TREATMENT OF INFLAMMATION AND FEVER.

Treatment will be guided very largely by the type of the attendant

fever. If that is of a high type, with a hard, full, rapid pulse, bright

red mucous membranes, a clear eye, and well sustained strength in a

strong, vigorous animal, what is known as antiphlogistic (depleting,

depressing) treatment is admissible at the outset. But in many cases

with a low type of fever, a weak, rapid pulse, pallid, yellow, or livid

mucous membranes, a coated tongue, a dull or sunken eye, much depression

and prostration, swaying on the limbs in walking, pendant head, ears,

eyelids and lips, and varying and irregular temperature of the limbs,

etc., such measures are forbidden from the first, and tonics and

stimulants are demanded from the outset. Between the two extremes there

are many grades, which demand a judiciously adjusted intermediate

treatment. The general principles only of each characteristic form of

treatment can be here formulated, it being understood that no two cases

can be most advantageously treated in precisely the same way, but that

according to its special grade each case will demand its own specific

management applied according to the skill of the physician.

_Regimen._ An antiphlogistic diet will consist in a moderate or very

sparing amount of non-stimulating food of easy digestion (wheat bran or

oil meal in warm, sloppy mash, carrots, turnips, beets, potatoes,

apples, pumpkins; fresh, tender, green grass or in winter a little

scalded hay, may be taken as examples). _Ruminants_ should have no food

necessitating chewing of the cud; thus the roots, etc., should be pulped

or boiled, and hay and even grass must be interdicted until rumination

is re-established. When food is absolutely refused for days in

succession well-boiled gruels of oatmeal, barley-meal, linseed meal,

bran, etc., may be given from a bottle or by injection. _Dogs_ and

_cats_ should have only vegetable mush (unbolted flour, barley, or

oatmeal) with just enough beef-juice to tempt the animal to eat a

little. Milk with an admixture of oxide of magnesia, or even lime water

is often at once palatable and cooling. _Drink_ should be pure water,

cool, if kept constantly fresh before the animal, but warmed to

something less than tepid if supplied only at long intervals, so that

the thirsty patient is not tempted to drink to excess and chill himself.

_Rest_ in a clean, well-aired building, free from draughts of cold air

and with a southern exposure, is desirable, especially in winter. The

best temperature is usually sixty degrees to seventy degrees, especially

in inflammations in the chest, and extremes of temperature are to be

avoided. _Clothing_ will depend on the weather. In warm weather it may

be often discarded, while in winter it should always be sufficient to

obviate the access of _chill_ and consequent aggravation of the disease.

Whenever the atmosphere can be kept warm only at the expense of impurity

it is better to secure the comfort of the patient by the requisite

clothing than to subject him to impure air. As the extremities are the

first to suffer from cold, loose flannel bandages to the limbs are often

imperative.

_Remedies._ _General bleeding_, a great resort of our fore-fathers, has

been long all but discarded from modern practice. Today it is rarely

resorted to, except to save from an urgent and extreme danger, as in the

plethoric cow merging into parturient apoplexy, or the fat and

overdriven horse, gasping for breath and life, in general acute

congestion of the lungs. There are other cases of extensive acute and

dangerous congestions, especially in a strong, vigorous, and plethoric

patient, in which general bleeding in beneficial in warding off

threatened death; but sound, discriminating judgment is necessary to its

safe employment. When resorted to at all, the blood should be drawn from

a large orifice, in a full stream, to secure the desired depressant

effect with the smallest loss of blood, and the patient should be kept

especially quiet and apart from all excitement which would tend to

counteract the sedative action.

