Opiates are extremely necessary in the inflammatio debilis, and, in general, require to be given freely.

Soups, and other articles of nourishing diet, are absolutely requisite, and ought to be given in small quantities at a time, but frequently repeated.

By these means, we may frequently resolve the inflammation completely; but, at other times, when we have gained a certain ground, the inflammation terminates in the suppurative action; or, in other words, when the parts have gained more strength, and the action has come more nearly to resemble the inflammatio valida, which has continued for some time, a similar termination takes place. This event cannot, perhaps, in these cases, be prevented, and, although it may occasionally protract the cure, yet it diminishes the danger, making mortification less to be dreaded. The best treatment, in these cases, perhaps, is to continue our usual applications, avoiding warm poultices until the action be fully formed; then moderate heat may accelerate the progress of the abscess toward the surface. The same internal medicines must be exhibited, the anodynes, however, being gradually diminished as the pain (which marks the necessity for their use) abates.

It too frequently, however, happens, that either our remedies fail, or the proper ones are not assiduously and judiciously employed, in which case mortification takes place. This requires the same treatment, in whatever way it is induced, only its progress is, from certain causes, more rapid[70] in one case than in another, and, therefore, requires the more free use of the appropriate remedies; but the general principle is, in every case, the same, and, therefore, I shall here consider the disease indiscriminately, whether it succeeds the inflammatio valida, or debilis; because, in both instances, the case is exactly the same, only, in the first, the weakness which induces mortification, is produced by the inflammation alone, whereas, in the second, it existed to a great degree before the inflammation was excited.

Mortification is to be prevented from succeeding the inflammatio valida, by timely bleeding, and the use of the agentes dissimiles, by which we procure resolution, or at least make the induction of the purulent action more easy. In the inflammatio debilis, it is to be prevented by remedies of an opposite nature.

When, however, these remedies fail, and mortification does take place, our great object must be to prevent it from extending far, and from injuring the system. These intentions are answered by the same remedies which cure the inflammatio debilis; because the local treatment of mortification is merely that of the inflammatio debilis; for it is only the parts which are still alive, or inflamed, which can be acted on by our remedies.

The remedies are either general or topical, and may be considered under these divisions; but both must be used at the same time.

Many of the older writers, proceeding upon the humoural theories, began their treatment of gangrene by bleeding and purging, after which they prescribed theriaca, and other stimulating applications. Some modern authors still adhere, in part, to this practice, and consider the loss of blood to be advantageous in cases of incipient gangrene. Mr. Bell, who is one of the latest writers on this subject, informs us, that, when the “general symptoms of inflammation, particularly a quick, full, or hard pulse, still continue violent, and especially when the patient is young and plethoric, it then becomes absolutely necessary, even although mortification may have commenced, to empty the vessels a little by one general blood-letting,” which, “in such cases, may in reality be considered as an antiseptic; and it does often indeed, in this particular situation of mortification, prove more powerfully so, than all the different articles in general enumerated as such.” If, however, we consider the nature of mortification, and the circumstances under which it is most likely to occur, we must look upon this practice as dangerous, and must be permitted to doubt whether the full hard pulse is to be met with after the commencement of inflammation, or whether the symptoms of the inflammatio valida, (in which alone bleeding is admissible) still continue violent, after one portion of the inflamed part is evidently gangrenous. Is it reasonable to suppose that one portion of the inflamed part shall be already dead, or dying, and that yet the rest shall not have begun to suffer? or that the action shall not have become converted into the inflammatio debilis, (if it were not originally this)? This surely is not the time for bleeding, purging, and debilitating remedies; but the part must be considered as possessing the low inflammatory action, and the patient as requiring suitable remedies. It may indeed be said by some, in favour of bleeding, that the bark, in some instances, does not check the progress of the disease; but it surely does not thence follow, that it does positive injury, and that remedies of an opposite nature are useful.

The Peruvian bark is, in many cases, one of the most useful internal remedies. It was originally introduced into medicine, about one hundred and fifty years ago, as a cure for intermittent fever; and its utility in gangrene is said to have been discovered by its curing this disease in a person who had it combined with ague, and who was taking the bark on account of the latter complaint. For many years after it was known in Europe, great prejudices prevailed amongst physicians against its use, partly on account of its having been improperly administered, but still more because it was so unfortunate as to cure diseases without necessarily either sweating or purging the patient, a fact which could be only ill explained, or rather scarcely allowed to be possible, by the prevailing theories of physic. Accordingly, although the cases in which it had been successful were by no means a secret, and although severals had the courage to employ it, in spite of all speculative arguments, yet neither Dr. Boerrhave, nor his commentator, Van Swieten, thought it expedient either to recommend or prescribe it. Renewing the motion of the stagnating blood by venesection, and the exhibition of trifling remedies, which could scarcely be called cordial, although sometimes dignified with that epithet, together with the external application of ardent spirits, or oil of turpentine, constituted the current practice in gangrene. These prejudices against the bark, which originated in ignorance, and were supported by attention to a foolish theory, continued long; but the want of a better remedy began at last to make them gradually give way, and the success of empyrics who used the bark soon completed their downfal.
