preventing ARDS with burns
• give positive end-expiratory pressure (PEEP) to augment ↓lung volume by providing a continuous positive pressure in airways & alveoli
The OR layout
• helps prevent infection by ↓ contaminants through air exchanges in room, maintaining recommended temp & humidity levels, & limiting traffic & activities in OR. • Safety straps used for pt, & operating bed locked in place. • Blankets or warming units used to prevent hypothermia, • interventions used to prevent skin breakdown.
homografts or allografts
• human skin obtained from a cadaver & provided through a skin bank • disadvantage: $750-1500 & risk of bloodborne pathogens
turgor
• indicates amt of skin elasticity. • Avoid mistaking dehydration for dry skin in older adult • always assess on forehead or chest, & also assess for other indicators of dehydration.
autografting
• involves taking healthy skin from an area of patient's intact skin & transplanting it to an excised burn wound
burn wound sepsis
• leading cause of death during the acute phase of recovery
synthetic dressings
• made of solid silicone & plastic membranes
Collagen
• main component of dermal tissue • protein formed by fibroblasts. • ↑ in areas of tissue injury & helps form scar tissue
Coughing & splinting
• may be performed along w/ deep breathing q1-2h after surgery. • to expel secretions, keep lungs clear, allow full aeration, & prevent pneumonia & atelectasis. • Splinting incision area provides support, promotes a feeling of security, & reduces pain during coughing.
pain relief with burns
• morphine (monitor resp & constipation) • anesthetic agents such as: • ketamine, pentobarbital sodium & nitrous oxide
Emergency Care of the Patient Experiencing an Opioid Overdose
• naloxone hydrochloride (Narcan) 1-2 mg IV. • Repeat q2-3 min up to 10 mg, depending on pt's response. • Maintain open airway. • Give O2 if hypoxia or resp < 10 • Have suction equipment available - can trigger vomiting • Continuously monitor VS & LOC for reversal of overdose. • Do not leave pt until fully responsive. • Assess for pain- reversal of opioid overdose also reverses analgesic effects. • Continue to monitor VS & LOC q10-15 min for 1st hour. Naloxone is eliminated from body more quickly than opioid, and may induce SE, incl. BP changes, tachycardia, & dysrhythmias. • Determine need for additional antagonist therapy
Assessing GI System
• nausea & vomiting COMMON • At risk: motion sickness, obese, opioid use • Zofran, meclizine • ABD surgery- intestinal peristalsis may be delayed at least 24 hrs • NG tubes: record color, consistency, & amt q8h
NPO
• no eating, drinking (including water), or smoking (nicotine stimulates gastric secretions). • Regardless of type of surgery & anesthesia planned, pt is NPO before surgery to ↓ risk of aspiration. • Failure to adhere= cancellation of surgery or ↑ risk for aspiration during/ after surgery.
Anxiety
• often causes restlessness & sleeplessness. • Pt may perceive surgery as threat to life & function. • Assess pt's level of anxiety. • Interventions such as teaching & communicating w/ pt before surgery, enabling pt to use previously successful coping mechanisms, & giving antianxiety drugs help ↓ anxiety. • Incorporate available support systems into plan of care.
opioid drugs
• only given IV in resuscitation phase because it won't relive pain IM or SQ & an overdose during fluid remobilization is reduced
epidermis
• outermost layer of skin • anchored to dermis by finger-like projections of dermal tissue (dermal papillae) • <1 mm thick, but is protective barrier between body & environment.
