In all mild varieties home remedies may suffice, but in the more serious and extensive bruises it is advisable to seek medical assistance. It is essential to completely put the part to rest and to elevate it. This will relieve the pain and favor the absorption of the exuded blood. If the bruise is on the foot, the leg should be elevated until the foot is higher than the hip. If, on the hand, it should be so held that it will be higher than the elbow and it may frequently be held higher than the shoulder to relieve the throbbing and the pain. As a rule, cold should be applied as soon after the injury as possible, cloths wrung out of ice water, or a piece of ice may be bound on the part for a short time. The object of the cold is to stop the internal bleeding. If the injury is slight, as are most of the injuries of the household, the mother may apply repeated cloths wrung out of very hot water. This procedure tends to aid the immediate absorption of the blood and prevents a discoloration of the part. If there is great pain relief may be afforded by applying a firm bandage saturated in the lead-water and laudanum mixture which may be obtained in the drug store under the name of lead and opium wash. The bruised part should be massaged every day and a simple ointment may be applied to soften the inflamed area. If any complication arises in the treatment of a bruise, it will be necessary to consult a physician. Wounds.--A wound implies an injury to the skin in addition to injury to the underlying parts to a lesser or greater extent. The skin may be opened by cutting, or stabbing wounds; or it may be punctured, torn, contused, or bruised open. These injuries are effected in various ways. We speak of machinery or mechanical wounds, or gunshot wounds, bites, cuts, stabs and other varieties of wounds. It is very important to know exactly how a wound is produced and the nature of the instrument which opened the skin. We try to obtain this information in order to estimate the probable degree of poison that may or may not have entered into the wound. The first thing to do in treating wounds is to stop the bleeding. If the patient is suffering from shock he should be given active treatment for this condition as described elsewhere. If the wound contains any foreign bodies these should be removed. The wound should then be cleansed, closed and dressed and kept at rest. If the wound is poisoned, or if there is any fear that lockjaw may arise, or if the wound has been caused by a mad dog it will require special treatment.