_Local bleeding_ is more extensively applicable than _general_, as it

usually effects the same purpose without the permanently weakening

effect. It acts in two ways, first, by emptying and contracting the

vessels in the skin over the inflamed organ, it solicits a sympathetic

contraction of the capillary vessels in that organ itself, and thus

inaugurates a progress toward recovery; and second, by so much as it

draws blood to the surface it diminishes the blood pressure on the

deeper inflamed organ, and affords a better opportunity for the

restoration of the healthy circulation and function. Local bleeding may

be practiced by simple scarification or leeches, or better, by cupping

with or without scarification. To apply leeches, the skin must first be

shaved. To cup, it must at least be greased. As a cup, an ordinary large

drinking-glass may be used, the air contained in it being driven out by

a lighted taper, and then the taper being withdrawn, the mouth of the

cup is instantly and accurately applied on the skin and held there,

until, as it cools, it draws up the skin within it and clings like a

sucker. A number of these may be applied according to the extent of the

inflammation, and, if desired, they may be removed, the part scarified,

and the cup reapplied. The cupping usually effects more than a mere

local attraction of blood; it very commonly causes a free circulation in

the whole skin, a generally diffused warmth, and even perspiration. Thus

we may secure the derivation of blood from the inflamed part, the

cooling of a large mass of blood in the extensive cutaneous circulation,

the cooling of the entire system by the return of this blood internally,

the elimination of injurious waste matters through the skin, the

lowering of the febrile heat and tension, and a better functional

activity of all the organs of the body.

Similar good results are obtained from all remedies that induce surface

warmth and vascularity and a free secretion from the skin.

_Warm baths_, for animals to which they can be applied, abstract blood

temporarily from the inflamed internal organs, diminish the blood

pressure, and really cool the system, beside securing elimination from

the skin and other secreting surfaces. They may be commenced warm (80°

F.) and gradually cooled down to 65° F. after the skin has become freely

active. In the larger quadrupeds, in which the warm bath is too often

practically impossible, the same revulsion of blood and warmth to the

skin may be secured by _rags wrung out of hot_ (_almost scalding_)

_water_, wrapped tightly round the body, covered with two or more dry

blankets, and kept tightly applied against the surface by elastic

circingles. The legs may be rubbed with straw wisps till warm, and then

loosely bandaged, or applications of red pepper, ammonia, or mustard,

may be made prior to bandaging. In place of hot water rugs, bags loosely

filled with bran, chaff, or other light agent, heated to 110° F., may be

applied round the body, or, where it is available, a Turkish or steam

bath may be resorted to. These hot cutaneous applications, to produce

glow and perspiration, are especially valuable in the chill that heralds

a violent inflammation, and if that can be suddenly checked by this

means the inflammation will often be warded off, or at least rendered

slight and easily controllable. After perspiring for half an hour the

patient may be gradually uncovered, rubbed dry, and covered with a dry,

warm blanket. If the skin is still glowing, a slight sponging with cool

or cold water may beneficially precede the rubbing and drying.

_Cold Baths._ In cases of very high fever a full cold bath (68° F.) may

be employed for fifteen minutes, and repeated as often as the

temperature rises. In many cases of parturition fever in cows great

benefit accrues from sponging the body with cold water and allowing it

to evaporate from the burning skin. In the extreme fever of heat

apoplexy (sunstroke), with a temperature of 110° F. and upward, a strong

current of cold water from a hose directed on the head and body often

gives the best results. In ordinary fevers in large animals the _cold

pack_ will often serve a good purpose. Wring a blanket out of water

(cold or tepid, according to the height of the fever and the strength

and power of reaction of the patient), wrap it round the body, cover it

with several dry blankets so that no part is exposed, and keep the whole

in close contact with the skin by elastic circingles. In fifteen minutes

the skin should be glowing and perspiring, and in half an hour the

wrappings should be removed, a little at a time, the parts rubbed dry

and covered with a dry woolen blanket. It may be repeated as often as

the fever rises.