Neurologic status
• overall mental status, LOC, orientation, ability to follow commands. • baseline neurologic status • motor or sensory deficits. • patient who has been independent & oriented at home can be disoriented in hospital setting. (Ask Family) • RISK FOR FALLING • mental status, muscle strength, steadiness of gait, sense of independence • Document ability to ambulate & steadiness of gait as baseline data.
auto-contamination
• patients own normal flora overgrows & invades other body areas
Melanocytes
• pigment-producing cells found at basement membrane. •cells give color to skin & account for ethnic differences in skin tone. • Darker skin tones are not caused by ↑ numbers; rather, size of pigment granules (melanin) contained in each cell determines color.
jobst pressure garments
• prevent contractures & tight hypertrophic scars • stop venous stasis and edema • saves mobility • must be worn at least 23 hrs a day everyday until scar tissue is mature (12-24 months)
Preventing Injury Interventions
• prevent injury from positioning during surgery. • anesthesia & narrow OR bed= patient's normal defense mechanisms cannot guard against nerve or joint damage & muscle stretch or strain. • Pressure ulcers start developing during surgery • circulating nurse pads operating bed w/ foam & /or silicone gel pads & properly places grounding pads. • coordinates transfer to operating bed & helps pt to comfy position. • skin is assessed, esp. older patients- bruising/ injury, & extra padding is placed as indicated.

encourage pt to eat
-frequent high protein snacks -vitamin and mineral substances if needed
given in the first 8 hours
-half of the total volume being given -occurs at time of injury (ex: accident at 8am, get to ED at 10am, infuse now over 6hours)
superficial thickness wounds
-have the least damage because the epidermis is the only part of the skin injured -caused by prolonged exposure to low intensity heat or short exposure to high intensity heat (sunburn, flash burns)
urticaria
-hives -red or white edematous papules or plaques of various size -usually caused by exposure to allergens that release histamines in dermal tissue - blood vessel dilation & leakage of plasma proteins form lesions or wheals.
pressure ulcer prevention
-identification of high risk patients -intervetions using pressure relief-reducing devices
emergency management: chemical burns
-if dry chemicals are present on skin or clothing, DO NOT WET THEM -brush off dry chemicals -remove patients clothing -ascertain the type of chemical causing the burn -do not attempt to neutralize the chemical

-immunosuppression caused by reactivation of the dormant chicken pox virus in pts who have previously had chicken pox -minor irritation to severe deep pain -usually lasts several weeks -complications -full thickness necrosis -bells palsy -eye infection (scaring if gets in eye) -vaccine; Zostavax
escharotomy
-incision through burn eschar relieves pressure caused by constricting force of fluid under circumferential burns on extremity or chest & improves circulation -incisions are made along length of extremity & into subcutaneous tissue
cardiac changes from burns
-increased HR -decreased CO until 18-36 hrs after & increase after fluid resusitation
metabolic changes from burns
-increased metabolism so high needs of oxygen and calories -increased core body temperature
Laboratory Assessment
-increased test results common (more concentrated) in 1st 24-48 hrs post-surgery -bandemia = increased WBC differential- indicates infection "left-shift" -ABG tests: for resp or cardiac disease -Urine/kidney tests: urinalysis, creatinine, urine electrolyte levels
cutaneous anthrax

aggravating factors for psoriasis
-infections -hormonal changes -stress -drugs -obesity -presence of other diseases
cellulitis
-inflammation of the skin cells -either staph or strep -involves deeper connective tissue
compensatory response to burns

promote mobility to prevent contractures
-keep patient in neutral body position w/ minimal flexion -ROM at least 3 x a day -ambulation ASAP after fluid shifts have resolved -pressure dressings
subcutaneous tissue/hypodermis
-lies below the dermis and varies in thickness -basement membrane separates this from the dermis -with this burned in deep burns bones, tendons, and muscles may be exposed
psoriasis
-lifelong scaling disorder with underlying dermal inflammation -no cure -cell division is speeded up so cells are shed every 4-5 days (normal is 28 days)
ECG
-ll pts over a certain age (40-45) or hx of heart issues
assess wounds for
-location -size -color -extent of tissue involvement -cell types in wound -exudate -condition of surrounding tissue -presence of foreign bodies
considerations of older adults with fluid resuscitation
-may be a complicating factor w/ cardiac diseases like HF and MI -may use drugs that increase CO or strengthen contraction with fluid (dopamine, digoxin)
partial thickness wounds
-more superficial -damage to the epidermis and upper layers of dermis -immediate local inflammation -heal by re-epithelialization -about 5-7 days -faster if hydrated, oxygenated, few microorganisms
pressure ulcer
-most common in hips, sacrum, and ankles
hypovolemic shock
-most common shock with burns is
steroid therapy
-suppresses inflammation -must taper off use; cant just stop abruptly -CANNOT cure inflammation; just relieves it -NEVER apply to potentially infected skin or face. suppresses local immune response and can worsen infection. makes pt more vulnerable to steroid effects
The surgical team consists of
-surgeon -one or more surgical assistants -anesthesia provider -the OR nursing staff. -Perioperative, or OR nurses include the holding area nurse, circulating nurse, scrub nurse or a non-nurse "scrub person," & specialty nurse.
