OF SCALDS AND BURNS.
Different degrees of injury are inflicted on the surface from the application of heated solids or fluids. The term scald is generally confined to the effects of heated fluids, whilst burn denotes the consequences of the application of a heated solid, or of ignited combustible matter; the latter class of accidents is, in general, the more serious, yet the former, though not injuring the skin deeply, gives rise to the most alarming symptoms when a large extent of surface is affected. A slight degree of heat is productive only of redness of the surface, with a sharp hot pain, and these symptoms may subside with or without vesication. However, effusion of serum under the cuticle often takes place almost immediately after the contact of the heated body—the cuticle may be destroyed by the intensity of the injury—or the true skin may die, either partially or throughout its whole thickness, and the subjacent parts be at the same time injured to a greater or less depth. But parts, not severely injured at first, may afterwards perish, violent inflammatory action being excited, which terminates in sloughing. The neighbouring parts have their vitality much diminished, by the direct influence of the injury; and hence, when these parts come to be the seat of increased action, sloughing almost inevitably ensues, from the want of corresponding power. From the same cause, subsequent sores are tedious in healing, being so far debilitated as to be unable to assume full vigour; even slight ulcerations following vesication contract very slowly; the granulations are flabby, and the discharge profuse and thin. The inflammation is often at first very violent, and kept within bounds with difficulty. Burns of the trunk, particularly of the genital organs, are to be considered as attended with much danger. And extensive burns and scalds, wherever situated, are always to be dreaded. Violent constitutional irritation takes place, dyspnœa is apt to occur, with effusion into the chest of serum, or a sero-purulent fluid; and the nervous system ultimately becomes oppressed. Great sinking of the vital powers is generally the immediate consequence of extensive and severe burns; there is shivering, weakness of the pulse, cold extremities, anxiety, and vomiting, requiring the exhibition of warm drinks, and even sometimes of cordials, opium, or strong stimulants. These must, however, be given with a sparing hand, or the depression following the excitement is with difficulty got over. Nor can it be matter of surprise that such serious effects occur, when we reflect on the extreme sensibility, and highly organised state of the affected part, and the important functions which it is intended to perform, as well as those sympathies which it holds with internal parts, on which life principally depends.
In trifling burns cold applications are generally used—as immersing the part in cold or iced water. A great variety of remedies are employed, spiritous, watery, acid, alkaline, cold or hot; some apply a coat of cotton or flour, some of tar or pitch, and they state that when these artificial crusts separate, the skin is found healed beneath; in fact, every practitioner, and almost every individual, possesses a favourite application for this very common accident. Some have recommended holding the part to the fire, or plunging it into hot liquid; but this practice, and all similar, are too severe ever to become general, when milder means prove equally effectual. Perhaps the most common applications are, a mixture of lime-water and olive oil, or the ceratum acetatis plumbi. The vesicles, when left to themselves, burst, expose an irritable surface, and the acrid discharge from them excoriates the surrounding skin. Their contents ought to be evacuated by a small puncture, and the cuticle being left carefully undisturbed, a scab soon forms, by which the part is protected while healing. In extensive injuries of the skin, where the cuticle has been altogether destroyed, finely carded cotton is sometimes applied; it is of use in somewhat the same way as the cuticle in the former instance, and being a sort of cushion over the part, prevents it from being irritated by bed or body clothes, or by the patient’s resting on it. It soon becomes soaked with the discharge, and must either be frequently changed, or become a receptacle for pus to putrefy in, and maggots to breed; on account of these circumstances it is objectionable. Dusting the part with common flour, starch, or hair powder, is equally advantageous, and much more convenient; relief is afforded by its immediate application; the parts are cooled; the flour, absorbing the discharge, is soon formed into crusts, which effectually protect the surface; and the after-secretion readily escapes from beneath this, no more moisture being imbibed than is merely sufficient for the encrustation. The artificial covering ought not to be removed until completely detached, by purulent matter accumulating beneath it; then its presence can be of no service, and its removal is accomplished by fomentation or poultice, and without pain to the patient; whereas, by pulling off the crusts shortly after their formation, as some do, whilst they are adherent to the surface, and protecting it from injury, much pain is given to the patient, the raw surface is irritated, and made liable to over-action; a useful application is taken away to make room for another, and, perhaps, not so congenial. After the spontaneous separation, fresh flour may be again sprinkled over the suppurating surface, and, if the affected part is small, it may heal under this application. But when, in burns of considerable extent, suppuration is fully established, and granulations have begun to arise, tepid-water dressing, and lotions, are to be applied as to any other granulating sore; for the reasons already assigned, the applications require to be of a gently stimulating nature.
In severe cases, there is first extreme depression of the powers of life, under which patients sometimes sink; but most frequently this state is obviated by the employment of cordials or stimulants. But these ought to be administered with caution, for reaction soon commences, and often increases to well-marked inflammation, requiring for counteraction low diet, and even bleeding. In such cases gentle laxatives are preferable to purgatives, as by the latter the patient is obliged to make frequent movements, and those are always painful. Stimulants have been strongly recommended, at first powerful, and afterwards gradually weaker, so as, it was said, to restore the balance between the affected parts and the system; and the latter is again to be excited, in order to meet the increased action which the parts assume. The practice is founded on fancy, and cannot become general, being in its first part cruel, and in its second absurd. Whilst debility exists, stimulate cautiously; when over-action ensues, adopt those measures which are best calculated to subdue excitement; this is common sense, and the common practice.
During the process of healing, position of the parts ought to be carefully attended to; contraction of the cicatrices, and cohesion of opposed surfaces often causing unseemly deformities. Surfaces opposed to each other, and naturally separate, may be prevented from uniting by dressing interposed; and contraction of joints is to be guarded against by keeping the limb extended by splints and bandages. Where deformity has occurred, the hardened cicatrix which is in fault may be either divided or excised, and by paying attention to position in the after-treatment, the evil may be greatly lessened. In the case of contracted joints, it is not necessary to excise the whole or greater part of the callous web; simple division is sufficient, if carried deep enough, through the altered and condensed cutaneous tissue. A horrid case of deformity is sketched on the next page, and from a very horrid and atrocious scoundrel, the companion and assistant of Messrs. Burke, Hare, and Co., the Thugs of the Modern Athens. In such a deformity the art of surgery could not avail. In others, however, the cicatrix is not so extensive; it is separated into bands, by the division of which the position of the head and lip is improved, and the comfort of the patient much enhanced. In one case, in which I operated with success very lately, the scar, though extensive, was remarkably soft and pliable, as much so as the finest kid leather.
