Often the patient recovers consciousness before the doctor arrives; give cold water to drink; never stimulants. (b) _Freezing_--This is a much more serious condition than frostbite, which you have studied, but only because more of the body is frozen and the tissues are frozen deeper. Much more care must therefore be taken to prevent bad effects after the thawing-out process. _Symptoms of Freezing_--1. The patient may or may not be unconscious. 2. The frozen parts are an intense white and are without any feeling or motion. _Treatment_--Send for the doctor at once. 1. Take the patient into a cold room. 2. Remove the clothing. 3. Rub the body with rough cloths wet in cold water. 4. Very gradually increase the warmth of the water used for rubbing. 5. Increase the temperature of the room gradually. 6. When the patient can swallow, give him stimulants. 7. When the skin becomes more normal in color and the tissues are soft, showing that the blood is once more circulating properly through the frozen flesh, cover the patient warmly with hot bottles or bricks outside of the bed clothing, or wraps, and give hot drinks. In using hot water be sure it is not too hot. Dog Bite[3] In the case of the dog bite we have a more or less extensive break in the skin and sometimes a deep wound in the flesh, through which the poison of hydrophobia, which is a living virus or animal poison, may be introduced, to be taken up slowly by the nerves themselves, reaching the central nervous system in about forty days. The slowness and method of this absorption renders the use of a ligature useless and unsafe. The treatment for dog bite is therefore as follows: _Immediate._ Send for a physician, telling him the reason. While waiting, treat as any similar wound from any cause. If the skin is not penetrated, but scratched only, apply iodine and a sterile or wet dressing. If the skin is penetrated, the treatment should be the same as for a wound made by a dirty nail: that is, a small stick, such as a match, whittled to a point, with a little cotton twisted on the point, should be dipped into tincture of iodine, and twisted down into the full depth of the wound, and then done a second time. _Subsequent._ A physician should be consulted immediately, and if there is any suspicion of the dog being sick it should be kept under observation. The body of a dog that has been killed under suspicion of rabies or hydrophobia, should be sent as soon as possible to the proper authorities. One of the greatest discoveries in medical science is the Pasteur treatment for the prevention of hydrophobia after mad dog bite, and fortunately, provision for this treatment is so widespread that practically every one in civilized regions needing it, can have it, as is well known to all physicians. The fact that the period of development of the disease is so long makes the possibility of prevention greater.
