Abstract Although many types of wounds are easily treated, some require specialized expertise in order to resolve or treat the primary cause and to prevent additional wounds. Clinicians who opt to specialize in wound care provide an important skillset to patients suffering from chronic or acute injury, disease, or medical treatment. Often, a holistic approach is adopted, with coordination of health team efforts to ensure that all aspects of a patient's health are considered during the course of initial and ongoing wound care management. Wound care clinicians also serve as a resource to prepare the patient to continue care at home. nursece4less.com nursece4less.com nursece4less.com nursece4less.com 1

Introduction In some situations, wounds are slow to heal, stalled, or are considered hard to heal when they take months or years to be fully restored. Alternatively, some wounds respond to standard treatments and heal without complications. Regardless of the situation in which a wound has developed, the factors surrounding the cause, course of treatment, and potential complications of the wound must all be weighed closely as part of wound management. While clinicians who care for patients with wounds typically address the physical factors required for wound care: the appropriate dressings and medical treatments to use, as well as the patient s medical background, a holistic approach should be incorporated instead that comprehensively addresses factors that contribute to the delayed healing. Holistic Approaches There are several factors that must be considered as part of holistic healing of wound care. Patient-related factors, aspects of the wound, and the skills and knowledge of the clinician all impact not only how the wound will heal, but should also be included as a regular part of assessment and management of the wound. For instance, a patient who has altered coping mechanisms for managing anxiety related to wound treatments may have a difficult time undergoing treatments. The patient s ability to endure wound treatments and his or her ability to cope with anxiety about the treatments should be assessed at each wound care encounter. A position document developed by the European Wound Management Association discussed the factors to include as part of the comprehensive and holistic wound care assessment that are related to the patient s background and these include physical diseases and medical conditions, such nursece4less.com nursece4less.com nursece4less.com nursece4less.com 5
as diabetes, obesity, or lupus; additionally, psychosocial factors, including gender, economic status, and a history of mental illness and other patientrelated aspects that may affect management of the situation, including the patient s spiritual background, beliefs, cultural practices, and coping mechanisms were included. 52 Factors associated with the wound that must be considered have been discussed throughout prior courses in this series, and include such elements as the size, depth, or stage of the wound, the presence of infection, the development of granulation tissue and the condition of the wound bed, whether inflammation is present, the location of the wound on the body, and how well the wound is responding to treatment. Finally, the characteristics of the healthcare clinician who manages the wound must be considered in terms of skill sets and a firm knowledge base on which to support practice parameters. The clinician factors to consider with wound management include knowledge of current and appropriate wound treatment techniques, continuing education practices, certification in certain areas related to skin and wound care, and the background knowledge of the process of wound healing. 52 All of these factors form a base of assessment that includes a holistic approach to wound healing. When these factors continue to be assessed and addressed during treatment sessions and encounters with the patient, the clinician is working toward a comprehensive approach to wound care. Because a wound may take a significant amount of time to heal, the wound patient may be in a state where he or she is able to provide self-care at home, or resides in a long-term care environment. Either location may not provide the continuous nursing support needed for managing health while the body heals from a wound. Therefore, it is important to provide education nursece4less.com nursece4less.com nursece4less.com nursece4less.com 6
and guidance about various factors that will impact wound healing that the patient will need to perform on his or her own and to check in with the healthcare clinician on an ongoing basis. Medication Management and Patient Education Management of the medications administered to the wound patient, discussed in Part III of this series, involves not only an understanding of the indications, dose, and routes of administration of the drug, but it also means educating the wound care patient about the specific information needed to know about the medication. The patient who takes medication or who uses such items as dressings that are infused with medications must have a thorough understanding of the reasons for and potential outcomes of the medication. A better understanding of the purposes of medication on the part of the patient may more likely increase compliance with wound care. Some patients want to pursue their own measures for healing or controlling the health of their wounds. They may take medications or apply topical ointments to the wound as a method of treating the wound, which may or may not work in conjunction with the medical care the clinician is providing. For example, a patient may believe that hydrogen peroxide should be applied to a wound every day to prevent infection even though regular dressing changes are being done. When discussing medications used for wound healing, the clinician may also need to discuss what measures the patient should avoid, as certain agents can cause more damage to the wound and surrounding tissue. A patient who is at home with a wound should be educated about the medications needed for wound care and treatment, which may include topical ointments and/or systemic antimicrobial drugs. Education about nursece4less.com nursece4less.com nursece4less.com nursece4less.com 7
