Embalming
Prepare two ligatures, make the incision in the vein and pass gently
the basilic drainage tube upward toward the heart. Either a steel or
rubber tube may be used. If the flexible rubber tube is used, it will
find its way to the right auricle of the heart, its course is through
the basilic, axillary, sub-clavian, innominate, superior vena cava, to
the right auricle. Either the aspiration or the drainage methods may be
used. If these fail try the displacement method.
The use of the basilic for the removal of blood is fast disappearing
from general practice. Larger veins can be used, which will always
insure greater success.
=The Removal of Blood from the Internal Jugular Vein.=—The internal
jugular vein is the largest tributary vein in the body, and accompanies
the carotid artery. The operator will cut through the skin at a point
from one half inch above the clavicle or collar bone and in the valley
formed by the sterno-mastoid muscle to the outside and the muscles
of the wind pipe to the inside, cut upward making the perpendicular
incision. Raise both the artery and the vein according to the usual
method. It seems best to raise the artery and the vein together, and
by so doing this will tend to give added strength to the vein which is
very large but has quite thin walls.
Direct the hook around the vein first then around the artery toward
the wind pipe or trachea, raise both to the surface, place on the
bone separator, and remove the sheaths. Use any of the drainage tubes.
Insert the vein drainage tube and the arterial tube, the point of both
tubes being directed toward the heart. The injection should be made
slowly, which will cause the blood to flow from the vein through the
tube and into the blood bottle.
This vein is not as much used as the axillary or the femoral for the
removal of blood.
It is true that it is very close to the center of circulation and a
gateway for the blood from the face. The chief disadvantage is that the
vein lies quite deep, is very large and has such thin walls, that it is
almost impossible to raise it without a rupture.
About one-thirteenth of the body's weight is calculated to be blood.
Granting for the sake of argument that the average body that we
would desire to draw blood from would weigh 208 pounds, then that
average body would contain 16 pounds of blood. One pound of blood is
practically equal to one pint, making the average body to contain about
16 pints of blood.
After death about one-fourth of the blood of the body is found in the
portal system. The portal system has capillaries at both ends so that
it is impossible to draw this blood.
After death about one-fourth of the blood of the body is found in the
tiny capillaries and tissues, blood which by the ordinary methods used
today the embalmer is unable to draw.
After death about one-fourth of the blood of the body is found in the
azygos system, and points dependent in the body, which blood, too, it
is impossible to draw.
