Edema

Angiogenesis: The process of new blood vessel formation. This process is required for wound healing and allows for the delivery of oxygen and nutrients to the body’s tissues.

Cellular and tissue-based therapies: Advanced therapies that may use cells to induce immunomodulation in the wound bed and facilitate healing by resolving inflammation. Such modalities may include stem cells, scaffolds, skin substitutes, and epidermal substitutes, among others.

Edematous: A term to describe wounds that are affected with edema or are abnormally swollen.

It is important for nurses to strive toward excellence. Our patients deserve the best we are able to give, and sometimes we need to look critically at how we care and how we might improve outcomes. In theory, we update practice because we read research that indicates a change needs to be incorporated into what we do. More often, maybe we follow a colleague and like what we see, or the patient indicates a preference and we change an approach. It may be that a company representative visits and what they say makes sense, has the support of management, and we gladly (or not) incorporate a product into our practice. Looking at a standard of practice and reflecting on how we measure up require honesty and an openness that some might shy away from. Such reflective practice, combined with clinical supervision, leads to high-quality care and is an excellent method of reviewing, updating, and improving practice for patients with problems of the lower leg.

Compression therapy is a well-established treatment modality for a number of conditions, including venous disorders, thrombosis, lymphedema, and lipedema. It is also very effective in treating various kinds of edema.1 Based on patient diagnostic data, many patients with these conditions can benefit from targeted compression therapy.

In a recent survey, we asked our WoundSource Editorial Advisory Board members what outdated wound care practices they continue to see in the field. Depending on what health care setting clinicians work in, there are specific guidelines, policies, and procedures that may impact standard of care. Our board members come from a variety of backgrounds, so their answers varied based on their areas of expertise, but there were a few practices that they could all agree should be left in the past. Do you still use any of these?

Lower extremity ulcers, such as venous and arterial ulcers, can be complex and costly and can cause social distress. An estimated 1% of the adult population is affected by vascular wound types, and 3.6% of those affected are older than 65 years of age. Many factors contribute to lower extremity wound chronicity, including venous disease, arterial disease, neuropathy, and less common causes of metabolic disorders, hematological disorders, and infective diseases. A total of 15% to 20% of lower limb ulcers have a mixed etiology.

Wound healing is a complex biological process that involves a sequence of molecular and cellular events to restore damaged tissue. These events occur within the extracellular matrix, a complex three-dimensional acellular environment that is present within all tissue and essential for life. Remodeling within this extracellular matrix is necessary for tissue repair throughout the wound healing process, including during the inflammatory phase.

Understanding that February is venous leg ulcer (VLU) month, we would be remiss to exclude a consideration of the critically important role played by the lymphatic system. As such, I want to highlight the work of Dr. Tom O'Donnell in a recent editorial written on this subject.

The most common type of chronic lower extremity wound is the venous ulcer, affecting 1% to 3% of the U.S. population. Chronic venous ulcers significantly impact quality of life and are a financial burden for both the patient and the health care system. In the United States, 10% to 35% of adults have chronic venous insufficiency, and 4% of adults 65 years old or older have venous ulcers. Identifying signs of venous disease early on while implementing surgical intervention, if warranted, can increase healing outcomes and decrease the recurrence of venous ulcers. Treatment of venous ulcers can include exercise, leg elevation, dressings, advanced wound care such as cellular and tissue-based products, compression therapy, medications, venous ablation, and surgical intervention.

Edema is the abnormalaccumulation of excess fluid within tissue. The swelling associated with edema can be localized to a small area following an acute injury, it can affect an entire limb or a specific organ, or it can be generalized throughout the entire body. Edema is not a disease, but rather a symptom that can indicate general health status, side effects of medications, or serious underlying medical conditions.

Reflecting back on "In the Trenches With Lymphedema," WoundSource's June Practice Accelerator webinar, many people sent in questions. I have addressed some regarding compression use here.