medications in this case is similar to teaching a patient about taking any type of medication; to follow the orders of the prescription and take the medication as prescribed. If the patient will be responsible for applying a topical ointment to the wound, the clinician may have the patient demonstrate the proper method for applying the medicine before being expected to do it independently. Finally, as with other forms of medication teaching, education about the medications associated with wound care measures must cover what side effects or interactions require further contact with the health clinician. The clinician may need to review the patient s current medications to ensure that they do not interact with the medication the patient will need to treat a wound. The patient should also be taught about common side effects associated with the medication and when to call the health clinician. Nutritional Guidance The process of wound healing, including formation of proteins in skin structure and skin cell proliferation require extra energy that typically must be taken in through nutrients in food and dietary supplements. The malnourished patient, in particular, needs extra energy in the form of calories, protein, and vitamins, to facilitate the wound healing process when he or she cannot pull nutrients from energy sources in the body. Alternatively, even the patient who is considered relatively healthy and was not malnourished prior to wound development should still have ample energy intake to support wound healing and prevent delays. The clinician must provide education to the patient about the importance of nutrition related to wound care; teaching should include information about how wounds can be more likely to develop in the absence of adequate nursece4less.com nursece4less.com nursece4less.com nursece4less.com 8
vitamins and nutrients. Teaching should also focus on what nutrients the patient should take on a daily basis and how much of each the patient should strive for, with examples provided of types of foods and preparation methods available. It may be helpful to have the patient speak with a registered dietitian or nutritionist for further ideas about how best to gain enough nutrients for wound healing. The Joint Commission has emphasized the requirements of screening and assessment for patients who are at high risk of malnutrition and to follow up on these assessments with routine evaluations to determine effectiveness of interventions. 20 This practice is particularly important for patients who are malnourished and who have developed wounds; however, even high-risk patients who have background factors that could lead to malnutrition should be routinely assessed for their nutritional intake and its effects on wound healing. The clinician may need to measure the patient s height and weight and calculate the body mass index (BMI). As stated, even a person who is obese can suffer from malnutrition, so the outcome of the BMI does not necessarily reflect specific nutrient intake or lack thereof. However, the BMI results do provide a starting point for the clinician to discuss the importance of nutrition and of maintaining a healthy weight, as well as what should be considered if the patient needs to gain or lose weight. Discussion of the BMI also provides a setting in which the clinician can talk about intake of certain foods and learn more about the patient s overall caloric intake as well as intake of other important nutrients, such as protein. According to Wild, et al., in the journal Nutrition, the average intake of a healthy person is between 30 and 35 kcal/kg body weight per day, which is nursece4less.com nursece4less.com nursece4less.com nursece4less.com 9
dependent on the amount of activity the person engages in. When other health factors are present that contribute to wound development, such as advancing age, a history of chronic illness, or malnutrition, the patient needs more energy intake each day to promote wound healing and should strive for 35 to 40 kcal/kg each day. 53 The patient should be provided with information about the nutrients that are important for wound healing, why they are needed, and how they can get them into the diet. Protein is a macronutrient that is essential to wound healing because of its role in building collagen, which provides a structural framework of the healing skin tissue. Proteins also make up the backbones of many cells of the immune system, including macrophages, lymphocytes, monocytes, and leukocytes. Normal protein requirements are approximately 1.5 g/kg of body weight per day; more protein may be necessary if the patient is malnourished or has a significant wound, such as a burn wound. 20 In some cases, supplementation with formula preparations is beneficial and can add calories and protein to the diet of a patient who has difficulty taking in enough nutrients on a daily basis. Protein supplements, such as liquid nutritional shakes, can be purchased over the counter or may be available by prescription. The health clinician should first determine the amount of protein and other nutrients needed in the patient s diet before advising the patient to purchase protein shakes. However, with proper guidance, some brands of nutritional supplements can be very helpful in supporting nutrition for the wound care patient. While lipids and carbohydrates are important components of the diet because they provide energy for the patient, such intake should be nursece4less.com nursece4less.com nursece4less.com nursece4less.com 10
