Wound Classification • Wound Age • Wound Depth • Wound Color
Wound ClassificationWound Age • New or relatively new wound • Occurs suddenly • Healing progresses in a timely, predictable manner • Typically heals by primary intention • Examples: surgical and traumatic wounds • May develop over time • Healing has slowed or stopped • Typically heals by secondary intention • Examples: pressure, vascular and diabetic ulcers Acute Chronic
Wound ClassificationWound Depth • Partial thickness wound • Involves only epidermis or epidermis and part of the dermis • Does not extend through the dermis • Full thickness wound • Extends through the dermis into tissues beneath • May expose adipose tissue, muscle or bone
Wound ClassificationWound Color • Red-Yellow-Black Classification System • Red wounds: indicate normal healing • Red because of granulation tissue • Yellow wounds: fibrin left from healing process appears as yellow slough or dead tissue on wound base • Slough, or soft necrotic tissue, serves as a medium for bacteria growth • Black wounds: indicates necrosis • Eschar • Cannot accurately assess a wound covered in eschar
Wound Color • Classifying multicolor wounds: • classify according to the least healthy color
Wound Terminology • Abrasion: occurs from a scraping away of the surface layers of skin, often result of trauma • Contusion: skin is not broken; characterized by pain, swelling and discoloration (bruise) • Hematoma: swelling or mass of blood, usually caused by a break in a blood vessel • Laceration: wound or irregular tear of tissues often assoc. with trauma (cut)
Wound Terminology • Penetrating wound: wound that enters into the interior of an organ or cavity • Puncture: a wound made by a sharp pointed instrument or objet by penetrating through the skin into underlying tissues
Wound Terminology • Granulation: beefy red, bumpy, shiny tissue in the base of an ulcer • Epithelial tissue: pale or dark pink skin, first appears at wound borders • Slough: soft, yellow necrotic tissue • Eschar: thick, hard, leathery black tissue; indicates dry, necrotic tissue • Macerated tissue: indicates too much water, white at edges
Wound Terminology Drainage (Exudate) Descriptions • Serous: clear, light color with thin, watery consistency • Sanguineous: red with thin, watery consistency; indicates new vessel growth or disruption of blood vessels • Serosanguineous: light red or pink with thin, watery consistency; can be seen in healthy wound • Purulent: creamy yellow, green, white or tan; thick and opaque
Types of ulcers • Pressure ulcers • Vascular ulcers • Arterial ulcers • Venous ulcers • Lymphatic ulcers • Neuropathic ulcers • Diabetic ulcers • Malignant wounds
Pressure ulcers Causes • Occur when pressure compresses soft tissue over bony prominences • Friction and shear contribute to development of pressure ulcers
Pressure Ulcer Risk Factors • Advanced Age • Immobile • Incontinence • Infection • Low blood pressure • Malnutrition
Pressure Ulcers Prevention • Pressure relief • Positioning, air mattress • Reduce friction and shear • Maximize nutritional status • Control chronic illness (such as diabetes) • Manage moisture associated with incontinence
Pressure Ulcers Assessment • Length X width • Measure the greatest length (head to toe) and the greatest width (side to side). Always use a cm ruler • Exudate amount • Estimate the draining present after removing dressing and before applying any ointment • Classify as none, light, moderate or heavy Assessment cont. • Tissue type • Type of tissue in wound bed • Describe as necrotic, slough, granulation, epithelial, or closed
Pressure Ulcers Assessment cont. Staging: National Pressure Ulcer Advisory Panel (NPAUP) • Stage I: intact skin, but color differs from surrounding area; changes in skin temperature, tissue consistency and sensation • Stage II: partial thickness loss of epidermis and/or dermis; shallow, open; may also present as a blister or abrasion
Pressure Ulcers Staging cont. • Stage III: Full thickness tissue loss; subcutaneous fat may be visible; deep crater, with or without undermining or tunneling into adjacent tissue • Stage IV: full thickness tissue loss with exposed bone, tendon, or muscle; undermining and tunneling are common
