SKIN STRUCTUREEPIDERMIS

• Outermost Layer

• Barrier-restricts water loss

• Prevents fluids, pathogens and chemicals from entering

Page 3: SKIN INTEGRITY AND WOUND HEALING FALL 2010. SKIN STRUCTURE EPIDERMIS Outermost Layer Barrier-restricts water loss Prevents fluids, pathogens and chemicals

SKIN STRUCTUREDERMIS

• Below epidermis and above subcutaneous tissue• Composed of connective tissue • Provides strength and elasticity to

skin• Contains blood vessels• Contains sweat glands, ceruminous

glands, hair and nail follicles, sensory receptors, elastin and collagen

Page 4: SKIN INTEGRITY AND WOUND HEALING FALL 2010. SKIN STRUCTURE EPIDERMIS Outermost Layer Barrier-restricts water loss Prevents fluids, pathogens and chemicals

SKIN STRUCTURESUBCUTANEOUS LAYER

• Composed of fat and connective tissue

• Provides insulation, protection and a reserve of calories in the event of severe malnutrition

• Thickness and distribution varies-influenced by hormones, genetics, age and nutrition

FACTORS INFLUENCING ABILITY TO MAINTAIN INTACT SKIN AND HEAL

WOUNDS

• Age• Mobility• Nutrition• Hydration• Diminished Sensation• Impaired Circulation• Medications

Page 6: SKIN INTEGRITY AND WOUND HEALING FALL 2010. SKIN STRUCTURE EPIDERMIS Outermost Layer Barrier-restricts water loss Prevents fluids, pathogens and chemicals

FACTORS INFLUENCING ABILITY TO MAINTAIN INTACT SKIN AND HEAL

WOUNDS

• Moisture on the skin• Fever• Contamination• Lifestyle (Smoking)• Disease processes• Radiation treatments• Immune function

Page 7: SKIN INTEGRITY AND WOUND HEALING FALL 2010. SKIN STRUCTURE EPIDERMIS Outermost Layer Barrier-restricts water loss Prevents fluids, pathogens and chemicals

WOUND CLASSIFICATIONS• Status of skin integrity

• Descriptive qualities• Abrasion• Laceration• Contusion

Page 9: SKIN INTEGRITY AND WOUND HEALING FALL 2010. SKIN STRUCTURE EPIDERMIS Outermost Layer Barrier-restricts water loss Prevents fluids, pathogens and chemicals

WOUND HEALING METHODS

• Regenerative• Affects only epidermal layer• No scar

• Primary Intention• Edges well approximated• Little scarring

Page 10: SKIN INTEGRITY AND WOUND HEALING FALL 2010. SKIN STRUCTURE EPIDERMIS Outermost Layer Barrier-restricts water loss Prevents fluids, pathogens and chemicals

WOUND HEALING METHODS cont

• Secondary Intention

• Wound edges not approximated• Heals from inner layer• Beefy red granulation tissue• More scar tissue• Increased chance of infection or

complications

Page 11: SKIN INTEGRITY AND WOUND HEALING FALL 2010. SKIN STRUCTURE EPIDERMIS Outermost Layer Barrier-restricts water loss Prevents fluids, pathogens and chemicals

WOUND HEALING METHODS cont.

• Tertiary Intention

•Delayed wound closure•Two surfaces of granulation

tissue brought together•More scarring than primary but

less than secondary

WOUND HEALING PHASES

• Inflammatory-Cleansing• 1-5 days• Homeostasis-Provides clotting• Inflammation-Provides sealing scab

• Proliferative-Granulation• 5-21 days

PRESSURE ULCERS

• Chronic wound• AKA bedsore, pressure sore,

decubitus ulcer

Page 17: SKIN INTEGRITY AND WOUND HEALING FALL 2010. SKIN STRUCTURE EPIDERMIS Outermost Layer Barrier-restricts water loss Prevents fluids, pathogens and chemicals

Pressure UlcerPrevention

• Intrinsic risk factors• Immobility• Impaired sensation• Malnourishment

• Extrinsic risk factors• Friction• Shearing• Moisture• Pressure

Page 18: SKIN INTEGRITY AND WOUND HEALING FALL 2010. SKIN STRUCTURE EPIDERMIS Outermost Layer Barrier-restricts water loss Prevents fluids, pathogens and chemicals

Pressure Ulcer Prevention

• Assess skin daily (q shift)• Pressure points

• Keep clean and dry• Warm water & mild soap

• Moisturizing lotions• Linen soft, clean, dry, no wrinkles• Adequate calories, protein, fluids• Reposition q 2 hours• Therapeutic Mattresses

• Air, gel, foam, water (AHRQ)

Page 19: SKIN INTEGRITY AND WOUND HEALING FALL 2010. SKIN STRUCTURE EPIDERMIS Outermost Layer Barrier-restricts water loss Prevents fluids, pathogens and chemicals

Pressure Ulcer Risk Assessment• Braden Scale (low score = high risk)

• Sensory perception• Moisture• Activity• Mobility• Nutrition• Friction & shear

Norton Scale (low score = high risk)• Physical condition• Mental state• Activity• Mobility• Incontinence

Page 20: SKIN INTEGRITY AND WOUND HEALING FALL 2010. SKIN STRUCTURE EPIDERMIS Outermost Layer Barrier-restricts water loss Prevents fluids, pathogens and chemicals

Pressure Ulcer Staging• Stage I Nonblanchable erythema

(>30mins after pressure removed)

– Intact skin• Stage II Partial thickness skin loss

– (epidermis / dermis)– Shallow crater, blister, or abrasion

• Stage III Full thickness skin loss– Necrosis of subcutaneous tissue;

undermining may be present• Stage IV Full thickness skin loss

– Extensive damage to muscle, bone; undermining and sinus tracts may be present

CONTROLLING INFECTION

• Closed Wounds-Standard Precautions• Open Wounds-Contact Precautions• Multiple Wounds-Treat least

contaminated wound first.• Acute wounds may require sterile

technique• Chronic wounds-clean technique

HEAT AND COLD THERAPY

• Avoid direct skin contact with heating or cooling device.

• Leave on patient no more than 15 minutes at a time in an area.

• Check skin frequently for extreme redness, blistering, cyanosis, or blanching.

Page 31: SKIN INTEGRITY AND WOUND HEALING FALL 2010. SKIN STRUCTURE EPIDERMIS Outermost Layer Barrier-restricts water loss Prevents fluids, pathogens and chemicals

HEAT AND COLD THERAPY

• Heat relieves stiffness and discomfort, promotes delivery of nutrients and removal of waste products from tissue, and promotes relaxation.

• Cold causes vasoconstriction and decreases capillary permeability, produces local anesthesia, reduces cell metabolism, increases blood viscosity, slows bacterial growth and decreases muscle tension

Page 32: SKIN INTEGRITY AND WOUND HEALING FALL 2010. SKIN STRUCTURE EPIDERMIS Outermost Layer Barrier-restricts water loss Prevents fluids, pathogens and chemicals

HEAT AND COLD THERAPY

• Heat can cause a drop in blood pressure and a feeling of faintness.

• Cold can elevate blood pressure, cause shivering, and produce tissue damage due to impaired circulation