examples of deep full thickness wounds

dermis
-thicker than the epidermis made of collagen, fibrous connective tissue, and elastic fibers -has blood vessels, sensory nerves, hair follicles, lymph vessels, sebaceous glands, sweat glands -can regrow ONLY if some dermis is present
inflammatory response
-triggers healing in the injured tissues -causes blood vessels to leak and WBCs to release chemicals -causes signs of the first 24-48 hours seen
burns larger than 35% TBSA
-use of urine output and VS to guide resuscitation aren't as adequate so invasive monitoring is needed
fasciotomy
-used if pressure remains elevated after a escharotomy -deeper incision extending through the fascia
Vacuum-assisted wound closure (VAC) negative pressure wound therapy (NPWT)
-used successfully to reduce/ close chronic ulcers by removing fluids or infectious materials from wound & enhancing formation of granulation tissue. -Requires that a suction tube be covered by a special sponge & sealed in place. -foam dressing changed q 48-72 hrs & not < 3x weekly. -continuous low-level negative pressure applied through suction tube. -should not be used in areas where skin cancer is located. -do not use if on anticoagulants or have exposed nerves, blood vessels or organs
exfoliative psoriasis
-very eruptive and inflammatory form of disease with generalized erythema and scaling -examine for signs of dehydration and hypothermia or hyperthermia r/t severe inflammatory reaction -can have reduced fluid volume through evaporative water loss from the skin surface
growth of anthrax
-vesicle appears -lesion may itch -often resembles insect bite -within a few days; vesicle becomes hemorrhagic and sinks inward -are of necrosis and ulceration begins -tissue around wound swells and can become swollen -eschar forms
Promoting sleep with itching
-wearing mittens or splints at night can help prevent inadvertent scratching during sleep. -A cool sleeping environment along with comfort measures such as a cool shower and application of moisturizers may help promote sleep. -moisturizers may help promote sleep. -Additional measures such as using sleep-promoting herbal teas or sedating antihistamines at bedtime
electrical injuries
-when an electrical current enters the body -results from electrical energy being converted to heat energy -"can't" let go, entrance wound and exit wound -occur in 3 ways: thermal, flash, true electrical

Considerations for older adults
Older adults are at particular risk for skin tears and pressure ulcers because of the presence of age-related skin changes. Progressive flattening of cells at the dermal-epidermal junction predisposes older people to skin tears from mechanical shearing forces, such as the removal of tape and friction from tightly applied restraints. In addition, skin moisture and irritation from incontinence combined with friction over bony prominences can lead to partial-thickness skin destruction and pressure ulcer formation. Patients with cognitive impairments may not readily report discomfort from inadequate pressure relief. If pressure is unrelieved, tissue destruction progresses to full-thickness injury.

• Pad the elbow if tucked at the side. • Avoid excessive abduction. • Secure arm firmly on a padded armboard, positioned at shoulder level, & extended < 90 degrees.
GI Complications of Surgery
• Paralytic ileus (few/ absent BS, distended abd, abd discomfort, vomiting, no flatus or stool) • GI ulcers and bleeding
Burns Pathopyhsiology
• Pathophysiology follows same path as w/adults • At first, vasodilatation. Then leaking of water, electrolytes and protein into the vasculature, causing edema
Pharmacologic Interruption of Pain Transmission
• Pharmacological target areas • Peripheral level- NSAIDs • CNS level- opioids
Prevention of Joint Complications (Stiffness, Pain, Inflammation, Limited Motion)
• Place a pillow or foam padding under bony prominences. • Maintain pt's extremities in good anatomical alignment. • Slightly flex joints & support w/ pillows, trochanter rolls, or pads.

