The Wound Healing Process

Promoting the wound healing process is a primary responsibility for most health care practitioners. It can take 1-3 days for a closed wound to actually establish a seal. Infections usually occur in 3-6 days but may not appear for up to 30 days, according to the CDC guidelines for preventing surgical infections.

wound care assessment system

by Amanda Steinhauser, LVN, WCC

Everyone has heard the numbers; wound care costs in the United States are reported to be in excess of fifty billion dollars annually. Moreover, more than six million Americans suffer from chronic wounds. According to the American Diabetes Association, over one million Americans are diagnosed with diabetes every year. Despite these jaw-dropping statistics, wound care assessment techniques remain, for the majority, one of the most antiquated parts of health care.

Zinc in wound healing

by Aletha Tippett MD

Well, what a surprise to find that what you have been doing all along is really the right thing to do even though you didn’t know the reason. Always, over the years doing wound care, I applied a thick layer of zinc oxide ointment around the patient’s wound, then put my dressing on the wound and covered it with a topping, usually plastic wrap pressed into the zinc oxide ointment.

venous assessment

Wound clinicians across the nation (and the world) are commonly faced with the difficult task of managing lower extremity wounds. Lower extremity wounds come in many different forms. We are not faced with a generic type, but several—in fact, we never know what we'll be presented with day-to-day.

delayed wound healing

by Janet Wolfson PT, CLWT, CWS, CLT-LANA

Delayed wound healing: how did it start, what are we doing to prevent delay, and what could we be doing differently when delay is noted?

If you have worked in wound care a long time, there are those wounds we recall that were a real puzzle. Why wouldn't they heal when we were doing everything right? Sometimes it is as simple as finding out that the client has been sleeping in a recliner instead of a bed, in which case edema and sacral wounds will suffer. Or perhaps that the patient has resumed smoking now that their mobility allowed getting outdoors.

literature review

Chronic wounds are clinically defined as wounds that have failed to proceed through a healing process in a timely and biologically efficient manner. They are easily identified due to their presence of a raised, hyperproliferative, and non-advancing wound margin. They often are not responsive to initial therapy, and still continue to exist even with adequate wound treatment and sharp debridement.

Keloids are fibrous lesions made of collagen types I and III that arise from an area of wound healing, outside the margins of the original wound and are an unfortunate consequence of irregular wound healing. Treating keloids is difficult because there is limited understanding on why they arise, which is why many treatments fail to prevent their recurrence. It has been shown that no single treatment modality is effective to treat keloids; therefore, a multifaceted approach must be taken to lower recurrence rates.

Diabetic foot ulcers often present in patients with diabetes mellitus, and are a serious and challenging complication that often requires time and costly procedures to treat. Diabetic foot ulcers are very difficult to heal and often become chronic, which increases the incidence of progressing to infection. The goal of diabetic foot ulcer management is to promote reepithelization of ulcerative areas, as well as address deficits of the ulcer such as necrotic tissue, inadequate perfusion, and inflammation.

Wound healing occurs in four phases: hemostasis, inflammation, tissue growth, and tissue remodeling. The process of wound healing can be affected by multiple factors, including oxygenation, age, stress, and disease such as diabetes. Wound healing in patients with diabetes can be further complicated by neuropathy and vascular disease. Typical treatments for diabetic wounds, like wound dressings, cell therapy, and oxygen therapy, are not entirely successful because diabetes slows and impairs the healing process. The authors of this study propose the use of a non-thermal atmospheric pressure plasma treatment as a novel therapy for diabetic wounds. Unlike conventional methods, this treatment can accelerate tissue repair without negatively affecting normal tissue. Using atmospheric plasma accelerates tissue repair because the plasma produces reactive oxygen and nitrogen species, which are key for the inflammatory response. It also induces neovascularization and enhances epidermal layer formation.

Venous leg ulcers (VLUs) affect 3% of all people aged 65 years and older. After healing, the recurrence rate can be as high as 69%, making the treatment of VLUs costly to the healthcare system. In Australia alone, VLUs cost the healthcare system $400-500 million per year. VLUs are problematic for patients beyond the physical ulceration of their feet because they create social and psychological challenges. Therefore, treating a VLU entails not only closing the ulcer with full epithelialization, but also taking the correct measures to prevent its recurrence.