monitored carefully and the patient should be given instructions about how much to take in of each of these elements to avoid overfeeding. Chronically elevated glucose levels in the bloodstream can lead to changes in the cardiovascular system and can alter the body s immune defenses. Further, excess intake of fatty foods can cause hypertriglyceridemia and can impact liver function. 20 These elements should be carefully reviewed with the wound care patient, and the clinician should determine the patient s normal intake while also preparing guidelines for how much the patient should be consuming of these nutrients. The amount needed and the amount the patient normally eats may not be the same. This is the time that the clinician can discuss the effects of excess carbohydrates and lipids in the body, as well as their effects on wound healing, and how to take in proper amounts of these nutrients to support good health. As stated, vitamin C is important to protect the immune system and to support collagen synthesis in the wound bed. The patient should be encouraged to increase intake of vitamin C in the diet. This is done by consuming more fruits and vegetables, including citrus fruits, such as oranges and grapefruit, as well as other fruits and vegetables, including strawberries, tomatoes, broccoli, and cantaloupe. Vitamin A may be added to the diet to increase wound strength as the wound is healing. The patient can be taught about the benefits of vitamin A, as well as how best to get this fat-soluble vitamin into the daily diet. Vitamin A may be taken in through supplements or the patient can consume foods such as sweet potatoes, carrots, and dark green, leafy vegetables. Vitamin E deficiency causes negative effects in the body because vitamin E has anti-inflammatory properties that can control inflammation in and nursece4less.com nursece4less.com nursece4less.com nursece4less.com 11
around the wound. Vitamin E is also an antioxidant and has been used in topical preparations for skin care. A true vitamin E deficiency is uncommon, partly because it can be easily supplemented into the diet through vitamin preparations or foods. 20 Vitamin E can be found in foods such as almonds and peanuts, green, leafy vegetables, including broccoli and spinach, and vegetable oils, such as corn, sunflower, and soybean oils. McCullogh and Kloth, in the book Wound Healing: Evidence-Based Management, state that two other micronutrients, zinc and iron, are important for maintaining health when a patient is healing from a chronic wound. Deficiencies of zinc in the diet can cause decreased fibroblast production in the wound bed, decreased epithelialization during healing, and an increased risk of infection. Iron is needed for heme molecules in the red blood cells to support oxygenation of the tissues and it is necessary for collagen production. 20,53 Deficiencies in both of these trace elements can lead to serious deficits in wound healing and may more likely be seen in patients who suffer from chronic illnesses such as alcoholism, iron-deficiency anemia, and gastrointestinal disorders. Patients can increase intake of zinc by increasing intake of lean beef and turkey; or, seeds, such as sunflower seeds or pumpkin seeds, or by eating beans and lentils. Iron is also found in red meat, poultry, and beans, as well as eggs, dried fruits, and iron-fortified cereals. A patient who is already malnourished will need an assessment of his or her overall health and ability to get enough nutrients through the diet. Such factors for assessment include any situation that prevents the patient from taking in, digesting, and absorbing nutrients. If there are physical abnormalities that are causing malnutrition, these items must be addressed nursece4less.com nursece4less.com nursece4less.com nursece4less.com 12
as part of wound care treatment, or the clinician can expect delays in wound healing. Alternatively, a patient may have a wound that is being managed but may not be malnourished. In this case, the patient must still be taught about the importance of nutrition and diet, but supplementation may not be necessary. The clinician may order enteral nutrition or supplementation for a patient who is malnourished, but for someone who does not have difficulties with getting enough nutrients, diet and fluid intake should provide adequate nourishment. If the health clinician decides to order supplements of specific vitamins or nutrients to support certain aspects of wound healing, this may be based on the client s condition, the progress of wound healing, and other individual health factors. Emotional Support Much of the wound care provided by the clinician will focus on the physical aspects of wound treatment; the size of the wound and how well it is healing, the use of the right kind of dressing or debridement practices, and whether or not other factors, such as infection or malnutrition are present. Although all of these measures are very important components of wound care and treatment, the emotional health and wellbeing of the patient must also be considered as a primary factor in the promotion of wound healing and prevention of complications. While a medical or nursing clinician may be very focused on treatment regimens and techniques required for wound healing, the patient is often more focused on how the wound impacts his or her life. For example, although a clinician may decide to utilize a new type of dressing to promote wound healing, the patient may be more concerned with the appearance of nursece4less.com nursece4less.com nursece4less.com nursece4less.com 13
