while the calf, owing to large size or wrong presentation, was detained in
the womb, and the continued dilatation of the womb in the absence of the
fetal membranes led to a flow of blood which accumulated in clots around
the calf. Other causes are laceration of the cotyledons of the womb, or
from an antecedent inflammation of the placenta, and the unnatural adhesion
of the membranes to the womb, which bleeds when the two are torn apart.
Weakness of the womb from overdistention, as in dropsy, twins, etc., is not
without its influence. Finally, eversion of the womb (casting the withers)
is an occasional cause of flooding. The trouble is only too evident when
the blood flows from the external passages in drops or in a fine stream.
When it is retained in the cavity of the womb, however, it may remain
unsuspected until it has rendered the animal almost bloodless. The symptoms
in such case are paleness of the eyes, nose, mouth, and of the lips of the
vulva, a weak, rapid pulse, violent and perhaps loud beating of the heart
(palpitations), sunken, staring eyes, coldness of the skin, ears, horns,
and limbs, perspiration, weakness in standing, staggering gait, and,
finally, inability to rise, and death in convulsions. If these symptoms are
seen, the oiled hand should be introduced into the womb, which will be
found open and flaccid and containing large blood clots.
_Treatment._--Treatment consists in the removal of the fetal membranes and
blood clots from the womb (which will not contract while they are present),
the dashing of cold water on the loins, right flank, and vulva, and if
these measures fail, the injection of cold water into the womb through a
rubber tube furnished with a funnel. In obstinate cases a good-sized sponge
soaked in tincture of muriate of iron should be introduced into the womb
and firmly squeezed, so as to bring the iron into contact with the bleeding
surface. This is at once an astringent and a coagulant for the blood,
besides stimulating the womb to contraction. In the absence of this agent
astringents (solution of copperas, alum, tannic acid, or acetate of lead)
may be thrown into the womb, and one-half-dram doses of acetate of lead may
be given by the mouth, or 1 ounce powdered ergot of rye may be given in
gruel. When nothing else is at hand, an injection of oil of turpentine will
sometimes promptly check the bleeding.
EVERSION OF THE WOMB (CASTING THE WITHERS).
Like flooding, this is the result of failure of the womb to contract after
calving. If that organ contracts naturally, the afterbirth is expelled, the
internal cavity of the womb is nearly closed, and the mouth of the organ
becomes so narrow that the hand can not be forced through, much less the
whole mass of the matrix. When, however, it fails to contract, the closed
end of one of the horns may fall into its open internal cavity, and under
the compression of the adjacent intestines, and the straining and
contraction of the abdominal walls, it is forced farther and farther, until
the whole organ is turned outside in, slides back through the vagina, and
hangs from the vulva. The womb can be instantly distinguished from the
protruding vagina or bladder by the presence, over its whole surface, of 50
to 100 mushroomlike bodies (cotyledons), each 2 to 3 inches in diameter,
and attached by a narrow neck. (Pls. XII, XIII.) When fully everted, it is
further recognizable by a large, undivided body hanging from the vulva, and
two horns or divisions which hang down toward the hocks. In the imperfect
eversions the body of the womb may be present with two depressions leading
into the two horns. In the cases of some standing the organ has become
inflamed and gorged with blood until it is as large as a bushel basket, its
surface has a dark-red, bloodlike hue, and tears and bleeds on the
slightest touch. Still later lacerations, raw sores, and even gangrene are
shown in the mass. At the moment of protrusion the general health is not
altered, but soon the inflammation and fever with the violent and continued
straining induce exhaustion, and the cow lies down, making no attempt to
rise.
_Treatment._--Treatment varies somewhat, according to the degree of the
eversion. In partial eversion, with the womb protruding only slightly from
the vulva and the cow standing, let an assistant pinch the back to prevent
straining while the operator pushes his closed fist into the center of the
mass and carries it back through the vagina, assisting in returning the
surrounding parts by the other hand. In more complete eversion, but with
the womb as yet of its natural bulk and consistency and the cow standing,
straining being checked by pinching the back, a sheet is held by two men so
as to sustain the everted womb and raise it to the level of the vulva. It
is now sponged clean with cold water, the cold being useful in driving out
the blood and reducing the bulk, and finally it may be sponged over with
laudanum or with a weak solution of carbolic acid (1 dram to 1 quart
water).
