Wоund Cаre The fоllоwing informаtion wаs obtained from the Nursing 2020 journal - https://journals.lww.com/nursing/Fulltext/2019/10000/Wound_Care_101.10.aspx. Successful wound management starts with a thorough assessment of the wound and periwound skin. The assessment should include the following components. Anatomic location. Location can provide information regarding possible causes of the wound. For example, a wound over the sacral area in a bed bound or immobile patient could be a pressure injury, a wound in a lower extremity with accompanying edema could be a venous ulcer, and a wound on the plantar surface of the foot may be a neuropathic ulcer. Degree of tissue damage. Determining the degree of tissue damage in a wound will help to guide the care plan and will provide some information regarding the healing trajectory. Wounds can be described as partial thickness, with damage limited to the epidermal and/or dermal layers, or full thickness with damage evident in the subcutaneous layers and below (see Skin anatomy). For pressure injuries, the staging classification defined by the National Pressure Ulcer Advisory Panel (NPUAP) is used to describe the appearance of the wound and the extent of tissue damage. Type of tissue in the wound. Tissue in the wound bed can be described as viable or nonviable. Viable tissue can appear beefy red as with granulation tissue, or light pink in the case of new epithelial tissue. In contrast, the appearance nonviable or necrotic tissue varies: Eschar may be black, brown, or tan; fibrin slough is described as stringy or adherent and yellow in color. Wound size. Describe the size of a wound according to linear dimensions (length times width). Measure a wound's length using the head-toe axis; measure its width from side to side. If the wound has depth, measure from the deepest point of the wound to the wound surface using a sterile cotton-tip applicator. Assess for sinus tracts (sometimes called tunneling), which can occur in full-thickness wounds. This dead space has the potential for abscess formation. The depth of a sinus tract can be measured by gently probing the area with a sterile cotton-tip applicator. The distance from the visible wound base to the end of the tract indicates the tract's depth. Identify and measure the location of sinus tracts using the analogy of a clock face, with 12:00 pointing toward the patient's head. Undermining is tissue destruction at the edge of the wound, creating a liplike effect. This can also be measured by gently probing the area with a sterile cotton-tip applicator and recording the location using the clock face analogy. Wound edges and periwound skin. The outer edge of the wound can provide information regarding how long a wound has been present and may even assist in determining the etiology. Wounds over bony prominences with defined edges may be related to pressure. Venous wounds found on the leg are characterized by an irregular shape and undefined edges. Infection. Note the presence or absence of signs and symptoms of local infection (erythema, induration, pain, edema, purulent exudate, wound odor) during the wound assessment. Keep in mind that patients with chronic wounds may not exhibit these classic signs and symptoms of infection due to the presence of biofilm. This extracellular polysaccharide matrix embeds microorganisms, delays healing, and renders infection difficult to diagnose. Pain. The presence and intensity of pain associated with the wound can provide some important information regarding wound etiology and wound chronicity. However, the degree of pain may not correlate to the extent of injury. Skin tears, for example, can be very painful because damage confined to superficial skin can expose nerve endings in the dermal layer. Conversely, patients with neuropathic ulcers on the plantar aspect of the foot and concomitant peripheral neuropathy may feel little or no pain, even if the wound is grossly infected. A patient with type 2 diabetes presents with the following wound. How would you classify the wound?
