Wound care is based on three elements that make up what is known as the “VIP” approach. These three elements play an important role in healing a persistent wound. For example, even a small sore on a foot with poor blood circulation can become a serious problem if it is not treated quickly.
In addition to VIP treatments, the wound requires special care to help it heal.
The VIP approach to treatment:
When a wound develops on a diabetic foot, it is important to make sure that there is sufficient blood supply to the foot. If this is not the case, there are ways to improve blood flow, including:
In some cases, it is necessary to perform both procedures. The goal is to restore blood supply to the foot so that oxygen and nutrients can reach the wound, allowing it to heal and reducing the risk of amputation.
People suffering from diabetes often have had hyperglycemia for a long time. When the level of sugar in your blood is high over a lengthy period, your immune system becomes weaker and less effective at fighting infection.
Initially, the signs may not be very noticeable, even if the infection is severe. Watch for changes in temperature, heat, redness, discharge or pain, as mentioned in the section on Complications.
We encourage you to inspect your feet daily and to see a health care professional promptly if you notice any changes. The main challenge for the health care team will be to determine which microbe(s), also known as germs or bacteria, are responsible for your infection, so they can prescribe the right antibiotic.
If the medication is in tablet form, you will take it orally (by mouth). If not, it will be given through a device that delivers it directly to your veins. A course of antibiotics lasts about seven to 14 days. It may be necessary to extend the treatment for several weeks if the bones are affected or if there is a risk of amputation.
Many of the treatments used to promote wound healing require your cooperation. This is the case with “offloading,” which in medical terms refers to the different methods of removing all forms of pressure on the foot.
For the wound to heal, pressure on the foot must be reduced at all times, including pressure created by your body weight. “At all times” means 24 hours a day, seven days a week, and not a minute less. If your health professional prescribes a wound offloading treatment, you must stick to it at all times. The importance of this cannot be overstated.
In fact, the offloading treatment you are prescribed to heal a diabetic plantar ulcer is the same type of treatment that would be recommended if you had suffered a foot fracture and were instructed to keep weight off the affected foot. Would you walk around on a fractured foot without wearing a cast? Obviously not. It is exactly the same for offloading a diabetic foot.
There are several types of devices and techniques associated with offloading. Some of them can be removed, while others cannot.
If you have a diabetic foot wound or ulcer, you should receive what is called “wound care.” This involves cleaning the wound, debriding it if necessary and applying a dressing. This care is provided by health professionals. Sometimes specialized dressings or other advanced wound care techniques will be used. It is important that you follow the recommendations made by the health professional to maximize your chances of recovery.
The process of debriding a wound involves removing the necrotic tissue in and around the wound. This tissue is dead and it promotes infection and prevents the wound from healing. Debridement removes some of the bacteria that cause infection. By “cleaning out” the wound, it helps healthy tissue to heal.
Several methods of debridement are used, including dressings, drugs and scalpels or blades. Debridement should be combined with offloading to take pressure off the wound. This treatment is not painful.
