Part 6

[51] Indolence of the action does not imply that the quantity of a discharge should be lessened, but only that its nature should be changed. In this species, the discharge is much the same in quantity as in a healthy ulcer of the same size, but its perfection is greatly less.

[52] Sometimes the granulating action and the cicatrizing one seems to be confounded, the surface exhibiting a fibrous fleshy appearance. This I have seen most frequently in the calf of the leg; but it may occur in other parts.

These appearances vary in degree from the soft pale surface, and thin whitish purulent discharge, with slightly thickened edges, to the state now described. The pain, when compared to the size of the ulcer, is not considerable.

This genus may occur, in a slight degree, in recent sores, from neglect, &c.; but it is chiefly after ulcers have been of long standing, that they assume these appearances in the greatest degree. They may then be said to have become chronic, or habitual; and, in many instances, it is absolutely impossible to restore the action to its natural state, and produce recovery[53].

[53] These ulcers, after long continuance, frequently induce a disease in the bones or muscles seated below them, as will afterwards be mentioned.

The second species is distinguished by the paleness and imperfection of the granulations, whilst the discharge is tolerably good; but it never can be equal to that of the healthy ulcer; because, when one part of the action is affected, the other is also more or less affected. This species does not require any more particular observation or remark, because it is to be treated exactly as the first, of which it is often just a slighter degree, or a forerunner; for it is frequently the first change which takes place in a healthy ulcer. When it becomes diseased, it does not continue long; for both parts soon come to suffer in the same proportion; in which case, the ulcer belongs to the first species. For this reason, we never find old ulcers belonging to this species.

Chronic ulcers sometimes induce a disease of the bones, &c. below; but, in this case, they generally are converted into a different genus. They also come naturally, in consequence of the great imperfection of their action, and the consequent want of power, to act beyond the due proportion betwixt action and power; and, therefore, most ulcers of this genus come at last, if neglected, to belong to the next.

The most effectual remedy for these ulcers is pressure. This has been long employed, by means of tight rollers wound round the limb, or by the laced stocking. But, of late, a more effectual method has been proposed, namely, a bandage of adhesive plaster, which applies itself closely to the surface, and produces a state of artificial contact and covering. This has been recommended by Dr. Darwin in the form of a many-tailed bandage, and by Mr. Baynton in the form of strips, wrapped round the limb. The following is the method of applying them: A strip of adhesive plaster, about an inch broad, and so long as to encircle the limb and cross at each end, is to be warmed, and the middle of it applied to that part of the limb which is exactly opposite to the sore; both ends are now to be brought forward, and one of them laid tightly over the under part of the sore (if it be so large as not to be covered with one strip), whilst the other is brought firmly over this from the opposite side, and doubled down upon it. The ends of the strip thus fold over each other at the ulcer. Another strip is then to be applied to the part of the sore contiguous to this which is not yet covered, and so on in succession, until the whole be covered. This is the best way of applying the strips, if the integuments be firm; but, if they be loose and yielding, it will be useful to push forward the loose skin from behind, with the strips, as we bring them forward; and, instead of laying down first one end, and then the other over it, make the two ends cross each other at the same time, and lay them down upon the skin, and not on each other, the under end covering the lower part of the sore, and the upper the part next it. The same strip, therefore, covers two portions of the surface, whereas, in the first way, it covered only one; but, in this case, the strip must be longer, as it must fairly cross the ulcer on each side, and be retained by sticking to the adjacent skin. When the ulcer is deep, the strip will press only on the margins; and, therefore, it will be useful to fill up the surface with a fold of soft lint. A thin cotton roller is now to be wound firmly round the limb, beginning at the extremity, and continuing the bandage to the next joint above the sore.

