The science of wound care has advanced significantly over the past ten years. We know that wounds and ulcers heal faster, with a lower risk of infection, if they are kept covered and moist.

The use of full-strength betadine, peroxide, whirlpools and soaking are not recommended, as this could lead to further complications. Appropriate wound management includes the use of dressings and topically-applied medications.

These range from normal saline to advanced products, such as growth factors, ulcer dressings, and skin substitutes that have been shown to be highly effective in healing foot ulcers.

For a wound to heal there must be adequate circulation to the ulcerated area. Your podiatrist may order evaluation test such as noninvasive studies and or consult a vascular surgeon. Tightly controlling blood glucose is of the utmost importance during the treatment of a diabetic foot ulcer.

Working closely with a medical doctor or endocrinologist to accomplish this will enhance healing and reduce the risk of complications. A majority of noninfected foot ulcers are treated without surgery; however, when this fails, surgical management may be appropriate.

Healing time depends on a variety of factors, such as wound size and location, pressure on the wound from walking or standing, swelling, circulation, blood glucose levels, wound care, and what is being applied to the wound.

Healing may occur within weeks or require several months. The best way to treat a diabetic foot ulcer is to prevent its development in the first place. Recommended guidelines include seeing a podiatrist on a regular basis. He or she can determine if you are at high risk for developing a foot ulcer and implement strategies for prevention.

Reducing additional risk factors, such as smoking, drinking alcohol, high cholesterol, and elevated blood glucose are important in the prevention and treatment of a diabetic foot ulcer. Wearing the appropriate shoes and socks will go a long way in reducing risks.

Your podiatric physician can provide guidance in selecting the proper shoes. Need for parenteral antibiotics, concern for noncompliance, inability to care for the wound, ability to offload pressure, are few points to be considered for hospitalization.

The common organisms seen in a diabetic foot ulcer are Staphylococcus aureus, Streptococcus, Pseudomonas aeruginosa, and rarely E. Diabetes patients have higher carriage rate of Staphylococcus aureus in the nares and skin, and this increases the chances of infection of the ulcer.

The severity of the infection dictates the dose, duration, and the type of antibiotic. The typical outpatient antibiotics regimen includes oral cephalosporins, and amoxicillin-clavulanic acid combination, If MRSA is not of concern.

If MRSA is suspected, then the oral regimens include linezolid, clindamycin or cephalexin plus doxycycline or a trimethoprim-sulphamethoxazole combination. Parenteral antibiotic regimens include piperacillin-tazobactam, ampicillin-sulbactam, and if penicillin-allergic, then carbapenems including ertapenem or meropenem.

The other combinations regimen including adding metronidazole for anaerobic coverage along with quinolones like ciprofloxacin or levofloxacin, or with cephalosporins like ceftriaxone, cefepime or ceftazidime. Intravenous agents which cover MRSA include vancomycin, linezolid or daptomycin.

The next therapeutic step is to treat any underlying peripheral vascular disease. Inadequate blood supply limits the oxygen supply and the delivery of the antibiotics to the ulcer; hence revascularization improves both, and there is a better chance for the healing of the ulcer.

The subsequent step is to perform local debridement or removal of calluses. Vacuum assisted closure can be undertaken for clean non healing wounds. Others may benefit from hydrotherapy to get rid of infected debris. If the patient has charcot foot, then the initial treatment is immobilization with braces or specially made shoes, but most will require a surgical procedure like arthrodesis or an osteotomy.

Finally, efforts should be made for the prevention of new ulcers or worsening of the existing ulcer, which occurs by offloading the pressure from the site by using walkers or therapeutic shoes. Since the wound has low oxygen supply, there is often delay in healing of the wound. Hyperbaric oxygen therapy improves the rate of wound healing and also reduces the rate of complications.

To have the best outcome a team of health care providers including primary care physician, podiatrist, a vascular surgeon, an infectious disease specialist and wound care nursing staff are imperative.

