Puncture wound

“ Definitions.—Surgically a wound means a solution of continuity and refers to every such lesion produced by external violence or developing spontaneously. The medico-legal acceptation of the term is much broader and includes any injury or lesion caused by mechanical or chemical means. Vibert [601] quotes Foderé as defining a wound medico-legally as, “Every lesion of the human body by a violent cause of which the results are, singly or combined, concussion, contusion, puncture, incision, tear, burn, twist, fracture, luxation, etc. ”

“ The place selected should be carefully cleansed with water, soap and 1/1000 mercuric chloride solution, and finally with alcohol and ether. A puncture is made with a sterilized triangular needle or knife, or a stub-pen with one point broken off. The last-named makes a most useful and inexpensive instrument for this purpose. The puncture should be made by a quick and deep stab, so that sufficient blood can be obtained from one stab-wound. Pressure should not be employed to force blood from the wound. ”

“ Wounds and other injuries of the organ are generally followed by inflammation. But a simple clean wound or puncture made with a fine instrument, as in many operations, and in a favourable constitution, frequently produces little or no excitement of the part. The degree of excitement must of course depend upon the nature of the wound, the structure of the parts involved, the lodgement or not of the body by which the wound is inflicted, and many accidental circumstances. The eye may be injured by acids or by lime, and the textures acted upon chemically ”

“ Puncture wounds wherein the vulnerant body is of small diameter, are observed, and they occasion deep seated infectious inflammation of the parts affected, with surface wounds that are often unnoticeable. Such injuries—puncture wounds—are always serious, and because of the fact that, there exists little evidence of injury at the time of their infliction, treatment is usually deferred several days and often infection has become quite extensive when the practitioner is consulted. ”

“ In most cases the wound is painful, sometimes exaggerated by the mental condition, which is wrought up to a pitch rarely seen in other equally fatal injuries. It is often difficult to discern the exact point of puncture, so minute is it. There is swelling due to effusion of blood, active inflammation, and increasing pain. If the poison has gained full entrance into the system, in a short time the swelling extends, vesicles soon form, and the disorganization of the tissues is so rapid that gangrene is liable to intervene before the fatal issue. ”

“ WOUNDS AND CONTUSED INJURIES OF THE ABDOMINAL WALL AND VISCERA.
Such wounds and injuries of the abdominal wall may be incised, punctured, or due to blunt instruments, etc. They are usually homicidal or accidental, seldom suicidal except in delirious patients or lunatics. The cause of death in such cases may be due to hemorrhage, shock, etc., or to secondary inflammation, which is especially likely to occur in penetrating wounds. The kind of weapon used may often be judged from the nature of the wound. ”

“ A gangrene and mortification is only to be dreaded, when a whole limb is inflamed, such as an arm, a leg, &c. When the inflammation is dreadful, that the blood can find no passage at all, but is obstructed on all sides, then the part must naturally die, and become cadaverous. The cause of this misfortune may be either a heavy contusion, a compound fracture, a gun-shot wound, or an internal malignity of the bone itself; and as a caution, I must also add, that pricking a tendon in bleeding may occasion this dreadful malady. ”

“ Punctured wounds are always more dangerous than incised. They cause little, if any, hæmorrhage externally, unless a large vessel, such as the femoral artery, be injured, but they may cause internal hæmorrhage or penetrate a viscus, e.g. the lung or heart. These wounds generally heal by suppuration, and not infrequently an abscess is formed in and around the track of the wound. Perforating wounds generally have a large entrance wound with inverted edges, and a small exit with everted edges; if the weapon be rough, the reverse may be the case. ”

“ If, on the contrary, the hemorrhage is slight in amount or almost fails altogether; if it is venous in character; if the edges of the wound are only stained by imbibition of the blood, which is not infiltrated between the tissues, and the stain may be washed off; if the blood is not at all or only slightly clotted and the clots are soft; if the skin is not everted and the sides of the wound are smooth and lie nearly in contact ”

