procedure for negative pressure wound therapy
*Use sterile gloves *Cut the foam to the shape and measurement of the wound *Place the drape to cover the wound and an additional 3-5 cm *Cut a 2-cm hole in the drape *Apply a vacuum device to wound *Ensure that negative pressure has been achieved
circulation
02 needed or healing is slowed hense ulcers secondary to venous insufficiency and pressure ulcers are so difficult to heal. When hemoglobin is reduced by more than 15% , like with severe anemia healing is impaired.
psoriases

types of wounds
A laceration wound can be described as a separation of skin and tissue in which the edges are torn and irregular. ragged edges torn tissue An incision wound is described as a clean separation of skin and tissue with a smooth, even edge. An abrasion is a wound in which the surface layers of skin are scraped away. Friction to the skin Ulceration is a shallow crater in which skin or mucous membrane is missing. A puncture wound is a wound that occurs from penetration of the skin and underlying tissue
stages of pressure ulcers
A stage I pressure ulcer is a defined area of intact skin with nonblanchable redness of a localized area usually over a bony prominence. Darkly pigmented skin may not have visible blanching; its color may differ from the surrounding skin. The area may be painful, firm, soft, warmer, or cooler as compared to adjacent tissue. A stage II pressure ulcer involves partial thickness loss of a little bid of the dermis and presents as a shallow, open ulcer. A stage II could present as a blister, abrasion, or shallow crater. So it will go through the prelifiration stage of healing but won't go through granulation as granulation happens at subcutaneos or below A stage III ulcer presents with full-thickness tissue loss. Subcutaneous fat may be visible, but bone, tendon, or muscle is not exposed. Slough that may be present does not obscure the depth of tissue loss. Ulcers at this stage may include undermining and tunneling. at proliferation there will be granulation as it is deeper. Stage IV ulcers involve full-thickness tissue loss with exposed bone, tendon, or muscle. Slough or eschar may be present on some part of the wound bed and often include undermining and tunneling

sweat glands
The eccrine sweat glands are found in all areas of the skin. Their ducts open directly onto the skin surface. The thin, watery secretion called sweat is produced in the basal, coiled portion of the eccrine gland and is released into its narrow duct. The apocrine sweat glands are larger than eccrine sweat glands and are located in the axillae, anal region, scrotum, and labia majora. Their ducts generally open onto hair follicles. The apocrine glands become active at puberty. In women, they enlarge and recede with each menstrual cycle. Apocrine glands produce a milky sweat that is sometimes broken down by bacteria to produce the characteristic underarm odor.
pressure ulcer
Result of the impeding of capillary blood flow to the skin or underlying tissue: • "Pressure ulcers usually occur over bony prominences where body weight is distributed over a small area without much subcutaneous tissue." • "The skin can tolerate considerable pressure without cell death, but for short periods only." • "The duration of pressure, compared to the amount of pressure, plays a larger role in pressure ulcer formation." Pressure ulcers can develop in a variety of locations where bony prominences are located on a client. The most common are the coccyx and sacrum. A pressure ulcer can appear in less than 2 hours of time, depending on the factors present. Shearing force results when one layer of tissue slides over another layer. Patients who are pulled rather than lifted when being moved up in bed or from bed to chair to stretcher are at risk for injury from shearing forces
age consideration for skin conditions
The nurse would find liver spots in the older adult client. Also called senile lentigines, liver spots are pigmentation changes that occur on sun-exposed areas. Milia, lanugo, and acne vulgaris are not found in older adults. Milia are sebaceous retention cysts seen as white, opalescent spots around the chin and nose that appear during the first few weeks of life. Lanugo is fine hair that covers the body of the newborn. Acne vulgaris is a common skin disorder found in adolescents
heat and cold best practices
The nurse would make more frequent checks of the skin of an older adult using a heating pad. The nurse would fill an ice bag with small pieces of ice to about two-thirds full. The nurse would cover a cold pack with a cotton sleeve to keep it in place on an arm. The nurse would place cold therapy on a sprained wrist in the acute stage. The nurse would instruct the client not to lie or lean directly on the heating device. The nurse would apply moist cold to a client's eye for 30 minutes, every 2 hours.
dermis layer made up of
The true skin The dermis is the thickest layer of skin; it is primarily made up of fibroblast cells, which are important in remodeling and repair of skin. This connective tissue layer contains nerve endings, sensory receptors, capillaries, and elastic fibers. This layer has two zones, the papillary dermis and reticular dermis. The papillary dermis lies directly beneath the epidermis and is composed primarily of fibroblast cells capable of producing one form of collagen, a component of connective tissue The reticular layer lies beneath the papillary layer and also produces collagen and elastic bundles.
drainage
Serosanguineous pale pink-yellow, thin, and contains plasma and red cells Serous drainage is pale yellow and watery, like the fluid from a blister Sanguineous drainage is bloody, as from an acute laceration. Purulent drainage contains white cells and microorganisms and occurs when infection is present. It is thick and opaque and can vary from pale yellow to green or tan, depending on the offending organism.

