PREFACE.

The following pages are presented to the medical public with very

humble pretensions. It is chiefly with the minor accidents or diseases

that they have to do; but I shall not consider that I have laboured in

vain, if I am enabled to mitigate even these little evils of human

life.

In these prefatory observations, however, I would suggest the question

whether the caustic may not be employed with benefit even in some of

the severer diseases to which the human frame is liable. Indeed I

consider the investigation as only just begun, and many other uses of

the lunar caustic, besides those detailed in the following pages, have

suggested themselves to me.

May not the caustic, for instance, be of greater efficacy, because of

greater power and of quicker operation, than ordinary blisters, in

some internal diseases?

It is repeatedly stated hereafter, that the application of the lunar

caustic is a means, in certain circumstances, of subduing external

inflammation. Might it not, on this principle, be of service in the

treatment of some of the internal phlegmasiae?

It may be observed, that the lunar caustic may be regarded, almost

without further trial, as an effectual preventive of those cases of

irritative fever which arise from local injuries, and probably of the

effects of poisoned wounds in general. I would not, however, in the

latter cases, fail to render "sure doubly sure" by free excision.

Might not an adherent eschar be easily formed in those cases of

compound fracture in which the external wound is of moderate size, so

as effectually to exclude the external air and prevent cutaneous

inflammation, and in more respects than one, to reduce the case to the

state of a simple fracture? This object, if attained, would be

important indeed, and I hope the suggestion will be submitted to the

most assiduous and cautious trial.

I can have no doubt that the use of the lunar caustic admits of being

still further extended; and, as I intend to pursue the inquiry, I hope

at some future period to publish something more worthy of the

attention of the medical public. In the mean time, the plans hereafter

suggested must not be adopted without that degree of care, attention,

and perseverance, which are obviously necessary to render them

successful.

CHAPTER I.

ON HEALING BY ESCHAR.

Having been led, by several circumstances, to try the effects of the

Lunar Caustic in the treatment of Wounds and Ulcers, and having great

reason, from these trials, to think that this remedy may be used with

much advantage far more extensively than has hitherto been done, I lay

the results of my experience before my medical brethren.

A very natural mode of healing certain wounds and ulcers, is by

scabbing; but this mode of treatment is attended by many

disadvantages, as will be pointed out shortly; yet it may be supposed

to have suggested to me some of those trials of the treatment by

eschar, which I am about to detail.

I. ON THE ADHERENT ESCHAR.

It appears scarcely necessary to describe the immediate and well known

effects of the application of the lunar caustic to the surface of a

wound or ulcer. It may, however, be shortly observed that the contact

of the caustic induces, at first, a white film or eschar which, when

exposed to the air, assumes in a few hours a darker colour, and at a

later period, becomes black; as the eschar undergoes these changes of

colour it gradually becomes harder and resembles a bit of sticking

plaster; in the course of a few days, according to the size and state

of the wound, the eschar becomes corrugated and begins to separate at

its edges, and at length peels off altogether, leaving the surface of

the sore underneath, in a healed state.

In the formation of this eschar several things require particular

attention. The application of the caustic should be made over the

whole surface of the sore; and indeed no part requires so much

attention as the edges; to make a firmer eschar the caustic should

even be applied beyond the edge of the wound, upon the surrounding

skin, for the eschar in drying is apt to contract a little, and in

this manner may leave a space between its edges and that of the

adjacent healthy skin.

At the same time, much attention must be paid to the degree in which

the caustic is applied. In cases of recent wounds unattended by

inflammation, it may be applied freely; but when inflammation has come

on, too severe an application of the caustic induces vesication of the

surrounding skin, and the edges of the eschar may in this manner also

be loosened and removed. If every part is touched, a slight

application of the caustic is generally sufficient.

The importance of avoiding all causes which might detach the edges of

the eschar will be apprehended by the following interesting

observation, which I have been enabled to deduce from very extensive

trials of the caustic; it is, that, in every instance in which the

eschar remains adherent from the first application, the wound or ulcer

over which it is formed, invariably heals.

