One of the greatest challenges when dealing with biofilms in chronic wounds is identifying their existence in the first place. The extracellular polymeric substance or EPS coating on biofilms essentially is an invisible cloak that protects and hides biofilms from both the body's immune system and antimicrobial therapies. This biofilm property keeps the wound from advancing through the phases of wound healing and thus remaining in the inflammatory phase, thereby allowing further proliferation of biofilms.

wound healing and wound bed preparation

by Martin D. Vera, LVN, CWS

Wound bed preparation has become the gold standard model for proper wound assessment. It allows us clinicians to identify and breakdown local barriers to wound healing. Throughout our health care careers, we have seen it over and over again: the collective emphasis on standards of care, evidence-based practice, and cost-effectiveness in order to achieve positive outcomes for our patients.The wound bed preparation model supports all of these aspects of care delivery.

Editor's note: This post is part of the Temple University School of Podiatric Medicine (TUSPM) journal review club blog series. In each blog post, a TUSPM student will review a journal article relevant to wound management and related topics and provide their evaluation of the clinical research therein.

wet-to-dry dressing changes using gauze


The big debate continues in regards to using wet-to-dry dressings. One thing that is for certain though is that this type of dressing is frowned upon in long-term care facilities per the National Pressure Ulcer Advisory Panel (NPUAP) Guidelines for pressure ulcers. However, long-term care facilities are put at risk for citations when using wet-to-dry dressings for any wound type.

One of my favorite topics to discuss in wound care is biofilms. When I conduct wound care in-services or trainings, I always ask the audience, "Who wants to tell me what a biofilm is?" There is silence. From that point, I proceed to tell my little story about biofilms. It sounds a little like this...

scapel for debridement

There are a number of general rules in surgery. Among these: dead space has to be avoided. interestingly enough, there is virtually no real scientific documentation about this topic but everybody knows this to be true (in ulcers this, of course, applies to fistulae, crevices, etc.). Another general rule is that dead tissue and foreign bodies have to be removed since they are dangerous to the body. Dead tissue (necrosis and slough) is a breeding ground for bacteria, leading to infection (and sepsis) and releases toxins into circulation.

wound care 101 - wound debridement

by Laurie Swezey RN, BSN, CWOCN, CWS, FACCWS

There are four main types of wound debridement: mechanical, autolytic, enzymatic, and surgical. Each form of debridement has its own advantages and disadvantages. Let’s take a look at each method individually:

In the beginning, long before Johnson met Johnson and Band-Aids were invented, primitive men and women suffered minor cuts and abrasions and probably left them uncovered to heal. After all, the bleeding had stopped, a scab eventually formed and experience had taught them that their skin would heal in a week or two. So there was no great rush to find a use for those puffy, cottony, soft, white plants growing in the fields just yet.

Necrotic tissue that is present in a wound presents a physical impediment to healing. Simply put, wounds cannot heal when necrotic tissue is present. In this article, we'll define necrotic tissue and describe ways to effect its removal from the wound bed.

Finding the key to unlocking a non-healing chronic wound keeps us awake at night. Though we have, as bedside clinicians, learned much about the physiology and biochemistry of chronic wounds over the past decade, wound healing is not an exact science. Negative pressure wound therapy (NPWT) has become standard care for certain chronic wounds. Sometimes, however, wounds treated with this therapy do not progress as readily as we think that they should. This has led us to consider combining other wound care products with NPWT. This article will examine the rationale for using three products in combination with negative pressure.
