Wound Care Can Make All The Difference

WHEN INSPECTING JOHN´S feet in my office one afternoon, I noticed what appeared to be the head of a Phillips-head metal screw on the surface of his heel. John, an overweight diabetic, had walked in smiling, wearing slippers.
The 1-inch screw imbedded in his heel - that John couldn´t feel because his diabetes had caused his feet to be numb - became so infected that eventually John needed amputation of his foot.
John´s wound improved when he was in the hospital, but always worsened when he went home. Despite many educational sessions, John didn´t believe that he could help his wound heal.
Most of us recall being cut as children, and observing that wounds seemed to heal almost no matter what we did. But as we age or become chronically ill, getting wounds to heal often requires more effort.
The secrets to good wound healing are:
Blood flow to the wound can be maximized by a number of actions.
The simplest way to decrease tissue swelling around the wound is to elevate the wound. If the wound is on the foot or leg, the patients should lie down and elevate the wound well above the level of the heart. If the wound is on the buttock, the person should lie face down.
The most common mistake I've seen patients make is to sit with the wounded foot on a stool or ottoman. That position often kinks the blood vessels in the hip, reducing blood flow and increasing swelling, and doesn't elevate the wound enough.
The patient must lie down - almost flat, and elevate the leg so he or she is looking up at the wound.
Generally, elevation should be done for another 15-30 minutes three-to-four times a day, right after the application of moist warmth, or while applying the heat.
So, for leg or foot wounds, maximize lying down (with wound elevation) and walking (with limitations), and minimize sitting and standing because these worsen swelling.
The second part of wound care is to minimize infection.
Put simply, gently wash the wound with soap and water, apply an antibiotic ointment, and cover the wound to keep out germs, usually twice a day, unless your doctor instructs you differently.
If the wound does not improve, or if you have diabetes or a history of poor wound healing, consult your doctor or a wound care specialist.