Not only the cause just mentioned, but every other by which the eschar

might be disturbed, must, therefore, be carefully avoided; and

especially, as the eschar begins to separate from the healed edges of

the sore, it should be carefully removed by a pair of scissors.

To the surface of the wound the eschar supplies a complete protection

and defence, and allows the healing process to go on underneath

uninterruptedly and undisturbed. It renders all applications, such as

plasters, totally unnecessary, as well as the repeated dressings to

which recourse is usually had in such cases; and it at once removes

the soreness necessarily attendant on an ulcerated surface being

exposed to the open air. In many cases too, in which the patients are

usually rendered incapable of following their wonted avocations, this

mode of treatment saves them from an inconvenience, which is, to some,

of no trifling nature.

It has already been stated how important it is that the eschar should

be preserved adherent. To secure this still more effectually, I have

found it of great utility to protect it by a portion of gold-beater's

skin. The skin surrounding the wound is simply moistened with a drop

of water, and the gold-beater's skin is then to be applied over it and

over the eschar, to which it soon adheres firmly, but from which it

may be removed at any time, by again moistening it for a moment with

water; the same bit of gold-beater's skin admits of being again and

again reapplied in the same manner.

The other circumstances which render the eschar unadherent will be

mentioned hereafter. In the mean time the fact stated p. 6, will

sufficiently establish the propriety of treating distinctly of the

adherent eschar.

I now proceed to mention some other effects of the application of the

caustic. The first is that, in cases in which there would be much and

long continued irritability and pain, as in superficial wounds along

the shin, all this suffering, and its consequences in disabling the

patient, are completely avoided. A blush of inflammation forms around

the eschar, but this gradually subsides without any disagreeable

consequences, and the inflammation which would otherwise have been set

up is entirely prevented by the due formation of the eschar.

If inflammation be previously established, it is increased, at first,

by the application of the caustic. But if this inflammation be not

severe, and if the eschar remain adherent, all inflammation, both that

induced by the application of the caustic, and that existing

previously, entirely subsides. When the previous inflammation round

the ulcer is considerable, however, the application of the caustic

would induce vesication, and it should in such a case of course be

avoided, and another mode of treatment to be described hereafter must

be adopted.

I would introduce in this place some observations on the comparative

effects of healing by eschar and by scabbing. On the subject of

scabbing I must refer my reader to the well known work of Mr. John

Hunter. The advantage of healing by eschar over that by scabbing is

quite decided. By comparative trials, I have found that whilst the

scab is irritable and painful, and surrounded by a ring of

inflammation, the adherent eschar is totally free from pain and

inflammation; and that whilst the scab remains attended by

inflammation and unhealed, the eschar is gradually separating, leaving

the surface underneath completely healed. To these observations I may

add that the success of the plan of healing by eschar is infinitely

more certain as well as more speedy than that by scabbing.

I shall, in conclusion, briefly recapitulate the advantages of this

mode of treatment. In the first place, it will be found far more

efficacious and speedy than any other; secondly, it has the great

advantage of saving the patient much suffering and inconvenience; and

thirdly, it renders the repeated application of dressings and

ointments quite unnecessary. Its utility is extremely great,

therefore, where the time of the poor, the expense of an

establishment, and the labours of the medical officer, as well as the

sufferings of the patient, require to be considered; and it will I

imagine be found of no little advantage, in all these respects, in

many cases which are incident to the soldier and sailor.

II. ON THE UNADHERENT ESCHAR.

The eschar is generally adherent in cases of recent injuries, and in

small ulcers, when they are nearly even with the skin and attended by

little inflammation. In other cases the eschar is too apt to be

unadherent, and this arises from the formation of pus or of a scab

underneath.

If the eschar be unadherent by subjacent pus, it may be ascertained in

the space of from twelve to twenty-four hours; the centre is generally

observed to be raised and to yield to the pressure of a probe;

sometimes the subjacent fluid has partly escaped by an opening at the

side of the eschar.

