Powders, such as flour, chalk, and camphor, &c., have been applied to the erysipelatous surface, but are of little use, and, by their irritation, frequently prove injurious on the bursting of the vesicles. They are applied, according to some, with the view of cooling the surface, and after all the part may be seen enveloped in folds of flannel. Cold application, such as the spirituous and evaporating lotions, containing vinegar and spirits, liquor acet. ammoniæ, Goulard’s extract, &c., may, in many cases, afford temporary relief, but their use is fraught with the utmost danger; for their direct tendency is to produce metastasis, and if that be to an internal organ of importance, the result is too generally fatal. Or if the erysipelas, on leaving the part originally affected, attack another also superficial, the local treatment has to be commenced anew. If these lotions are to be employed at all in this disease, they must be made tepid. In case of the translation of erysipelas to any important part, blisters may be applied to the surface which it has left, or to any other in the neighbourhood, with the view of recalling the disease to its original and less dangerous situation:[8] the actual cautery has even been recommended. In the great majority of cases, however, such means are unavailing. In Hospital Erysipelas, purging cannot be carried to any great extent with safety, and general bleeding is seldom if ever admissible unless the patients previously robust and in good health, in whom the disease has occurred in consequence of their being conveyed to a distance and during hot weather, after an accident or wound, and in whom the fever is of a violent inflammatory nature. In civil hospitals, the patients are generally in a weak state before the accession of this disease; and in their case, after the stomach and bowels are regulated, stimulants are more requisite. Great attention must be paid to cleanliness, the sores must be frequently dressed, and the same sponges must not be used for different individuals: in order to prevent contamination by the promiscuous use of sponges, it is better to clean the parts around sores with lint or tow, and to destroy immediately such dressings as have been used. The apartments must be well ventilated, and those who are affected with the disease should be separated from the rest of the patients. The local applications will vary according to the particular circumstances of each case. Strong escharotics may be required to clean the surface of the sores, and put a stop to the sloughing. The nitric acid will answer the purpose well, and is less objectionable than some remedies that have been used; such as the arsenical solution, or the red hot iron. OF FURUNCULUS AND ANTHRAX.
