In the plastic or pseudo-membranous form of bronchitis it is an object of much importance, in the first stage, to limit the amount of plastic exudation, and later to hasten the loosening and disintegration or discharge of such layers of false membrane as may have formed on the bronchial mucous surface. For these purposes alterative doses of calomel may be given alternately with the doses of the formula containing the liquor ammonii acetatis already given (see Formula No. 1) during the first twenty-four hours, and subsequently pretty full doses of the iodides of sodium or potassium or of the bicarbonates. In acute cases in children, when the symptoms indicate that the false membrane is loosening and the dyspnoea is great, an emetic that will induce prompt and free vomiting may hasten its expulsion and afford much relief. In the cases which have been described as rheumatic bronchitis of the more acute or active grade I have seen the most prompt and satisfactory degree of relief follow the administration of the following combination of remedies in the early stage: {181} No. 5. Rx. Sodii salicylatis, (25.00 grams) drachm vj; Glycerinæ, (15.00 c.c.) fluidrachm iv; Vini colchici radicis, (25.00 c.c.) fluidrachm vj; Syrupi scillæ compositi, (45.00 c.c.) fluidounce iss; Tincturæ opii camphoratæ, (60.00 c.c.) fluidounce ij. M.--Sig. Give 4 cubic centimeters (fluidrachm j) every three or four hours in a little additional water. In several cases in which this grade of inflammation was located chiefly in the smaller bronchi, causing very distressing and persistent dyspnoea, I have found an equal mixture of the wine of colchicum-root and the acetated tincture of opium, given in doses of 25 to 30 minims every three hours at first, to afford more relief than any other remedies I could use; and after some degree of relief had been obtained, by lengthening the interval between the doses to four or six hours and continuing it a few days, all the symptoms were removed. When the disease occurs in old persons, accompanied by severe paroxysms of coughing and only a scanty and very viscid mucous expectoration, much benefit may sometimes be derived from the use of the carbonated alkalies, such as the carbonate of ammonium or bicarbonate of sodium, dissolved in an equal mixture of the fluid extract of the Phytolacca decandra, liquor ammonii acetatis, and camphorated tincture of opium, in such proportions that the patient will get 3 decigrams (gr. v) of carbonate of ammonium in each dose of the mixture.
