WOONOS IN ANIMALS /
They May Be Repaired-The Two
Methods in Use.
There are two principal methods by
which wounds are repaired. The first
these, and the more favorable of the
two, is the method termed by surgeons
healing by the first intention. Under |
favorable circumstances this takes place
N an incised wound when the cut sur
are brought carefully together and
in close contact after bleed
ing has ceased. The two surfaces then
become cemented together by the form
alton Of a thin intermediate layer of new
The other principal mode of
is healing by tine second inten-
ton. That is what takes place in large
wounds when the cut surfaces
can not be brought and maintained in
opposition, and it is the invariable
method of repair in punctured and lac
Grated wounds. Here the gap in the
becomes filed up by the growth
of new material taking place from the
bottom of the wound, while a new skin
grows inwards from the edge of the
wound. This skin, however, is not ex-
actly similar to the natural healthy skin
from which it extends, being thinner,
more delicate, and without any hair.
A third and much rarer process
of healing in wounds is what is
termed immediate union. In this,
it is said, the divided surfaces being
brought into accurate contact unite
without the intermediate growth of any
new texture. 1t is questionable if such
is really the case, but it is certain that
sometimes in small wounds the cut
surfaces when placed together unite sc
speedily and exactly that no scar is left.
In an incised wound treatment in the
first instance should be directed toward
favoring union by the first intention.
The essentials for this area sound
constitution on the part of the animal,
accurate and close contact with the
divided surface, and the absence of in.
fammation in the wound. Without
mans interference this process would
seldom or never ensue in the lower ami
mails. for in all wounds except the
smallest the cut surfaces cape apart
unless some means be adopted to keep
them together. The means commonly
adopted by surgeons for this purpose
are the application of strips of plaster
across the surface of the wound. or the
passing of sutures through its edge. In
adopting the former plan. a few strips,
according to the length of the wound.
should be applied at intervals; but the
entire surface should neve be entirely
covered by the plaster. The surfaces,
moreover, should not be brought to.
gether until bleeding has been arrested,
for should a clot of blood be efused into
the wound it would prevent healing
by this method. Sutures are simply
stitches used to tie or sew the edges OIL
surface of a wound together. They arc
used of various materials, such as thread,
horse-hair. cat-gut and wire. Nothing
further need be said about the applica-
ton of these. since their insertion into
a wound should always be left to d
veterinary surgeon. In a punctured or
a confused or lacerated wound, where
the surface can not be maintained to-
gether, or where inflammation ensues
in such a wound, then the treatment
must be that favorable to healing by
the second intention. Inflammation.
shown by redness, swelling and great
tenderness of the edges of the wound,
should be combatted by assiduous bath
ing with hot water. In a confused and
lacerated wound, such as ''broken
knees" particles of sand and other
foreign matter must be carefully and
lightly sponged from the surface; in
punctured wounds, or stabs, it must be
made certain that nothing remains in
the bottom of the wound; and in all
classes of wounds healing in this way
provision must be made to allow the
discharge from the wound a ready es.

ming from the surface upward to the
deepest part of the wound. The neces
sity for a free escape from a puncture6
wound is seen in the case of '.pricks'
of the feet. These are generally simple
in their effects if the track of the mai

Healthy wounds are seldom mucl
benefited by the application of lotion
or ointments. When the wound is o
small size it is best to leave it uncovered
and if it be in summer it may be smearet
with zinc ointment, or with forty part
of olive oil to one of carbolic acid. Ii
large wounds the surface should b.