The closed fist may now be planted in the rounded end of the largest horn
and pushed on so as to turn it back within itself and carry it on through
the vagina, the other hand being used meanwhile to assist in the inversion
and in pushing the different masses in succession within the lips of the
vulva. In case of failure, resort should be had at once to a plan which I
have successfully followed for many years. Take a long linen or cotton
bandage, 5 or 6 inches wide, and wind it around the protruding womb as
tightly as it can be drawn, beginning at the free end and gradually
covering the entire mass up to the vulva. By this means the greater part of
the blood will be forced out of the organ and its bulk greatly reduced, so
that its reduction is much facilitated. An additional advantage is found in
the protection given to the womb by its investing bandage while it is being
pushed forward into the vagina and abdomen. In manipulating the exposed
womb there is always danger of laceration, but when the organ is covered
with a sheet it is next to impossible to tear it. The subsequent
manipulation is as in the other case, by pushing the blind end forward
within itself with the closed fist and carrying this on through the vagina
into the abdomen with the constant assistance of the other hand. Often it
will be found convenient to use the edge of the left hand to push the outer
part of the protruding mass inside the lips of the vulva, while the right
hand and arm are carrying the central portions forward through the vagina.
An intelligent assistant, pushing with the palms of both hands on the outer
portion of the mass, will also afford material assistance. As the womb is
turned within itself the wrapping bandage will gradually loosen, but once
the great mass has entered the passages it is easy to compel the rest to
follow, and the compression by the bandage is no longer so important. When
the womb is fully replaced the bandage is left in its interior in a series
of loose folds, and can be easily withdrawn. It is well to move the hand
from side to side to insure that the two horns of the womb are fully
extended and on about the same level before withdrawing the arm and
applying a truss.
When the womb has been long everted and is gorged with blood, inflamed, and
friable there is often the additional disadvantage that the animal is
unable or unwilling to rise. When lying down the straining can not be
controlled so effectually, and, even in the absence of straining, the
compression of the belly is so great as to prove a serious obstacle to
reduction. The straining may be checked by 2 or 3 ounces of laudanum or 2
ounces of chloral hydrate, or by inhalation of chloroform to insensibility,
and then by raising the hind parts on straw bundles the gravitation of the
abdominal organs forward may be made to lessen the resistance. If not
successful in this way, the cow may be further turned on her back, and if
return is still impossible, the hind limbs may be tied together and drawn
up to a beam overhead by the aid of a pulley. In this position, in place of
the pressure backward of the bowels proving a hindrance, their gravitation
forward proves a most material help to reduction. In seeking to return the
womb the sponging with ice-cold water, raising on a sheet, and wrapping in
a tight bandage should be resorted to. Another method which is especially
commendable in these inflamed conditions of the womb is to bring a piece of
linen sheet, 30 by 36 inches, under the womb, with its anterior border
close up to the vulva, then turn the posterior border upward and forward
over the organ, and cross the two ends over this and over each other above.
The ends of the sheet are steadily drawn, so as to tighten its hold on the
womb, which is thus held on the level of the vulva or above, and cold water
is constantly poured upon the mass. The reduction is further sought by
compression of the mass with the palms applied outside the sheet. Fifteen
or twenty minutes are usually sufficient to cause the return of the womb,
provided straining is prevented by pinching the back, or otherwise.
In old and aggravated cases, with the womb torn, bruised, or even
gangrenous, the only resort is to amputate the entire mass. This is done by
tying a strong, waxed cord around the protruding mass close to the vulva,
winding the cord around pieces of wood, so as to draw it as tightly as
possible, cutting off the organ below this ligature, tying a thread on any
artery that may still bleed, and returning the stump well into the vagina.
