By far the largest number of deaths in febrile diseases result from the accumulation in the system of poisonous substances, which paralyze or destroy vital centers and organs. Therefore it is necessary to eliminate the morbid products of inflammation from the organism as quickly as possible.
This also is accomplished most effectively and thoroughly by the application of wet packs. As they draw the blood into the surface and relax the minute blood vessels in the skin, the morbid materials in the blood are eliminated through the pores of the skin and absorbed by the packs. That this is actually so is verified by the yellowish or brownish discoloration of the wet wrappings and by their offensive odor.
One of the main causes of constipation in febrile diseases is the inner congestion and fever heat. Through the cooling and relaxing effect of the packs upon the intestines, this inner fever heat is reduced, and a natural movement of the bowels greatly facilitated.
If constipation should persist in spite of the packs and cooling compresses, injections of tepid water should be given every day or every other day in order to prevent the reabsorption of poisonous products from the lower colon. But never give injections of cold water with the idea of reducing fever in that way. This is very dangerous and may cause fatal collapse.