“ Punctured wounds of the third class made by instruments with ridges or edges, like foils, files, etc., present more or less the shape of the weapon if the edges are cutting, but not always so if the direction of the wound be oblique or the parts unevenly stretched. If the edges are not cutting they cause wounds more or less like the first class of punctured wounds, but we can often distinguish them from the latter by little tears in the edges. ”

“ Incised or punctured non-penetrating wounds of the thoracic wall are rarely grave. Bleeding, as a rule, is not serious, though it may be quite free. Such wounds may be accompanied by emphysema, though not penetrating, owing to the movements of the chest and a valve-like action of the edges of the wound. Contused wounds of the thorax are more dangerous, especially if the violence was great, owing to the complicating fracture of the ribs, rupture of the thoracic viscera, etc. ”

“ Let patient lie flat and swallow small pieces of ice, and also take one-quarter teaspoonful of table salt in half a glass of cold water.
BRUISE.
First Aid Rule 1.—Bandage from tips of fingers, or from toes, making same pressure with bandage all the way up as you do over the injury.
Rule 2.—Apply heat through the bandage, over the injury, with hot-water bottles.
Cause, Etc.—A bruise is a hidden wound; the skin is not broken. It is an injury caused by a blunt body so that, while the tougher skin remains intact, the parts beneath are torn and crushed to a greater or lesser extent. ”

“ The more violent symptoms arise from examining bodies which are rather recent, and in which putrefaction is just commencing, and very frequently from inspecting the bodies of females who have died of puerperal diseases. The absorption may take place from punctures made by scissors, the point of a knife, or spiculæ of bone, or from old scratches, or chops by the side of the nail or on the hand. There is little or no danger from an open and bleeding wound, as by the flow of blood the part is completely cleaned; it is generally from slight punctures that untoward symptoms need be apprehended. ”

“ But sometimes the discharge of blood is so great, that if it be not stopt, the patient may die even before a surgeon, though at no great distance, can arrive. In this case, something must be done by those who are present. If the wound be in any of the limbs, the bleeding may generally be stopt by applying a tight ligature or bandage round the member a little above the wound. ”

“ When loss of blood occurs without the lung being wounded, the hemorrhage is probably proceeding from a wound of one of the intercostal arteries, which has been torn by the sharp ends of fractured bone. ”

“ If blood is dark, and comes in slow flow (venous) —
Tie a cloth around between end of limb and wound. Or use a tourniquet, loosening it in one hour.
Using a Tourniquet
In either case, bandage a clean gauze compress against wound. If unable to use these methods because of too rapid bleeding, press fingers into wound, but have another person tie as described. Do not use finger pressure if possible to avoid, for the wound should be kept clean.
Any of the following tend to stop bleeding:
Ice or ice water. Very hot water. Vinegar, 1 tbsp. to 4 tbsp. water. Salt, 1 tsp. to 4 tbsp. water. ”

“ What nerves or blood-vessels, particularly arteries, have been injured, should be ascertained. It is often important to determine whether a wound was made before or after death. The following may serve as a differential point: In all wounds made after death there is slight bleeding, non-contraction of the edges, and absence of blood in the tissues. This is the opposite of ante-mortem wounds. ”

“ Frequently in open fractures large quantities of pus constantly remain in contact with the surface of the wound, while detached fragments of bone, which become speedily necrosed, move about with every motion of the injured limb, lacerating more or less the surrounding tissues, and thus exciting inflammation and suppuration. ”

“ It should be added that for 'explosive' features to reach their strongest development, it is necessary that the bone affected should lie near the surface of the body; hence the most characteristic explosive wounds were met with in the forearm or leg, over the metacarpus or metatarsus, or in the arm. In the thigh, on the other hand, where the femur in a great part of its course not only lies deeply, but is also protected by particularly strong and resistent skin and fascia, another type of wound was met with. ”

