Wоund Cаre The fоllоwing informаtion wаs obtained from the Nursing 2020 journal - https://journals.lww.com/nursing/Fulltext/2019/10000/Wound_Care_101.10.aspx. Successful wound management starts with a thorough assessment of the wound and periwound skin. The assessment should include the following components. Anatomic location. Location can provide information regarding possible causes of the wound. For example, a wound over the sacral area in a bed bound or immobile patient could be a pressure injury, a wound in a lower extremity with accompanying edema could be a venous ulcer, and a wound on the plantar surface of the foot may be a neuropathic ulcer. Degree of tissue damage. Determining the degree of tissue damage in a wound will help to guide the care plan and will provide some information regarding the healing trajectory. Wounds can be described as partial thickness, with damage limited to the epidermal and/or dermal layers, or full thickness with damage evident in the subcutaneous layers and below (see Skin anatomy). For pressure injuries, the staging classification defined by the National Pressure Ulcer Advisory Panel (NPUAP) is used to describe the appearance of the wound and the extent of tissue damage. Type of tissue in the wound. Tissue in the wound bed can be described as viable or nonviable. Viable tissue can appear beefy red as with granulation tissue, or light pink in the case of new epithelial tissue. In contrast, the appearance nonviable or necrotic tissue varies: Eschar may be black, brown, or tan; fibrin slough is described as stringy or adherent and yellow in color. Wound size. Describe the size of a wound according to linear dimensions (length times width). Measure a wound's length using the head-toe axis; measure its width from side to side. If the wound has depth, measure from the deepest point of the wound to the wound surface using a sterile cotton-tip applicator. Assess for sinus tracts (sometimes called tunneling), which can occur in full-thickness wounds. This dead space has the potential for abscess formation. The depth of a sinus tract can be measured by gently probing the area with a sterile cotton-tip applicator. The distance from the visible wound base to the end of the tract indicates the tract's depth. Identify and measure the location of sinus tracts using the analogy of a clock face, with 12:00 pointing toward the patient's head. Undermining is tissue destruction at the edge of the wound, creating a liplike effect. This can also be measured by gently probing the area with a sterile cotton-tip applicator and recording the location using the clock face analogy. Wound edges and periwound skin. The outer edge of the wound can provide information regarding how long a wound has been present and may even assist in determining the etiology. Wounds over bony prominences with defined edges may be related to pressure. Venous wounds found on the leg are characterized by an irregular shape and undefined edges. Infection. Note the presence or absence of signs and symptoms of local infection (erythema, induration, pain, edema, purulent exudate, wound odor) during the wound assessment. Keep in mind that patients with chronic wounds may not exhibit these classic signs and symptoms of infection due to the presence of biofilm. This extracellular polysaccharide matrix embeds microorganisms, delays healing, and renders infection difficult to diagnose. Pain. The presence and intensity of pain associated with the wound can provide some important information regarding wound etiology and wound chronicity. However, the degree of pain may not correlate to the extent of injury. Skin tears, for example, can be very painful because damage confined to superficial skin can expose nerve endings in the dermal layer. Conversely, patients with neuropathic ulcers on the plantar aspect of the foot and concomitant peripheral neuropathy may feel little or no pain, even if the wound is grossly infected. A patient with type 2 diabetes presents with the following wound. How would you classify the wound?
