Copyright © 2008 Wolters Kluwer Health | Lippincott Williams & Wilkins Chapter 38 Skin Integrity and Wound Care

Copyright © 2008 Wolters Kluwer Health | Lippincott Williams & Wilkins Six Functions of the Skin Protection Body temperature regulation Sensation Excretion Maintenance of water and electrolyte balance Vitamin D production and absorption

Copyright © 2008 Wolters Kluwer Health | Lippincott Williams & Wilkins Question Tell whether the following statement is true or false. Blood vessels in the skin dilate to dissipate heat. A. True B. False

Copyright © 2008 Wolters Kluwer Health | Lippincott Williams & Wilkins Answer Answer: A. True Blood vessels in the skin dilate to dissipate heat.

Copyright © 2008 Wolters Kluwer Health | Lippincott Williams & Wilkins Cross-Section of Normal Skin

Copyright © 2008 Wolters Kluwer Health | Lippincott Williams & Wilkins Factors Affecting the Skin Unbroken and healthy skin and mucous membranes defend against harmful agents Resistance to injury is affected by age, amount of underlying tissues, and illness Adequately nourished and hydrated body cells are resistant to injury Adequate circulation is necessary to maintain cell life

Copyright © 2008 Wolters Kluwer Health | Lippincott Williams & Wilkins Developmental Considerations Infant’s skin and mucous membranes are easily injured and subject to infection Child’s skin becomes increasingly resistant to injury and infection –Requires special care because of toilet and play habits Adolescent has enlarged sebaceous glands and increased secretions Adult’s tissue becomes thinner and wrinkles appear; liver spots occur

Copyright © 2008 Wolters Kluwer Health | Lippincott Williams & Wilkins Causes of Skin Alterations Very thin and very obese people are more susceptible to skin injury –Fluid loss during illness causes dehydration –Skin appears loose and flabby Excessive perspiration during illness predisposes skin to breakdown Jaundice causes yellowish, itchy skin Diseases of the skin cause lesions that require care

Copyright © 2008 Wolters Kluwer Health | Lippincott Williams & Wilkins Factors Influencing Personal Hygiene Culture Socioeconomic class Spiritual practices Developmental and knowledge level Health state Personal preference

Copyright © 2008 Wolters Kluwer Health | Lippincott Williams & Wilkins Types of Wounds Intentional or unintentional Open or closed Acute or chronic Partial thickness, full thickness, complex

Copyright © 2008 Wolters Kluwer Health | Lippincott Williams & Wilkins Question Which one of the following types of wounds is caused by a blunt instrument that causes injury to underlying soft tissue with the overlying skin remaining intact? A. Contusion B. Abrasion C. Laceration D. Avulsion

Copyright © 2008 Wolters Kluwer Health | Lippincott Williams & Wilkins Answer Answer: A. Contusion Rationale: A contusion is caused by a blunt instrument and may result in bruising or hematoma. An abrasion is the rubbing or scraping of epidermal layers of skin. A laceration is the tearing of skin and tissue with a blunt or irregular instrument. Avulsion is the tearing of a structure from normal anatomic position.

Copyright © 2008 Wolters Kluwer Health | Lippincott Williams & Wilkins Principles of Wound Healing Intact skin is the first line of defense against microorganisms Surgical asepsis is used in caring for a wound The body responds systematically to trauma of any of its parts An adequate blood supply is essential for normal body response to injury Normal healing is promoted when wound is free of foreign material

Copyright © 2008 Wolters Kluwer Health | Lippincott Williams & Wilkins Principles of Wound Healing (cont.) The extent of damage and the person’s state of health affects wound healing Response to wound is more effective if proper nutrition is maintained

Copyright © 2008 Wolters Kluwer Health | Lippincott Williams & Wilkins Phases of Wound Healing Inflammatory Proliferative Remodeling

Copyright © 2008 Wolters Kluwer Health | Lippincott Williams & Wilkins Question In which one of the following phases of wound healing is new tissue built to fill the wound space, primarily through the action of fibroblasts? A. Hemostasis B. Inflammatory phase C. Proliferation phase D. Maturation phase

Copyright © 2008 Wolters Kluwer Health | Lippincott Williams & Wilkins Answer Answer: C. Proliferation phase Rationale: In the proliferation phase, granulation tissue is formed to fill the wound. In hemostasis, involved blood vessels constrict and blood clotting begins. In the inflammatory phase, white blood cells move to the wound. In the maturation phase, collagen is remodeled forming a scar.