“ In incised wounds the bleeding is usually free at first, but unless one of the larger arteries, such as the external maxillary (facial) or temporal, is injured, it soon ceases. Paralysis of the muscles of expression may follow if the facial nerve is injured; and loss of sensation may result from injury to the supra-orbital or infra-orbital nerves. If the parotid gland is implicated, saliva may escape from the wound, but it usually ceases in a few days; if the duct is involved, a persistent salivary fistula may form. ”

“ 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. ”

“ A Simple Wound is that which only opens the Flesh, and hath no other concomitant Circumstances; but a Complicated Wound, on the contrary, is that which is attended with grievous Symptoms, as Hæmorrhages, Fractures of Bones, Dislocation, Lameness, and others of the like Nature.
What is a dangerous and mortal Wound?
A dangerous Wound is that which is complicated the Accidents whereof are dreadful: As when an Artery is open'd or prick'd, when a Nerve or Tendon is cut, or when the Wound is near a Joynt and accompanied with a Dislocation or Fracture. ”

“ Pain.—As an initial symptom the occurrence of pain varied greatly with the idiosyncrasy of the patient, and according to the circumstances under which the wound was received. Some individuals are remarkably insensitive, and in these the fact of a wound being a gunshot injury in no way altered their habitual insensibility, but in persons of what may be termed the normal type in this particular great differences were observed. ”

“ Contusions and Contused Wounds.—A contusion is a wound of living tissues by a blow of a hard body, not sharp-edged or pointed, or by a fall, crushing, or compression, and without solution of continuity of the skin. A contusion usually involves a moderately large surface in comparison to the two other classes of wounds. Contusions are of all degrees of severity. If the blow or injury is slight, there is only slight redness and swelling of the skin with pain, disappearing in a few hours, and leaving no traces. ”

“ If the wound is small, the old-fashioned clean white rag that has been boiled and washed is as good as anything that can be used for a dressing. Tear off a narrow strip from one to two inches wide and as many feet long, according to the position of the wound, roll it round the finger or limb three or four times, and then take a turn round the wrist or nearest joint, to keep the bandage from slipping off. If the wound be likely to keep on oozing blood, put on first a thickness of surgeon's cotton, or prepared cotton-batting, an ounce of which can be purchased for ten cents at any drugstore. ”

“ Further, a hemorrhage during life is an active and not a [484] passive one; the blood is forced into the interspaces of the tissues in the vicinity of the wound, and is found infiltrated in the cellular tissue, the muscles, the sheaths of the vessels, etc. It is here incorporated, as it were, with the tissues so that it cannot be washed away. In an ante-mortem wound the arterial nature of the hemorrhage may show by the marks of the jets of blood about the wound or on the clothes or surrounding objects. ”

“ Penetrating wounds may exist without wound, or with wounds of one or more of the viscera of this cavity. Among the more serious complications with which the latter may be accompanied is the lodgment of the projectile or other foreign bodies, as of fragments of bone, within the chest. As wounds of the heart and great vessels are almost invariably at once fatal, and as the organs of respiration occupy the greater part of the cavity of this region, it is in reference to the latter that the treatment of chest wounds is chiefly concerned. ”

The aperture of exit in simple wounds of the soft parts sometimes heals even more rapidly than that of entry, and [Pg 75] if of the slit form may be almost invisible at the end of ten days or a fortnight, actual primary union having taken place as after a simple small incision. ”

“ But I am persuaded from repeated observations, that the disease is no ways influenced by this circumstance. I am satisfied likewise that there is no difference between the effects of the matter, whether it be taken in its watery and purulent [317] state. The puncture should not be larger than is sufficient to draw one drop of blood, but it should always be made by a sharp lancet, for the sudden inflammation and suppuration, excited by a dull lancet, sometimes throw off the matter, so as to prevent its infecting the body [59] . No plaster or bandage should be applied over the puncture. ”