_Diaphoretics._ Besides these remedial methods of inducing a revulsion

and glow in the skin with perspiration, _medicinal diaphoretics_ may be

resorted to. Among these may be included _copious drinks and injections

of warm water_, _acetate of ammonia_, _antimony_, _ipecacuan_, or

_pilocarpin_, or one of the sedatives, _aconite_, _veratrum_, or

_opium_, etc. Many a threatened acute inflammation has been to a great

extent cut short and nipped in the bud—the stage of chill—by warm

clothing, active hand rubbing, and such an apparently unscientific

nauseant as tobacco.

When the preliminary stage has passed and the hot stage of the fever has

set in, cooling and eliminating agents are especially called for.

_Laxatives._ In many cases, and especially in those with marked

constipation or bowels loaded with indigestible materials, a laxative is

beneficial. For the horse, aloes, or, often better, sulphate of soda,

and for cattle or sheep, the latter, or Epsom salts, will at once remove

an irritant, cool the general system, draw off much blood and nervous

energy to the bowels, and secure a considerable depletion and

elimination from the intestines. For swine, dogs, and cats castor oil or

salts may be used, and for fowls castor oil. If the mucous membranes are

yellow, the tongue furred, and feces scanty, hard, and fœtid, a dose of

calomel (horse or ox, one drachm; sheep or pig, one scruple; dog, three

grains; chicken, one-half grain) with tartar emetic (horse or ox, two

drachms; sheep, twenty grains; swine, one-half grain; dog, one-fourth

grain; chicken, one-eighth grain) may be given and followed in ten hours

by one of the laxatives named above.

_Diuretics._ In the absence of any manifest disorder of the digestive

organs, the laxative may be omitted and refrigerant diuretics resorted

to. Acetate of ammonia or potassa, nitre, tartrate of potassa,

carbonates of potassa or soda, may be used along with sedatives.

In cases of infectious disease with poisoning by ptomaines and toxins

the elimination of these by the bowels and kidneys is of the greatest

importance.

_Sedatives._ Of the sedatives, aconite, bromide of potassium, veratrum,

hyoscyamus, or chloral hydrate may be used according to the special

indications.

_Alkalies._ _Resolvents._ When the organ inflamed is a serous membrane

in which dangerous adhesions or other functional disorders are likely to

occur from newly formed false membranes, their formation should be

counteracted as far as possible by the free use of alkalies (carbonates

of soda, potash, or ammonia, nitre, iodide of potassium, muriate of

ammonia, etc.), and in the same conditions excessive effusion should be

controlled by free action on the kidneys.

_Antipyretics._ To reduce the febrile temperature and especially, when

caused by the ptomaines and toxins of bacterial infection, agents like

acetanilid, antipyrin, exalgin, analgene, benzanilide, salicylate of

soda, and quinine have been largely employed and will usually lower the

temperature several degrees in a few hours. They nearly all depress the

vital forces, or hinder reparatory processes, so that their use is to be

carefully guarded. Quinine which is less depressing than the others

hinders migration of the leucocytes and thus stands in the way of

successful phagocytosis. With a dangerously high temperature they may be

temporarily admissible, but they should be suspended as soon as

possible. In all ordinary cases they are probably better avoided. A

judicious use of the cold or tepid bath, or of wet compresses is

incomparably safer and more generally applicable.

_Stimulants._ When the disease results in great prostration or when

symptoms of septic or ptomaine poisoning set in stimulants are often

required to sustain the flagging heart and circulation. These may be

alcoholic, ammoniacal, etherial, camphor, digitalis, etc.

_Tonic Refrigerants._ Later, when both inflammation and fever have been

somewhat reduced, temperature, breathing, and pulse rendered more

moderate, eye clearer, and even appetite perhaps slightly improved, the

sedatives may give place to refrigerating tonics, such as mineral acids

(nitric, muriatic, sulphuric, or phosphoric), in combination with

bitters (quassia, cascarilla, calumba, gentian, salicin), without as yet

the suspension of refrigerant diuretics. Thus for the horse the

following Recipe: Pharmaceutical nitric acid, two drams; infusion of

gentian, ten ounces; nitrate of potassa, two ounces. Dissolve. Give one

ounce every six hours.

