OBSERVATIONS
THE PATHOLOGY AND TREATMENT OF CHOLERA. By BAMLET W. Assistant
SWITZER, F.R.C.S.L,
Surgeon,
Bengal Abmy.
offering this paper for the perusal of my Medical brethren frankly state, at the outset, that I have no new or startling theory to propound, nor have I any infallible plan of treatment to recommend. My object is solely an endeavour to establish the pathology of cholera on a correct basis, believing that, until this is done, the treatment of the disease will never be satisfactorily reduced to plain rules; for, I grieve to say, empiric remedies suggested by men outside our profession?and who can have no possible knowledge either of the disease they profess to cure or the frame which is the subject of that disease?too often find support from the public, until sad experience has taught them the wortlilessness of what common sense in the beginning would have equally shown. Some years ago, a very eminent and learned clergyman of a mathematical turn of mind took to thinking about cholera, and, deeming that, in his study, he could by a logical process arrive at a specific, crammed himself with the symptoms of the disease. Amongst others, he found that cholera patients sometimes suffered from clonic spasm, and with, I suppose, some dim shadow of Si nilia similibus curantur floating before his brain, he rushed to the conclusion that strychnia was the long-sought-for panacea. Some experiments on frogs confirmed this idea; and it was given to the world,?need I say with what result ? The numberless drugs, the most opposite in their effects, which have from time to time been used by their warm supporters, quinine to quassia, vinegar to verdigris, down to the last absurdity which was presented to the French Academy of Sciences in October 1865, as an 'infallible receipt,' viz.,?' That the patient should be enveloped in a blanket of new wool, and made to swallow the wing of a fowl, very hot!' All these are but indications tc us how unsettled is the pathology of the disease ; and that, instead of grasping the few facts certainly known, and by them arguing from effect to cause, the fearful nature of the disease has prompted a wild rush into the boundless prairie of speculation, in the hope that some one will, with a cry of Eureka,' accidentally drop on the hidden treasure we hope for?a specific. The Etiology of the disease I would not be understood to include in the foregone remark, for as speculation, on this point can do no injury to our practical treatment, those disposed for theoretical inquiry may safely exercise their bent in this field.

Cholera, per se, is no more wonderful than the class of malignant typhoid fevers, small-pox, tetanus, syphilis, many of the other ills that flesh is heir to; and as we a case of small-pox, so let us look at one of cholera. In both, there is a period of incubation; in both nature, unaided, attempts to rid herself of the disease ; in both the actual potency or virulence of the blood poison may kill; in both the strength of the or

quicksands, fires the signal gun for the skilful pilot, who, knowing the dangers from previous experience, brings her safely through by avoiding the hidden rock and controlling her movements when facing certain destrucsion, so is the cry for help to our profession that the physician may guide his patient through the quicksands of disease, and past the rock of death, though as powerless to remove that disease himself as the pilot is to lift his ship into mid-ocean. If cholera, then, be not subject to entirely different laws, but equally with other diseases bound to obey some rules, a comparison of two diseases

In small-
stage of incubation which extends
over
many days, and during which time tne subject must be considered as stricken with disease; but as it is unrecognizable in this condition, we are unable to define it as small-pox. The poison lurks, but it is invisible, until the time has come that the system can no longer bear the incubus ; then the effort is made to throw it off by
discharging the poison through the skin, by means of a copious purulent eruption. This is the distinctive feature by which we recognize the disease; and though, in fact, it is the attempted cure, as worked by nature, we call it the disease, only then recognizing its specific character. "We never try to cure small-pox by checking this salutary discharge; we rather encourage it. Knowing well that nature selects for the exodus of the poison the most ready and favorable outlet, in such a case our task is not to cure, but to aid, guide, and control her efforts so often unsuccessful from her own inability to direct them. Putting aside accidental or concurrent causes, death in this disease takes place either primarily from the virulence of the poison itself striking the patient ruthlessly and carrying him off in convulsions

In treating smoll-pox, we act as the sentry over life, challenging the approach of insidious ene-
mies, and endeavouring to guard our charge in the perilous hour of danger, while that danger, so often incapable of any alleviation by us, hangs over, or until it passes by. A rational solution of the Pathology of cholera may be assisted by looking at the disease in a similar way to that in which smallpox has been glanced at. A stage of incubation in cholera is believed in by many, and some state that they have been able to detect cholera in the countenance many hours before its presence was shown by other symptoms ; this, I think, if? doubtful, although some well-authenticated cases -are

It is rare that the potency of the poison kills without the preservative effort, but there is doubt of its occurrence, predisposing conditions of access and process conducing to it. In the more common struggle between the victim and the disease, the fcliminative process is set up; and in cholera this consists in the rapid expulsion from the system of the poison dissolved, suspended, or

