basic human needs alterations in skin integrity pressure ulcers skin integrity skin integumentary system is the body’s largest organ ۱ ۶th of tbw protects against disease causing organisms sensory organ for temp pain touch synthesizes vitamin d injury to skin poses a risk to safety and triggers a complex healing process normal integument ۲ principle layers in relation to wound healing epidermis dermis separated by basement membrane epidermis outer layer has several layers within it stratum corneum stratum lucidem stratum granulosum stratum spinosum basal cell layer dermis inner layer of skin provides tensile strength mechanical support protection to underlying muscle bones and organs contains mostly connective tissue also includes blood vessels nerves sensory nerve cells lymphatics collagen skin functions epidermis functions to re surface wounds restore the barrier against bacteria dermis functions to restore structural integrity collagen physical properties of skin alarming facts pressure ulcers were the primary diagnosis in about ۴۵ ۵ hospital admissions ۲ ۶ among hospital admissions listing pressure ulcers as a primary diagnosis ۱ in ۲۵ admissions ended in death. pressure ulcer related hospitalizations are longer and more expensive than other hospitalizations. avg ۵ day hospitalization ۱ average pressure ulcer related stay extends to ۱۴ days and costs up to ۲ . source ahrq www.ahrq.gov pressure ulcers new npuap terminology ۲ ۷ www.npuap.org a pressure ulcer is a localized injury to the skin and or underlying tissue usually over a bony prominence as a result of pressure or pressure in combination with shear and or friction. a number of contributing factors are also associated with pressure ulcers pressure ulcers tissues receive oxygen and nutrients and eliminates metabolic wastes via the blood any factor that interferes with this affects cellular metabolism and cell life pressure affects cellular metabolism by decreasing or stopping tissue circulation resulting in tissue ischemia causes of pressure ulcers pressure ischemia edema inflammation small vessel thrombosis cell death shear – trauma caused by tissue layers sliding across each other results in disruption or angulation of blood vessels pressure ulcer contributing factors friction shear poor nutrition incontinence moisture co existing medical conditions pressure tissue damage occurs when pressure exerted on the capillaries is high enough to close the capillaries capillary closing pressure is the pressure needed to close the capillary ۳۲ mmhg after a period of ischemia light toned skin undergoes ۲ hyperemic changes hyperemia normal reactive hyperemia visible effect of localized vasodilatation redness area will blanch with fingertip pressure and redness lasts less than ۱ hour abnormal reactive hyperemia excessive vasodilatation and induration edema in response to pressure. skin appears bright pink red. lasts ۱ hour to ۲ weeks risk factors for pressure ulcer development impaired sensory input impaired motor function altered level of consciousness orthopedic devices pathogenesis of pressure ulcers intensity of pressure and capillary closing pressure duration and sustenance of pressure tissue tolerance pathogenesis of pressure ulcers bony prominences are most at risk sacrum heels elbows lateral malleoli greater trochanter ischial tuberosities pressure ulcer forms as a result of time pressure relationship greater the pressure and duration of pressure the greater the incidence of ulcer formation pathogenesis of pressure ulcers skin and subcutaneous tissue can withstand some pressure tissue will over time become hypoxic and ischemic injury will occur if the pressure is above ۳۲mmhg and remains unrelieved to the point of tissue hypoxia the vessel will collapse and thrombose pathogenesis of pressure ulcers if circulation is restored before this critical point circulation to tissue is restored reactive hyperemia skin has a greater ability to tolerate ischemia than does muscle hence true pressure ulcers begin at bone with pressure related to muscle ischemia eventually coming through to epidermis shear injury sacrum and heels most susceptible pressure ulcer staging depth of destroyed tissue does not indicate healing ulcer covered by necrotic tissue or eschar cannot be staged until debrided npuap system used most clinically other staging systems exist stage ۱ pressure ulcer intact skin with non blanchable redness of a localized area usually over a bony prominence. darkly pigmented skin may not have blanching its color may differ from the surrounding area the area may be painful firm soft warmer or cooler as compared to adjacent tissue. stage i may be difficult to detect in individuals with darker skin tones stage i treatment off load pressure transparent film dressing hydrocolloid dressing moisture barrier stage ii stage ۲ pressure ulcer partial thickness skin loss involving the epidermis and or dermis. the ulcer is superficial and presents clinically as an abrasion blister or shallow open ulcer presents as shiny or shallow ulcer red pink wound bed without slough or bruising. this stage should not be used to describe skin tears tape burns perineal dermatitis maceration or excoriation stage ii treatment hydrocolloid dressing dressing of choice in minimally draining stage ii ulcer absorptive dressings foam draining wounds hydrogel healing wounds off load pressure stage iii stage iii full thickness skin loss involving damage or necrosis to subcutaneous tissue that may extend down to but not through underlying fascia ulcer presents as a deep crater with or without undermining or tunneling of adjacent tissue slough tissue may be present but does not obscure the depth of tissue loss depth varies by anatomical location stage iii treatment requires physician order for stage iii or iv draining vs. non draining necrotic vs. granulating draining wounds absorptive dressings granulating wounds hydrogel necrotic wounds require debridement chemical. mechanical autolytic sharp stage iv stage iv full thickness skin loss with extensive destruction tissue necrosis or damage to muscle bone or supporting structures tendons joint undermining and tunneling are often associated with stage iv ulcers slough or eschar may be present in some on some parts of the wound bed depth of wound varies by anatomical location exposed bone or tendon is visible or directly palpable unstagable wounds 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 black in the wound bed the true depth of the wound cannot be determined until slough or eschar is removed therefore stage cannot be determined. stable eschars serve as the body’s natural biological cover and should not be removed unstageable deep tissue injury purple or maroon localized area of discolored …