what is happening during the partial thickness wound repair
a partial thickness wound has lost epidermis and some dermis, open shallow ulcer no slough or bruising healing involves hemeostasis and then inflammation and then during the proliferated phase epithelialization happens (epidermal cells, which appear pink, migrate across the surface of the wound. Once covered cells continue to reproduce until skin is normal. you will use foams like hydrophilic, hydrogels, collagens. a superficial partial thickness burn is first degree, epidermus pink and red no blister a moderate partial thickness burn is second degree and pink pale yellow-brown.

types of dressings 3 main types
for absorption use gauze, hyrocholoid, for maintanane transparent film for dry wound TRANSPARENT FILMS adhesive semipermeable film dressings. Transparent dressing allows the nurse to assess a wound without removing the dressing; transparent dressings are especially used for peripheral and IV insertion sites FOAMS absorption and protection. hydrophilic polyurethrane used for partial and full thickness wounds with small to moderate drainage; foams provide HYDROCOLLOIDS hydrophilic colloid particles attached to a backing. The nurse uses a hydrocolloid dressing when caring for a client with superficial burn wounds as hydrocolloid dressings are self-adhesive, opaque, air- and water-occlusive wound coverings that keep wounds moist. Hydrocolloids would be used with light to moderate drainage and no infection. Hydrogels work with wounds that have minimal exudate HYDROGELS encourage granulation within full thickness wounds to provide comfort in tender, partial thickness wounds to assist in autolytic debridement of nectotic tissue in full thickness wounds. ALGINATE used for absorption, indicated for deep or moderately draining wounds. Antimicrobial dressings are appropriate for chronic wounds at risk for infection COLLAGENS contain collagen a major protein in the body for partial and full thickness wounds COMPOSITS dressings that combine 2 or more products to facilitate application and use. CONTACT LAYER nonadherent dressings that will not stick to wound surface, minimizes distruption of new cells SILVER DRESSINGS antimicrobial dressings used for infected wounds. GAUZE Gauze dressing is ideal for covering fresh wounds because of its highly absorbent nature. Gauze is applied to fresh wounds that are likely to bleed or wounds that exude drainage. For a patient with copious amounts of exudate, use these dressings • Alginates • Antimicrobials • Composites Types of dressing that would be appropriate with this type of wound are alginates, antimicrobials, and composites. These all work with heavy drainage and infected wounds.