the dressing or its bulk that appears underneath clothing. Although the physical aspects of wound healing may be important, the clinician must address psychosocial factors in order to provide holistic care to the patient and to better ensure that the patient will be a willing partner to work toward wound healing. Wounds International developed an expert working group that discussed wound care healing and the wellbeing of patients. The group had defined wellbeing as: a dynamic mix of factors, including physical, social, psychological, and spiritual.the ultimate goals [of wound healing] are to optimize well being, improve or heal the wound, alleviate/manage symptoms and ensure all parties are fully engaged in the process. 54 The process of supporting the patient s wellbeing involves considering all aspects of patient care, to include the patient s physical needs for wound care, pain control, and management of chronic diseases, as well as supporting the patient s emotional, spiritual, and psychosocial health, as these components are tied into holistic wound care. A patient with a wound may suffer from a multitude of emotions related to the cause of the wound or injury, the appearance and healing process of the wound, or how the wound affects the body. A person who has suffered an extensive wound may have disfigurement in addition to the pain and discomfort associated with wound care practices. He or she may struggle with grief in accepting how the body has changed as a result of the wound. A wound may cause psychological stress for a patient in other ways as well; having a wound may also make a person feel sad or ashamed because of the nursece4less.com nursece4less.com nursece4less.com nursece4less.com 14
condition, and the patient may feel like a burden to others who are responsible for caring for them. The physical discomforts of a wound also cause psychological stress for the affected patient. A patient with a wound may struggle with feelings of loneliness and isolation, particularly when the wound affects the patient s mobility. The patient may be embarrassed about the appearance of the wound; a wound that has an odor may be very embarrassing and may lead the patient to avoid being around others. The clinician who provides comprehensive wound care in a holistic manner must address these and other psychological concerns affecting the patient. Needs may change over time, particularly if the wound takes many months to heal. For example, a wound that once affected a patient s mobility by limiting an ability to walk may have healed enough that walking is no longer an issue. However, with time, the patient may have started to feel more anxiety about potential job loss because of the time away from work to care for the wound. Each assessment should have some component that checks the patient s emotional wellbeing. If the patient is able to express feelings related to wound health, the clinician should be able to respond with resources to help the patient through his or her feelings, whether it is done during clinical encounters or a referral to another professional, such as a psychological counselor. The clinician can come up with many practical solutions to help a patient through anticipated difficult emotions that accompany a wound. Wound care measures have changed from large, bulky dressings to those that are more likely to be low profile; the clinician may help the patient with fears about the appearance of a wound with finding wound care items or articles of nursece4less.com nursece4less.com nursece4less.com nursece4less.com 15
clothing that minimize the wound instead of drawing attention to it. When odor is present, the clinician can investigate the possible source and need for an antibiotic prescription if the odor is caused by infection. In other cases, consulting with a wound care expert, such as an advanced practice nurse or certified wound, ostomy and continence nurse, provides needed support to determine the type of dressings or wound management regimen needed to control wound odor, and providing patient comfort. Some patients who suffer from anxiety or depression may have more difficulties accepting a wound and/or working with wound care professionals for wound management. The patient who has a diagnosed mental health condition as well as a chronic wound will need continuous clinical support for management of such a condition. When a wound first develops, the patient may benefit from added short-term counseling or therapy for help to manage the many emotions associated with the setbacks associated with acute wound care. Other measures that the clinician may consider when providing emotional support for the wound care patients include helping them think about the positive elements of their life, what creates a sense of happiness or hope and optimism for the future. Additionally, the clinician may encourage a patient to come up with alternative activities of enjoyment that can be performed even while undergoing wound treatment, and providing information about support groups available for patients struggling with body image or chronic illness. Additionally, the clinician may provide patients with information about stress management and the signs or symptoms that indicate they may be developing emotional issues related to wound care that need to be addressed. nursece4less.com nursece4less.com nursece4less.com nursece4less.com 16
