Of the Treatment of the Inflammatio Assuefacta.
After the inflammatio valida has continued for a considerable time, if neither suppuration, nor any other termination be induced, it is very apt to be converted into the state which has been called passive inflammation, or which, on account of its most frequent cause, I have called the inflammatio assuefacta. This action is, in several respects, different from the acute inflammation, and resembles it only in its general appearance. It may therefore, in one respect, be considered as a termination of inflammation, being, strictly speaking, a new action, or spurious inflammation.
This action succeeds the acute inflammation, sooner or later, in different places; and, when once induced, each succeeding inflammation of the same part is apt very quickly to terminate in the same condition; or, if the renewal of the inflammation be very frequent, this is at last induced without any previous acute inflammation.
A state somewhat similar to this, if not exactly the same, precedes acute inflammation, as well as follows it; for, during the period which intervenes betwixt the first formation of the action and its perfection, the part remains in this state. We can sometimes observe the augmentation and diminution of the redness and pain during the systole and diastole of the arteries; and, by the use of the same remedies which cure the inflammatio assuefacta, we can sometimes prevent the farther progress of the disease.
Thus, pepper boiled in milk, is frequently used by the country people as a cure for cynanche, during its incipient stage.
Bleeding, saturnine applications, and the other remedies which are useful in the inflammatio valida et acuta, are hurtful here, and increase the disease.
The agentes similes, on the contrary, are useful, and may be used internally, or topically.
Internally, the bark, wine, and opium, with good diet, ought always to be employed, if the part affected be very delicate, and sympathise greatly with the constitution, or if the extent of the disease be great.
Locally, stimulating applications are the proper remedies; and the strength and nature of these must depend upon the natural or acquired delicacy of the part.
When the skin, or cellular substance, is affected with the inflammatio assuefacta, spirit of wine by itself, or with the addition of a little camphor, is a very useful application.
When the skin is not directly affected, but only the parts immediately below it, as, for instance, the muscles in chronic rheumatism, or the articulating surfaces of joints, we may sometimes, by applying cloths dipped in laudanum, or strong diffusion of opium, propagate, from the surface to a certain distance, the narcotic action, and alleviate the disease; but, most frequently, we are obliged to trust entirely to the effect of the sympathy of equilibrium, diminishing the action of the internal parts, without any considerable change of nature, by increasing that of the surface. Blisters and rubefacients, such as volatile linamentol. terebrinth. cum camphora, &c. are the remedies for this purpose.
The inflammatio assuefacta, when it affects delicate parts, covered only with a thin skin, such as the throat, forming one of the most frequent species of cynanche, is cured by gargling with port wine, infusion of capsicum, and similar remedies.
When it affects the eyes, the use of stimulating and opiated preparations have been long in use. The following is one of the best:
R. Vini Albi uncias duas.
Opii drachmam.
Pulv. Gall. scrupulum. Macera per dies tres dein cola.
A drop or two of this may be let fall into the eye three times a day.
Electricity is recommended in the cure of this kind of inflammation; but this, as well as heat, are doubtful remedies; for both seem to increase actions without changing them, except in so far as the change depends upon an increased degree. Cold, on the other hand, lessens the power of recovery, if carried to any great degree; but, when slight, it assists the operation of other remedies, by lessening the performance of the existing action, which is morbid. All applications, therefore, ought in general to be a little below the temperature of the part.
Whenever an inflammation does not manifest a tendency to any other termination, but continues stationary, or perhaps becomes worse, under the use of the remedies which we employ for the cure of the inflammatio valida, we may consider that this action (or the inflammatio assuefacta) has taken place, and that the nature of our applications must be changed. Bark and wine, with anodynes, may be given internally, whilst, if the situation of the part permit, suitable applications must be made to it. By continuing this treatment, we frequently resolve the inflammatio assuefacta; but, occasionally, it becomes again converted into the true acute inflammation, in which case the continuance of the same remedies will do hurt. The appropriate local remedies, such as cold, saturnine preparations, &c. must be had recourse to, if the part be external, whilst, if the pulse become hard, and more frequent, or fuller, general remedies, such as bleeding in small quantity, may be useful; but both local and general remedies must be used with moderation, and pushed only a certain length, otherwise we defeat our intention, and again speedily induce the inflammatio assuefacta, by interfering with the powers of recovery. If this happen, we must again have recourse to the proper remedies.