"Why cholera poison should select water as its carrier, we are as unable to say as why a pustular eruption through the skin should be the chosen path of exit for the poison of variola; that such is the case, admits of no doubt, for it is well known that inoculation of the pus from a small-pox pustule, or the introduction into a healthy stomach of either the vomit or alvine discharge from a cholera patient, * will in both cases produce the respective disease. Cholera poison then selecting, nc doubt, the best means of leaving the system, seizes on the water of the blcod, and by every channel through which water can be most rapidly got rid of is it poured forth in the effort to save. Stomach, bowels, lungs, skin, all open as flood-gates for this suicidal cure, and the constant vomiting, purging, sweating, and exhalation from the lungs soon reduces the amount of water in the blood to a minimum ; thus, the functions of absorption and assimilation being in abeyance, the cure is as bad as the disease. The blood loses such a quantity of its water that it becomes like clotted gore or tar, and refuses to flow; the lungs are choked, and the weakened heart clogged, so that it cannot pump the stream of life; the strength goes, the eye glazes, the lethargy of death approaches, and all is soon over. Here death is mechanical and begins at the heart; and, if all this be true, it will lead to the conclusion that the patient dies more often from the injuries produced in Nature's attempted cure, than from the excessive killing power of the disease; thus, after a protracted attack during which large quantities of water have been lost, the poison will doubtless have been got rid of completely, and the patient then dies from the weakness produced in the struggle, itmodes chosen.

night;
ready a premonitory stage of cholera, from which but one recovered; or as a predisposing cause, owing to which the disease bad more ready access to the other ? The latter will, I think, be found the true view : and this sporadic diarrhoea, so generally looked upon as the premonitory stage of cholera, has, I believe, no further connection with it than in the fact that, being neglected, it places the individual in the most favourable position to receive the more serious disease. Were we to consider the diarrhoea as a result of the poison already permeating the system, the recovery in the one case would lead us to suppose that either from the diminished potency, or the small quantity of poison present, the diarrhoea was sufficient to remove it; while, in the other, the attempted elimination being checked, the poison generated in excess and resulted in cholera. This would be a most dangerous doctrine to countenance ; for it would lead to the neglect of this premonitory diarrhoea, or to our hesitating to control it, either of which courses would be most fatal. We may therefore reasonably doubt whether there is any premonitory stage to cholera, though we cannot doubt that there is a predisposing disease. II. Established.?Sometimes, without any predisposing diarrhoea the disease is abruptly ushered in, or the diarrhoea continuing unchecked or uncheckable, it culminates in true cholera, the characteristic mark of which is the rapid expulsion from the From all analogy we learn that it must be the fittest process which is selected for discharging the poison, but we equally know that a fatal result will follow from the absence of the water. Our difficulty is thus apparent. If this be Nature's method of cure, any attempt to control the
system of its contained water.
simply opposing the means selected for the safety know, the poison can be got rid of in no other way, and it3 retention will as surely kill. The truth of all this is proved at the bedside, for our attempts to control the watery purgation, or end the constant emesis, are generally useless; they go on unchecked,, whilst any poison remains to be rejected ; but when this is accomplished they quietly cease of themselves. We know that, in the majority of fatal cases, all purging and vomiting cease some hours before death, and with their cessation the disease has also terminated ; the patient might then be considered as cured of cholera, and the battle successfully fought, were it not for the fatal drain the victory has caused with the watery

Collapsed.?I have said above that the disease, per se, discharges ; and if this be true, collapse must be looked on more as tiie result than as any part of the disease itself.

fluid, and it may be fairly questioned -whether the sudden and rapid extraction from the blood of a comparatively small quantity of water would not produce this quick depression and death, when, the slower withdrawal of a much larger quantity is more gradually followed by a similar result. If this be not the explanation of such deaths, it must be found in the supposition that a l?rger portion of the poison finds entrance and is of itself sufficient to kill, or that one subject is less able to bear up against the same quantity and of poison than another. As a rule, the more healthy a is the better able is he to encounter the disease with success, and when it is spent, the better chance was the vis mcdicatrix naturcc to bring him round. The apparently random

selection it makes of its victims is one of the curious vagaries of the disease?the strong being often taken and the weak left. Again, those who fear cholera always get it when brought in contact with it; those who do not fear it rarely suffer. Established cholera having been present for some time and the discharge of water

the nervous centres of course participate in Ihe general effects of the disordered circulation equally with the other parts of the body.

