292. The wind of a cannon-ball has been supposed to exert some influence on the brain when passing close to the head; there is, however, no valid foundation for the opinion. An officer of the fifth division was struck by a cannon-shot, during the assault of Badajos, on the right side of the head and face. It carried away the right eye and the whole face, the left eye hanging in the orbit, the floor of which was destroyed. A part of the lower jaw remained on the left side, but a great part of the tongue was gone. He had lost a large quantity of blood, but was quite sensible. In the middle of the next day he suffered much from the want of water to moisten his throat, which could not be procured. After a distressing delay of three or four hours under a hot sun, a small quantity was obtained, the arrival of which he observed; and while I was giving directions relative to its distribution, I felt a gentle tap on my shoulder, and on turning round saw this unfortunate man standing behind me, a terrific object, holding out a small cup for water, not one drop of which he could swallow. Alone among strangers, he felt that every kindness in our power to offer was bestowed upon him, and he contrived to write his thanks with a pencil, which he gave me when he pressed my hand at parting at eleven at night. I was glad at sunrise to find he had just expired.
293. When a portion of bone is as it were sliced off with the scalp and adheres to it firmly, the scalp and bone should be reapplied; and the cure will often be effected without difficulty. When the portion of bone cut off and hanging to the scalp, which is turned down, has but little adherence, it should be removed.
A German dragoon was brought to me in front of Madrid, who had received a slicing cut of this kind on the top and side of the head, which caused a portion of the scalp and parietal bone to be turned down over the ear, uncovering the dura mater. Replaced and retained in its situation, the flap and bone appeared to adhere, and the man recovered. In the case of a Portuguese soldier cut down by the French cavalry in a sortie during the second investment of Badajos, a portion of bone cut off with a flap was quite loose, and was removed. The patient did equally well.
In the museum of the Royal College of Surgeons there are ten skulls which have suffered from very severe slicing cuts. They appear to have been collected from the burial-place of some establishment for invalid soldiers in Germany. The portions of bone thus sliced, and they are large pieces, were once detached, and afterward reunited a little out of their proper places, so that the points of separation and of union can be distinctly seen. These fissures are all in a certain state of progress toward being filled up by bone, and the patients must have lived some months, if not years, after the receipt of their respective injuries; for bone is deposited apparently with difficulty and most carefully in all such cases, so as not to irritate the membranes of the brain. The opening in the first instance is filled up by granulations, over which a thin skin is formed; this afterward becomes firmer and harder, being in some cases, where the trephine had been used, a thin but strong membranous expansion extending from one edge of bone to the other. In others it is thicker and more solid, and in a few instances osseous matter is deposited in its circumference, so as in part to fill up the opening, the edges of the bony circle made by the trephine becoming gradually thinner as they appear to grow inward. It is common for an exfoliation to take place in such cases from the edges of the cut bone, and from the circle made by the trephine. It has been occasionally observed, after death, that the circular cut edge of the bone does not become thin in the manner described, but that a sort of ridge forms around and within it.
When the scalp is torn down without being much bruised, and a large flap extending from the occiput to the forehead falls down on the shoulder, covered with blood or dirt, the flap should be cleansed and restored to its place. When it is large, two or three sutures may be necessary to keep it in its proper situation. The flap may not entirely adhere under any management, but it will do so in parts; and care should be taken to evacuate at an early period any matter which may form by small but sufficient incisions made where required; this will in general be above and about the ear. When the flap is much bruised, the attempt at adhesion by close apposition will be useless until after suppuration has taken place, when a well-regulated pressure will do much toward expediting the cure.
294. Erysipelas occurs in two forms: when the skin has the ordinary redness characteristic of the complaint, and when the color of the skin is not altered or is whiter than natural, but puffed, tense, and shining, the inflammation being seated beneath the tendinous expansion of the occipito-frontalis muscle.
The general treatment should be regulated by the powers of the patient and the state of the constitution, (Aph. 24, page 39.) The local treatment of the first form essentially depends on puncturing the red and inflamed skin all over with the point of a lancet, assisting the flow of blood by warm fomentations. The punctures should be repeated, if necessary. The second form is to be treated by incisions, perhaps the greatest improvement of the surgery of the Peninsular war.
The scalp in such cases is in a state of general puffiness, causing the head to look considerably larger than usual, but without redness; it retains the impression of the finger. Incisions are to be made in the scalp from two to four or six inches in length, united by others, if necessary. The scalp will often be upward of an inch in thickness, and filled with a fluid partly serous, partly purulent. The small arteries bleed freely, and should be allowed to do so as long as may be desirable, when the hemorrhage should be arrested by pressure. The head should be fomented. The essential points are, to take off tension, and to allow the free discharge of any fluid which may be secreted. The moment the parts around a wound have become puffy, the surface of the wound changing from a red to a yellowish color, with a thin discharge instead of good pus, an incision should be made through them, and repeated, if necessary. It relieves the tension and the irritative fever, and prevents the delirium which would follow; which neither bleeding, purging, nor the other constitutional remedies which the state of fever may indicate will remove. If it should be neglected, suppuration and sloughing will extend under the tendon of the occipito-frontalis, or the fascia of the temporal muscle, and the greatest danger will be incurred from this additional cause.
