49 Put half an ounce of sago into an enamelled saucepan with three-quarters of a pint of cold water, and boil gently for an hour and a quarter. Skim when it comes to the boil, and stir frequently. Sweeten with a dessertspoonful of sifted loaf sugar. If wine be ordered, two dessertspoonfuls; and if brandy, one dessertspoonful.
50 Half an ounce of the best tapioca to a pint and a quarter of new milk. Simmer gently for two hours and a quarter, stirring frequently; sweeten with a dessertspoonful of sifted sugar.
51 Take three tablespoonfuls of lentil flour, a salt-spoonful of salt, and one pint of water. Mix the flour and salt into a paste with the water and boil ten minutes, stirring (Food for the Invalid, Fothergill and Wood, New York, 1880).
The diet for convalescence should be controlled by the physician until the patient has been well for at least two weeks. Liquid preparations give place to fine hominy, corn meal or oatmeal porridge, with milk. Then bread or crackers may be given, the intervals between the meals increasing to three or four hours. Raw oysters, sweetbreads, tender rare steak or mutton finely divided and well masticated, rice, and ripe peaches, succeed the simpler diet. Much saccharine, starchy, or fatty food is to be avoided for at least two weeks after entire recovery.
When the indications derived from the study of the cause have been acted on, and the patient has been placed under a rigid discipline of rest and diet, the treatment of symptoms comes next in order.
In mild cases, where the cause has been irritating ingesta, diet may relieve the symptoms in a short time without medicine. If diarrhoea with slight colicky pains and flatulence continue after a few hours, a mixture holding in suspension subnitrate of bismuth, with five drops of the deodorized tincture of opium in each dose, or a pill of lead and opium, will suffice in a short time to give relief. In severer attacks the fever heat may mount to a high point, giving great distress to the patient. If a temperature of 103° to 104° F. is reached—which is not unusual in children—a warm bath is a sedative and antipyretic remedy, or a bath of 95° can be gradually cooled down to 75° or 65° F.—a procedure which will bring down the body-heat two or three degrees. A substitution for the bath is sponging with cool or cold water, to which vinegar or bay rum may be added; or towels wrung out of cold water can be applied to the trunk and extremities (Ringer) with a very happy effect.
Quinia can be used antipyretically in full doses, dissolved in dilute hydrochloric acid. Pills, especially the sugar- or gelatin-coated pills, should not be given, as they irritate the mucous membrane whether they are dissolved or not. In diarrhoea quinia pills often pass unaltered.
Flatulence, eructations of gas, and borborygmi are controlled by strict diet according to the rules given. Bismuth subnitrate or subcarbonate unites with sulphuretted hydrogen and absorbs it. The alkalies, sodium and potassium bicarbonate, sodium hyposulphite, the aromatic spirits of ammonia, either relieve acidity or prevent fermentation and the development of gas. A satisfactory formula for the early stages of intestinal catarrh is one containing bismuth subcarbonate, sodium bicarbonate, aromatic spirits of ammonia in water or cinnamon-water. When the abdominal distension is great enough to be a cause of distress, external cold—dry cold—is the best, applied with a rubber bag filled with cracked ice or ice-water; it causes absorption of gas. Abdominal compression with a bandage may be of some service also. Mineral acids, especially the dilute hydrochloric acid, by affording aid to the digestion prevent acid fermentation.
Diarrhoea is the central symptom and the best standard by which to measure the intensity of the catarrh and its progress. But it is only a symptom, and the mind ought to be directed to the lesion and not to it. Having the cause in view, the object in all cases is to allay the inflammation. This done, the diarrhoea decreases, then ceases. Shall the effort be made to check the discharges, or shall they be allowed to continue? The evacuant plan of treatment has been advocated, on the ground that the purgative, by increasing intestinal secretion, relieves the congestion of the intestinal blood-vessels and leaves the membrane in a better state than before.52 But inasmuch as a purgative only acts by bringing about an intestinal hyperæmia and catarrh, there is no good reason for, and many reasons against, treatment by evacuation.