By this contrivance, we obtain a firm covering to the granulations, and bring a substance in contact with each individual. We then restore, as it were, the natural state of the parts, each granulation having a substance in contact with it; and a slight interstice is left between each, owing to their pointed structure. They become, therefore, similar, in this respect, to the organic particles of internal parts; on which account, healing goes on more quickly, and the organic particles, or granulations, are deposited in greater perfection, and with greater powers of action; for the unusual and morbid condition of exposure and want of contact is now removed. The same circumstances promote cicatrization, when the granulations have risen to a proper height. This is more evidently seen in the cure which is effected of the smaller ulcers, by dusting them with chalk, &c. or dressing them with an ointment made thick with some mild powder, by which a scab, or covering, is formed, which operates clearly independently of pressure. Pressure, applied with this view, ought to be moderate and permanent, and may be used with utility in almost every case of solution of continuity, however healthy the action may be. But, besides being of use in this way, pressure also produces a second set of effects, by mechanically exciting action in the part to which it is applied. Applied to the skin, it increases the cuticular action, and the skin is formed thicker. Applied to a weakened part, it increases the natural action of that part, and strengthens it: This is seen in the instance of debilitated muscles, &c. But, if the pressure be too great, then a morbid increase of action takes place, which even goes the length of inflammation, if the pressure be considerable; and this inflammation is either strong or weak, according as the pressure has operated; for, if many vessels be obstructed, as is commonly the case, then the power of the part is injured, and the action is weak; or, the same happens if pressure be applied in any manner to a weak part, or if the constitution be weak; as, for instance, from previous disease.

Pressure, applied to a part, increases in particular the functions of absorption and deposition. If moderate, these functions are moderately increased, and the structure of the part continues either the same, or it augments in size, as we observe, in the effects of walking, on the skin of the feet; but, if the pressure be greater, then these functions are morbidly increased, the particles are deposited imperfectly formed, and are as quickly taken up. The structure is therefore destroyed, and a vacuity formed. These effects are produced more easily upon diseased than healthy structures; because their powers of acting, and sustaining action, are less. Friction is in this respect similar to pressure.

From these remarks, we may understand the mechanical utility of pressure in the cure of ulcers; for, when in a proper degree, it causes the absorption and destruction of the callous edges, or diseased substance, and likewise makes, if moderate, the diseased granulations be taken up, and more healthy ones be formed. We may likewise perceive, that, if the degree be too great, the action will become of an inflammatory nature, and injury will be done. We are therefore frequently under the necessity of counteracting this hurtful effect; for, the degree of pressure which is requisite for answering the first intention in old sores, or inducing action, in consequence of bringing the granulations or particles into the natural state of being in contact with some body, or covered by it[54], is often attended with such mechanical irritation, that the one effect would destroy the other, unless we kept the action within due bounds, by applying cold to the part. In healthy ulcers, the pressure necessary to produce its first set of effects, or to accelerate healing, by producing contact, is so trifling, that no counteracting effect takes place by the production of the second set of effects; and, therefore, no cold requires to be applied: But, in old ulcers, the pressure must be greater; and, therefore, cold water must be constantly applied to the bandage over the sore, by means of a sponge. We thus indeed lessen the effects of pressure on the absorbing system, and, therefore, the callus will be longer of being destroyed; but we, on the other hand, prevent the action of the granulations from being rendered morbid.

[54] The degree of pressure necessary for producing this effect is proportioned to the susceptibility of the granulations, or organic particles, for receiving the impression of being in contact. When a part is healthy, the mere circumstance of juxtaposition is sufficient for this purpose; and, in a healthy ulcer, the weight of the body applied, such as powdered chalk, or plaster of Paris, or at least the gentle pressure of a stocking, or easy bandage, is all that is necessary. But, when the action is too low, and the granulations are consequently imperfect, both in their structure, power of acting, and capability of receiving impressions, the contact, in order to operate, must be nearer, and more complete; or, in other words, the pressure must be greater. In these cases, bandages not only act on the surface, but also on the parts below, and, therefore, increase the degree of contact of the newly-formed organic particles, and thus strengthen the part.

The good effects of pressure, applied in a degree proportioned to the effect which we wish to produce, and to the state of the sore, are so universal, that it is unnecessary to give any examples of its success and utility. But, at the same time, it must be observed, that in old ulcers, and even in many of a more recent date, which have been much neglected, no application whatever will produce an uninterrupted cure; for, after some time, it ceases to produce the same effect upon the action. The part seems, by continuance, to be less acted on by the agent; the action is less affected, and slowly returns to its former state of imperfection. It is therefore necessary, either that we from time to time increase the power of our application, or vary our remedies, whenever the process becomes stationary. The latter is generally the most effectual way; and the remedies which we alternate with the effects of pressure, are those of what have been called the stimulating kind; but which of the individuals of this division ought to be employed, cannot always be determined, because one succeeds better in a particular instance than in another. It would, however, be of much importance, to ascertain which in general operated most effectually; because, if we employ one which does no positive good, we sustain positive harm; for the action is allowed to persevere in a retrograde process. I, therefore, paid particular attention to the operation of these applications, in the patients who were under my care in the Glasgow Infirmary.