Micrоbiоtа (Cоntinued) The following informаtion wаs acquired from - https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3535073/. Molecular approaches examining bacterial diversity have underlined the concept that the skin microbiota is dependent on the body site and that caution should be taken when selecting and comparing sites for skin microbiota studies. Researchers have demonstrated that colonization of bacteria is dependent on the physiology of the skin site, with specific bacteria being associated with moist, dry and sebaceous microenvironments. In general, bacterial diversity seems to be lowest in sebaceous sites, suggesting that there is selection for specific subsets of organisms that can tolerate conditions in these areas. Sebaceous sites that contain low phylotype (an environmental DNA sequence or group of sequences sharing more than an arbitrarily chosen level of similarity of a particular gene marker) richness include the forehead (six phylotypes), the retroauricular crease (behind the ear) (15 phylotypes), the back (17 phylotypes) and the alar crease (side of the nostril) (18 phylotypes). Propionibacterium spp. are the dominant organisms in these and other sebaceous areas, which confirms classical microbiological studies that describe Propionibacterium spp. as lipophilic residents of the pilosebaceous unit. Metagenomic analysis has revealed that Staphylococcus and Corynebacterium spp. are the most abundant organisms colonizing moist areas, consistent with culture data suggesting that these organisms prefer areas of high humidity. These moist sites include the umbilicus (navel), the axillary vault, the inguinal crease (side of the groin), the gluteal crease (topmost part of the fold between the buttocks), the sole of the foot, the popliteal fossa (behind the knee) and the antecubital fossa (inner elbow). Staphylococci occupy an aerobic niche on the skin and probably use the urea present in sweat as a nitrogen source. The most diverse skin sites are the dry areas, with mixed representation from the phyla Actinobacteria, Proteobacteria, Firmicutes and Bacteriodetes. These sites include the forearm, buttock and various parts of the hand. Take a look at the picture below showing the diversity of phylotypes on different regions of the skin. Which skin regions contain the highest phylotype diversity?
Micrоbiоtа In heаlthy humаns, the internal оrgans and tissues such as muscles, the brain, and blood do not contain microorganisms. However, surface tissues, such as the skin and mucous membranes, are in continuous contact with environmental microbes and become readily colonized by specific bacteria. The population of microbes regularly found in the body is referred to as the normal microbiota. The term transient microbiota refers to members of the normal microbiota that are present for only a short time before disappearing. A person’s normal microbiota is an important part of the immune system, as the normal microbiota often inhibit pathogenic microbes from colonizing the host, a process called microbial antagonism. Different types of bacteria will colonize different niches in a person’s body due to variations in moisture level, pH, atmospheric pressure, oxygen levels, and body secretions. Accordingly, different types of media must be used to culture the various human microbiota. If normal microbiota organisms are only found to colonize a human's skin for a short period of time, they are referred to as ___________.
MRSA The fоllоwing infоrmаtion wаs аcquired from - https://www.ncbi.nlm.nih.gov/books/NBK396238/#:~:text=MRSA%20typically%20is%20classified%20as,procedure%20during%20a%20hospital%20stay.. Methicillin-resistant Staphylococcus aureas (MRSA) is a bacterium that is resistant to many of the most commonly prescribed beta-lactam antibiotics, including penicillin, amoxycillin, oxacillin, and methicillin. Severe cases of MRSA may result in endocarditis, osteomyelitis, septicemia, or even death. Each year MRSA accounts for approximately 11,000 deaths in the United States. Costs associated with a MRSA infection are high, with an average hospital length of stay of 10 days and average hospital costs of $14,000. The average length of stay and hospital costs associated with MRSA are approximately 2 times higher than those of other hospital stays. MRSA typically is classified as hospital acquired; health care acquired, community onset; or community acquired, community onset. Hospital-acquired MRSA usually is the result of a nosocomial infection, often acquired following a surgical or invasive medical procedure during a hospital stay. Health care-acquired MRSA develops outside the hospital while the patient is in the community and has had recent contact or received treatment in a health care facility, such as an inpatient hospital, ambulatory surgical center, dialysis center, or nursing facility. Community-acquired MRSA occurs among community-dwelling individuals without recent hospitalization or encounters with the health care system. Because the following video shows the drainage of MRSA wounds, please only watch if you are not squeamish. The question does not require you to watch the video. MRSA, MRSA, MRSA, MRSA, MRSA and MRSA! If a nursing home patient acquires an MRSA infection, what type of transmission would describe this situation?
