First Aid Rule 1.—Neutralize the alkali. Pour vinegar over the burn.
Rule 2.—Control pain. Wash off vinegar with stream of water. Dry gently. Apply vaseline or cold cream.
BURNS CAUSED BY STRONG MINERAL ACIDS OR BY ALKALIES.—If acids are the cause, the skin should not be washed at first, but either chalk, whiting, or some mild alkali, as baking soda, should be strewn over the burn, and then after the effect of the acid is neutralized, wash off the soda with stream of warm water. Dry gently with gauze. Apply Carron oil or paste of boric acid and vaseline, equal parts. If strong alkalies have been spilled on the skin, as ammonia, potash, or quicklime, then vinegar is the proper substance to employ, followed by washing. Then dry gently. Vaseline or cold cream is usually sufficient as after treatment. Limewater is useful in counteracting the effect of acids spattered in the eye. In the case of alkalies in the eye, the vinegar used should be diluted with three parts of water. Albolene or liquid vaseline is the best agent to drop in the eye after either accident, in order to relieve the irritation and pain, and the patient should stay in a dark room.
FROSTBITE, REAL FREEZING.—Nose, ears, fingers, toes; insensible to touch, stiff, pale or blue. Person may be unconscious.
First Aid Rule 1.—Restore circulation. Rub gently, then vigorously, with snow.
Rule 2.—Restore heat very gradually. Sudden heat is fatal. Keep in cold room, and rub with cloth wet with very cold water till circulation is established. Then rub with equal parts of alcohol and water and expose gradually to heat of living room.
Rule 3.—If person ceases to breathe, resuscitate as if drowned. Open his mouth, grasp his tongue, and pull it forward and keep it there. Let another assistant grasp the arms just below the elbows and draw them steadily upward by the sides of the patient's head to the ground, the hands nearly meeting (which enlarges the capacity of the chest and induces inspiration.) (See pp. [30] and [31].) While this is being done, let a third assistant take position astride the patient's hips with his elbows resting on his own knees, his hands extended ready for action. Next, let the assistant standing at the head turn down the patient's arms to the sides of the body, the assistant holding the tongue changing hands if necessary to let the arms pass. Just before the patient's hands reach the ground the man astride the body will grasp the body with his hands, the ball of the thumb resting on either side of the pit of the stomach, the fingers falling into the grooves between the short ribs. Now, using his knees as a pivot, he will at the moment the patient's hands touch the ground throw (not too suddenly) his whole weight forward on his hands, and at the same time squeeze the waist between them, as if he wished to force something in the chest upward out of the mouth; he will deepen the pressure while he slowly counts one, two, three, four (about five seconds), then suddenly lets go with a final push, which will send him back to his first position. This completes expiration. (A child or a delicate person must be more gently handled.)
At the instant of letting go, the man at the head of the patient will again draw the arms steadily upward to the sides of the patient's head as before (the assistant holding the tongue again changing hands to let the arms pass, if necessary), holding them there while he slowly counts one, two, three, four (about five seconds).
Repeat these movements deliberately and perseveringly twelve or fifteen times in every minute—thus imitating the natural motions of breathing. Continue the artificial respiration from one to four hours, or until the patient breathes; and for a while after the appearance of returning life carefully aid the first short gasps until deepened into full breaths.
Keep body warm after this with warm-water bottles.