_In Convalescence._ When convalescence has fairly set in, the fever has

subsided, and there remains merely some debility with a remnant of the

inflammatory exudation to be removed or organized into tissue, or when

an abscess has developed and burst, the tonics must be even more freely

given, the mineral acids may even give place to preparations of iron or

cod-liver oil, and the diet must be made increasingly liberal. But

throughout the whole progress of the disease the bowels should be

carefully watched. Costiveness may quickly undo all that has been

gained, hence any indication of this should be met by laxative food

(boiled flaxseed, etc.), or, this failing, by injections or laxatives.

Similarly, if a freer action of the kidneys seems to be necessary for

elimination of waste matters or to reduce fever, diuretics should be

continuously kept up.

TREATMENT OF ADYNAMIC INFLAMMATION AND FEVER. In treating _low asthenic_

or _adynamic inflammation_ all depression and depletion is to be

carefully avoided. Even _laxatives_ must be employed with extreme

caution. If absolutely necessary it is best to give them in small (half)

doses and supplement their action by liberal injections of hot water.

Elimination of waste matter from the blood and system is still to be

sought, but it must be by _stimulating diuretics_ (sweet spirits of

nitre, carbonate, acetate, or muriate of ammonia, digitalis), and direct

_stimulants_ and _tonics_ must be given from the first (ammonia, wine,

strong ale, whisky, brandy, ether, gentian, calumba, nux vomica). For

the horse the following may serve as an example: Recipe: Sweet spirits

of nitre, four ounces; sulphuric ether, two ounces; tincture of gentian,

ten ounces; digitalis, one dram. Mix. Dose, two ounces in a pint of cool

water four times a day. When there is great debility and prostration

ammoniacal and alcoholic stimulants must be given freely, while if the

fever heat rises very unduly the cooling diuretics (citrate, tartrate,

or acetate of potassa, or nitre, etc.), and even sedatives (bromide of

potassium, hydrobromic acid, chloral hydrate, salicin, salicylate of

soda), must be resorted to. If there is any indication of a special

depressing poison in the system, or of the absorption of septic or other

noxious matter from a wound, antiseptics (hydrochloric acid, or

salicylic acid, sulphite of soda, quinia, or chlorate of potassa) may be

advantageously added to the prescription.

In these cases of asthenic inflammation, as in the advanced and

debilitated stages of sthenic inflammation, the diet should be as good

as the patient can digest. Boiled oats, barley, or flaxseed, rich,

well-boiled gruels, and beef-tea (even for herbivora,) may frequently be

resorted to with advantage.

