REFRIGERANT APPLICATIONS.
A freezing mixture which will reduce the temperature to 4° is made by mixing equal parts of salt and pounded ice. The ice and salt should be stirred together very quickly and applied at once to the part to be frozen. Two parts of dry snow and one of salt make an equally good mixture. Freezing is more conveniently performed by the rapid evaporation of ether or rhigoline.
Freezing is a useful process in numerous cases. By its use, excrescences—as warts, wens, and polypi—fibrous tumors, and even malignant tumors, as cancer, may be successfully removed. Small cancers may sometimes be cured by repeated and long-continued freezing. Their growth may certainly be impeded by this means. Felons, if treated early in their course, may be cured by two or three freezings.
For freezing a felon, place the finger in a mixture ice and salt, or surround it with cotton, saturate the cotton with ether or rhigoline, and blow it very strongly with a pair of bellows. This is a very good method when an apparatus for producing a fine spray is not at hand. The latter instrument facilitates the freezing very much if used with the bellows.
No harm results from repeated freezing if proper care is used in thawing the frozen parts. They should be kept immersed in cool water, or covered with cloths kept cool by frequent wetting with cold water, until the natural feeling is restored.
The application of ice is found extremely serviceable in many inflammatory diseases, and in some nervous affections. In inflammation of the brain, the ice cap is of inestimable value. Ice applied to the spine will check the convulsive spasms of chorea and hysteria when other remedies fail. In putrid sore throat, or malignant diphtheria, ice is a sovereign remedy. It should be applied to the neck externally, and held in small bits in the mouth. Small bits swallowed will sometimes relieve the pains of gastralgia.
Rubber bags are very convenient for applying ice or iced water; but their place can be very well supplied by dried bladders filled with pounded ice. The ice cap is a double head cap stuffed with pounded ice.
Some physicians recommend the application of ice to the spine in cases of congestive chill and paralysis, and in inflammation of the stomach, kidneys, uterus, and other internal organs. The real worth of such applications in these cases has yet to be determined by careful and repeated observations. We would not recommend an unskillful person to attempt to relieve a violent ague chill by rubbing ice on the patient’s back, and we have some fears that a very skillful operator would hardly succeed to his entire satisfaction and that of the patient.
The snow bath, applied by rubbing the part vigorously with snow, is a useful application for restoring the circulation to frosted parts. In cases of extreme chilling or absolute freezing, there is perhaps no better remedy. Powdered ice may be used when snow cannot be readily procured.
