CHAPTER V

+WOUNDS AND CONTUSIONS+

A wound is a solution of continuity or division of the soft tissues

produced by cutting, tearing, or compressing force. The classification

of wounds according to their causation or nature is as follows:

_Incised_—when resulting from a sharped-edged instrument.

_Lacerated_—when tissues are extensively torn or separated.

_Contused_—when resulting from a more diffused force, tearing

and bruising the tissues.

_Punctured_—when produced by a narrow instrument that causes a

wound deeper than its external surface is broad.

_Poisoned_—when some poisonous substance enters the wound and

causes local infection or constitutional disturbance.

_Gunshot_—when the injury results from firearms or powder

explosion.

+An Incised Wound+ is an injury which is produced by some sharp

instrument such as a knife, pieces of glass or metal, which divides

the tissues cleanly, producing no bruising or tearing. The pain is

usually sharp and burning, varying with the nature of the instrument

with which the injury has been inflicted. Hemorrhage is usually free.

+Lacerated Wounds.+ These usually result from machinery accidents or

from heavy bodies passing over the parts and are apt to contain a

considerable quantity of foreign matter ground into the tissues.

+Contused Wounds.+ A contused wound is one in which the edges and

surrounding tissues are bruised or crushed. External bleeding as a

rule is not excessive, although there is a great likelihood of

extensive subcutaneous hemorrhage. Sloughing and gangrene may occur.

+Punctured Wounds.+ The character of a punctured wound depends upon the

object producing it. If made by sharp instruments, such as knives,

swords, daggers, bayonets, or needles, their nature is similar to

incised wounds.

Unless organs of importance have been wounded, or unless active septic

material has been carried into the wound, healing promptly follows

after the withdrawal of the instrument which has caused the wound.

These wounds are usually deep when affecting the dorsal aspect of the

foot, being commonly caused by a falling instrument or tool. In the

plantar region they are of every degree of severity, from the most

minute puncture to perforation running between interosseus spaces and

passing through the dorsal skin. The most frequent punctures are those

caused by stepping upon needles, pins and tacks. These wounds are,

commonly, of no importance unless the foreign body is broken off or

entirely penetrates the foot.

If the patient is seen a very short time after this has occurred, the

surgeon may operate with some confidence of finding the offending

substance, but even here, if possible, it is an advantage to obtain an

X-ray picture, while in those cases in which a needle has long been

buried in the tissues, this is quite indispensable. It is well to

remember that in these cases the patients’ impressions us to the

location of the needles are most unreliable.

After a radiograph has been obtained, it is most important, if

anatomically possible, to make the incision at right angles to the

shaft of the needle. At least two pictures should be taken in order,

if possible, to obtain some idea of the depth at which the needle

lies. Even with all these helps, the procedure, simple though it may

at first appear, oftens turns out to be one of great difficulty,

necessitating a very extensive operation.

+Incised Wounds of the Foot.+ Incised wounds of the dorsal surface are

very frequently quite deep and often implicate the tendons, bones and

articulations, as they are most frequently inflicted by the fall of

some heavy tool upon the part, or by the inaccurate blow of an axe.

Wounds of slight importance need but the usual thorough cleansing out,

with or without suturing of the skin, according to the extent of the

incision.

If one or more of the tendons have been severed, the ends should be

approximated by catgut sutures. If extensor tendons are cut in the

neighborhood of the metatarsophalangeal joints, it is often necessary,

owing to considerable retraction of the distal end, to incise the skin

down as far as is needed, in order to secure the retracted end and

suture it. Failure to adopt this procedure permits a dropping of the

toe, converting it often into a regular hammertoe. When the tendon is

properly sutured, the toe must be placed for some days in a condition

of over extension, most easily secured by a bandage passed under it,

acting like a stirrup, the ends being fastened by several turns above

the ankle.

Incisions, implicating joints, are carefully cleansed by flushing the

joint with copious quantities of saline solution, and closing the

wound with very few stitches. Such injuries should be examined daily

and any sign of sepsis must be considered as an indication for

immediate removal of the stitches, followed by active antiseptic wet

dressings.

