The simplest and readiest way to apply pressure is by the fingers. But first of all some knowledge of anatomy and physiology is necessary to guide the operator where to press. Bleeding from the head and upper neck requires pressure to be exerted on the large artery which passes up beside the windpipe and just above the collar-bone, as in Fig. 110. The artery supplying the arm and hand runs down the inside of the upper arm almost in line with the coat seam, and should be pressed, as shown in Fig. 111. The artery feeding the leg and foot can be felt in the crease of the groin, just where the flesh of the thigh seems to meet the flesh of the abdomen, and this is the best spot to select in the case of a male patient; but in the case of a female, unless the injury were very high up the thigh, it would be more judicious perhaps to apply increased pressure around the leg about half-way between the hip and the knee. Pressure with the hands will not suffice to restrain severe bleeding for any length of time, and recourse must be had to a ligature.
The simplest and most available form of ligature is a pocket-handkerchief or neck-wrap, or any other article of attire long and strong enough to bind the limb. Fold the article necktie fashion, then place a smooth stone or anything serving as a firm pad on the artery, tie the handkerchief loosely, insert any available stick in the loop, and proceed to twist it as if wringing a towel until tight enough to stop the flow of blood, as in Fig. 111.
In the case of bleeding from an external wound or sore on the body, employ direct pressure over the bleeding point. If the bleeding is from the interior of the nose or other cavity, apply cold water or ice over the bleeding part or near it, and keep the patient perfectly quiet on the back, or let the patient stand erect with head well thrown back. Injection of hot water into the nostrils is very effective. When the bleeding is from a diseased surface or ulcer, and direct pressure does not stay it, a compress should be soaked in a strong solution of alum, or in steel-drops, and again applied over the point which is bleeding. Should the wound from which the blood is coming be large and gaping, you may stuff firmly into it a compress of some soft material large enough to fill the cavity; but this should always be avoided if possible, as it prevents the natural junction of the sides of the wound, and is very likely to introduce the germs of poison. In any case of bleeding the patient may become weak or may faint, but unless the blood is flowing actively, this is not necessarily a serious sign, and the quiet condition of the circulation during the faint often assists nature in staying the bleeding, by allowing the blood to clot, and so block up any wound in a blood-vessel. Unless the faint is prolonged, or the patient is losing much blood, it is better not to hasten to relieve the faint condition.
When blood is being coughed or vomited up in considerable quantities, ice or iced water or milk should be given, and the patient be allowed to breathe cool fresh air freely. If the blood is coming from the lungs, inhaling steam of turpentine and hot water mixed (2 tablespoonfuls turpentine to 1 qt. hot water) will often reduce the evil; apply cold wet cloths to the chest.
Broken bones.—Never move a patient with a broken bone till it has been suitably bandaged. Broken bones (fractured) are of three kinds—(a) simple fracture, when the bone is simply broken in one place; (b) compound fracture, when there is a wound in the flesh communicating with the broken ends of the bone; (c) comminuted fracture, when the bone is broken into pieces. The occurrence of a fracture may almost always be learned from the history of the accident, the patient having generally felt or heard the bone snap; other indications are deformity of the limb, such as shortening or bending, and on taking hold of the limb, you will find there is increased movability, and will hear and feel a peculiar grating caused by the broken ends of the bone rubbing against each other, called “crepitus”; also pain and loss of power in the limbs.
It is not imperatively necessary to do anything to a broken limb before the arrival of a doctor, except to keep it perfectly at rest, unless the patient must be moved; then, to prevent further mischief, the broken ends of the bone must be put in position and kept there. The first step is to pull the limb till the sinews and muscles stretch sufficiently to let the two ends of the bone meet each other. When this has been done, splints and bandages must be applied to keep the ends from shifting again.
The treatment of a broken bone then consists of (1) carefully removing or cutting away, if more convenient, any of the clothes which are compressing or hurting the injured parts; (2) very gently replacing the bones in their natural position and shape, as nearly as possible, and putting the part in a position which gives most ease to the patient; (3) applying some temporary splint or appliance, which will keep the broken bones from moving about and tearing the flesh, for which purpose you may use pieces of wood, stick, tin, pasteboard, wire, straw, or firmly folded cloth, taking care to pad the splints with some soft material, and not to apply them too tightly, while the splints may be tied by loops of rope, string, pockethandkerchiefs, pieces of cloth, or any kind of cord; (4) conveying the patient home or to a hospital, meanwhile examining the loops to see that they do not become too tight by rapid swelling of the part.
To get at a broken limb or rib, the clothing must be removed, and it is essential that this be done without injury to the patient. The simplest plan is to rip up the seams of such garments as are in the way. Boots must be cut off.
In a fracture of a leg bone, after setting the broken limb and putting it in splints, it should be bound to the sound leg at the knee and ankle, with rolled up coat for the sides and a piece of thin board or other substance for the front of the thigh. A broken arm, when in splints, requires the support of a sling, which may be made of a handkerchief fastened round the neck.
Bandaging can hardly be learned from a book—some practice is essential. Bandages are made of unbleached calico, flannel, linen, &c., and are used as supports to the different parts of the body, as means of applying pressure, for fixing splints, dressing, &c., and for allaying muscular action. The chief kinds are the roller and the triangular bandages.
