
nanny will
be assigned to
keep a
close eye on the
case while others
help the
croaker. The
whole insertion
procedure only takes a
many twinkles.
Before you
know it, they will
be asking whether or not the you
remained awake throughout the
procedure, and would you please
slide back onto your
bed. Another
quick lift through the
hallways will
return the
case to the stem
cell collection room where the
recently fitted catheter will
be connected to the
collection machine and
incontinently put to
use.
There are two
major differences between a
central venous catheter and a PICC
line (a peripherally
fitted central catheter.) PICC
lines are
generally anchored in
place on the
case's arm by a
type fastened to the
skin with a
strong glue. Central venous catheters are
generally anchored in
place with several
aches. This may not
be egregious to the
case until a
nanny, who wants to
remove the catheter, says she needs to
first remove the
aches that are
anchoring it in
place.
The
other difference is that the
tubes of a
central venous catheter
have larger inside
compasses than those in a PICC
line. This allows
lesser volumes of
blood to
inflow fluently from the
case to the
collection machine, and
back again.
The stem
cell collection machine is an
instrument grounded on a
nonstop centrifuge. Since stem
cells are
small and light, when
spun in a centrifuge, they will
float to the
top where they can
fluently be separated and
collected. The
remainder of the
blood is
also returned nearly incontinently to the
case.
A
central venous catheter is
considered a"
temporary"
device-it can
remain in
place for at most 5
days. After that, it has to
be removed and stem
cell collection must
cease. In
utmost cases, sufficient
figures of stem
cells will
be collected within the five
days allowed. In some cases, one
day of
collection is sufficient. When
collection is
complete, the
central venous catheter can
be removed.
The
junking procedure simply requires the
anchoring aches to
be removed and the catheter to
be pulled out. No
anesthetic is
needed. Once the catheter is
out,
pressure will
be applied to the
entry spots for
about 10
twinkles. After that, the
tone and the
skin should
be sufficiently sealed that a
girth can
be applied and the
case can
be transferred on their
way.
Although one might
come anxious about
having a catheter
fitted into the jugular
tone at the
base of the
neck, this
procedure is a
common bone that isn't
painful nor should it
be stressed.
Numerous cases find that they were
anxious for no
good reason. The insertion
procedure goes
snappily and the
day spent collecting stem
cells is
generally a
long,
slow,
lazy,
relaxed day.
Watching Television,
reading,
sleeping,
working on the computer,
harkening to the radio,
eating and
drinking,etc., are all
allowed. The
only restriction is that as
long as the
tubes are
connected from the catheter to the
collection machine, the
case must
remain in the
bed. Collection ends
generally around 3P.M. at which
time the
case will
be released from the
collection machine and the
bed.
When it comes
time to
remove the catheter,
formerly again, it sounds worse than it
really is. It's a
effortless procedure that can
be performed by a transplant
nanny at the
cancer clinic.
The main recommendation for others who
need to
have this catheter
fitted, and
ultimately removed, is to not
fret about it. The
procedures go snappily and they're
fairly effortless. The
original shot of anesthetic on the
neck may
feel like a
freak sting, but
only for an
moment until the anesthetic
kicks in. After that, the
topmost vexation is that the
hanging lumens are awkwardly
deposited at the
base of the
neck.
Generally, the catheter isn't
painful and it's hardly noticeable. However, the
only way for the
case to
indeed see it's to
look in a
glass, If it's
deposited duly.
In the
big picture of
effects, the
central venous catheter is a
handy device to
use to
perform the stem
cell collection procedure. Hindsight suggests it isn't worth
getting anxious or
agitated about.
Other aspects of chemotherapy treatments can
be nastier than the
day (s)
spent collecting stem
cells.