Above all, the clinician needs to provide compassionate care to the patient that includes discussion of his or her emotional health and assistance with problem solving if the patient identifies difficult feelings associated with wound healing. The clinician provides support by demonstrating competence in wound care measures, respecting the patient s privacy and showing empathy for the patient s feelings. Preparing Patients For Wound Care At Home Patients who are at home while healing from wounds should be taught principles of skin care and wound management as well as what factors or activities to avoid that could lead to wound complications such as infection. A patient with a wound needs to rest to avoid excess stress, which can impair wound healing. He or she should be taught to avoid putting pressure on the wound. For instance, a diabetic client with a foot ulcer on the ball of the foot should not walk or put pressure on the affected foot while the wound is healing. The patient may need to use crutches or a specialized type of shoe instead. When a wound affects an extremity, the patient should rest the area and elevate it on a pillow or blankets. This is particularly important with certain kinds of ulcers and wounds, as rest and elevation can help with venous return of blood to the heart and prevent venous stasis. A patient with a venous ulcer who needs to wear compression stockings should be taught about how the stockings work and their effects on circulation. The clinician should instruct the patient about how to put the stockings on and the patient should be able to demonstrate how to put the stockings on as well. Because the patient will most likely need to wear compression stockings for a long period of time, providing resources to obtain additional pairs of stockings and education will be needed (i.e., how long to wear the stockings and replacing them every 4 to 6 months). The nursece4less.com nursece4less.com nursece4less.com nursece4less.com 17
stockings are typically ordered by prescription and the patient may need support to arrange for additional compression stockings when replacements are needed. Some patients will need to be at home with devices that protect the skin around the wound and that are designed to promote safe healing of a wound. This is more likely the case with an extremity wound; examples include casts, specialized boots or shoes that cover the dressing and the wound and prevent excess pressure on the site. Foam mattress covers placed on the bed to reduce the risks of further damage of pressure ulcers are often recommended. The clinician should review the signs of a developing wound with the patient, and educate the patient to observe for signs of persistent skin redness, areas of skin becoming soft or spongy, pain or symptoms of poor circulation in the lower legs, particularly while walking, and numbness, tingling, or loss of sensation in the affected body area. A patient who needs to change a dressing on the wound will need education about the process of the dressing change and the principles of infection control. This education may be provided to the patient as well as to family members who may be helping with dressing changes in the home. The clinician first should review the process of a dressing change with the patient in a step-by-step fashion, and demonstrating how to change the wound dressing. This should be followed with the patient demonstrating to the clinician how they would change the wound dressing, so that any information may be reviewed again. Because of the variety of dressings available that the patient may use, the content of the teaching will vary slightly in terms of when and how to remove the old dressing and the process of applying the new one. However, nursece4less.com nursece4less.com nursece4less.com nursece4less.com 18
several principles apply and should be included as part of teaching, regardless of the type of dressing the patient is using. The clinician should include information about the importance of hand hygiene both before and after caring for the wound, as well as why hand washing prevents the spread of germs and can prevent a wound infection. The patient should also be taught about what to look for as signs of infection in the wound while changing the dressing, including the most common signs, such as redness, odor, purulent drainage, and inflammation or breakdown of the skin surrounding the wound. Further, if these signs or symptoms develop, the clinician must provide contact information and instruct how to be reached by the patient for wound evaluation. The patient may also need help with getting the appropriate supplies to perform dressing changes and wound care at home. If a patient uses a specialty dressing for wound care, the clinician may need to work with a wound care specialist to help the patient gain access to the appropriate supplies to change the dressing at home. If a patient requires a cast or other mobility products, certain materials may only be accessed through a medical supply company or pharmacy. Medications and ointments may also be provided through the pharmacy. Some patients with significant wounds require a visiting nurse or home health care nurse to make a certain number of visits to the home to check the wound, change dressings, and check on the patient s overall health. It should be noted that a patient who is sent home with a healing wound most likely has a stable wound without significant infection. The patient should also have health care processes in place before being discharged to home. For instance, if a patient has a wound on the outer malleolus of the ankle that requires dressing changes, he or she should understand how to nursece4less.com nursece4less.com nursece4less.com nursece4less.com 19