Cuts of the plantar surface are not often very extensive. They are

most frequently incurred in stepping upon some sharp instrument or

walking upon glass, especially while bathing.

+Contusions.+ A contusion or bruise is a subcutaneous laceration, the

skin above it being uninjured, as in the abdomen; or being damaged

without a surface breach, as in a part overlying bone, and blood

being effused. If a large vessel is damaged, hemorrhage is extensive.

An _ecchymosis_ (black and blue area) is diffuse subcutaneous

hemorrhage.

A _hematoma_ is a blood tumor or a circumscribed hemorrhage in the

tissues.

In a diffuse hemorrhage the coagulation of fibrin induces induration,

the serum and leukocytes are absorbed, the red blood cells

disintegrate, and the coloring matter is widely diffused by the tissue

fluids, and hemoglobin is changed into hematoidin which crystallizes.

In union with these chemical changes, color changes ensue, the part

being at first red and then becoming purple, black, green, lemon and

citron. The stain following a contusion is most marked in the most

dependent area.

A hematoma acts as an irritant, inflammation ensues around it and it

is encapsuled by embryonic tissue, which, by organizing into fibrous

tissue, forms a blood cyst and gradually absorbs the fluid blood, the

cysts contents becoming thicker and thicker. A fibrous scar may

remain, and a blood clot, with very much indurated surrounding tissue,

giving a hard edge, is noticed after bruises of the periosteum. If

serum is not absorbed, hematoidin forms and the fluid becomes clear. A

hematoma may suppurate, an abscess forming, but this rarely happens

except in drunkards, although it occasionally occurs in persons who do

not use alcohol.

+Symptoms.+ The symptoms are tenderness, swelling, pain, and numbness.

The pain may be severe, but rarely persists beyond the first

twenty-four hours. Discoloration appears quickly in superficial

contusions, but only after days, in deeper ones. Shock and loss of

function are present only after severe contusions. The swelling is

first due to blood and is soon added to by inflammatory exudation.

+Terminations of Contusions.+ Slight contusions terminate promptly by

resolution; the more severe may terminate in gangrene, inflammation,

abscess, fibroid thickening, hypertrophy of the tissues involved, (as

in the case of bone), chronic inflammations, and even malignant

growths, particularly sarcomata.

+Prognosis.+ The prognosis of contusions is a matter of every day

importance, and it is sometimes extremely difficult to prognosticate

accurately. The determining forces are principally the nature and

violence of the contusing force, the tissues and organs involved, and

the general condition of the patient. Even the injury of the tissues

that may be easily inspected, such as the skin, may be much more

severe than is apparent. In tissues of low vitality, such as synovial

membrane, cartilage and ligaments of a joint, repair is

proportionately delayed, whereas in highly vascular tissue it is more

rapid. Contusions of tissues that cannot be given physiologic rest,

such as the thoracic wall, and the respiratory muscles, respond less

promptly to treatment.

The general condition of the patient is an important factor in the

prognosis, the most favorable being vigorous adult life without

organic disease. Among the unfavorable general states are, the

extremities of life, the very anemic and the plethoric, the

tuberculous, the syphilitic, the diabetic, and like diatheses, while

in the rheumatic and the gouty, the slightest injury may be most

persistent. The starved, the overfed, the over-worked, the fatigued,

the alcoholic, and those exposed to extremes of heat and cold, are

unfavorably affected.

+Treatment.+ Slight bruises, favorably located, require no treatment.

The arrest of hemorrhage, thereby diminishing the swelling, pain, and

discoloration, is important. If the hemorrhage be from small vessels,

elevation, rest, and the application of ice are sufficient. Frequently

the application of pressure is indicated. Hemorrhage in deeper parts,

such as that occurring under the fascia of the thigh, is sometimes

best controlled by adhesive strapping. If the vessels are large and

the hemorrhage is rapid, it is sometimes necessary to make a free

incision and apply a ligature. Evaporating lotions or elastic pressure

by bandaging over absorbent cotton, may assist. If the hemorrhage be

in a joint causing immediate swelling, painful from distension,

prompt aspiration will give relief. This should only be resorted to

under the strictest aseptic precautions, as the conditions are

favorable for microbic growth. If the soft parts are so severely

contused as to jeopardize the nutrition, both bandaging and ice should

be withheld, and in some instances even warm applications are advised.

