TREATMENT.--There are certain leading objects to be accomplished in the treatment of all grades of inflammation affecting the mucous membrane and connective tissue of the bronchial tubes--namely, _(a)_ to diminish or overcome the morbid excitability of the inflamed part; _(b)_ to relieve the vascular hyperæmia or fulness of blood in the vessels, and thereby limit the amount of exudation or morbid secretion and consequent dyspnoea; _(c)_ to counteract or relieve secondary functional disturbances, such as increased heat and dryness of the skin, diminished renal and intestinal activity, and nervous restlessness; _(d)_ to hasten the removal of such plastic exudations as may have caused thickening and induration of the inflamed structures or formed layers or patches of false membrane on the bronchial surface, and to lessen the tendency to establish a stage of purulent degeneration or suppurative action in the inflamed part; _(e)_ to regulate diet, drinks, exercise, and clothing in such a way as to sustain healthy nutrition and prevent the further action of predisposing and exciting causes. The first three objects to be accomplished belong more particularly to the early stage of acute and subacute attacks, but are present in some degree throughout the whole course of the disease; while the last two belong to the latter stages of the acute and to all stages of the chronic grades of the inflammation. While the foregoing indications to be fulfilled or objects to be accomplished are present in all the various grades and stages of inflammation of the bronchi, the particular means for accomplishing them will be modified by the age and previous physical condition of the patient, the nature of the predisposing and exciting causes, the extent of the disease, and the stage of its advancement; or, in other words, the nature and extent of the pathological changes already accomplished. For instance: the same remedial agents that would be most efficient in relieving the morbid excitability and the vascular fulness of the first stage of acute inflammation in a young or middle-aged and previously healthy, vigorous subject might be positively injurious, or even fatal, if used in the same stage of inflammation in a subject previously anæmic and feeble or debilitated from age or from causes capable of impairing the quality of the blood and favoring a typhoid condition of the system. Consequently, the practitioner who not only sees clearly the objects most desirable to accomplish, but who most judiciously selects and adjusts the means or agents he uses to the special conditions of each patient, will meet with the highest degree of clinical success.