_Local Treatment of Inflammation._ In all forms of superficial

inflammation the local treatment occupies an important place. The

persistent application of _cold_ (cold water in a stream, icebags,

freezing mixtures) will sometimes overcome the tendency to inflammation

or arrest it. This is especially sought when a violent inflammation (as

in a wounded joint) threatens to destroy an important organ. If adopted,

it must be persisted in, as if it is suspended too soon the reaction is

likely to make matters worse than ever. _Cold astringent applications_

have a similar tendency. Sugar-of-lead, one-half ounce; laudanum, one

ounce; water, one quart, may be kept applied by means of a linen

bandage. The water may often be advantageously replaced by extract of

witch-hazel. If the inflamed part is superficial the lotion may be made

_antiseptic_ (carbolic acid, one dram; or sulphurous acid solution, five

ounces; water, one quart). _Hot applications_, _fomentations_,

_poultices_ are nearly always appropriate but they should be made

antiseptic to prevent bacterial development. When adopted they should

like _cold_ ones be kept up as continuously as possible. These soothe

alike the superficial and deeper parts, the latter through sympathy,

producing first a relaxation of vessels and tissues, and later a

contraction of the former attended by pallor of the surface. They

greatly favor suppuration when that is already inevitable, though in

other cases they may obviate it by checking at an early stage the acute

inflammatory process on which it depends. Any bland agent that will

retain heat and moisture will make an excellent poultice, though

flaxseed-meal is the type of a soothing demulcent application. Very

slight inflammation may be successfully treated at the outset with a

_stimulating embrocation_ (alcohol or camphorated spirit), yet in the

more violent type of acute inflammation all local excitants tend to

aggravate the disease. In these violent forms the activity of the

disease should be first abated by local soothing and general sedative

measures, and then the part over the inflamed organ may be safely

treated with a stimulating liniment or even a blister. In such cases the

liniment first acts as a derivative of blood and nervous energy from the

inflamed part, and later and still more beneficially by securing in it a

sympathetic healing process, like that set up in the skin. It is further

probable that the absorbed albuminoids, which have been modified in the

congested part often exercise a decided effect on the inflamed tissue.

In raw sores where inflammation has been set up the granulations may

become dropsical or excessive, bulging beyond the adjacent skin as

_proud flesh_. This should be repressed by touching it gently with some

mild caustic (lunar caustic), so as to produce a thin, white film, and

the remote cause of the inflammation (often a local irritant) should be

sought and removed. In some unhealthy sores tending to excessive

granulation, the compound tincture of myrrh and aloes may be applied

daily with great benefit. When the granulations become excessive they

may be scraped down to the level of the skin and then treated with an

antiseptic (iodoform, boric acid, acetanilid, aristol).

_Blistering._ In subacute and chronic inflammations and in those acute

forms in which the violence of the inflammatory action has been already

subdued by soothing measures, blisters and other counterirritants may be

employed to counteract the remaining inflammatory action. These act

primarily by drawing off blood and nervous energy from the inflamed

organ to the skin, and secondarily, by establishing a sympathetic

healing process in the diseased part, simultaneously with the work of

recovery in the skin, when the blister has spent its action. But if

applied above a part which is still violently inflamed, there is apt to

be serious aggravation, through this same sympathy with the part

suffering under the rising of the blister. In this way great and

irreparable injury is often done through the laudations of particular

blisters for the cure of given diseases, without any reference to the

stage or grade of such disease. The value of a blister depends far more

on the time of its application than on the ingredients of which it may

be composed.

_Firing._ This acts in nearly the same manner as a blister, and demands

similar caution in its application. It is especially available in

subacute and chronic diseases of the joints, bones, and tendons, and may

be made more or less severe according to the nature and obstinacy of the

disease. It is applied in points or in lines at intervals of one-half to

one inch, and penetrating one-third, one-half, or entirely through the

skin. The hotter the iron the less the pain, but the greater the danger

of destruction of the intervening skin by the excess of radiating heat.

Hence the contact of the heated iron with any one part must be

judiciously graduated to the heat of the iron and the delicacy of the

skin, and should not exceed the fraction of a second.

_Massage, Rubbing._ In chronic inflammation and even in some acute

forms, with considerable exudation, rubbing or massage is of great

value. It hastens the progress of the blood through the veins, tends to

restore the normal circulation in the stagnant or partially obstructed

capillaries, moves on the exuded liquids in the lymphatic plexus,

rendering the absorption more active, and at once prevents the process

of disintegration of the tissues and obviates, the necessity for their

solution and removal. This may be largely accomplished by the use of the

brush or rubber, or by careful manipulation especially in the direction

of the veins. If the inflammation is near the surface the use of

antiseptic and deobstruent agents will heighten the good effect.

Iodoform, iodide of potassium, boric acid may serve as examples.

_Suppuration._ _Abscess._ The great variety of the causes and forms of

suppuration would forbid any extended notice of its treatment in this

place. It seems preferable to refer the reader to the subject of pyæmid

and the various surgical and medical diseases in which suppuration takes

place.