After the acute symptoms have passed, judicious massage may be most

helpful in securing early resolution. Restoration of the vasomotor

tone when impaired or lost may be greatly facilitated by douching with

cold and hot water alternately followed by massage. During the acute

stages, physiologic rest is important; the restoration of functional

use in severe cases must be tentative, guided by the response of the

tissue in the form of increased pain or swelling. These phenomena

should be avoided if possible. If hematomata be not absorbed they

should be aspirated and pressure applied before structural changes

take place, such as the formation of a membrane. If the latter occurs

and sufficient time has elapsed for the formation of definite new

tissue, aspiration may be followed by the obliteration of the sac.

Sometimes hematomata become so thoroughly and firmly organized and

gradually increase in size, that it is extremely difficult to

differentiate them from new growths. If pain and tenderness persist

for a long time, particularly, if there be a predisposition to

tuberculosis, especial care is necessary.

+Treatment of Wounds in General.+ Arrest hemorrhage, bring about

reaction, remove foreign bodies, asepticize, drain, coaptate the edges

and dress, secure rest to the part and combat inflammation.

Constitutionally, allay pain, secure sleep, keep up the nutrition and

treat inflammatory conditions.

+Arrest of Hemorrhage.+ To arrest hemorrhage the bleeding point must be

controlled by digital pressure until ready to be grasped with forceps;

it is then caught up and tied with catgut or aseptic silk. Slight

hemorrhage stops spontaneously on exposure to air, and moderate

hemorrhage ceases after the vessels are clamped for a time; an

injured vessel of some size must be ligated, even if it has ceased to

bleed.

Capillary bleeding is checked by hot water compresses. In bringing

about reaction from shock, raise the feet and lower the head, unless

this position causes cyanosis. At least place the head flat and the

body recumbent. Apply hot water bottles and hot blankets and give

hypodermic injections of ether, brandy, strychnine, digitalis or

atropin, or inhalations of amyl nitrate. Strychnine can be used in

large doses, one-thirtieth of a grain may be given every ten or

fifteen minutes, until three doses have been taken. If the skin is

very moist, atropin is indicated, alone or combined with strychnine.

Hot coffee, or other hot fluids, should be given by the mouth and

rectum, and mustard should be placed over the heart, spine and shins.

The use of hot and stimulating rectal enemata is very important. The

rectum may absorb when the stomach refuses to do so. Enemata of hot

normal saline solution are very beneficial.

+Enteroclysis.+ The tube is carried into the sigmoid flexure and the

injection is introduced so as to distend the colon. At times it may be

necessary to give an intravenous injection of saline solution in order

to overcome the shock. In order to prevent the suppression of urine,

it may be necessary to administer diuretics.

+Removal of Foreign Bodies.+ Remove with forceps, all foreign bodies

visible to the eye: splinters, bits of glass, portions of clothing,

dirt, etc.

In a lacerated or contused wound, portions of tissue injured beyond

repair should be regarded as foreign bodies and should be removed with

scissors.

+Cleaning the Wound.+ If the surface is hairy it must be shaved before

the scrubbing. An accidental wound is infected and must be well washed

out with an antiseptic solution. A clean wound, made by the surgeon,

need not be irrigated, in fact, irrigation with an antiseptic fluid

leads to necrosis of tissues, causes a profuse flow of serum and

necessitates drainage. If clots have gathered in a wound, they must be

removed, as their presence will prevent accurate coaptation of the

edges. In an infected wound, they are washed out with a stream of

corrosive sublimate solution. In a clean wound, they are washed out

with hot salt solution. If dirt is ground into a wound, as is often

seen in crushes, pour sweet oil into the wound, rub it into the

tissues, and scrub the wound with ethereal soap. The oil entangles the

dirt and the soap and water remove both dirt and oil. After the rough

cleansing, irrigate with corrosive sublimate solution. In some cases,

especially in bone injuries, it is necessary to scrape the wound with

a curet.