Preparing the Client
• Possible placement of tubes, drains & vascular access devices • Teaching about postop procedures & exercises: • Breathing exercises, incentive spirometry, coughing & splinting • Leg exercises/procedures, anti-embolism stockings, pneumatic compression devices, ambulation, ROM exercises
Anxiety Interventions
• Preoperative teaching • Encouraging communication • Promoting rest • Using distraction • Teaching/including family and significant others
The patient with a pressure ulcer is expected to demonstrate progress to complete wound healing and not develop new pressure ulcers. Indicators include:
• Presence of granulation, re-epithelialization, and scar tissue formation • Decreased wound size • Absence of new pressure ulcers
Skin Complications of Surgery
• Pressure ulcers • Wound infection • Wound dehiscence • Wound evisceration • Skin rashes/contact allergies
Problems that increase the surgical risk or increase the risk for complications after surgery: Previous surgical procedures and anesthesia
• Previous experiences-may↑ anxiety • Ask about experience w/ anesthesia & allergies. • Family medical history & problems with anesthetics • Povidoneiodine (e.g., Betadine) for skin cleansing contains same allergens found in shellfish. Pts allergic to shellfish may have reaction to povidone-iodine. • Patient w/ allergy to bananas & other fruits may also have a latex sensitivity or allergy.
Circulating Nurse
• Protects the patient's privacy • Ensures the patient's safety • Monitors traffic in room • Assesses amt of urine & blood loss • Reports findings to surgeon & anesthesia provider • Ensures that surgical team maintain sterile technique & a sterile field • Anticipates pt's & surgical team's needs, providing supplies & equipment • Communicates info about the pt's status to family members during long or unique procedures • Documents care, events, interventions, & findings
Preventing Hypoventilation Evaluation: Outcomes

Changes Resulting From Burn Injury
• Pulmonary • Cardiac • GI (Curling's ulcer) • Metabolic • Immunologic
Problems that increase the surgical risk or increase the risk for complications after surgery: Medical History
• Pulmonary complications: older patients, pts w/ chronic resp problems, smokers d/t smoking- or age-related lung changes • ↑ chest rigidity & loss of lung elasticity reduce anesthetic excretion. • Smoking ↑ blood level of carboxyhemoglobin (carbon monoxide on oxygen-binding sites of the hemoglobin molecule), which ↓ O2 delivery to organs. • Action of cilia in pulmonary mucous membranes ↓ = retained secretions & predisposes to infection (pneumonia) & atelectasis (collapse of alveoli). • Atelectasis ↓ gas exchange & causes intolerance of anesthesia.
Complications of local or regional anesthesia
• R/T patient sensitivity to anesthetic (anaphylaxis), incorrect delivery technique, systemic absorption, & overdose. • Observe CNS stimulation followed by CNS & cardiac depression- signs of a systemic toxic reaction. • Assess for restlessness, excitement, incoherent speech, headache, blurred vision, metallic taste, nausea, vomiting, tremors, seizures, & increased pulse, respirations, & BP
General Anesthesia Intravenous Advantages
• Rapid and pleasant induction • Low incidence of postoperative nausea & vomiting • Requires little equipment
Opioid Receptors
• Receptors: mu, kappa, delta , nociceptin • For pain management, mu & kappa receptors are most important • delta connected w/ emotional & affective components of pain experience
Preoperative Medication
• Reduce anxiety • Promote relaxation • Reduce pharyngeal secretions • Prevent laryngospasm • Inhibit gastric secretions • Decrease amount of anesthetic needed for induction/maintenance of anesthesia
Increased use of "bloodless surgery" & minimally invasive surgery provides alternatives for patients w/ religious or medical restrictions to blood transfusions.