Heat is found to increase almost every action; and, therefore, in indolent ulcers, it is sometimes of use, especially for a few days after we begin the management of the sore, as it paves the way for the action of other agents, by beginning a change of the action. Poultices are the vehicle by which it is most frequently applied, and answers, in general, better than other forms. Fomentations are much used by many practitioners, who employ decoctions of different kinds of vegetables; but they have no superiority over poultices. Dry heat was used by M. Hevin, who held ignited charcoal near the sore; and it is sometimes of use to repeat this practice betwixt each dressing.

Electricity is of little service; because it cannot be constantly employed; and, therefore, its operation is only temporary.

It is worthy of observation, that although this kind of ulcer may be sometimes completely cured by the use of heat, that yet the action is not so perfect, and consequently the structure and power of the part is weaker, than when stimulating dressings are employed. Exercise, or any other cause, is therefore more apt to injure the part afterwards, and make it again break out into an ulcer.

The red precipitate, mixed with resinous ointment, in the proportion of a drachm of the former to an ounce of the latter, is a very useful dressing; but the ung. hyd. nit. mixed with four times its weight of hog’s lard, forms an ointment which is still more generally useful.

Ten grains of the cuprum ammoniatum, rubbed up with an ounce of basilicon, or simple ointment, is sometimes useful, but cannot be depended on. The same may be said of an ointment composed of an ounce of ung. simplex, and ten drops of the oil of cloves, or of savin.

Cloths dipped in the aqua zinci vitriolati, or the solution of cuprum vitriolatum, diluted with water, so as only to smart moderately, are likewise of service, but not so frequently as weak solutions of the nitrates of silver, zinc, copper, bismuth, and many other metallic salts, such as muriate of mercury, &c.

Solution of common salt, or of nitre, of such a strength as to produce a moderate smarting, are of temporary advantage, but will not continue their effect long. Indeed all solutions of saline substances, whether alkaline or metallic, are most useful when applied only for half an hour at a time, when the sore is dressing.

Mixtures of Thus, elemi, turpentine, canadine balsam, &c. with wax, or oil, have no advantage over the common ung. resinosum[55].

[55] An ointment composed of these resinous substances is much recommended in the Acta Med. Berolin. Tom. VII. p. 58.

The bile, either by itself, or diluted, or mixed with yolk of eggs, does not seem to be of much service.

Lemon juice, or the mineral acids, particularly the nitrous, diluted so as to be of equal strength with the juice, are frequently of service[56]. Port wine is also an useful lotion.

[56] These acids coagulate the pus, and thus afford an artificial covering, or film, which remains in close contact with the granulations, and thus, by producing the natural circumstance of contact and covering, the effects of which have been already mentioned, as well as by creating a more vigorous action by their specific action, they frequently bring those sores into a healthy state.

Infusion of Cayenne pepper, in vinegar, added to water, in such a quantity as to smart, forms also a very useful application.

Of all these remedies, the ointments composed of the nitro-metallic salts, particularly the mercurial, are most generally useful: And the cure seems to be accelerated, by applying cloths dipped in weak solution of metallic salts, or weak acids, during the intervals of dressing. Whenever these applications fail, they must be dropped: And those which fail first, and soonest, seem to be the watery, or fluid applications; and, next to these, the simple resinous ointments.

These remedies generally produce their effect first at the margins. When this takes place, we must diminish the strength of the application at that part, in proportion to the activity of the action, which is marked by the redness and pointedness of the granulation, and the cicatrizing state. The circumference, and the rest of the surface, must, in this case, be dressed with different strips of linen, spread with different ointments. Soft linen, spread with simple cerate, or dry lint, which is preferable, should be applied to the cicatrix, and cicatrizing granulations, whilst a stimulating substance is applying to the rest of the surface.

When the surface is obstinately diseased, or the action very torpid and imperfect, caustic has been applied; but, although I have often used it, and even applied cloths dipped in solutions of metallic salts, so strong as to form an universal eschar, or slough, yet no benefit whatever was derived; for we do not thus change the nature of the action, but only remove a layer of the surface, and leave that below in possession of the same mode of action with the former. Caustic is more useful, when applied to callus edges; but even these are more effectually removed, by remedies which act more permanently, and gradually, particularly by pressure. The ancients used to extirpate these with the knife, but few will consent to its use. It is indeed more speedy and effectual than the caustic; but, unless the action be afterwards properly supported, it will be of no permanent service.

