Apr 20, 2012 · Diabetic neuropathy is the common factor in almost 90% of diabetic foot ulcers [ 9, 10 ]. Nerve damage in diabetes affects the motor, sensory, and autonomic fibers. Motor neuropathy causes muscle weakness, atrophy, and paresis. Sensory neuropathy leads to loss of the protective sensation of pain, pressure, and heat.
What is the best treatment for a wound ulcer?
One important thing to remember is that Grade 1 pressure ulcers do not turn white when pressure is placed on them. The skin remains intact, but it may hurt or itch. It may also feel either warm and spongy or hard. The characteristics are: Non-blanchable erythema of intact skin can be difficult to assess in patients with darkly pigmented skin.

How long does it take for a foot ulcer to heal?
The majority (60–80%) of foot ulcers will heal, while 10–15% of them will remain active, and 5–24% of them will finally lead to limb amputation within a period of 6–18 months after the first evaluation.
What causes muscle weakness and atrophy?
Motor neuropathy causes muscle weakness, atrophy, and paresis. Sensory neuropathy leads to loss of the protective sensation of pain, pressure, and heat. Autonomic dysfunction causes vasodilation and decreased sweating [11], resulting in a loss of skin integrity, providing a site vulnerable to microbial infection [12].
Can diabetic neuropathy cause ulcers in feet?
In patients with peripheral diabetic neuropathy, loss of sensation in the feet leads to repetitive minor injuries from internal (calluses, nails, foot deformities) or external causes (shoes, burns, foreign bodies) that are undetected at the time and may consequently lead to foot ulceration.
What is the first option for surgical treatment of a superficial ulcer?
When the ulcer is superficial and vital tissues such as bone, vessels, nerves or tendons are not exposed, and the ulcer is not copiously discharging, skin grafting is the first option for surgical treatment. The slimy layer over the surface of ulcer is sharply debrided to get a healthy vascular bed for skin grafting.

Can friction cause pressure ulcers?
Friction, along with pressure and shear, is also frequently cited as a cause of pressure ulcers.[14] . Friction can cause pressure ulcers both indirectly and directly. In the indirect sense, friction is necessary to generate the shearing forces.
What does a grade 2 pressure ulcer look like?
Grade 2. In Grade 2 pressure ulcers, some of the outer surface of the skin (the epidermis) or the deeper layer of skin (the dermis) is damaged, leading to skin loss [Figure 1b]. The ulcer looks like an open wound or a blister.

The usual pH of gastric juice is approximately. 2.
How many stages are there in pressure ulcers?
Pressure ulcers are classified by stages as defined by the National Pressure Ulcer Advisory Panel (NPUAP). Originally there were four stages (I-IV) but in February 2007 these stages were revised and two more categories were added, deep tissue injury and unstageable. Pressure Ulcer Staging.
What is pressure ulcer?
Previously called decubitus or bed sore, a pressure ulcer is the result of damage caused by pressure over time causing an ischemia of underlying structures. Bony prominences are the most common sites and causes. There are many risk factors that contribute to the development of pressure ulcers.
What is a wound assessment?
Wound Assessment. An assessment of the wound should be done weekly and be used to drive treatment decisions. Wound assessment includes: location, class/stage, size, base tissues, exudates, odor, edge/perimeter, pain and an evaluation for infection. Location.
What is a slough in a wound?
Often include undermining and tunneling. Unstageable - Full thickness tissue loss in which the base of the ulcer is covered by slough (yellow, tan, gray, green or brown) and/or eschar (tan, brown or black) in the wound bed.
What is a slough?
Slough - Soft, moist avascular tissue that adheres to the wound bed in strings or thick clumps; may be white, yellow, tan or green. Granulation - Pink/red moist tissue comprised of new blood vessels, collagen fibers and fibroblasts. Typically the surface is shiny and moist with a granular appearance.
How do pressure ulcers heal?
The healing process varies depending on the stage of the pressure ulcer. Stage I & II pressure ulcers and partial thickness wounds heal by tissue regeneration. Stage III & IV pressure ulcers and full thickness wounds heal by scar formation and contraction.
What is the difference between shear and friction?
Friction and shear need to be reduced. Friction is the mechanical force exerted when skin is dragged against a coarse surface while shear is the mechanical force caused by the interplay of gravity and friction.
What is the most common site for pressure ulcers?
The most common sites for pressure ulcers are the sacrum, heels, ischial tuberosities, greater trochanters, and lateral malleoli.
What is the assessment of pressure ulcers?
Assessment of an established pressure ulcer involves a complete medical evaluation of the patient. A comprehensive history includes the onset and duration of ulcers, previous wound care, risk factors, and a list of health problems and medications. Other factors such as psychological health, behavioral and cognitive status, social and financial resources, and access to caregivers are critical in the initial assessment and may influence treatment plans. The presence of a pressure ulcer may indicate that the patient does not have access to adequate services or support. The patient may need more intensive support services, or care-givers may need more training, respite, or assistance with lifting and turning the patient. Patients with communication or sensory disorders are particularly vulnerable to pressure ulcers because they may not feel discomfort or may express discomfort in atypical ways.
What is pressure ulcer?
A pressure ulcer is a localized injury to the skin or underlying tissue, usually over a bony prominence, as a result of unrelieved pressure. Predisposing factors are classified as intrinsic (e.g., limited mobility, poor nutrition, comorbidities, aging skin) or extrinsic (e.g., pressure, friction, shear, moisture).
How long does it take for a wound to heal after debridement?
Bacterial load can be managed with cleansing. Topical antibiotics should be considered if there is no improvement in healing after 14 days.

Other considerations in prescribing an antibiotic include the patient’s length of hospital stay, the availability of home health services and infusion services, the influence of the pharmacy and therapeutics committee, the hospital’s formulary, and the influence of the payer’s approval of prescription benefits.
What are the principles of wound care?
General principles of wound assessment and treatment are as follows: 1 Wound care may be broadly divided into nonoperative and operative methods 2 For stage 1 and 2 pressure injuries, wound care is usually conservative (ie, nonoperative) 3 For stage 3 and 4 lesions, surgical intervention (eg, flap reconstruction) may be required, though some of these lesions must be treated conservatively because of coexisting medical problems [ 3] 4 Approximately 70-90% of pressure injuries are superficial and heal by second intention
What is wound debridement?
The purpose of wound débridement is to remove all materials that promote infection, delay granulation, and impede healing, including necrotic tissue , eschar , and slough (ie, the stringy yellow, green, or gray nonviable debris in an ulcer).
What is sodium hypochlorite used for?
Sodium hypochlorite (2.5%) has some germicidal activity but is primarily used to debride necrotic tissue. Before it is used, zinc oxide should be placed around the edges of the wound to reduce the amount of irritation. [ 76] . After cleansing with sodium hypochlorite, normal saline should be used as a rinse. [ 129] .
What is hydrocolloid gel?
This gel can have fibrillolytic properties that enhance wound healing, protect against secondary infection, and insulate the wound from contaminants. [ 57, 130] Hydrocolloids help prevent friction and shear and may be used in stage 1, 2, 3, and some stage 4 pressure injuries with minimal exudate and no necrotic tissue.
What are myocutaneous flaps?
Myocutaneous flaps can help heal osteomyelitis and limit the damage caused by shearing, friction, and pressure. [ 159, 160, 161] They bring muscle and skin to the area of the defect and are probably as resistant to future pressure injuries as the original skin. Free flaps.