When a scab forms underneath the eschar, which does not happen except

the fluid has been allowed to remain too long under the eschar without

being evacuated, there are pain and some inflammation, the eschar does

not separate, but remains long over the sore, and there is no

appearance of healing.

When it is ascertained that there is fluid underneath the eschar, a

slight puncture is to be made by the point of a penknife, the fluid is

to be gently pressed out, and the caustic is then to be applied to

the orifice thus made. The same plan is to be adopted if the fluid

ooze out at the edge of the eschar; it is to be fully evacuated by

pressure, and the orifice is to be touched with the caustic. The

healing process goes on best however when the orifice is in the centre

of the eschar. After this treatment the eschar occasionally remains

adherent, but more frequently the fluid requires to be evacuated

repeatedly, and this should be done every twelve hours, or once a day,

according to the quantity of fluid formed, taking care that the eschar

be not needlessly separated by allowing the fluid to accumulate

underneath. If, from accident, the eschar is separated before the sore

be healed I would reapply the caustic. At length the eschar becomes

adherent, and in due time begins to peel off, leaving the surface

healed.

In every case in which the eschar does not separate favourably, I

begin to suspect the formation of a scab underneath, in which case the

whole must be removed by the application of a cold poultice for two or

three days; this has not only the effect of removing the eschar but of

allaying any inflammation or irritation; afterwards the caustic must

be reapplied as before.

The gold-beater's skin is more useful as a protection to the

unadherent than to the adherent eschar, as the former would be more

liable to be torn off by accident than the latter. The gold-beater's

skin must be removed in the manner already described, whenever the

subjacent fluid is to be evacuated, and must be reapplied after

touching the orifice with caustic.

The pain experienced on the application of the caustic is greater or

less according to the sensibility and size of the wound. In small

wounds it is trifling, and of short duration; it is more severe in

recent wounds than in ulcers; it soon subsides in every case, and

then the patient enjoys greater ease than would be experienced under

any other mode of treatment. Little or no pain is caused on applying

the caustic after evacuating the subjacent fluid of an unadherent

eschar. Altogether the pain inflicted by the caustic is far less than

is generally imagined, and forms scarcely an obstacle to its

employment.

It may be proper, in this place, to notice such circumstances as

render the employment of the caustic improper or inefficient. It is

improper to employ the caustic when the ulcer is too large to admit of

the formation of a complete eschar; or when it is so situated as to

render it impossible that the eschar should remain undisturbed, as

between the toes, unless, indeed, the patient be confined to his

bed;--or in cases attended by much inflammation, or by much oedema.

I have found no kind of caustic so manageable as the lunar caustic;

and this is best applied in the solid form. I have thought too, that

the newly prepared lunar caustic is more apt to dissolve on being

applied than that which has been longer made and more exposed to the

air; the latter is therefore to be preferred.

III. ON THE TREATMENT BY ESCHAR AND POULTICE.

In many cases in which it is impossible to adopt either the mode of

treatment by the adherent or the unadherent eschar, it is of great

utility to apply the caustic first and then a cold poultice made

without lard or oil: this plan is particularly useful in cases of

punctured wounds attended by much pain and swelling, and in cases of

recently opened abscesses. By this application the pain and swelling

are much subdued and a free issue is secured for the secreted fluid;

and in no case have I seen the original inflammation increased by it.

It is generally necessary to repeat the application of the caustic

every second or third day, or every day if the inflammation and

swelling of the part be considerable, and the cold poultice may be

renewed about every eight hours. At length, however, the inflammation

having subsided, the attempt may be made to form an adherent eschar.

I have seen many cases, in which, by this mode of treatment, much

suffering and perhaps the loss of some of the smaller joints have been

prevented, particularly cases of deep seated inflammation of the

fingers, which, having been neglected, have issued in severe

inflammation, abscess, and terrible fungous growths. In these cases it

is not only necessary to apply the caustic to the surface of the sore,

but in every cavity or orifice which may be formed by the disease.