A granulating wound is treated the same as an ulcer and the treatment

is discussed under that chapter.

+Drainage, Closure and Dressing.+ Superficial wounds require no special

drain, as some exudate will find exit between the stitches and the

rest will be absorbed. A large or deep wound requires free drainage

for at least twenty-four hours by means of a tube, strands of horse

hair, silk, catgut or gauze. An infected wound must invariably be

drained. Good drainage largely compensates for imperfect antisepsis.

If capillary drains be employed, apply a moist dressing. Divided

nerves and tendons must be sutured. Close the edges with silk sutures

or silkworm gut if the wound is deep and tension inevitable. Catgut is

used for superficial wounds and for those where tension is slight. The

interrupted suture is, as a rule, the best. If the wound is infected,

dress with antiseptic gauze; with aseptic or antiseptic gauze if it is

not infected. A dry dressing absorbs wound fluids quickly and is less

likely to become infected. Change the dressings in twenty-four hours

or sooner if they become soaked with the discharge. After this, in an

aseptic wound the dressing need not be changed for days. If pus forms,

open the wound at once.

+Rest and Constitutional Treatment.+ In planning the treatment of wounds

the most careful consideration for securing physiologic rest should be

had. If at or near a joint, the parts both above and below should be

immobilized. In whatever part of the body, physiologic rest should be

secured as nearly as possible. If the wound be of the leg or foot, the

patient should be in the recumbent position, with the part elevated

and a splint applied. The factor of rest, next to that of cleansing

and dressing, is most important. Physiologic rest means not only less

pain, less reaction, but a more rapid and certain repair.

Under ordinary circumstances no special constitutional treatment is

necessary beyond that of securing good hygienic surroundings, easily

digested food, restricted at first, and free action of the bowels. If

there is great pain, opiates may be necessary, but here, as in other

surgical indications for anodynes, a minimum amount should only be

given. Usually rest, elevation, and relief of tension will be of

greater benefit than opiates. If there is great restlessness, a

bromide may suffice; if marked insomnia, one of the ordinary

hypnotics. Great restlessness, with excitement and occasional

delirium, without special evidence of pain or infective process, must

call attention to the possible development of delirium tremens from a

relatively slight injury (such as a crushed toe or a simple fracture),

as it may precipitate an attack in one who has been a steady drinker,

though perhaps not an excessive one. In such cases, in addition to the

ordinary therapeutic remedies, the regular administration of whiskey

should be advised.

+TOXEMIA, SEPTICEMIA, SAPREMIA, PYEMIA+

+Toxemia+ applies to the diseases in which one or more poisons are

present in the blood which are not necessarily of parasitic origin and

production.

The word poisons is here used in a broad sense to cover any substance

applied to the body, ingested, or developed within the body which

causes disease. It of course includes ptomains, leukomains, toxins and

sepsins.

Toxemia, according to this definition, would include the diseases due

to poisons not arising from parasitic invasion of the tissues and

fluids of the body, at times of vegetable and alkaloidal nature, such

as strychnine or morphine; of animal origin, such as the toxin of

snake venom, the ptomains of milk or shell fish; then again a mineral

such as arsenic or lead; and lastly the leukomains arising from

disturbed excretion and perverted metabolism and grouped under such

terms as intestinal or uremic poisoning.

+Septicemia+ may be defined as an acute febrile affection, characterized

by marked nervous, cutaneous and visceral manifestations, and due to

the introduction into the system of bacteria and their toxins from an

infected wound. It applies to diseases which present poisons in the

blood that are of parasitic origin, the parasite itself being either

present or absent in the blood. Septicemia, in strong contrast to the

definition of toxemia, would include diseases arising from the

invasion of the tissues and fluids of the body by animal or vegetable

parasites or their poisonous products.

+Symptoms.+ The onset, as a rule, is slow, beginning from 4 to 7 days

after an injury, with a chill, which is followed by fever, at first

moderate, but soon becoming high. The fever presents morning

remissions and evening exacerbations and may occasionally show an

intermission. When the remission begins, there is a copious sweat. The

pulse is small, weak, very frequent, and compressible; the tongue is

dry and brown with a red tip; the vomiting is frequent, and diarrhea

is the rule; delirium alternates with stupor, and coma is usual before

death; prostration is very great, and visceral congestion occurs; the

spleen is enlarged, ecchymoses and petechiae are noted, secretions dry

up, urinary secretion is scanty or is suppressed, and the wound

becomes dry and brown.