Pressure Ulcers Treatment • Patient education • Pressure relief • Manage moisture • Nutritional assessment and support • Proper wound care
Vascular Ulcers Venous Ulcers – Causes and S&S • Wounds result from venous insufficiency • Incompentent valves • Inadequate calf muscle function • Pitting edema is common • Pt c/o itching, fatigue, aching, and heaviness in involved limbs
Vascular Ulcers Venous Ulcers – Continued Eczema is commons in patients with recurrent ulcers Skin changes including hemosiderosis (inc localized iron stores) and lipodermatosclerosis (extemely smooth skin that turns brown and becomes tight and painful from inflammation of fatty tissue)
Vascular Ulcers Venous Ulcers – Assessment • Must determine if patient also has arterial insufficiency • Measure and monitor edema • Classify as partial thickness or full thickness wound
Vascular Ulcers Arterial Ulcers – Causes • Result from tissue ischemia caused by insufficient blood flow to an area • Causes • Arterial stenosis • Obstruction (from thrombosis, emboli, atherosclerosis, vasculitis or Raynaud’s phenomenon
Vascular Ulcers Arterial Ulcers – S&S • Dependent rubor • Pain in legs and feet • Pale, shiny skin • Faint or absent pulses • Ulcers on dorsum of foot, distal toes, lateral malleolus
Vascular Ulcers Arterial Ulcers – Assessment • Ankle Brachial Index (ABI) • A test to examine the vascular system. A normal resting ankle-brachial index is 1.0 to 1.4. This means that your blood pressure at your ankle is the same or greater than the pressure at your arm, and suggests that you do not have significant narrowing or blockage of blood flow. Abnormal is .9 or less
Vascular Ulcers Arterial Ulcers – Assessment Medical diagnostic tests are often necessary to determine if there is adequate blood flow to the LE to support healing
Vascular Ulcers Lymphatic Ulcers – Causes and S&S • Result from injury to a body part afflicted with lymphedema • Pressure on capillaries • Skin folds from massive swelling • Traumatic injury or pressure • Ulcers are typically shallow with large amounts of moisture • No pitting edema • Lots of swelling • Thickened skin
Vascular Ulcers Lymphatic Ulcers – Assessment • Patient history of damage or injury to lymphatic system • Inspection • Palpation • Girth measurements • No special tests are usually needed
Neuropathic Ulcers Causes • diabetes is most common cause S & S • Located on weightbearing surfaces of the foot • Could have sensory, motor and/or autonomic neuropathy • Calluses • Induration is common • Erythema • Skin fissures • Dry, scaly skin • Pedal pulses diminished or absent • Usually good granulation with little to no drainage
Neuropathic Ulcers Prevention • Control diabetes • Patient education in regards to maintaining careful glycemic control • Foot hygiene • Inspect feet daily for injury or pressure areas • Wash feed with mild soap, dry between toes • Don’t go barefoot • Take extreme caution with cutting toenails, best to see a podiatrist
Neuropathic Ulcers Prevention cont. • Choosing socks • Wear natural fiber socks • Choose socks that take perspiration away from skin • Use diabetic socks for shear and friction control • Choosing shoes • Wear shoes that fit well • Break in new shoes • Inspect shoes prior to putting on
Neuropathic Ulcers Assessment • Semmes-Weinstein test • Uses monofilaments to check protective sensation in feet • Wagner Ulcer Grade classification • Used to evaluate diabetic ulcers • Low scores represent less complex ulcers
Neuropathic Ulcers Treatment • Relieve pressure on area of wound • Surgical referral for bony deformities • Callus debridement • Appropriate wound care • Use of growth factors as ordered
Malignant Wounds Causes • Develop from primary or metastatic tumor that infiltrates the epidermis • Commonly occur in patients with breast cancer • Also in patients with untreated skin cancer
Malignant Wounds Characteristics • Grow rapidly • Often invade surrounding tissues/organs • Sinus tracts and fistulas are common • Cauliflower like appearance • Fragile blood vessels • Large amounts of necrotic tissue
Malignant Wounds Complications • Odor • Bleeding • Exudate • Pruritus (itching) • Pain
Malignant Wounds Treatment • Control exudate and bleeding • Use dressings to minimize odor • Pain management