• Reduce need for transfusion during & after surgery. • Techniques used • limiting blood samples before surgery • Stimulating patient's own RBC production w/ epoetin alpha (Epogen, Procrit) before, during, & after surgery. • Supplemental Fe, folic acid, vitamin B12, & vitamin C before surgery to help RBC formation. • Newer equipment & surgical techniques = ↓ blood loss • recycling blood suctioned during surgery & immediately transfusing it back into patient. • Assess, monitor, teach, & support patient during bloodless surgery process.
Cryothermia Anesthesia Advantages
• Reflexes remain intact • Decreases chance of adverse reactions • Decreased intraoperative stress
Surgical procedures that are site-specific, such as left, right, or bilateral
• Require patient identification before surgery. • Site is marked by licensed independent practitioner & involves patient. • Practitioner is accountable & should be present during procedure. • Before starting procedure, facilities use "time-out" to verify correct site.

Opioid Agonists Adverse Effects:
• Resp. depression • Sedation • n/v • Physical/psychological dependence • Urinary retention • Constipation
Neuropathic Pain
• Results from injury to nerves • Burning, shooting, numbing • More difficult to manage w/conventional pain meds.
Bacterial Infection Pathophysiology
• S. aures & group A beta-hemolytic streptococci ○ Normal flora of skin • Nonbullous impetigo follows skin trauma or secondary bacterial infection • Both types of impetigo from toxin from S. aures • Folliculitis from occulsions of hair follicle • Cellulitis- localized infection usually from skin trauma • Staphylococcal scaled skin syndrome- infection with S. aureus that produces a toxin- causes exfoliation ○ Abrupt onset ○ Diffuse erythema ○ Skin tenderness
• Pathophysiology of Burn Injury
• Severity determined by how much of BSA is involved & depth of burn injury • Superficial thickness • Partial thickness • Full thickness • Deep full thickness • Degree of tiss. damage r/t what agent caused burn, temp. of heat source & how long skin exposed. • Differences in skin thickness in different areas of body can affect burn depth
Skin Assessment
• Size & depth of injury • % of total BSA affected • "Rule of nines" using multiples of 9% of total BSA
Gerontologic Considerations
• Skin tears • Thinning of the skin especially along lower legs and forearms • Senile purpura: type of hemorrhage under the skin due to thinner, more fragile bl. vess. Often occurs along with skin tears A greater number of comorbidities results in prolonged wound healing(poor cardiac output, ht. failure, DM, PVD, poor nutrition
Medication: Co-Morbidities for Decreased Tissue Repair
• Steroids decreases the effectiveness of the immune system by delaying white blood cell migration and fibroblasts, thus impacting the inflammatory phase of wound healing • Steroid use delays collagen synthesis, the regeneration of bl. vess. and epithelialization necessary for building healthy tissue • Methotrexate (chemo. drug) decreases the effectiveness of the immune system by bone marrow suppression and anemia
Emergency Care of the Patient with Malignant Hyperthermia (1/2)
• Stop all inhalation anesthetic agents & succinylcholine. • If endotracheal tube not already in place, intubate immediately. • Ventilate pt w/ 100% O2, using highest possible flow rate. • Administer dantrolene sodium (Dantrium) IV 2-3 mg/ kg. • Administer 100% O2. • If possible, terminate surgery. If not, continue using anesthetic agents that do not trigger MH • Assess ABGs & serum chemistries for metabolic acidosis & hyperkalemia. • metabolic acidosis- sodium bicarbonate IV. • hyperkalemia -10u reg insulin in 50mL 50% dextrose IV. • Use active cooling techniques: • Iced saline (0.9% NaCl) IV 15mL/kg q15min PRN • Cooling blanket over the torso. • Pack bags of ice around pt's axillae, groin, neck, & head.
