Solution of Chlorinated Soda. Solution of the Chloride or Hypochlorite of Soda. La-barraque's Disinfecting Solution of Soda. A mixed Solution of Hypochlorite of Soda, NaO, ClO, Chloride of Sodium, and Bicarbonate of Soda. Sp. gr. 1.03. On the addition of an acid, it evolves Chlorine freely.

Med. Prop. and Action. Stimulant, tonic, and antiseptic. Externally, it is a stimulant, astringent, and deodorizer; it is best applied in the form of lotion (fl. drm. j. ad Aq. fl. drs. x. - fl. drs. xv.). As a deodorizer it is of great value, and is eminently useful in correcting and destroying the unpleasant smells, so common in sick rooms, &c.; it is also represented as a disinfectant, but it is far from satisfactorily proved that it possesses the alleged property of arresting the progress of any infectious disease. It is an, antidote in poisoning by Hydrosulphuric Acid, Hydrosulphuret of Ammonia, the Sulphuret of Potassium, and Hydrocyanic Acid. A solution should, if possible, be administered by mouth, and a sponge soaked in the solution should be held to the nostrils. If a person, observes Dr. Pereira,* be required to enter a place suspected of containing Hydrosulphuric Acid, a handkerchief moistened with a solution of the Chloride should be applied to the mouth and nostrils, so that the inspired air may be purified before it passes into the lungs.

2554. Therapeutic Uses

In Aphthous Ulceration of the Mouth in Children, when it assumes a sloughing character, Dr. A. Robertson states that the following is one of the best applications which can be used: -2554 Therapeutic Uses 215 Liq. SodAe Chlor., T. MyrrhAe āā fss., Aq. RosAe fj., Aq. fvj., M. In Mercurial Salivation, in the Ulcerated Gums of Scurvy, in fetid discharges from carious Teeth, in the Sore Throat of Scarlatina, and in all affections of the Mouth attended with a fetid discharge, and requiring a mild stimulant application, the diluted solution (fl. drs. vj. ad Aq. fl. oz. xij.) proves highly serviceable, not only correcting the fcetor, but establishing a healthy action. In Diphtheria, Dr. W. Budd* considers Beaufoy's solution of Chlorinated Soda superior to all other applications. He directs the throat to be thoroughly mopped with it, by means of a camel's-hair brush, three or four times daily. He speaks strongly in its favour both as a curative and as a sanitary agent.

2555. In Ozna, Coryza, and Otorrha, when the discharge is fetid, a diluted solution (xv. - xxx. ad Aq. fl. oz. j.) proves highly useful. It should not be used so strong as to cause pain. Dr. Heron (U.S.), who testifies to its value in Ozna, advises it to be injected while the head is held downward and forward, the breath being at the same time drawn through the nostrils; the fluid is thus brought into contact with the whole of the diseased surface, where it may be retained as long as is necessary.

2556. In fetid discharges from the Vagina, whether proceeding from an ulcerated state, or from Cancer of the Uterus, or from other causes, a diluted solution (fl. oz. j. ad Aq. fl. oz. xvj.), used tepid or cold, according to the sensations of the patient, forms an excellent injection. It should be of a strength to cause slight tingling, without pain. It is equally applicable to fetid discharges from the rectum.

2557. When Ulcers assume a phagedenic or sloughing character, or when they are attended by a profuse and fetid discharge, a diluted solution (fl. oz. j. ad Aq. fl. oz. viij.) may be applied with great advantage. Linseed-meal poultices, to which the solution is added (Cataplasma Sodae ChloratAe, ante), also prove useful.

2558. In Typhus and Typhoid Fevers, in Scarlatina Maligna, and in the advanced stages of all Fevers and the Exanthemata, when they assume a Typhoid type, the Chlorinated Soda is a most valuable medicine. "It may be given," observes Dr. Copland, "early in the putro-adynamic variety, when excitement is imperfect or low, and the skin discoloured, or petechias are appearing, and may be continued throughout the disease. But when vascular reaction is considerable, or local determination prominent, particularly in the nervous and exanthematous varieties, this medicine should be withheld until these states are subdued, or about to lapse into the nervous stage. At first, it ought to be prescribed in small doses, so as not to offend the stomach, in from x. to xv. drops of the solution, every three or four hours, in Camphor Julep, or in an aromatic water. As the disease passes into a state of exhaustion, or of manifest putro-adynamia, or when there are a lurid skin, low muttering delirium, stupor, black sordes on the tongue, teeth, &c, the supine posture, unconscious offensive evacuations, petechia?, a disposition to gangrene in parts pressed upon, coma, &c, it should be given in larger doses, or, more frequently, with Camphor, Serpentaria, or other stimulants and tonics. It is productive of great benefit in such* cases, but it should be commenced before these symptoms appear, and should be persisted in, as its good effects are seldom manifest in less than three or four days or more, and it should not supplant the use of Wine, Opium, suitable nourishment, and other means which the case may require. It should also be frequently administered in enemata, and the surface of the body ought to be often sponged with a stronger solution of it in warm water, with the addition of Camphor." M. Chomel and Dr. Graves bear testimony to its value. "It acts first," continues Dr. Copland, " on the tissues with which it is brought in contact, as a gentle stimulant and antiseptic, and is most probably partially decomposed in the digestive organs, and reduced to the state of common salt. In this state it is carried into the circulation, where it supplies the waste of substance that has taken place in the early stage of the disease."

In Scarlet Fever, Dr. Watson* advises a weak solution of the Chloride of Soda as a gargle; and if the disease occur in a child that is not able to gargle, the solution may be injected into the nostrils, and against the fauces, by means of a syringe or elastic bottle. The effect of this application is sometimes most encouraging; a quantity of offensive sloughy matter is brought away, the acrid discharge is rendered harmless, the running from the nose and the diarrhoea cease, and the whole disease is rendered milder.