Wоund Cаre (Cоntinued) Once the wоund is аssessed аnd the etiology of the wound has been determined, the nurse can initiate topical therapy. Topical dressings create an environment that fosters the normal healing process. The following eight objectives should be considered when selecting the most appropriate interventions. 1. Prevent and manage infection. One of the primary goals of topical wound care is to protect the wound base from outside contaminants such as bacteria. If infection is evident in the wound, wound cultures should be considered and the need for topical antimicrobial/antiseptic products should be discussed with the primary provider. Topical antibiotics destroy microorganisms; topical antiseptics inhibit microbial growth. Examples include cadexomer iodine, honey, silver sulfadiazine, and topical antibiotics. These products, which are covered with a secondary dressing, can be used in partial-thickness and full-thickness wounds that are infected or at high risk for infection. They should not be used long-term. 2. Cleanse the wound. Routine cleansing should be performed at each dressing change with products that are physiologically compatible with wound tissue. Normal saline is the least cytotoxic; when delivered at a pressure of 4 to 15 PSI, it is adequate to remove wound debris. Commercially available wound cleansers can also be used, but avoid hypochlorite solutions, betadine, hydrogen peroxide, and acetic acid in routine wound cleansing as these agents can be cytotoxic to fibroblasts. 3. Debride the wound. If necrotic tissue is visible in the wound bed, removal of this devitalized tissue is indicated in most circumstances. One exception to this is stable, dry eschar on the heel. In this circumstance, leaving the eschar in place is recommended until the patient's vascular status can be determined. Wound debridement can be accomplished with several different methods. Autolytic debridement, the slowest form of debridement, is accomplished through use of moist topical dressings that foster autolysis of necrotic tissue. Enzymatic debridement is accomplished by applying the prescribed topical agent directly to the wound bed. It is usually applied daily and covered with a dressing such as gauze, moistened gauze, or foam. Sharp wound debridement may be performed at the bedside (conservative wound debridement) or in the OR (surgical wound debridement) by a qualified healthcare provider. Wounds that are necrotic and showing signs of infection should be treated with sharp/surgical debridement as soon as feasible. 4. Maintain appropriate moisture in the wound. A moist wound environment has been shown to facilitate wound healing, reduce pain, and decrease wound infection. In wounds that are heavily draining, the nurse should apply the type of dressings that will help absorb excess drainage so that an appropriate level of moisture can be maintained in the wound bed. 5. Eliminate dead space. Wounds that have depth need to be packed. Packing agents, such as normal saline and hydrogel-impregnated dressings, can keep the wound bed moist. In wounds that are too moist, alginate or hydrofiber dressings can help control excess drainage. Packing material should be easy to remove from the wound base during each dressing change to avoid injuring healing tissue. 6. Control odor. To manage odor, if present, the nurse should consult with the provider about the frequency of dressing changes, wound cleansing protocol, and the possible need for debridement or topical antimicrobials. The primary healthcare provider or wound care specialist should be consulted regarding treatment options to control wound odor. 7. Manage wound pain. Wounds that are painful should be thoroughly assessed for the presence of infection or other etiology (such as an associated fracture or a foreign object in the wound) and treated accordingly. The use of moisture-retentive dressings can help to decrease pain associated with dressing removal and can also decrease the need for frequent dressing changes in painful wounds. 8. Protect periwound skin. Heavily draining wounds or the improper use of a moist dressing can lead to maceration of the periwound skin, altering tissue tolerance and damaging the wound edges. Skin barrier creams/ointments, skin protective wipes, or skin barrier wafers can be used to protect the periwound skin. The selection of an appropriate topical dressing should be guided by the objectives described above. Always follow the manufacturer's guidelines in addition to your facility's policies and procedures for specific use of these products. If a patient has a dry wound, which type of dressing would be best to use to make sure the wound environment stays moist for optimal healing and can be soothing for a painful wound?