change the dressings and should have other components set up for wound care, such as a specialized walking boot that will protect the ankle during the healing process. A patient who has an unstable wound that needs more consistent care either needs to be monitored much more closely by a home health nurse or needs inpatient treatment for regular care of not only the wound, but any other underlying components, such as chronic disease management. Wound Prevention While there are many forms of wound care treatments, procedures, and specialized products that can help wounds to heal, the best form of skin care management is to prevent wounds from healing in the first place. Clinical interventions designed to prevent wound development focus on skin protection, management of chronic conditions that contribute to skin breakdown and wound development, and use of methods that will protect the patient from complications. Nursing Interventions Nursing interventions for the wound patient will vary, depending on the patient s background condition and cause of the wound. Some nursing interventions are general and focus on aspects that can lead to skin breakdown in any condition. These interventions include such activities as protecting the skin and mucous membranes, promoting circulation, and assisting with mobility and position changes. Most interventions that are performed to protect the skin will also prevent breakdown. In addition to general interventions for skin protection, there are also specific interventions that focus on preventing wounds from developing because of specific causes. These include interventions aimed at controlling chronic diseases, such as diabetes or venous insufficiency. nursece4less.com nursece4less.com nursece4less.com nursece4less.com 20
Skin Protection Skin protection interventions are performed to keep the skin healthy and intact. On a given day, a patient may encounter various entities that can contribute to skin breakdown, including excess moisture, pressure, poor circulation, or trauma. By reducing or eliminating these factors, the nurse can better protect the patient s skin, provide education to the patient and family members about how best to care for the patient s skin, and prevent skin breakdown that leads to wounds. Because many patients with immobility must spend more time in bed, introduction of a mattress that can protect the skin may be beneficial in certain situations. Some specialty mattresses are designed to prevent pressure ulcers; this type of mattress and bedding may be available in some facilities, particularly in areas where patients are at higher risk of developing these types of wounds. Most mattresses used on beds in hospitals and longterm care facilities can contribute to increased pressure in certain areas and ultimately, to pressure ulcers if the patients who use these beds are not turned or repositioned regularly. 5 The type of mattress to use will depend on the patient s condition, the pressure of skin breakdown and wounds, and whether the patient is able to assist with repositioning or move themself. Some mattress options involve a type of overlay that is placed on top of a standard mattress but that provide a barrier between the patient and the mattress itself, thereby reducing excess pressure on the skin. This type of barrier between the patient and the mattress is relatively low-tech but can provide quality results for patients who are able to shift or reposition while in bed to take weight off areas of the body to avoid pressure wounds. Examples of overlays that act as barriers include sheepskin covers, conformable foam mattress covers, and water- or gel-filled mattress covers. 5 nursece4less.com nursece4less.com nursece4less.com nursece4less.com 21
Specialty beds may also be available in some locations; these beds have specialized mattresses that provide protection for wounds and can prevent pressure ulcers. They utilize high-tech equipment above and beyond the standard type of mattress used in most healthcare facilities and are best used for patients who have difficulty repositioning in bed at all or without placing excess pressure on areas of skin breakdown while turning. They are also useful in those situations where patients have wounds that, despite utilizing other interventions, are still not healing well. When caring for a patient with skin breakdown and particularly someone with mobility issues, the nurse should assess whether a specialized mattress on one of these kinds of bed is available if indicated to avoid pressure wounds. Rather than using an overlay that goes between the patient and the standard mattress, a specialty bed contains a mattress specifically designed to promote circulation to the tissues and to prevent moisture buildup. Some beds mechanically turn patients from side to side on a rotating basis, thereby continuously moving and repositioning the patient. These types of beds are useful not only for preventing excess pressure in certain areas from sustained periods of immobility, but they also relieve some of the work of the nursing staff in consistently turning and repositioning the affected patient. However, despite the effectiveness of these types of beds in repositioning patients, the nurse is still responsible for moving or turning the patient when needed and should not completely rely on the bed to perform all of the work. Another type of bed may help to prevent skin breakdown by using a layer of air or water to circulate just under the patient. This consistent circulation moves and shifts the mattress slightly under the patient on a regular basis and continuously changes areas of pressure so that no one area receives too nursece4less.com nursece4less.com nursece4less.com nursece4less.com 22