There are
no
facts at
present known which could warrant the conclusion that cholera is in any way connected with nerve lesion. It is far more a disease of the circulatory apparatus, for that is the first affected by the established disease ; and any nervous phenomena can all be traced to this primary disturbance. Collapse, then, is not otherwise connected with cholera than as a result; and the bearing this in'mind will lead us to the healthful consideration that this,
the most fatal period of the attack, ought, from the disease having already spent itself, to be the most hopeful. The adage " Whilst there is life there is hope" is peculiarly appropriate here ;
for those who have seen much of cholera must have witnessed instances of recovery little short of miraculous. Men moribund have been snatched from the jaws of death most wonderfully, by some sudden impression ; the most opposite means have produced this, such as the emotions of joy and fear, brandy, champagne,
electricity, fire, &c.; thus showing that the disease having left, fillip given to the system sufficient to re-establish the absorptive function, will save the life. The stomach, bowels, and skin may continue to expel water, even after all the poison is got rid of, merely from the original impression remaining, or what would correspond with inertia in mechanical force ; and this absolute waste may go on for a time during collapse, until, by some counter-impression, it is removed. We do not expect to succeed in restoring a drowned person while submerged, nor ought we to expect we can prevent collapse continuing, while the system is still expelling water. We resuscitate the apparently drowned, by restoring what is lost?air to the lungs and heat to the body. So ought we to recover the collapsed patient by the supply of water to his blood. As I fear the continuance of thjs paper would demand more space in a single number of the Indian Medical Gazette than it might be convenient to surrender, I will defer the further consideration of the subject to a future occaany

fluid, and it may be fairly questioned -whether the sudden and rapid extraction from the blood of a comparatively small quantity of water would not produce this quick depression and death, when, the slower withdrawal of a much larger quantity is more gradually followed by a similar result. If this be not the explanation of such deaths, it must be found in the supposition that a l?rger portion of the poison finds entrance and is of itself sufficient to kill, or that one subject is less able to bear up against the same quantity and of poison than another. As a rule, the more healthy a is the better able is he to encounter the disease with success, and when it is spent, the better chance was the vis mcdicatrix naturcc to bring him round. The apparently random
quality
man
selection it makes of its victims is one of the curious vagaries of the disease?the strong being often taken and the weak left. Again, those who fear cholera always get it when brought in contact with it; those who do not fear it rarely suffer. Established cholera having been present for some time and the discharge of water

the blood

circulate with the rapidity necessary for its oxygenation. Carbonized blood then slowly flows through the system, and cold is the result. That this cold is in any way
unable
to
primarily connected with
nervous
influence,
I do not believe, but
the nervous centres of course participate in Ihe general effects of the disordered circulation equally with the other parts of the body. The poison of cholera, whatever it maybe, does not affect the sensorium; the clear intellect neither excited nor depressed shows that the brain, the great nervous centre, is the least and the last affected; not until death approaches does the cholera patient
perfect self-possession; there is no delirium here, no long as the blood remains tolerably pure, and the heart can pump the scanty supply the brain requires, reason reigns unharmed. Pain, the greatest evidence of nervous activity, is acutely felt by the cholera patient, who will feel and call out for the reever

There are
no
facts at
present known which could warrant the conclusion that cholera is in any way connected with nerve lesion. It is far more a disease of the circulatory apparatus, for that is the first affected by the established disease ; and any nervous phenomena can all be traced to this primary disturbance. Collapse, then, is not otherwise connected with cholera than as a result; and the bearing this in'mind will lead us to the healthful consideration that this,
the most fatal period of the attack, ought, from the disease having already spent itself, to be the most hopeful. The adage " Whilst there is life there is hope" is peculiarly appropriate here ;
for those who have seen much of cholera must have witnessed instances of recovery little short of miraculous. Men moribund have been snatched from the jaws of death most wonderfully, by some sudden impression ; the most opposite means have produced this, such as the emotions of joy and fear, brandy, champagne,
electricity, fire, &c.; thus showing that the disease having left, fillip given to the system sufficient to re-establish the absorptive function, will save the life. The stomach, bowels, and skin may continue to expel water, even after all the poison is got rid of, merely from the original impression remaining, or what would correspond with inertia in mechanical force ; and this absolute waste may go on for a time during collapse, until, by some counter-impression, it is removed. We do not expect to succeed in restoring a drowned person while submerged, nor ought we to expect we can prevent collapse continuing, while the system is still expelling water. We resuscitate the apparently drowned, by restoring what is lost?air to the lungs and heat to the body. So ought we to recover the collapsed patient by the supply of water to his blood. As I fear the continuance of thjs paper would demand more space in a single number of the Indian Medical Gazette than it might be convenient to surrender, I will defer the further consideration of the subject to a future occaany
sion.
