3. Bad feeding. The diet should of course be sufficient, for the patient and proper for the disease, but any diet which causes a large amount of gas in the stomach, or tympanites, is harmful to the patient's circulation, to say nothing of any other harm, such as indigestion may do. All of the nutriments needed to keep the body in perfect condition should be given to a patient who is ill; in some manner he should receive the proper amounts of iron, salt, calcium, starch, protein, sugar and water. 4. Intestinal sluggishness. This means not only that tympanites should not be allowed, but also that necessary laxatives should be given. It would be wrong to prostrate a patient with frequent saline purgatives, but the bowels must move at least once every other day, generally better daily; and if the case is one of typhoid fever, they should be moved by some carefully selected laxative, and after the bowels have sufficiently moved, the diarrhea should be stopped by 1/10 grain of morphin, and the next day the bowels properly moved again. 5. Depressant drugs. In this age of cardiac failure, heart depressants of all types, and especially the synthetic products, should be given only with careful judgment, and, never frequently repeated or long continued. 6. Pain. This is one of the most serious depressants a heart has to combat; acute pain must not be allowed, and prolonged subacute pain must be stopped. Even peripheral troublesome irritations must be removed, as tending to wear out a heart which has all of the trouble it can endure. 7. Insomnia. Nothing rests a heart or recuperates a heart more than sleep. Insomnia and acute disease make a combination which will wear a heart out more quickly than any other combination. Sleep, then, must be produced in the best, easiest and safest manner possible. 8. A too speedy return to activity. The convalescence must be prolonged until the heart is able to sustain the work required of it. The treatment of gradual dilatation in acute disease has been sufficiently discussed under the subject of acute myocarditis. The treatment of acute dilatation is practically the same as the treatment of shock plus whatever treatment must coincidently be given to a patient for the disease with which he is suffering. The treatment of shock will be discussed under a separate heading. THE HEART IN PNEUMONIA As pneumonia heads the list of the causes of death in this country, and as the heart fails so quickly, sometimes almost in the beginning in pneumonia, a special discussion of the management of the heart in this disease is justifiable.