Blood examination detects disintegration of red globules and marked

leukocytosis. When a wound becomes septic, red lines of lymphangitis

are seen about it and there is enlargement of the related lymphatic

glands. No thrombi or emboli exist in septicemia. The prognosis is

bad, and in some malignant cases death occurs within 24 hours.

+Treatment+ is the same as for septic intoxication (see “_sapremia_”).

Antistreptococci serum can be used, but the value of this method is

doubtful.

+Sapremia+ may be defined as an intoxication due to the absorption of

dead saprophytes and their products (ptomains and toxalbumins).

+Symptoms.+ The disease sometimes begins with a chill, followed by a

marked rise in the temperature, but in most cases the latter is the

first evidence of the disease. The skin becomes cold and clammy, there

is marked prostration and sometimes diarrhea. When these

manifestations occur while a wound is present, they are ominous, and

the dangerous complications can be avoided if the dressing of the

wound is renewed and perfect antiseptic precautions are taken to

thoroughly remove all septic matter from its surface. The

constitutional symptoms often disappear of their own accord, when the

above has been done, unless the systemic intoxication has not already

advanced to thwart all endeavors. There is also a diminution or

suppression of the urine, and a blood examination shows leukocytosis.

+Treatment.+ The treatment is at once to drain and asepticize the putrid

area and to give large amounts of alcohol. Strychnine and digitalis

are useful. Purge the patient, and favor diaphoresis, using in some

cases the hot bath. Establish the action of the kidneys; allay

vomiting by champagne, cracked ice, calomel, cocain or bismuth. Give

liquid food every three hours. Feed on milk, milk and lime water,

liquid beef, peptonoids, and other concentrated foods. Use quinine in

stimulant doses. Antipyretics are useless. Watch for visceral

congestion and treat it at once.

The use of saline fluid by hypodermoclysis or by venous infusion

dilutes the poison and stimulates the heart, skin, and kidneys to

activity.

In sapremia the blood contains the toxins and dead saprophytic

organisms. In septicemia the blood contains both pyogenic toxins and

multiplying pyogenic organisms. In sapremia the causative condition is

putrid material lodged like a foreign body in the tissues. In septic

infection the tissues themselves are suppurating, and both bacteria

and toxins are absorbed by the lymphatics. Of course, septic infection

may be associated with septic intoxication or may follow it. The

symptoms of sapremia depend upon the amount of intoxication.

In septic infection, or septicemia, only a small number of organisms

may get into the blood, but they multiply rapidly. A drop of blood

from a man with septic infection will reproduce the disease when

injected into the blood of an animal; hence it is a true infective

disease. The wound in such a case is often small, and is commonly

punctured or lacerated.

+Pyemia+ may be defined as a condition in which metastatic abscesses

arise as a result of the existence of pyogenic bacteria in the

circulating blood, either free or contained in pus cells or thrombi.

+Symptoms.+ The symptoms of pyemia are a febrile movement with a severe

chill and a sudden marked rise in the temperature which lasts for a

few hours and passes off with profuse sweating. The chills recur every

other day, every day, or oftener. The general symptoms of vomiting,

wasting, etc., resemble those of septicemia.

The lodgment of emboli produces symptoms whose nature depends upon the

organ involved. If in the lungs, there is shortness of breath and

cough, with slight physical signs.

In a suspected case of pyemia, always look for a wound, and if this

does not exist, remember that the infection may arise from an

osteomyelitis.

Chronic pyemia may last for months; acute pyemia may prove fatal in a

few days.

+Treatment.+ The treatment is the usual supporting one that should be

employed in septic affections, and all suppurating focci must be

opened and drained as soon as detected. Every branch of the irregular

cavities must be opened and drained at the most dependent part, and

the sinuses must be treated to prevent pocketing. Serum therapy is

also indicated.
