HEMORRHAGES.
Hemorrhage from the arteries may be recognized by its bright red color and by the spurting jets by which the blood leaves the wound. Venous (from the veins) hemorrhages flow in a steady stream and are darker in color. Arterial hemorrhage may be checked by firm pressure over the side nearest the heart or above the wound. Venous hemorrhages may be checked by firm pressure on the side distant from the heart or below the wound. Large veins like the jugular should be compressed both above and below the wound because the vein may bleed from both ends. If possible, digital pressure should be made directly over the bleeding point.
Hemorrhage from the leg may be checked by firm pressure upon the femoral artery, in the middle of the groin at the top of the thigh.
Hemorrhage from the forearm by compression under the inner edge of the biceps against the humerus.
Hemorrhage from the upper arm by compression of the axillary artery against the humerus in the axilla.
Hemorrhage from the cheek by compression on the facial artery against the lower jaw just in front of the masseter muscle.
Flexing the limbs at the joints with a pad between them to make the compression secure and then binding the part may prove a successful method of arresting the flow of blood. A constrictor of rubber tubing twisted firmly around the limb is a ready appliance and a most successful way of checking a flow of blood from an injured limb. But it should not remain on longer than absolutely necessary or gangrene may result from complete stoppage of the circulation.
Wounds should be packed fully and evenly with some absorbent material. Applications of heat and cold are common methods of checking hemorrhages, heat being at all times preferable. Hot water poured on open wounds will encourage coagulation. Bleeding from an ulcer of the leg, which often results from varicose veins, should be stopped by firm pressure over the wound.
Hemorrhage from the Lungs.—A teaspoonful of salt taken internally may stop it. Place an ice-bag over the chest. Morphin, gr. ⅛-¼, may be given under the instructions of a physician. In all cases put patient in bed and enjoin complete rest until medical aid arrives.
Nose-bleed (Epistaxis).—First of all, position and rest should be attended to. The patient should not lie down unless very weak. The higher the head the better. Loosen clothing about the neck and thorax. Caution patient against coughing or sneezing. Holding the nostril tightly closed, with cold applications to the back of the neck, is sometimes successful. Insufflation of ice- or alum-water, or of tannic acid solution may induce coagulation. Profuse bleeding will require packing of the nostrils.