types of dressings
iodofoam is the long gauze ALGINATE DRESSINGS highly absorbant, go inside the wound, required to be covered, used for deep moderately draining wounds. GAUZE highly absorbent, allows 02 and can be saturated in saline, good for new surgical incisions, packing wounds HYDROCOLLOID WAFER DRESSING adhesive backed pad normally tanned and keep environment away from wound, moderately absorption. good for partial thickness wounds, shallow to full thickness wounds. HYDROGEL high % of water in matrix, sheetlike wafer causes cooling or can come in a tube of gel. good for partial thickness wounds, stages 2-4, cover dressing with gauze, good for minor burns or skin graft donor sites. POLYURETHANE FOAM pads of compressed foam, vary in thickness, sometimes adhesive, mild to moderate absorption, provide a moist wound surface, good for partial thickness wounds, absorbent covering for deep wounds that have been packed with a primary dressing. TRANSPARENT DRESSING clear film, maintain moist wound, no absorptive properties, good for Ivs, or wounds with minimal exudate.
dehiscence
is a total or partial disruption in wound edges. same as separation. wound separates but underlying subcutaneous tissue has not parted. drainage normally increases. obesity, poor nutrition, increased stress on incisional area increases risk.
denuded skin
is the loss of the epidermal layer of skin. can occur on buttocks or perineal area, result of urinary or fecal incontinence.
cyanosis
late sign and symptom of hypoxemia, as 5 g of hemoglobin (normal level is 15 g/dL) are desaturated before cyanosis is evident. In cases of carbon monoxide poisoning, the level of carboxyhemoglobin does not affect color, therefore the patient may be profoundly hypoxemic without evidence of cyanosis.

SDTI suspected deep tissue injury
during stage 2 there is Partial-thickness loss of dermis presenting as a shallow open ulcer with a red-pink wound bed, without slough. May also present as an intact or open/ruptured serum-filled blister. Presents as a shiny or dry shallow ulcer without slough or bruising (bruising indicates suspected deep tissue injury [DTI]). This stage should not be used to describe skin tears, tape burns, perineal dermatitis, maceration, or excoriation. Purple or maroon localized area of discolored intact skin or blood-filled blister due to damage of underlying soft tissue from pressure and/or shear. The area may be preceded by tissue that is painful, firm, mushy, boggy, warmer, or cooler as compared to adjacent tissue. DTI may be difficult to detect in individuals with dark skin tones. Evolution may include a thin blister over a dark wound bed. The wound may further evolve and become covered by thin eschar. Evolution may be rapid, exposing additional layers of tissue even with optimal treatment
epithelialization
process in which pink epidermal cells reproduce and migrate over the surface of the partial thickness wound
desquamation
process in which thin outermost layer of epidermis continuously sheds.
evisceration
protrusion of internal organs through an open wound. What to do with an evisceration of an abdominal wound after a coughing episode. A client who has an evisceration of a wound is a medical emergency. The client should be placed in a low Fowler's position and, with the use of sterile techniques, the eviscerated structures should be covered with normal saline-moistened gauze. The surgeon should also be notified. The nurse should never reinsert protruding structures or apply a pressure dressing. This could cause the tissue to be injured