Copyright © 2008 Wolters Kluwer Health | Lippincott Williams & Wilkins Inflammatory Phase Begins at time of injury Prepares wound for healing –Hemostasis (blood clotting) occurs –Vascular and cellular phase of inflammation

Copyright © 2008 Wolters Kluwer Health | Lippincott Williams & Wilkins Proliferative Phase Phase begins within 2 to 3 days of injury and may last up to 2 to 3 weeks New tissue is built to fill wound space through action of fibroblasts Capillaries grow across wound Thin layer of epithelial cells forms across wound Granulation tissue forms foundation for scar tissue development

Copyright © 2008 Wolters Kluwer Health | Lippincott Williams & Wilkins Remodeling Phase Final stage of healing begins about 3 weeks after injury to possibly 6 months Collagen is remodeled New collagen tissue is deposited Scar becomes a flat, thin, white line

Copyright © 2008 Wolters Kluwer Health | Lippincott Williams & Wilkins Factors Affecting Wound Healing Age—children and healthy adults heal more rapidly Circulation and oxygenation—adequate blood flow is essential Nutritional status—healing requires adequate nutrition Wound condition–specific condition of wound affects healing Health status—corticosteroid drugs and postoperative radiation therapy delay healing

Copyright © 2008 Wolters Kluwer Health | Lippincott Williams & Wilkins Wound Complications Infection Hemorrhage Dehiscence and evisceration Fistula formation

Copyright © 2008 Wolters Kluwer Health | Lippincott Williams & Wilkins Question Which one of the following wound complications is caused by overhydration related to urinary and fecal incontinence? A. Necrosis B. Edema C. Desiccation D. Maceration

Copyright © 2008 Wolters Kluwer Health | Lippincott Williams & Wilkins Answer Answer: D. Maceration Rationale: Maceration is caused by overhydration related to incontinence that causes impaired skin integrity. Necrosis is dead tissue present in the wound that delays healing. Edema is swelling at a wound site that interferes with blood supply to the area. Desiccation is the process in which the cells dehydrate and die.

Copyright © 2008 Wolters Kluwer Health | Lippincott Williams & Wilkins Factors Affecting Pressure Ulcer Development Aging skin Chronic illnesses Immobility Malnutrition Fecal and urinary incontinence Altered level of consciousness Spinal cord and brain injuries Neuromuscular disorders

Copyright © 2008 Wolters Kluwer Health | Lippincott Williams & Wilkins Mechanisms in Pressure Ulcer Development External pressure compressing blood vessels Friction or shearing forces tearing or injuring blood vessels

Copyright © 2008 Wolters Kluwer Health | Lippincott Williams & Wilkins Stages of Pressure Ulcers Stage I — nonblanchable erythema of intact skin Stage II — partial-thickness skin loss Stage III — full-thickness skin loss; not involving underlying fascia Stage IV — full-thickness skin loss with extensive destruction

Copyright © 2008 Wolters Kluwer Health | Lippincott Williams & Wilkins A Wound with Various Types of Wound Surface Tissue

Copyright © 2008 Wolters Kluwer Health | Lippincott Williams & Wilkins Question Tell whether the following statement is true or false. A Stage III pressure ulcer requires debridement through wet-to-dry dressings, surgical intervention, or proteolytic enzymes. A. True B. False

Copyright © 2008 Wolters Kluwer Health | Lippincott Williams & Wilkins Answer Answer: A. True A Stage III pressure ulcer requires debridement through wet-to-dry dressings, surgical intervention, or proteolytic enzymes.

Copyright © 2008 Wolters Kluwer Health | Lippincott Williams & Wilkins Cleaning a Pressure Ulcer Clean with each dressing change Use careful, gentle motions to minimize trauma Use 09% normal saline solution to irrigate and clean the ulcer Report any drainage or necrotic tissue

Copyright © 2008 Wolters Kluwer Health | Lippincott Williams & Wilkins Dressing the Pressure Ulcer Keep ulcer tissue moist and surrounding skin dry Place moist dressings only on the wound surface Use dressing that absorbs exudate but maintains moist environment Use skin sealant or moisture-barrier ointment on surrounding skin Secure dressing with the least amount of tape possible Use wet-to-dry dressings for debridement, when ordered Pack wound cavities loosely with dressing material

Copyright © 2008 Wolters Kluwer Health | Lippincott Williams & Wilkins Wound Assessment Inspection for sight and smell Palpation for appearance, drainage, and pain Sutures, drains or tube, manifestation of complications

Copyright © 2008 Wolters Kluwer Health | Lippincott Williams & Wilkins Presence of Infection Wound is swollen Wound is deep red in color Wound feels hot on palpation Drainage is increased and possibly purulent Foul odor may be noted Wound edges may be separated with dehiscence present