Retention of the returned womb is the next point, and is most easily
accomplished by a rope truss. Take two ropes, each about 18 feet long and
an inch in thickness. Double each rope at its middle, and lay the one above
the other at the bend, so as to form an ovoid of about 8 inches in its long
diameter. Twist each end of the one rope twice around the other, so that
this ovoid will remain when they are drawn tight. (Pls. XXII and XXIII.)
Tie a strap or rope around the back part of the neck and a surcingle around
the body. Place the rope truss on the animal so that the ovoid ring will
surround the vulva, the two ascending ropes on the right and left of the
tail and the two descending ones down inside the thighs on the right and
left of the udder. These descending ropes are carried forward on the sides
of the body and tied to the surcingle and to the neck collar. The ascending
ropes proceed forward on the middle of the back, twisting over each other,
and are tied to the surcingle and collar. The upper and lower ropes are
drawn so tightly that the rope ring is made to press firmly all around the
vulva without risk of displacement. This should be worn for several days,
until the womb shall have closed and all risk of further eversion is at an
end. Variations of this device are found in the use of a narrow triangle of
iron applied around the vulva and fixed by a similar arrangement of ropes,
surcingle, and collar (Pl. XXIII, fig. 3), a common crupper similarly held
around the vulva (Pl. XXII, fig. 1), stitches through the vulva, and wire
inserted through the skin on the two hips (Pl. XXIII, fig. 2), so that they
will cross behind the vulva; also pessaries of various kinds should be
inserted into the vagina. None of these devices, however, present any
advantage over the simple and comparatively painless rope truss described
above. Such additional precautions as keeping the cow in a stall higher
behind than in front, and seeing that the diet is slightly laxative and
nonstimulating may be named. If straining is persistent, ounce doses of
laudanum may be used twice a day, and the same may be injected into the
vagina.
If the womb has been cut off, injections of a solution of a teaspoonful of
carbolic acid in a quart of water should be used daily, or more frequently,
until the discharge ceases.
EVERSION OF THE BLADDER.
A genuine eversion of the bladder is almost unknown in the cow, owing to
the extreme narrowness of its mouth. The protrusion of the bladder,
however, through a laceration sustained in calving, in the floor of the
vagina and its subsequent protrusion through the vulva, is sometimes met
with. In this case the protruding bladder contains urine; this can never be
the case in a real eversion, in which the inner surface of the bladder and
the openings of the ureters are both exposed outside the vulva. The
presence of a bag containing water, which is connected with the floor of
the vagina, will serve to identify this condition. If the position of the
bladder in the vulva renders it impracticable to pass a catheter to draw
off the urine, pierce the organ with the nozzle of a hypodermic syringe, or
even a very small trocar and cannula, and draw off the water, when it will
be found an easy matter to return the bladder to its place. The rent in the
vagina can be stitched up, but as there would be risk in any subsequent
calving it is best to prepare the cow for the butcher.
RUPTURE OF THE BLADDER.
This has been known to occur in protracted parturition when the fetus
finally passed while the bladder was full. The symptoms are those of
complete suppression of urine and tenderness of the abdomen, with a steady
accumulation of liquid, and fluctuation on handling its lower part. If the
hand is introduced into the vagina it is felt to be hot and tender, and
perhaps slightly swollen along its floor. As a final test, if the lower,
fluctuating part of the abdomen is punctured with a hypodermic needle, a
straw-colored liquid of a urinous odor flows out. The condition has been
considered as past hope. The only chance for recovery would be in opening
the abdomen, evacuating the liquid, and stitching up the rent in the
bladder, but at such a season, and with inflammation already started, there
would be little to hope for.
RUPTURE OF THE WOMB.
When the womb has been rendered friable by disease rupture may occur in the
course of the labor, but much more frequently it occurs from violence
sustained in attempting assistance in difficult parturition. It is also
liable to occur during eversion of the organ through efforts to replace it.
If it happens while the calf is still in the womb, it will usually bleed
freely and continuously until the fetus has been extracted, so that the
womb can contract on itself and expel its excess of blood. Another danger
is that in case of a large rent the calf may escape into the cavity of the
abdomen and parturition become impossible. Still another danger is that of
the introduction of septic germs and the setting up of a fatal inflammation
of the lining membrane of the belly (peritoneum). Still another is the
escape of the small intestine through the rent and on through the vagina
and vulva, so as to protrude externally and receive perhaps fatal injuries.
