It is far better not to interfere if you do not know what to do than to do harm. One should offer no advice if they are not qualified to give advice. Much harm has resulted from doing the wrong thing in these cases. The instruction in the following pages is given so that the average mother may know what to do in emergency but not with the intention that she may regard her knowledge as sufficient to dispense with the aid of the physician. Arrest of Hemorrhage.--When there is a wound there is always bleeding; this means that some blood vessels have been cut or torn open allowing blood to escape. The character of the hemorrhage will determine the nature of the treatment to be employed. On general principles, the first thing to do in the presence of bleeding is to elevate the part, if that is possible. If there is simply a general oozing of blood, it may be controlled and arrested by pressure. This pressure should be steady and prolonged. It is best accomplished by wetting a clean handkerchief or a pad of gauze in ice cold water, placing this on the part and binding it on firmly with a bandage. If the discharge of blood flows in a steady stream and is rather dark the hemorrhage is coming from a vein. We know that veins carry blood toward the heart so that any pressure or constriction employed to stop a venous hemorrhage should be tied on the side of the wound further removed from the heart. Inasmuch as veins have soft walls the right kind of pressure will in most instances stop the bleeding. The part should be elevated after the pad is adjusted in place. Any tight band on the limb as a garter or sleeve band should be removed as they tend to interrupt the return circulation.