The hard and thickened state of the surrounding integuments, in old ulcers, is best moderated by pressure; but this must be long continued.

Varicose veins, were, by the ancients, considered as canals running into the sore, and furnishing the discharge; but, when we consider that these varices frequently occur without any ulceration, or discharge, the opinion must be abandoned. In such cases as occur alongst with ulceration, it will be more natural to consider the affection of the vein as a disease dependent originally on the ulcer, and induced by it, in the same way as the structure and functions of other neighbouring parts are changed and impaired by the continuance of a tedious and diseased ulcerative action. This state of the vein being once induced in any part of it, and even in a slight degree, two consequences follow: First, from the power or property of the vein being impaired, the blood is not duly propelled, but circulates slowly, and cannot overcome readily the weight of the blood above, which presses more powerfully, in consequence of the valves being rendered imperfect by the distension of the vessel. The disease, therefore, gradually increases; for, every day, the power of acting properly diminishes, at the same time that the mechanical necessity for acting, or the resistance of the column of blood increases. On account of the dilatation of the vessels, and the morbid or abortive effect to propel what they are unable to do, pain is produced, in the course of the varix, whenever the legs are kept in a dependent posture, or exercise is used. This pain is confounded with the uneasiness arising from the ulcer; and, therefore, these ulcers are said to be painful, and to be attended with pain in the course of the veins.

The second consequence is, that, as the veins which are more immediately connected with the ulcerated part, are diseased, and do not perform their part in the circulation properly, the functions of the part must be still more injured, and the varix, which originally perhaps was produced by the ulcer, comes in its turn to act on the sore, and prevent its healing; for the vein not acting properly, and conveying the blood fully, the action at the capillaries must be injured, and the artery and vein cannot act healthily. If this be the case, the power of forming granulations must be impeded, and these never can be deposited in the necessary degree of perfection.

Two modes of cure have been proposed, the one palliative, and the other radical. The first is effected by means of rollers, or bandages, which prevent the vein from being distended, and, therefore, enable it the better to carry on its circulatory function. In this way, we prevent, to a certain degree, the hurtful operation of the vein upon the ulcer, and are often enabled to heal it up. But, as we do not thus restore the vein to its natural powers, unless in young people, who continue the support or pressure for years, we can obtain no permanent cure of the varix; and very frequently the parts again ulcerate; because, whenever the pressure or support is withdrawn, and the patient walks about, then the function of the part becomes affected, the organic particles are not deposited in the same state of perfection, and the action which is induced by exercise causes the destruction of these granulations; or even the very circumstance of their being formed imperfectly is sufficient to produce their destruction, and the opening of the part; for all parts which have been formerly ulcerated are most ready to assume this action again, and the organic particles of that part are less perfect, and less able to bear action.

The second is obtained, by obliterating the diseased vein, or interrupting its communication with the trunk above, by which we make the blood take a different course, and be transmitted by healthy veins. If we now cure the sore, we find, that the same effects are produced as if we used permanent pressure; and, therefore, the functions of the part are more properly performed, and the organic particles possess greater power of acting, and sustaining action. The older surgeons proposed to effect the radical cure, by tying the vein at the two extremities of the diseased part, and cutting out the intercepted portion, or by laying it open, and digesting it, as they said. This, however, was, as they confess themselves, very seldom submitted to in ulcers of the legs; and was rather inserted to complete their treatises, than from a belief that the operation ought to be insisted on. Of late, it has been proposed by Mr. Home, to tie only the upper extremity of the diseased portion[57], by which adhesion takes place at that spot, and the circulation is there stopped. The pressure of the blood above is thus taken off, and the blood from below must circulate, in a greater degree, through vessels which are better able to perform their functions; and, therefore, the actions of the capillary vessels, whether nutrition, absorption, or conversion of the blood from arterial into veinous, must be more naturally performed. After the veins are tied, they gradually become smaller; for the pressure being permanently removed, the diseased veins can more fully propel their blood by lateral branches, at the same time that they receive less blood, more going by other vessels.

[57] This operation is performed by making an incision through the skin which covers the vena saphena below the knee; a ligature is then passed under the vessel, by means of a blunt needle, and the vessel is tied. In two or three days the ligature may be removed, its circle being previously divided with a pair of scissars.