After the diagnosis of the ulcer, it should undergo staging. One of the commonly used classifications is by Wagner from It classifies wounds into six grades based on the depth [12]. This classification, though, has been criticized as grading merely the depth of the ulceration and not incorporating other factors known to influence the outcome.

Among others, one of the most commonly used classification today is The University of Texas Classification, which not only includes assessment of the depth, but also the type of infection, and ischemia based on the eventual outcome of the wound.

The prognosis these ulcers is good if identified early and optimal treatment initiated. Unfortunately, delays in care can have detrimental effects which can lead even to amputation of the foot.

Patients who have chronic diabetic ulcer have a high risk of rehospitalization and prolonged hospitalization. The most feared complication is amputation of the extremity. The other complications include gangrene of the foot, osteomyelitis, permanent deformity, and risk of sepsis.

Patients who end up with amputation will need comprehensive therapy including physical therapy, occupational therapy and also will need a prosthesis. The most important preventative measure is patient education. If the patient should be made aware about the importance of good glycemic control, proper care of the foot, avoiding tobacco and the need for frequent follow-up examinations, then the risk for developing ulcer is significantly reduced.

The patient should be reminded of these things during each visit with the primary care physician. Diabetes is a chronic disease that has a significant number of life-threatening complications, of which one of them is a foot ulcer. Diabetic foot is a common scenario in which healthcare workers will come across in daily practice.

Besides a lack of blood flow, many patients with diabetes mellitus with a foot ulcer also have neuropathy for which there is no cure. The diagnosis and subsequent management of a diabetic ulcer are optimally effective when utilizing an interprofessional approach to achieve the best outcome.

Many patients with diabetes mellitus with a foot ulcer end up with amputations and become disabled. Thus, today the key is preventing the foot ulcer with education. The pharmacist, nurse practitioner, the primary care provider should educate the patient on the harms of smoking and the need for better control of blood glucose.

In addition, patients with diabetes mellitus need to be taught about appropriate shoe wear, podiatric care, and control of hyperlipidemia. The team, including the diabetic nurse educator and clinicians, must work together toward educating the patient and family on preventative measures to minimize morbidity and improve outcomes.

The social worker should be involved in the care to ensure that the patient with diabetes mellitus has support systems and finances so that care is not jeopardized.

The dietitian should educate the patient on a healthy diet and the importance of maintaining a healthy weight. At every clinic visit, the feet must be examined for skin integrity, pulses and sensation. Appropriate referrals must be made if there are any deficiencies in the foot exam.

Patients with diabetes mellitus should be told that anytime they have an open wound, they should seek immediate care and avoid homemade remedies. Only through an interprofessional approach with open communication can the morbidity of diabetic foot be reduced.

Loss of a limb leads to enormous morbidity and many patients are not able to afford a prosthesis. Most remain disabled for life and lead a poor quality of life. Diabetic Foot Ulcer Neuropathic ulceration in a patient with diabetes Note periwound callous formation.

Copy edited by Gus Mitchell. January Risk factors for developing a diabetic foot ulcer include:. High blood sugar levels can damage the sensory nerves resulting in a peripheral neuropathy , with altered or complete loss of sensation and an inability to feel pain.

This can result in poor wound healing. A diabetic foot ulcer is a skin sore with full thickness skin loss often preceded by a haemorrhagic subepidermal blister.

The ulcer typically develops within a callosity on a pressure site, with a circular punched out appearance. It is often painless, leading to a delay in presentation to a health professional.

Tissue around the ulcer may become black, and gangrene may develop. Pedal pulses may be absent and reduced sensation can be demonstrated. Diabetic foot ulcer Foot ulcer at a pressure site. The severity of a diabetic foot ulcer can be graded and staged. There are many different classification systems.

The University of Texas UT classification is a widely used, validated system Table 1. Grading foot ulcer UT Grade 1. Diabetic foot ulcer is a clinical diagnosis of a painless foot ulcer in a patient with a long history of poorly controlled diabetes mellitus.