Stress: Co-Morbidity
• Stress causes a release of glucocorticoids, reducing the production of cytokines, an essential component to the inflammatory process; thus inflammation becomes suppressed • Wound healing begins with inflammation, so if inflammation is delayed so is wound healing • Minimizing the pts stress level will promote the progression of wound healing (pain causes stress too)
Snoring or stridor
• Stridor: high-pitched crowing sounds • Occur w/ airway obstruction resulting from tracheal/ laryngeal spasm or edema, mucus in airway, blockage of airway
Pain Assessment
• Subjective experience for pts • Numerical scales & surveys assist in assessment & standardize perceptions • Effective pharmacotherapy depends on it • Assessment of degree of pain • Determining/understanding underlying disorders causing pain
Pain Assessment
• Subjective experience for pts • Numerical scales & surveys assist in assessment & standardize perceptions • Effective pharmacotherapy depends on it • Assessment of degree of pain • Determining/understanding underlying disorders causing the pain
Prevention of Radial Nerve Complications (Wrist Drop)
• Support the wrist with padding. • Be careful not to overtighten wrist straps.
Nutritional status Malnutrition
• Surgery ↑ metabolic rate & depletes K+, vitamin C, & B vitamins, all needed for wound healing & blood clotting. • ↓ serum protein levels slow recovery. • (-) nitrogen balance- from depleted protein stores. • ↑ risk for skin breakdown, delayed wound healing, possible dehiscence or evisceration, dehydration, & sepsis.

Problems that increase the surgical risk or increase the risk for complications after surgery: Drugs and substance use
• Tobacco use increases risk for pulmonary complications • Excessive alcohol & illicit substance use can alter patient's responses to anesthesia & pain medication. • Withdrawal of alcohol before surgery may lead to delirium tremens. • Prescription & OTC drugs may also affect how the patient reacts to the operative experience. • Adverse effects can occur with use of some herbs
Opioid Dependence
• Tolerance & physical dependence develops very quickly • When attempting to d/c, withdrawal symptoms can be very uncomfortable • To feel "normal" must continue w/ opioid • Withdrawal symptoms last from 7d - yrs • Potential for physical & psychological dependence

Arterial Ulcer
◦ Arterial Insufficiency Ulcers are caused by arteriosclerosis which leads to insufficient oxygenation of skin & underlying tissues. This injures & affected tissues & causes wounds. ◦ Wounds are very dry, painful, pt. likes to sit up w/ legs dangling ◦ Hair loss & shiny skin ◦ Pallor with elevation ◦ Dependent rubor ◦ dangle- pink/red
Pressure Ulcer Interventions
◦ Daily inspection of skin, skin washed w/ soap & water, creams/lotions used to moisturize, barrier ointment whenever incontinence is present, absorbent pads/ garments changed after each incontinence ◦ Reddened areas are never massaged
Wound Assessment
◦ Document initial assessment, including location, size, color, extent of tiss. involvement, exudate, condition of surrounding tissue ◦ Assess/document wound at ea. dressing change ◦ Assess/document for blanching(area lightens with pressure) ◦ Types of wound exudate, p. 443 ◦ Record location & size using mm/cms. ◦ Measure depth as distance from deepest portion of wound to skin level ◦ Inspect wound margins for inflammation extending beyond area of injury ◦ Inspect for eschar (black, brown or gray)necrotic tissue ◦ Assess for odor
◦ Venous System Determinants in Circulation
◦ Edema ◦ Hemosiderin staining: RBCs become trapped in interstitial tissues; breakdown of heme, or iron, into tissue itself ◦ Venous Insufficiency: Doppler tests using US to measure venous congestion or regurgitation (a direct result of incompetent valves)
Unstageable Pressure Ulcer
◦ Full thickness tiss loss ◦ The base of ulcer is completely covered by slough (yellow, tan, gray, green or brown) &/or eschar (tan, brown or black) in wound bed. (Slough usually soft, eschar is hard) ◦ The true depth of wound is obscured
Stage IV Pressure Ulcer