4 overlapping stages of the regenerative process
regenerative process is once you have a wound and how it heals STAGE 1 HEMOSTASIS Hemostasis involves the constriction of blood vessels and the beginning of blood clotting immediately after the initial injury.is the skins response to 2 immediate threats, 1, you are losing blood and 2, the barrier of the skin is compromised. blood vessels tighten together to plug the hole clogging it = vasocontriction. Now the protein called fibrin creates crosslinks on the top of the skin to prevent blood from flowing out and stops bacteria and pathogens from getting in. This takes about 3 hrs and the skin begin to turns red dignalling. Hemostasis involves the constriction of blood vessels and the beginning of blood clotting immediately after the initial injury stage 2 STAGE 2 INFLAMMATION bleeding is under control and barrier is secured so the body expands the blood vessels, (vasodilation) in order to send cells like wbc, (macrophages) to fight any pathogens that maybe got through, the macrophages phagotyze the pathogens or any damaged tissues by consuming them this is called phagocytosis. They also produce growth factors to spur healing. The inflammatory phase lasts about four to six days, and white blood cells and macrophages move to the wound. white blood cells and macrophages move to the wound. After 2 to 3 days after the wound the 3rd stage starts STAGE 3 PROLIFERATIVE has 2 types A) For partial thickness the epidermal cells, pink, produce and migrate across the surface of the wound. epithelialization) B) For full thickness The proliferation phase is characterized by the formation of granulation tissue (highly vascular, red tissue that bleeds easily). During the proliferation phase, new tissue is built to fill the wound space fibroblast cells enter the wound and produce collagen, which is a fibrous protein. The collagen forms connective skin tissue to replace the fibrin from before, epidermal cells divide and reform the outer layer of skin, the dermis contracts to help close the wound. The proliferation phase is characterized by the formation of granulation tissue (highly vascular, red tissue that bleeds easily). During the proliferation phase, new tissue is built to fill the wound space. 4th STAGE IS MATURATION/REMODELING the wound matures as the newly deposited collagen is rearranged and converted into specific types of collagen, this process can take over a year blood vessels connect and strengthen. new tissue can reach 50 to 80% of its original healthy function depending on the severity of the initial wound. The skin doesn't fully recover so scarring occurs. The maturation phase is the final phase of wound healing and involves remodeling of collagen that was haphazardly deposited in the wound; in addition, a scar forms. The nurse should understand that the integrity of the skin and damaged tissues is restored through resolution or the process by which damaged cells recover and re-establish their normal function, regeneration or cell duplication, and scar formation, which is the replacement of damaged cells with fibrous tissues. Leukocytosis means the increased production of white blood cells; whereas, phagocytosis is the process by which white blood cells consume pathogens, coagulated blood, and cellular debris.
surgical wound complications
remember that insufficient protein and vitamin C intake, weak tissue, muscular support due to obesity, and distension of the abdomen from accumulated intestinal gas are the likely causes of surgical complications. Premature removal of sutures or staples; unusual strain on the incision from severe coughing, sneezing, vomiting, dry heaves, or hiccupping; or compromised tissue integrity from previous surgical procedures in the same area are some of the other causes of surgical complication. Compromised blood circulation and serous fluid accumulation that prevents skin tissue approximation are the factors that interfere with wound healing.
debridement
removal of foreign material or dying tissue from a wound. SURGICAL DEBRIDEMENT using sharp instrument to debride the wound. done during surgery and bedside. Must specialize in this ENZYMATIC DEBRIDEMENT placing chemical products, like collagenase within the wound to help break down the necrotic debris AUTOLYTIC DEBRIDEMENT uses the bodys own fluids and cells. occlusive dressing or a hydrogel is applie over the wound and left while wound exudates. MECHANICAL DEBBRIDEMENT uses mechanical force. it is nonselective as it removes healthy granulating tissue also. Wet to Dry dressing wound bed is filled with saline moistured gauze, allowed to dry over several hours then remove along with intact necrotic tissue, can be painful.
plasmapherasis
removal of whole blood from the body, separation of its cellular elements by centrifugation, and reinfusion of them suspended in saline or some other plasma substitute, thereby depleting the body's own plasma without depleting its cells
diagnosis
risk for impaired skin integrity r/t immobility, poor nutrition, age, incontenence. impaired skin integrity r/t immobility, poor nutrition, age incontenence AEB a 3cmx4cm stage II sacral pressure ulcer impaired tissue integrity R/T infected surgical wound, diabetes, steroids, poor nutrition AEB large abdominal dihiscence.

