Compression therapy is a standard treatment modality for initial and long-term treatment of venous ulcers in patients without concomitant arterial disease. Anna began writing extra materials to help her BSN and LVN students with their studies and writing nursing care plans. Venous ulcers are the most common type of chronic lower extremity ulcers, affecting 1% to 3% of the U.S. population. Severe complications include infection and malignant change. Current evidence supports treatment of venous ulcers with compression therapy, exercise, dressings, pentoxifylline, and tissue products. The healing capacity of the pressure damage is maximized by providing the appropriate wound care following the stage of the decubitus ulcer. Most patients have venous leg ulcer due to chronic venous insufficiency. He or she also performs a physical exam to look for swelling, skin changes, varicose veins, or ulcers on the leg. Dressings are beneficial for venous ulcer healing, but no dressing has been shown to be superior. Slough with granulation tissue comprises the base of the wound, with moderate to heavy exudate. The Unna boot improves healing rates compared with placebo or hydroactive dressings.22,26 However, a 2009 Cochrane review found that adding a component of elastic compression therapy is more effective than inelastic compression therapy alone.45 Also, because of its inelasticity, the Unna boot does not conform to changes in leg size and may be uncomfortable to wear. Signs of venous disease, such as varicose veins, edema, or venous dermatitis, may be present. Continuous stress to the skins' integrity will eventually cause skin breakdowns. It is performed with autograft (skin or cells taken from another site on the same patient), allograft (skin or cells taken from another person), or artificial skin (human skin equivalent).41,42,49 However, skin grafting generally is not effective if there is persistent edema, which is common with venous insufficiency, and the underlying venous disease is not addressed.40 A recent Cochrane review found few high-quality studies to support the use of human skin grafting for the treatment of venous ulcers.41, The role of surgery is to reduce venous reflux, hasten healing, and prevent ulcer recurrence. The treatment goal for venous ulcers is to reduce the edema, promote ulcer healing, and prevent a recurrence of the ulcer. Traditional conservative management of venous ulcers usually entails compression therapy, leg elevation to reduce edema, and dressings on the wound. Two prospective randomized controlled trials reviewed the effect of sharp debridement on the healing of venous ulcers. Encourage deep breathing exercises and pursed lip breathing. Tell the healthcare provider if you have ever had an allergic reaction to contrast liquid. There are many cellular and tissue-based products approved for the treatment of refractory venous ulcers, including allografts, animal-derived extracellular matrix products, human-derived cellular products, and human amniotic membranederived products. St. Louis, MO: Elsevier. The Peristomal Skin Assessment Guide for Clinicians is a mobile tool that provides basic guidance to clinicians on identifying and treating peristomal skin complications, including instructions for patient care and conditions that warrant referral to a WOC/NSWOC (Nurse Specialized in Wound, Ostomy and Continence). It might be necessary to apply the prescription antibiotic cream or ointment directly to the affected area. Citation: Atkin L (2019) Venous leg ulcer prevention 1: identifying patients who are at risk. Contrast liquid is injected into the catheter to help the veins show up better in the pictures. We and our partners use cookies to Store and/or access information on a device. A 25-year-population research found that it typically takes 5 years from the diagnosis of chronic venous insufficiency to the development of an ulcer. It has been estimated that active VU have This hemorheologic agent affects microcirculation and oxygenation, and can be used effectively as monotherapy or with compression therapy for venous ulcers.1,39 In seven randomized controlled trials, pentoxifylline plus compression improved healing of venous ulcers compared with placebo plus compression. She takes the topics that the students are learning and expands on them to try to help with their understanding of the nursing process and help nursing students pass the NCLEX exams. Determine whether the client has unexplained sepsis. Symptoms of venous stasis ulcers include: Risk factors for venous stasis ulcers include the following: Diagnostic tests for venous stasis ulcers usually include: Compression therapy and direct wound management are the standard of care for VLUs. The patient will continue to be free of systemic or local infections as shown by the lack of profuse, foul-smelling wound exudate. All Rights Reserved. How to Cure Venous Leg Ulcers Mark Whiteley. This process is thought to be the primary underlying mechanism for ulcer formation.10 Valve dysfunction, outflow obstruction, arteriovenous malformation, and calf muscle pump failure contribute to the pathogenesis of venous hypertension.8 Factors associated with venous incompetence are age, sex, family history of varicose veins, obesity, phlebitis, previous leg injury, and prolonged standing or sitting posture.11 Venous ulcers result from a complex process secondary to increased pressure (venous hypertension) and inflammation within the venous circulation, vein wall, and valve leaflet with extravasation of inflammatory cells and molecules into the interstitium.12, Clinical history, presentation, and physical examination findings help differentiate venous ulcers from other lower extremity ulcers (Table 15 ). Provide analgesics or other painkillers as directed, at least 30 minutes before caring for a wound. On physical examination, venous ulcers are generally irregular and shallow with well-defined borders and are often located over bony