The existence of polyarthritis, of peri- or endocarditis, of pneumonia or pleurisy, does not contraindicate the cold bathing. If much weakness of the heart obtains, it is well to give some wine or brandy before employing the bath, and perhaps while in it, and the patient should not be kept in the bath until the temperature reaches the norm, for it continues to fall for some time after his removal from the bath. If the temperature fall rapidly 2° to 3° in five or six minutes, remove the patient from it as soon as the temperature recedes to 102° or 101° F. If it fall very slowly, the bath may be continued till the temperature declines to 99.5°, when he should be taken out. Should marked symptoms of exhaustion or of cyanosis arise, the bathing should be at once stopped. After it has been found necessary to employ cold in this way, the thermometer should be used every hour, and if the temperature tend to rise rapidly again, the diligent application of a succession of towels wrung out of iced water and applied to the body and limbs, or of Kibbie's method, may suffice; but should they not, and a temperature of 103° or 104° be rapidly attained again, the cold or tepid bath should be at once resumed. In severe cases of this kind a liberal administration of alcohol and liquid food is generally needed, and it is well to try antipyretic doses of quinia by mouth or rectum, although they are usually very disappointing in these cases. It is admitted that cold baths have in a few rare instances caused congestion of the mucous membrane, pneumonia, pleurisy, and even fatal syncope. This is a reason for the exercise of care and constant oversight on the part of the physician, but hardly an excuse for permitting a person to die in rheumatic hyperpyrexia without affording {68} him at least the chance of recovery by the use of the cold or tepid bath. If delirium and deafness supervene during the employment of the salicylates, it is prudent to suspend their use and take the temperature every couple of hours, as one cannot feel confident that hyperpyrexia may not be impending. Both Caton and Carter have found that the addition of bromohydric acid to the sodium salicylate mitigated or controlled the tinnitus and deafness produced by full doses of that salt.
