COLD. Syn. Fri′gus, L. The privation of heat. The term is also applied to the sensation and effects which this privation produces.
When the body of an animal is immersed in an atmosphere at a temperature below the healthy standard, a sensation of coldness is experienced, produced by the passage of the caloric or heat of the body into the colder medium. If this extraction of caloric exceeds the quantity produced by the vital system, the temperature of the body decreases, until it sinks below the point at which the functions of life can be performed. This declination of the heat of the body is gradual; the extreme sensation of coldness changes into a disinclination for voluntary motion; next comes on drowsiness, followed by numbness and insensibility. At this point if the sufferer is not rescued, and remedial measures had recourse to, death inevitably and rapidly ensues.
The prevention of the effects of cold consists in the use of ample food and clothing proportioned to the inclemency of the weather, the exposure to be endured, and the habits of the wearer. The circulation of the blood should be promoted by active exercise, and any disposition to sleep shaken off by increased bodily exertion. The principal endeavour should be to keep the extremities and chest warm, as, if this can be accomplished, no danger need be feared.
In cases of asphyxia produced by intense cold, the patient should be laid in a room remote from the fire, and bathed with cold salt-and-water, or water to which some brandy or vinegar has been added; after which the body should be wiped dry, and friction assiduously applied by the hands of the attendants (warmed); as many operating at once as can conveniently do so. Gentle stimulants should be administered by the mouth, and the bowels excited by some mild, stimulating clyster. The lungs should also be inflated, and an effort made to re-establish the respiration. As soon as symptoms of returning animation are evinced, and the breathing and circulation restored, the patient should be laid in a bed between blankets, and a little wine-and-water administered, and perspiration promoted by heaping an ample quantity of clothing on the bed. Should the patient have suffered from hunger as well as cold, the appetite may be appeased by the administration of a limited quantity of light food, taking especial care to avoid excess, or anything indigestible or exciting, &c. See Asphyxia, Bronchitis, Catarrh, &c.