In case of rupture before calving, that act should be completed as rapidly
and carefully as possible, the fetal membranes removed, and the contraction
of the womb sought by dashing cold water on the loins, the right flank, or
the vulva. If the calf has escaped into the abdomen and can not be brought
through the natural channels, it may be permissible to fix the animal and
extract it through the side, as in the CÊsarian section. If the laceration
has happened during eversion of the womb it is usually less redoubtable,
because the womb contracts more readily under the stimulus of the cold air
so recently applied. In case the abdomen has been laid open it is well to
stitch up the rent, but if not, it should be left to nature, and will often
heal satisfactorily, the cow even breeding successfully in after years.
Rupture of the floor of the vagina has been already referred to as allowing
the protrusion of the bladder. Laceration of the roof of this passage is
also met with as the result of deviations of the hind limbs and feet upward
when the calf lies on its back. In some such cases the opening passes clear
into the rectum, or the foot may even pass out through the anus, so that
that opening and the vulva are laid open into one.
Simple, superficial lacerations of the vaginal walls are not usually
serious, and heal readily unless septic inflammation sets in, in which case
the cow is liable to perish. They may be treated with soothing and
antiseptic injections, such as carbolic acid, 1 dram; water, 1 quart.
The more serious injuries depend on the complications. Rupture of the
anterior part of the canal, close to the mouth of the womb, may lead to the
introduction of infecting germs into the cavity of the abdomen, or
protrusion of the bowel through the rent and externally, either of which
may prove fatal. If both these conditions are escaped the wound may heal
spontaneously. Rupture into the bladder may lead to nothing worse than a
constant dribbling of the urine from the vulva. The cow should be fattened
if she survives. Rupture into the rectum will entail a constant escape of
feces through the vulva, and, of course, the same condition exists when the
anus as well has been torn open. I have successfully sewed up an opening of
this kind in the mare, but in the case of the cow it is probably better to
prepare her for the butcher.
CLOTS OF BLOOD IN THE WALLS OF THE VAGINA.
During calving the vagina may be bruised so as to cause escape of blood
beneath the mucous membrane and its coagulation into large bulging clots.
The vulva may appear swollen, and on separating its lips the mucous
membrane of the vagina is seen to be raised into irregular rounded
swellings of a dark-blue or black color, and which pit on pressure of the
finger. If the accumulation of blood is not extensive it may be reabsorbed,
but if abundant it may lead to irritation and dangerous inflammation, and
should be incised with a lancet and the clots cleared out. The wounds may
then be sponged twice a day with a lotion made with 1 dram sulphate of
zinc, 1 dram carbolic acid, and 1 quart water.
RETAINED AFTERBIRTH.
The cow, of all our domestic animals, is especially subject to this
accident. This may be partly accounted for by the firm connections
established through the fifty to one hundred cotyledons (Pl. XIII, fig. 2)
in which the fetal membranes dovetail with the follicles of the womb. It is
also most liable to occur after abortion, in which preparation has not been
made by fatty degeneration for the severance of these close connections. In
the occurrence of inflammation, causing the formation of new tissue between
the membranes and the womb, we find the occasion of unnaturally firm
adhesions which prevent the spontaneous detachment of the membranes. Again,
in low conditions of health and an imperfect power of contraction we find a
potent cause of retention, the general debility showing particularly in the
indisposition of the womb to contract, after calving, with sufficient
energy to expel the afterbirth. Hence we find the condition common with
insufficient or innutritious feed, and in years or localities in which the
fodder has suffered from weather. Ergoted, smutty, or musty fodder (Pl. V),
by causing abortion, is a frequent cause of retention. Old cows are more
subject than young ones, probably because of diminishing vigor. A temporary
retention is sometimes owing to a too rapid closure of the neck of the womb
after calving, causing strangulation and imprisonment of the membranes.
Conditions favoring this are the drinking of cold (iced) water, the eating

_Symptoms._--The symptoms of retention of the afterbirth are usually only
