Sources: Hydriatic Treatment Of Scarlet Fever In Its Different Forms

As the patient should have a constant supply of pure air for his lungs,

so he should also have _plenty of pure cold water_ for his stomach, to

allay his thirst and assist in diminishing the heat of fever, and in

eliminating the morbid poison from his blood. Though cold, the water for

drinking should not be less than 48 or 50 deg. Fahrenheit. Whenever there is

ice used for cooling the water, the nurses should be very careful not to

let it become colder, than the temperature just indicated, except in

typhoid cases, when the stimulating effects of icy cold water and ice

may prove beneficial.