◦ Full thickness tiss loss w/exposed bone, tendon or muscle. ○ Slough or eschar may be present on some parts of wound bed. ○ Often include undermining & tunneling ◦ Exposed bone/tendon is visible or directly palpable. ◦ Monitor for undermining (tissue damage that occurs under healthy appearing skin surrounding ulcer
Stage I Pressure Ulcer
◦ Intact skin w/non-blancheable redness of a localized area usually over a boney prominence. ○ Darkly pigmented skin may not have visible blanching; its color may differ from surrounding skin ◦ Area may be painful, firm, soft, warmer/ cooler as compared to adjacent tiss. May be difficult to detect with dark skin tones
Factors Contributing to Pressure Ulcers
◦ Limited mobility ◦ Sensory impairment ◦ Friction & shear ◦ Excessive skin moisture ◦ Nutritional status ◦ Incontinence ◦ Prolonged contact of the skin with urea, bacteria, yeast & enzymes carried in urine/feces
Risk Factors That Impact Wound Healing
◦ Nutrition & Hydration ◦ Infection ◦ Comorbidities ◦ Medications ◦ Stress ◦ Glucose control & diabetic management ◦ Smoking ◦ Gerontological considerations &comorbidities
Venous Insufficiency
◦ Occurs as a result of prolonged venous hypertension that stretches veins & damages valves ◦ Valvular damage can lead to a backup of blood & further venous HTN ◦ Results: edema, ↓ tiss. perfusion ◦ In time, stasis results in venous stasis ulcers, edema & cellulitis
Types of Wounds
◦ Pressure ulcers-area of localized damage caused by ischemia because of pressure ◦ Surgical incision-the cutting of/or into body tissues/organs as part of an operation ◦ Venous ulcers-are lesions that develop in the lower extremities from chronic venous insufficiency ◦ Arterial ulcers(ischemic ulcers)-occur d/t severe tiss. ischemia and are extremely painful ◦ Diabetic ulcers-results from damaged nerves, metabolic changes and peripheral artery disease changes
Pressure Ulcer Interventions: Positioning
◦ Pressure-relief devices: specialty beds, mattress replacements, wedges ◦ Pt. positioned at HOB at 30 degrees (applies to side-lying, also) ◦ If lying in this position is a problem, may prop pt at >90 with pillows at back to get pressure off sacrum ◦ Positioning in w/c ◦ Prevention of heel ulcers ◦ Pt should be on individualized schedule turning
Risk Factors Affecting The Rate of Wound Healing
◦ The vascular component to healing is most essential of all components; wo it, no phase/hope of healing can occur ◦ Vascular circulation consists of: ○ Macrocirculation ○ Microcirculation ◦ Vascular system delivers O2, leukocytes, macrophages, prostaglandins, growth factors...all contribute to healing process
Diabetic Ulcer
◦ There is a chain of events that lead to development of a diabetic foot ulcer. ◦ In general, most common precipitating event is trauma to foot of a person w/diabetes. ◦ Ex: irritation to foot caused by poorly-fitting shoes, calluses left untreated, trimming of toenail, burn injury to foot, cut (laceration) of foot ◦ Penetrating injury to foot from a sharp object, insect bite to foot ◦ 2 other conditions that predispose diabetic patient to develop foot ulcers: ◦ Peripheral neuropathy ◦ Peripheral vascular disease
Suspected Deep Tissue Injury (DTI)
◦ This area may present as painful, firm, mushy, boggy, warmer or cooler as compared to adjacent tissue ◦ Purple or maroon localized area of discolored intact skin or blood-filled blister d/t damage of underlying soft tiss from pressure and/or shear.
Venous Ulcer
◦ Ulcers caused by increased pressure of blood in the veins of the lower leg. ◦ This causes fluid to ooze out of the veins beneath the skin. ◦ This causes swelling, thickening and damage to the skin. ◦ The damaged skin may eventually break down to form a shallow ulcer. ◦ See Lower Extremity Ulcers, p. 721
Stage III Pressure Ulcer
◦Full thickness tiss loss. ○ Subcutaneous fat may be visible but bone, tendon or muscle are not exposed. ○ Slough may be present but does not obscure the depth of tiss loss. ○ May include undermining/tunneling ◦The bridge of nose, ear, occipital & malleolus do not have subcut. tiss. & stage III ulcers can be shallow.