much pressure for too long. There are also types of beds that have mattresses that work in a manner similar to sequential compression devices used on the legs to prevent blood clots. These beds routinely inflate and then deflate underneath the patient to promote circulation and prevent excess pressure in concentrated areas. 5 Because excess skin moisture can contribute to softening of the skin and maceration, the nurse should provide regular skin care of the high-risk patient to control skin moisture. Excess moisture on the skin surface can also increase the patient s risk of infection, as increased moisture has a dilutional effect on the skin s acidity levels. This changes the skin s ability to control bacterial buildup on the surface and the patient may be more prone to infection. The nurse should carefully consider use of linens with the patient, as standard linens often found in healthcare environments may contribute to increased moisture staying on the skin, even after the patient s skin has recently been cleaned and dried. Wrinkles in the sheets of standard bed linens may also cause skin damage in a high-risk patient; when the patient lies on top of a wrinkled section of a sheet for a prolonged period, the wrinkled area also contributes to increased pressure. 4 The nurse must routinely monitor the areas of wrinkles or bunching in the linen and strive to keep sheets and blankets straight and flat, particularly in the bottom sheets that lie just on top of the mattress and underneath the patient. Sheets and linens must be further considered when turning or moving a patient in bed, as friction contributes to skin breakdown if the patient is moved up in bed or slides down in bed against the material of the linens. Certain areas that have bony prominences must also be protected against nursece4less.com nursece4less.com nursece4less.com nursece4less.com 23
bed sheets and friction or shear forces. For example, the heels are areas where skin breakdown can routinely develop, as they often lie directly on the bed and the blood vessels supplying oxygenated blood may be compressed under pressure. Heels should be lifted and supported so that they do not rest directly on the mattress surface for long periods of time. Further, when moving a patient in bed, the nurse must consider the effects of bony prominences, such as the heels, when the patient is moved. When moving a patient up in bed without careful protection for the heels, the heels may drag along the surface of the bed while changing the patient s position. This may happen even when the nurse works to protect other areas of the patient s body against the forces of friction and shear. When caring for a patient who uses multiple medical devices, such as in an Intensive Care Unit, the nurse should consider the effects of equipment on the patient s skin and its contribution to wound development. For example, an endotracheal tube that has not been positioned properly can apply pressure to the corner of the mouth or to an area of the lip, thereby causing skin breakdown from tissue ischemia underneath the tube. Further, frequent skin care to remove excess secretions from tubes also helps to keep the skin clean and dry. Alternatively, when a patient has secretions from tracheostomy or endotracheal tubes or leakage around other types of tubing, such as an intravenous or gastrostomy tube, maceration and skin breakdown are more prone to occur in those areas. Incontinence Preventing excess moisture that can cause skin breakdown is also essential when caring for patients who suffer from incontinence. Allowing urine or stool to remain on the skin, even for a short period of time, can lead to skin maceration and wound development. The nurse may apply barrier creams to nursece4less.com nursece4less.com nursece4less.com nursece4less.com 24
the patient s skin that act as a protective layer between the skin and the urine or stool, preventing waste secretions from contacting and breaking down the skin tissue. According to the book Wound Healing: Evidence-Based Management, the best method of cleansing and protecting the skin from breakdown as a result of incontinence is to provide regular hygienic care for the patient by cleaning after episodes of incontinence. The nurse should use a system that not only cleans the patient but that also protects the skin. The ideal product, which may often be available in health facilities where there are patients at risk of skin breakdown, includes a cleanser with qualities to easily lift and clear away dirt and debris from the patient s skin, as well as moisturize the skin to maintain adequate hydration. It should be noted that skin cleansers used to clean a patient who has been incontinent should not be used as wound cleansers. These items do not contain the same ingredients to be used in both situations, and standard skin cleansers used for incontinence could cause cell damage and further skin breakdown when in contact with a wound. 20 The final intervention in preventing incontinence-related skin breakdown is the application of a barrier to prevent future wastes from incontinence from repeatedly contacting the skin. 6 Liquid skin protectants, sometimes referred to as skin sealants, contain a combination of additives that adhere to the skin when the liquid dissolves. The protectant is applied to the skin and, after it dries, provides a thin barrier against collection of debris or waste products on the skin that can lead to skin breakdown. nursece4less.com nursece4less.com nursece4less.com nursece4less.com 25