prominences. They typically occur around the medial malleolus, tend to be shallow and moist, and may be malodorous (especially when poorly cared for) or painful. Timely specialized care is necessary to prevent complications, like infections that can become life-threatening. Isolating the wound from the perineal region can occasionally be challenging. Venous leg ulcers are open, often painful, sores in the skin that take more than 2 weeks to heal. If not treated, increased pressure and excess fluid in the affected area can cause an open sore to form. The most common method of inelastic compression therapy is the Unna boot, a zinc oxideimpregnated, moist bandage that hardens after application. There is no evidence that collagenase is superior to sharp debridement.23 Larval therapy using maggots is an effective method of debridement with added potential for disinfection, stimulation of healing, and biofilm inhibition and eradication.24,25 Potential barriers to larval debridement include patient acceptability and pain.26,27 Autolytic debridement uses moisture-retentive dressings and may be used in addition to other forms of debridement. Stockings or bandages can be used; however, elastic wraps (e.g., Ace wraps) are not recommended because they do not provide enough pressure.45 Compression stockings are graded, with the greatest pressure at the ankle and gradually decreasing pressure toward the knee and thigh (pressure should be at least 20 to 30 mm Hg, and preferably 30 to 44 mm Hg). They typically occur in people with vein issues. Stasis ulcers. Teach the caretaker how to properly care for the afflicted regions of the wounds if the patient is to be discharged. Removal of necrotic tissue and bacterial burden through debridement has long been used in wound care to enhance healing. This quiz will test your knowledge on both peripheral arterial disease (PAD) and peripheral venous . document.getElementById("ak_js_1").setAttribute("value",(new Date()).getTime()); This site uses Akismet to reduce spam. Early endovenous ablation to correct superficial venous reflux improves ulcer healing rates. At-home wound healing can be accelerated by providing proper wound care and bandaging the damaged regions to stop pressure injury from getting worse. Further evaluation with biopsy or referral to a subspecialist is warranted if ulcer healing stalls or the ulcer has an atypical appearance. Nursing diagnoses handbook: An evidence-based guide to planning care. Poor prognostic factors include large ulcer size and prolonged duration. Multicomponent compression systems comprised of various layers are more effective than single-component systems, and elastic systems are more effective than nonelastic systems.28, Important barriers to the use of compression therapy include wound drainage, pain, application or donning difficulty, physical impairment (weakness, obesity, decreased range of motion), and leg shape deformity (leading to compression material rolling down the leg or wrinkling). Provide information about local wound care to the patient and the caregiver, and then let them watch a demonstration. There is currently insufficient high-quality data to support the use of topical negative pressure for venous ulcers.30 In addition, the therapy generally has not been used in clinical practice because of the challenge in administering both topical negative pressure and a compression dressing on the affected leg. Contraindications to compression therapy include significant arterial insufficiency and uncompensated congestive heart failure.29, Elastic. Guidelines suggest cleansing of the affected leg should be kept simple, using warm tap water or saline. Duplex Ultrasound Pressure Ulcer Nursing Care Plans Diagnosis and Interventions Pressure Ulcer NCLEX Review and Nursing Care Plans Pressure ulcers, sometimes called bedsores or Decubitus ulcers, are skin and tissue breakdown that arises from exertion of incessant pressure to the skin. Surgical management may be considered for ulcers. There is inconsistent evidence concerning the benefits and harms of oral aspirin in the treatment of venous ulcers.40,41, Statins. These are most common in your legs and feet as you age and happen because the valves in your leg veins can't do their job properly. o LPN education and scope of practice includes wound care. Saunders comprehensive review for the NCLEX-RN examination. Compression stockings are removed at night and should be replaced every six months because of loss of compression with regular washing. 2 In some studies, 50% of patients had venous ulcers that persisted for more than 9 months, and 20% had ulcers that did . Patient information: See related handout on venous ulcers, written by the authors of this article. Impaired Skin Integrity ADVERTISEMENTS Impaired Skin Integrity Nursing Diagnosis Impaired Skin Integrity May be related to Chronic disease state. After administering the analgesic, give the patient 30 to 60 minutes to rate their acute pain again. Examine the patients vital statistics. The consent submitted will only be used for data processing originating from this website. For wound closure to be effective, leg edema must be reduced. Associated findings include lower extremity varicosities, edema, venous dermatitis, and lipodermatosclerosis. Buy on Amazon, Ignatavicius, D. D., Workman, M. L., Rebar, C. R., & Heimgartner, N. M. (2020). An example of data being processed may be a unique identifier stored in a cookie. These measures facilitate venous return and help reduce edema. However, data to support its use for venous ulcers are limited.35, Overall, acute ulcers (duration of three months or less) have a 71 to 80 percent chance of healing, whereas chronic ulcers have only a 22 percent chance of healing after six months of treatment.7 Given the poor healing rates associated with chronic ulcers, surgical evaluation and management should be considered in patients with venous ulcers that are refractory to conservative therapies.48.
