The clotted blood with which a wound may be filled, is nature’s means of arresting the hemorrhage, and it must never be disturbed or washed off, lest this open the blood vessels again and thereby renew the bleeding. The arrest of hemorrhage is accomplished by the application of cold or ice water, by hot water and by pressure upon the arteries. Persons fainting from the loss of blood should always be laid with their heads lower than the body; cold water should be dashed into their faces so as to restore them to consciousness. Moderate hemorrhage from the smallest vessels and from the veins generally ceases from slight pressure over the wounds or by drawing or pressing the edges of the wounds together. In a very short time the blood coagulates and forms a temporary plug until the vessels themselves become permanently sealed by a similar process. The pressure must often be continued for a considerable time until the object has been attained. A folded clean cloth or compress is laid over the wound which is the source of the hemorrhage, and this is retained by means of a properly adjusted bandage. If notwithstanding the pressure exerted by the bandage or with the hands, the scarlet blood saturates the cloth and continues to flow, it indicates that a very large vessel is wounded, and thus life may be seriously threatened and in proportion to the magnitude of the wounded vessel, a surgeon should now be summoned to make a further investigation. Hemorrhage from varicose veins of the legs may be checked by a compress fastened over the site of the wound by a bandage, but every constriction around the waist or above the knee by a garter must be loosened. If the patient’s life is threatened from the bleeding, the limb must be elevated, and the pressure of the compress increased, or the pressure should be exerted on the trunk of the bleeding artery above the wound or injury. (_c_) Burns and scalds are the most commonly fatal injuries which occur in modern life. The extended use of steam machinery, the universal employment of coal oil, the general use of the phosphorus and sulphur matches, and the flowing manner of woman’s dress has materially increased the liability of this accident. Of all accidents, burns involve the victim in the most agonizing pain and protracted suffering. Burns are liable to serious complications; the obstinacy to the healing of vast ulcerated surfaces, or the lifelong mutilation to which they condemn the unhappy patient, the rapid draft they make on the patient’s strength, and the danger of abscess and ulceration of internal vital organs which eventually destroy life.
