Gastro-intestinal disturbances are met by ordinary medical means. Vomiting, for example, can sometimes be checked by effervescing drinks, such as citrate of caffein, or by dilute hydrocyanic acid and bismuth.
The only value of the nitrites is when the blood pressure is high and the nitrite action is desired on that account. Coffee or caffein often causes these hearts to become irritable; it certainly raises the blood pressure, and therefore is not generally advisable. Both tea and coffee should generally be prohibited. During the acute faint attack, camphor is one of the best stimulants.
It has never arrested attention as a distinct grade of the article, but it contains more coffee or caffein to the pound than any berry known to commerce. It is the smallest, heaviest and darkest green of any coffee that comes to our market from Brazil and may be known by these traits.
Caffein: This should not be given or allowed, even in the form of tea or coffee, to patients who have valvular lesions with perfect compensation, as it is a nervous and cardiac stimulant and may cause a heart to become irritable. It raises the blood pressure slightly, acts as a diuretic, and hence is often of great value when used medicinally. It should be ranked as a stimulotonic to the heart.
It is a crime to present caffein as a soda fountain beverage to children and young persons when the excitement of the age is such as already to overstimulate all nervous systems and all hearts. A considerable majority of persons over 40 learn that they cannot drink tea or coffee with their evening meal without finding it difficult to sleep. Such patients, of course, should omit this stimulant.
Cardiac Tonics: Digiralis, strophanthus, caffein, strychnin. 2. Cardiac Stimulants: Camphor, alcohol, ammonia. 3. Vasodilators: Nitrites, iodids, thyroid extract. 4. Cardiac Nutritives: Iron, calcium. 5. Cardiac Emergency Drugs: Ergot, suprarenal active principle, pituitary active principle, atropin, morphin, and also some of the drugs already mentioned.
Part of the taste of these beverages is due to the caffein, but the special flavor of each is given by spicy oils and other substances which it contains. Caffein acts as a mild stimulant both to the nervous system and brain, and to the heart; as is shown by the way in which tea or coffee will wake us up or refresh us when tired, or, if drunk too late at night, keep us from going to sleep.
Caffein may be used as a drug as well as given in coffee and tea. Atropin may be of value in some forms of hypotension. At times with a low systolic pressure, but a relatively high diastolic pressure, nitroglycerin is valuable. More or less actite hypotension may occur in hot weather or with overheating, often termed heat exhaustion.
On the other hand, if the diastolic is being raised by an increased venous pressure from a failing heart, digitalis, strychnin and caffein may be of benefit in lowering the diastolic as well as raising the systolic. However, if there is a high systolic and a low diastolic pressure, vasodilators are often contraindicated.
Therefore when a heart has serious lesions, whether of the myocardium or of the valves, with compensation only sufficient, the action of caffein in any form is contraindicated.