Moisturizing lotions may be used on areas of dry skin to preserve moisture levels and prevent cracks in the skin, which can increase the risk of infection. Regular bathing and hygiene practices are also necessary to preserve skin function and are a necessary component of nursing care that promotes self-esteem, confidence, and a sense of self-worth. The nurse can help the patient to bathe using warm water and mild soap, following the bath with a moisturizer, if needed. While assisting the patient with bathing, the nurse should inspect the skin for areas of redness, areas that seem to be at higher risk of skin breakdown and, simultaneously for wounds that have already developed. Repositioning The National Pressure Ulcer Advisory Panel (NPUAP) has given guidelines for how often a nurse should assist a patient with repositioning in order to effectively prevent skin breakdown from excessive pressure. A patient who is confined to bed should be repositioned and turned while in bed at a minimum of every two hours. A patient who is sitting in a chair should be repositioned and assisted to shift body weight on the seat at least every one hour. A patient who is sitting in a chair should not sit on an inflatable donut pillow, as these types of devices place excess pressure on bony prominences and areas where the patient sits. When turning or repositioning a patient, the nurse should take measures to avoid applying extra forces against the patient s skin that contribute to injury and skin breakdown. Friction against the skin occurs when the surface of the skin is dragged across another surface. Friction may occur when a patient slides down in bed because the head of the bed has been raised to a high level. The force of friction can cause an abrasion on the surface of the nursece4less.com nursece4less.com nursece4less.com nursece4less.com 26
skin, with the potential to introduce pathogens into a break in the skin surface, as well as further skin breakdown and a larger wound. Shear is another type of force that can lead to skin breakdown; it describes the parallel force of the upper layers of the skin moving away from the lower layers, in which there is a break in the skin structure and damage to the elements found in the skin. For example, a patient may have excess moisture on the skin surface that has not been cleaned or dried off before the patient is moved in bed or repositioned. As the nurse moves the patient, for example, pulling the patient up in bed, the skin surface may slide easily during being pulled up in bed because of the external layer of moisture while the underlying skin tissue remains static or sluggish, causing shear forces to occur. With shear forces, the layers of skin move on a parallel plane but at different paces or in opposite directions from each other, thereby disrupting the connections between skin layers and causing injury. Shear is often associated with friction and the two forces may occur at the same time. Shear results in damage to structures found in the dermal layer; the blood vessels may be stretched with the force and then rupture and bleed into the skin. This damage also decreases blood flow to surrounding tissues, further perpetuating ischemia and promoting skin breakdown. 7 Shear forces may often cause deep tissue injuries, as described above. The nurse must make sure to protect bony prominences for the patient who is immobile and/or who cannot lift up or reposition areas that are prone to skin breakdown. Various cushions and positioning devices are available for parts of the body that may be prone to skin breakdown, such as elbow guards to protect the elbows or cushioned boots to protect the heels. Although moisturizing dry skin is recommended to keep skin moist and to nursece4less.com nursece4less.com nursece4less.com nursece4less.com 27
prevent drying, the nurse should avoid massaging over bony prominences and should never massage an area that already has skin breakdown or destroyed tissue. 7 The patient may be able to help in some situations where repositioning is necessary. Depending on the patient s condition, the patient may be able to assist by pulling his or her body up using the arms and the side rails while the nurse assists with lifting. If an over-bed trapeze is available, the patient may also use the device to grasp and help with moving up in bed. Alternatively, some patients are unable to help with repositioning or turning while in bed. These patients may be at highest risk of skin breakdown if they cannot relieve areas of pressure that results in tissue destruction. In these cases, the nurse is responsible for regular turning and positioning, assessing the skin for signs of damage, and providing care measures that protect skin integrity. The head of the bed should not be placed at an angle higher than 30 degrees for a patient who has difficulty repositioning in bed. 7 An angle higher than 30 degrees may cause the patient to slide down in bed and not be able to correct the situation. Venous Ulcer Prevention Measures Prevention of venous ulcers focuses on improving the patient s circulation to promote venous return and to prevent pooling of blood in the extremities that can lead to skin breakdown. The nurse should be familiar enough with the patient s disease process to understand the cause of the wound, in order to best avoid performing treatment measures that could possibly make the condition worse. For example, compression stockings are often used in management of venous ulcers but can worsen wounds and ulcers that have nursece4less.com nursece4less.com nursece4less.com nursece4less.com 28