viral infections
warts,
abrasian
wound in which skin or mucus membrane are rubbed or scraped away
fistula
Abnormal tubelike passage between organs or between an organ and the body surface, often as the result of poor wound healing
allergic reactions in the skin
Allergic reactions and skin inflammation are responses to injury mediated by histamine release. External or internal irritants can cause the reactions. The irritants may be chemical (e.g., skin creams, latex gloves, detergents, plants such as poison ivy or poison oak) or mechanical (e.g., rubbing against an irritant, such as wool). Foods and medications also may cause skin reactions. Dermatitis, an inflammation of the skin, most often produces epidermal and dermal damage or irritation, possibly accompanied by pain, itching, redness, and blisters. Chronic dermatitis produces changes in the epidermis, including thickening, scaling, and increased pigmentation. Treatment focuses on eliminating exposure to the allergen and may include lubrication of the skin and application of topical medications
sclerosis
An area of skin indurated (hardened) from collagen deposits in the cutaneous and subcutaneous tissue as a result of chronic inflammation is termed sclerosis. Examples include keloid formation, stasis dermatitis, and scleroderma.
Types of major wound healing are classified as primary and secondary and tertiary
PRIMARY INTENTION wounds with minimal tissue loss, clean surgical incision, shallow sutured wound, the edges are approximated, (lightly pulled together), granulated tissue is not visible, minimal scarring. surgical wounds heal by primary intention. SECONDARY INTENTION wounds have full thickness tissue loss, deep laceration, burn, pressure ulcers, they have edges that don't readily approximate. the open wound will fill with granulation tissue, then epithelial cells migrate over base, more scarring. TERTIARY INTENTION occurs when a delay ensues between injury and wound closure. also called delayed primary closure. When a deep wound is not sutured immediately or purposely left open until there is no sign of infection. or maybe they had a wound and didn't go to hospital and now it needs debridement.
drainage
THE PENROSE A HEMOVAC THE JACKSON-PRATT. THE PENROSE: drain is a hollow fat rubber tube places directly into the incision or into a stab wound in the incitional area. it allows fluid to drain through capillary action into absorbant dressing. HEMOVAC placed into a vascular cavity where blood drainage is expected after surgery. suction is maintained by compressing a springlike device. when inspecting it expect bloody drainage and ensure that it remains in the compressed state. suction can be interupted if leaks are present in the system or if the hemovac has filled with drainage. JACKSON-PRATT permits drainage to collect in a bulblike device that can be compressed to create gentle suction.
zosteriform

types of drains
NPWT NEGATIVE PRESSURE WOUND THERAPY also called a WOUND VAC NPWT is a method that uses specialized gauze or sponge dressings to fill a wound cavity, is covered by a transparent dressing, and then is connected to tubing and a machine that provides negative pressure to the wound. NPWT reduces excess moisture in the wound, reducing the bioburden (the number of microorganisms) and associated toxins •The Penrose drain is a hollow, fat rubber tube placed directly into the incision or into a stab wound in the incisional area. It allows fluid to drain through capillary action into absorbent dressings. Penrose drains may be advanced or shortened to drain different areas. •A Hemovac is placed into a vascular cavity where blood drainage is expected after surgery. Suction is maintained by compressing a springlike device. When inspecting a Hemovac drain, expect bloody drainage and ensure that it remains in the compressed state. Suction can be interrupted if leaks are present in the system or if the Hemovac has filled with drainage. •The Jackson-Pratt drain permits drainage to collect in a bulblike device that can be compressed to create gentle suction. Suction is lost when the bulb is expanded because of too much drainage or a leak in the system. With any drainage system, inspect the system to ensure that it is patent and functioning. Drains may or may not be sutured in place, so take care not to inadvertently remove them during inspection. Nurses promote optimal wound healing by ensuring that closed drainage systems function properly and by selecting dressings that adequately absorb wound drainage. For large amounts of drainage, the nurse may utilize collection devices, wound drainage management systems, or pouching to contain the drainage and protect the skin. Nurses also protect skin from irritation by protecting surrounding skin from caustic drainage or constant moisture. Drainage in an open drain occurs passively by gravity and capillary action, which is the movement of a liquid at the point of contact with a solid, which in this case is the gauze dressing. Open drains are flat, flexible tubes that provide a pathway for drainage toward the dressing. Closed drains are more efficient than open drains because they pull fluid by creating a vacuum or negative pressure. This is done by opening the vent on the receptacle, squeezing the drainage collection chamber, and then capping the vent
negative pressure wound therapy
NPWT= negative pressure wound therapy, also called a vacuum assisted closure= VAC it is a method that uses special gauze to fill a wound cavity, it is covered by a transparent dressing, and then it is connected to tubing and a machine that provides negative presssure to the wound. it reduces excessive moisture, reduces bioburden (the number of microorgansims). and toxins. it increases cell proliferation and perfusion in the wound. it speeds up tissue healing.
