2581. In Infantile Cholera, Dr

Dewees states that no remedy is so prompt and so certain as an injection of warm water, in which is dissolved a large teaspoonful of Salt. This strength is for a child of one year old; the quantity should be increased in proportion, according to the age of the child. Should it be frequently returned, he advises it to be repeated and persevered in, until it bring away a fAecal or bilous discharge, after which the vomiting, &c., will cease. So decided and effective is this simple plan, that Dr. Dewees states that he has seen it above a hundred times relieve entirely, without the aid of other remedies.

2582. In Bilous Diarrha, Salt Is Advised By Trousseau

Its object is not so much to check the diarrha as to alter the composition of the blood, producing occasionally a primary, but more frequently a secondary alteration upon the intestinal irritation. From gr. x. to gr. lx., according to the age of the patient, may be repeated three or four times a day.

2583. In Typhoid and other low Fevers, Salt was formerly administered with the view of counteracting putridity, a term which has now, in a great measure, been abandoned, and with it, the means which were employed to correct or destroy this tendency. Dr. Copland's * observations on this subject are worthy of careful attention. That the Chloride of Sodium, he observes, is necessary to the healthy state of the blood, cannot be doubted; it therefore follows that the privation of it for a number of days, during the treatment of fevers, will materially favour the morbid condition which the fluids assume in the advanced stages. He thinks it probable that the common Salt, taken so abundantly with our food, after having produced the effects arising from its neutral state, becomes decomposed in the system, and that each of its constituents performs ulterior offices in the economy that are necessary to the continuance of health, and enters into new combinations, produced by the actions of the respective organs on the circulating and secreted fluids. If this view be just, the insufficient supply, or the privation of this Salt in the early stages, whilst the discharge of it continues by the excretions, will cause a deficiency of it in the advanced periods of fever, and will give rise to further changes, both in the circulating and in the secreted fluids. In conformity with this opinion, a modification of the medical and regimenal treatment usually recommended in typhoid fevers, should be adopted. It is not improbable, he adds, that the evils resulting from a total privation of a substance so necessary to the healthy discharge of the functions as the Chloride of Sodium, would have been more generally manifested in these diseases, if other substances (as Chlorinated Soda, &c), acting somewhat similarly upon the blood and on the system, had not been commonly employed in the treatment of them.
