In case of collapse following an accident, operation, or fright: treat first as for fainting. Then wrap the person in blankets, apply heat, and rub his limbs toward the body, keeping him well wrapped up the while. If he is conscious, and not bleeding externally or internally, give him hot tea or coffee, or just one good drink of liquor, or ammonia. But if the shock is from an injury and attended by bleeding, the first thing to do is to check the flow of blood.
Lay the man on his back with head somewhat raised. Hot water poured on his head will help to arouse him. Apply heat as for shock, but keep the head cool with cold wet cloths. Rub his limbs. Ammonia may be held under the nose, but do not give any stimulant: that would drive the blood to the brain, where it is not wanted. Keep the patient quiet Light diet and laxatives.
If the heart has stopped, the case is fatal. If not, but breathing is suspended, practice artificial respiration for at least half an hour, and other treatment as for drowning. Electric burns are treated like any other.
Observe the difference between this and heat exhaustion (see below). In sunstroke proper the face is red, the skin very hot and dry, and the subject is quite unconscious. Lay him in a cool place; position same as for stunning. Remove as much of his clothing as practicable. Hold a vessel or hatful of cold water four or five feet above him, and pour a stream first on his head, then on his body, and last on his extremities. Continue until consciousness returns. If this cannot be done, then rub cold cloths over face, neck, chest, and armpits. Hold ammonia under the nose. When the patient becomes conscious, let him drink cold water freely, but no stimulants.
